Publisher: 2015Dissertation note: Parasitic problem has been a major mounting problem of equids which severely creates the
hindrance in performance in equine which leads to weakness, emaciation, colic, diarrhea, anemia,
thriftiness, loss of energy and ultimately death. Looking at the importance of equine and its
utilization by poor farmers there is need to cure the malady.
GIT Nematodes are prevalent in Equines in district Jhang. Novel combination of
Abamactin + Praziquantel was very efficacious to subside parasitic load in Equines. GIT
Nematodes have some effects on blood parameters (TEC, HB, and PCV).
A total 200 (100 horses and 100 donkeys) from different areas of district Jhang were
included in the study. For this, fresh fecal sample were carefully collected into a sealed container
from each horse and donkey and were transferred to Medicine lab, UVAS, Lahore in containers
with ice packs. Each samples were examined for nematodes eggs and for larvae by using different
techniques i.e. Direct Smear Method and fecal culture technique while the eggs count was
performed by McMaster technique. To study the effect of Gastrointestinal nematodes on various
blood parameters of equine, blood samples were collected from selected animals and were
analyzed for hemoglobin (Hb), total erythrocytes count (TEC) and packed cell volume (PCV) by
using Hematology Analyzer. For therapeutic trails, a total of 12 horses and 12 donkeys positive
for nematodes were taken and divided into groups A, B and C comprising of 8 animals each. Group
C was comprised of 8 animals as Positive control and fourth group D was comprised of 8 animals
as negative control. Group A was treated with abamactin + praziquantel (EQUITAK) orally @
1ml/20kg bodyweight PO once at 0 day and group B was treated with herbal ingredients
Summary
49
(EVERZAN) @ 1ml/20kg bodyweight PO once at 0 day. Efficacy was determined on the basis of
reduction of eggs in feces at day 0, 7th and 21th day (post-treatment). Data was recorded in a
questionnaire regarding age, sex, breed, nutritional status and disease condition.
The present study was designed to check the comparative efficacy of two different drugs
such as Equitak (Allopathic) and Everzan (herbal) against gastrointestinal nematodes and its
effects on blood parameters in both horses and donkeys. According to therapeutic trial, Equitak
presented very good response against GIT nematodes by fast decreasing EPG in both experimental
animals and showed its efficacy more than 80% but Everzan showed poor response against
nematodes in both experimental animals and its efficacy less than 30%. By administering Equitak
in both experimental animals gave good results regarding blood parameters such as total
erythrocytes count (TEC), packed cell volume (PCV) and Hemoglobin (Hb) and its values had
been continuously increasing in 7th and 21st day since administration. But in contrast to Equitak,
Everzan showed poor response regarding blood parameters and values did not increased at 7th and
21st days. It has been proved that Equitak has its very strong effect against strongylus spp than
other parasites that come under the category of roundworms. So Equitak proved more effective
against nematodes in Equines than Everzan. Availability: Items available for loan: UVAS Library [Call number: 2418-T] (1).

by Hafiz Manzoor Ahmad (2013-VA-856) | Dr. Hamad Bin Rashid | Prof. Dr. Muhammad Arif Khan | Dr. Asim Khalid Mahmood.
Material type: Publisher: 2015Dissertation note: Mostly of the drugs given intramuscularly are ineffective in producing anesthesia in ducks. There are some combinations which have a synergistic effect for producing good sedation and analgesia. This combination includes ketamine-xylazine and ketamine-xylazine-diazepam. This study was conducted on ducks which are divided into two groups (A, B). The group A was given xylazine (5 mg/kg) and ketamine hydrochloride (15 mg/kg) and the birds of group B was given ketamine hydrochloride (15 mg/kg), xylazine (2.5 mg/kg) and diazepam (2.5mg/kg) cocktail. Anesthesia is the desensitization of body through nerve blockage. It is the reversible state of analgesia and loss of responsive-ness, loss of skeletal muscle reflexes, decreased stress response, or all of these simultaneously. The average body temperature of ducks treated with KX and KXD was 105.02±0.12, and 104.97±0.18 oF, respectively. The average heart rate of ducks anesthetized by KX and KXD was 103.75±3.18, and 98.63±2.24 beats/min, respectively. The average respiratory rate of ducks treated with KX and KXD was 19.2±1.62, and 16.11±0.52 breaths/min, respectively. The onset of sedation in ducks anesthetized by KX, and KXD was recorded in 2.11±0.75 and 1.14±0.04 minutes after drug administration. The duration of sedation in the ducks anesthetized was 87.33±6.74, and 127.42±18.60 minutes, respectively. The recovery of ducks from sedation was recorded in 89.53±6.22, and 128.56±18.52 minutes. Onset of analgesia in ducks anesthetized by KX and KXD was recorded in3.22±0.54, and 1.67±0.77 minutes after drug administration. The duration of analgesia in the ducks anesthetized with KX and KXD was 39.76±3.89 and 81.15±11.17 minutes, respectively. The recovery of ducks from analgesia was recorded in 43.37±4.42 and 82.82±11.15 minutes, when anesthetized with KX and KXD respectively. The onset of sedation, onset of analgesia, duration was relatively delayed in KX

Publisher: 2015Dissertation note: The native breeds of Aseel chicken are playing vital role by producing organic meat and eggs. The Aseel chicken breed has some advantage as compared to other native breeds like, Lyallpur Silver black and Desi for their growth traits. However the growth and production traits need to be enhanced. There is no commercial farming system of Aseel chicken due to its poor fertility and hatchability. To overcome these problems the breeding roosters must be physiologically elite having excellent semen quality for better growth and egg production. The objective of this study was to enhance the semen quality, fertility and hatchability of Aseel roosters by the process of induced molting. For this purpose molting was induced in the 3 old males. There were three groups of Aseel Lakha cockerels’ i.e. molted, non-molted and fresh. The research was performed at Indigenous Genetic Resource Center (ICGRC), Department of Poultry Production, Ravi Campus, Pattoki.
To evaluate the impact of induced molting on semen quality, fertility and hatchability followed by natural mating of females to get better fertility and hatchability in eggs. Six Aseel roosters up to 60 weeks of age having 3.5 to 4kg body weight were divided into two groups’ as molted and non-molted. Third group of fresh birds more than 30 weeks of age were selected in this experiment as control. In one older group molting was induced by feed restriction. After completion of molting, two weeks rest was given to birds to recover body weight. These birds were trained for semen collection by abdominal massage method for two weeks. Semen was brought to the laboratory for evaluation after collection in all three groups. The significant difference (P < 0.05), was observed for volume, concentration, motility, livability and morphological defects in molted, non-molted and fresh groups. Eggs collected from the females mated with three groups were stored at 40C for two weeks. After that these

fertility, infertile eggs, and dead germs, dead in shell and hatchability% were recorded in three experimental groups. There was significant difference (P < 0.05), between fertility % infertile eggs % dead germs % and hatchability %. It is concluded that the semen quality is improved by the process of induce molting. Further egg sets from the females mated with induced molted males’ yielded better fertility (77%) and hatchability (54.1%) in indigenous Aseel chicken so induced molting is a better tool for the old males after 60 weeks of age for their reproductive performance.

Publisher: 2015Dissertation note: Phytomedicines mark the major component of health care as natural medicines have always provided the strong foothold for the discovery and manufacturing of synthetic drugs. So plants are a rich source of bioactive compounds having many therapeutic activities and majority of them are still untapped. Eucalyptus globulus is a medicinal plant known for its value to cure asthma, respiratory infections, cough and allergic reactions. The antimicrobial activity, insecticidal and hypoglycemic activity have also been credited to the plant. Most of the studies have been conducted on the essential oils of Eucalyptus globulus and little work has been reported on extracts. Whereas, sequential extracts has not been employed yet.
Hexane, chloroform and ethanol, aqueous extracts were prepared by the sequential extraction on Soxhlet apparatus and antibacterial activity was evaluated against Staphylococcus aureus, Escherichia coli, Salmonella enterica, Clostridium perfringens type A and Haemophilus paragallinarum by agar well diffusion and micro broth dilution method. The zones of inhibition and minimum inhibitory concentration were determined. The extracts showing antimicrobial activity were further evaluated for cytotoxicity by using MTT assay on Vero cell line. The cell culture media was prepared and cell lines were propagated to form monolayer then monolayer was exposed to plant extract dilutions. After 24-48 hours, MTT dye was introduced and cell survival percentage was calculated.
The statistical analysis was conducted with help of Statistic Package for Social Sciences (SPSS for windows version 16, SPSS inc, Chicago, IL, USA) and results were compared using one way ANOVA.
Summary
89
The zones of inhibitions showed by hexane, chloroform, ethanol and aqueous leaf extracts of Eucalyptus globulus against Staphylococcus aureus were 0.0, 19.3, 20.3 and 23.3mm; against Clostridium perfringens type A were 14, 22.3, 14.0 and 15.3mm; against Escherichia coli were 0.0, 12.6, 13.3 and 15.6mm; against Salmonella enterica were 10, 12.3, 18.6 and 21mm; against Haemophilus paragallinarum were 0.0, 8.6, 14 and 18mm respectively. Hexane extract showed no zone of inhibition against Staphylococcus aureus, Escherichia coli and Haemophilus paragallinarum.
The MICs values of hexane, chloroform, ethanol and aqueous leaf extracts of Eucalyptus globulus against Staphylococcus aureus were 0.00, 104.1, 32.55 and 312.5 μg/ml; against Clostridium perfringens type A were 52.08, 39.06, 16.27 and 312.5 μg/ml; against Escherichia coli were 0.00, 78.12, 260.4 and 625.0 μg/ml; against Salmonella enterica were 13.02, 104.1, 130.2 and 416.6 μg/ml; against Haemophillus paragallinarum were 0.00, 104.1, 260.4 and 416.6 μg/ml respectively. MIC was not performed against Staphylococcus aureus, Escherichia coli and Haemophilus paragallinarum for hexane extract as no zone of inhibition was observed against them.
Hexane extract of Eucalyptus globulus was cytotoxic at concentration ≥ 312.5μg/ml, chloroform extract at concentration ≥ 375μg/ml, ethanol extract at concentration ≥ 625μg/ml and aqueous extract was cytotoxic at concentration ≥312.5 μg/ml.
The indigenous plant Eucalyptus globulus has antibacterial activity against common poultry pathogens and can be helpful for development of new drugs of plant origin. Availability: Items available for loan: UVAS Library [Call number: 2429-T] (1).

Publisher: 2015Dissertation note: Non-steroidal anti-inflammatory drugs play a vital role due to their multi therapeutic approach. In this study, the antiviral activity of indomethacin, naproxen, and mefenamic acid against avian influenza H9 virus was evaluated In ovo. The stock solutions of each drug were prepared in their perspective solvent and preserved. From the stock, three different dilutions (10µg/ml, 20µg/ml, 40µg/ml of indomethacin, 25µg/ml, 50µg/ml, 100µg/ml of naproxen and 20µg/ml, 40µg/ml, 80µg/ml of mefenamic acid) of each drug were prepared. For each of drug to be tested, 25 embryonated chicken eggs were assigned to 5 groups having 5 eggs each, to evaluate both antiviral activity and embryonic toxicity parameters.
For evaluating antiviral activity, the groups of embryonated chicken eggs were inoculated with 4HA virus, antibiotics and different concentrations of indomethacin, naproxen and mefenamic acid. For evaluation of embryonic toxicity, embryos of each group were injected with normal saline, antibiotics and different concentrations of indomethacin, naproxen and mefenamic acid. Two controls i.e. positive control of virus (received 4HA Virus only) and negative control (received normal saline) were also included to validate the test results.
With avian influenza H9 virus the different concentrations of each drug were mixed and 0.2 ml of this suspension was inoculated to 9th to 10th day embryonated eggs along with positive and negative controls having only virus and normal saline respectively. Amantadine, standard drug, was inoculated by following the mentioned manner. These inoculated embryonated chicken eggs were incubated at 37oC and were checked after 12 – 72 hours. After 72 hours of post inoculation, chilling was done by placing all the eggs at 4oC in fridge for overnight section of time and the allantoic fluid was collected.
The embryo survival percentage, positive or negative spot haemagglutination activity and determination of virus titre by haemagglutination test confirmed the antiviral activity. The embryonic toxicity effects of indomethacin, naproxen, mefenamic acid and amantadine were assessed by only inoculating the drug of respective concentrations as used for antiviral activity in embryonated chicken eggs and incubating for 72 hours. Among the three non-steroidal anti-inflammatory drugs (NSAIDs), indomethacin showed significant antiviral activity against influenza H9 virus as compared to naproxen and mefenamic acid. Naproxen showed antiviral activity against influenza H9 virus greater than that of mefenamic acid. However, antiviral activity of mefenamic acid as compared to naproxen and indomethacin is negligible against influenza H9 virus when confirmed by Spot Hemagglutination test while reduction in viral titre was observed by Hemagglutination test.

Publisher: 2015Dissertation note: Theileriosis is the destructive disease caused by the protozoan in cattle. It is major cause of huge losses in production of cattle. It is a wide spread protozoan syndrome of cattle playing foremost role in production losses. Early and exact diagnosis of theileriosis can be helpful in reducing production losses.
Early and exact diagnosis of theileriosis can be helpful in the control of disease.( Hypothesis )
Incidence of different Theileria species was recorded. Blood samples was collected in sterilized vacutainers. The samples were examined by preparing fresh blood smears followed by Giemsa staining and observing under microscope. Identification on preliminary basis was done by morphological characters of Theileria. In order to find the harmful effect of the theileriosis, blood hematology and biochemistry values were also be determined in both healthy and infected cattle.
The samples from theileriosis positive animals were used for nucleic acid extraction. The extracted nucleic acid was amplified using Species specific primers.Agarose gel electrophoresis was used to visualize the amplified DNA. Amplicons of nucleic acid was treated with different restriction enzymes and pattern was visualized to find differences among different species of Theileria.
Suitable statistical tool was used to analyze the data collected. Chi was applied on data by using statistical software SPSS version 20.0. This research will help to confirm for the conventional and molecular diagnosis of theileriosis in dairy animals. Also genetic variation in Theileria species will be determined.

Publisher: 2015Dissertation note: Livestock in Pakistan is an integral part for all systems of farming and is considered as cash income on daily basis for small holders. From economy point of view, buffalo has much importance and used for draught, meat and milk purposes. Out of the total animal’s population, up to 47 percent dairy population comprises on Buffaloes. Globally minute study has been documented on pathological investigations of liver in Buffaloes and very rare is documented in Pakistan.
The present study was designed to investigate histopathological liver lesions in Buffaloes at Shahpur Kanjra slaughter house located in District Lahore. A total of 100 diseased liver samples of Buffaloes were brought to the department of Pathology, University of Veterinary and Animal Sciences (UVAS), Lahore. These samples were examined for gross pathological lesions such as presence of abscess, hemorrhages and Hydatid cysts along with thickness, color and texture. For histopathological studies we persevered these samples in 10% neutral buffered formalin solution. Paraffin embedding technique was used to process the samples which were stained by Haematoxylin and Eosin method.
The results of our study revealed percentages of different diseased conditions in the Liver tissues of slaughtered buffaloes. The percentage of Hydatidosis was found high among all the conditions and reported as 28 percent. The conditions of the Amphistomiasis were reported as 22 percent. While Cirrhosis disease was prevalent in the buffaloes at the rate of 18 percent. The percentage after the cirrhosis was found for the condition of Granulomatous hepatitis which was

16 percent. The percentages of Abscess, Fascioliasis and Haemorrhages were found as 7, 6 and 3 percent respectively.
In conclusion, theses above mentioned pathological conditions reported in our study served as major cause of liver condemnation at Shahpur Kanjra slaughter house of Lahore District, which may also contributed the economic losses. To mitigate the economic and public health impacts proper deworming plan along with good animal husbandry practices would probably be effective in decreasing incidence of these Liver diseases.

by Sohrab Ahmad (2014-VA-529) | Prof. Dr. Habib ur Rehman | Dr. Muhammad Shahbaz Youaf | Dr. Rahat Naseer.
Material type: ; Literary form:

Publisher: 2016Dissertation note: Rice is the second major cereal crop cultivated in Pakistan. The rice crop‘s residual parts, i.e. straw and husk are used as an animal feed. To enhance the nutritive value and digestibility of these residues different treatments are used, including Physical, Chemical and Biological treatments to enhance animal performance. In the present study, the effect of Physical, Chemical and Biological treatment of rice husk was observed on the serum mineral profile which is also an indicator of an animal’s performance.
Thirty six adult sheep were divided into six groups. Negative control group 1, positive control 2, physically treated group 3 acid treated rice feeding group 4, alkali treated rice husk group 5, and biologically fermented rice husk group 6. Each group received 20% treated rice husk along with the routine ration. Blood was collected at day 60 and serum was separated, which was analyzed for minerals by using atomic absorption specrophotometrery and flame photometry.
Data was analyzed using SPSS software. One-way ANOVA was applied on data to observe among the group difference while group differences were compared by Duncan’s Multiple Range Test. Differences were considered significant at P < 0.05.
The results revealed that serum level of zinc was significantly higher (p < 0.05) in group 6 compared to group 4 and 1 but similar to group 2 and other treatment groups (figure 1). However, we found a tendency towards significance (p=0.056) in serum calcium level, which was higher in group 5 compared to other treatment groups and group 1 but was found similar to group 2. The serum sodium level also showed a trend towards significance (p=0.072) in group 2, 3 and 5 compared to group 6. Serum iron and potassium level were found non-significant (p<0.05) in all treatments groups compared to group 1 and 2. Blood hemoglobin level was found significantly higher (P=0.013) in control positive group compared to control negative group, 3, 4, 5and was similar to group 6. The platelet count was found in a tendency towards significance (P=0.062), higher in all treatment groups compared to the negative control group. The hematological parameters, i.e. RBC, WBC, MCV, MCH, and MCHC were found non-significant (p< 0.05) in both the control groups and all treatment groups.
Concluding the above discussion, we suggest that fermented rice husk feeding may have better effect on the animal n terms of increase in minerals retention and hemoglobin level in the blood which will cause an increase in the metabolic activities and hence growth of the animal.

Publisher: 2016Dissertation note: Sahiwal cow is the best milch breed among all Bos indicus throughout the Subcontinent. It is famous for heat resistance, tick tolerance, high milk production. It is also exported to different countries for its peculiar properties. These cows have low fertility when inseminated with frozen semen. Very little fragmented experimental data is available on reproduction of Sahiwal breed, which might be major reason of bad performance from reproduction aspect. The same rule of insemination as we know in Holstein (Bos taurus) when applied on our local animals did not yield similar results. The designed experiment was to determine appropriate time of insemination to improve reproductive efficiency in Sahiwal cows.
This experiment was conducted at Livestock Experimental Station Jahangirabad, District Khanewal Punjab. Eighty five (n=85) adult, multiparous, lactating Sahiwal cows having BCS ≥ 2.5 and weight 325–450 kg, more than 60 days post-partum with normal reproductive tract were selected for this study. Estrous detection was carried out twice daily with teaser bull for 30-45 minutes. Standing heat was considered when cow did not move away for 4-6 seconds with teaser bull being mounted on her. Cows were assigned randomly into four groups (0 h, 12 h, 24 h and 36 h) with respect to standing heat. Frozen semen from bull whose fertility is known to us having post thaw motility of 40% at least was used for insemination.
Ultrasound was used as tool for precise assessment of reproductive status of experimental animals. At the start of each replicate, both ovaries and uterus of all the adult Sahiwal cows were scanned with B-Mode Ultrasound console for presence or absence of fetus and CL or any structural abnormality, with help of 7.5MHz Trans-rectal probe. Pregnancy was diagnosed 35 day post AI. Results were analyzed by using statistical software (SPSS). Pregnancy per AI was compared amongst

different insemination groups by using binary logistic regression test. Pregnancy was assessed retrospectively by plotting scatter graph using ovulation as our reference point.
The timing of ovulation was 20.64 hours from onset of standing heat. Mean size of ovulatory follicle at 0, 12, and 24 hour after standing heat was 13.52 mm, 14.52 mm and 15.39 mm respectively. The ovulation rate was 97%. Highest pregnancy per AI 57% (13/23) was observed in 0 h group, followed by 36% (8/22) in 12 h, followed by 25% (5/20) on 24 h group. Lowest pregnancy per AI 10% (2/20) was seen in group inseminated 36 hour after onset of standing heat (36 h). While retrospectively highest pregnancy per AI 67% (10/15) was observed in -18 h group, followed by 29% (6/21) in -6 h group and 32% (7/22) in +6 h group, while no pregnancy were observed 0% (0/12) in +18 h group. The overall pregnancy per AI was 33% (28/85) in Sahiwal cows. Availability: Items available for loan: UVAS Library [Call number: 2468-T] (1).

Publisher: 2016Dissertation note: Our water buffalo (Bubalus bubalis) has much potential for production of milk. But this
animal has some problems regarding reproduction including delayed puberty, poor estrus behavior,
silent heat, long postpartum period and low conception rate by artificial insemination. This leads
to poor reproduction and hence great economic loss. Therefore, the requirement is to address these
problems efficiently and formulate more effective techniques for improvements. Researchers have
devised many estrus synchronization protocols (PGF2α, P4, GnRH, eCG, hCG etc.) that help
bringing many animals in heat and hence improve the reproductive performance when fixed time
artificial insemination is combined with them. But these protocols give inconsistent results when
they are applied on buffaloes making it necessary to improve the techniques.
This study was planned on the hypothesis that presence of bull (bio-stimulation), at the
time of synchronization, may play an important role in enhancement of estrus intensity and fertility
rate in Nili-Ravi buffaloes. Seventy one adult buffaloes were randomly selected from different
areas of field conditions and LRS (NARC) and subjected to CIDR based heat synchronization in
combination of either bio-stimulation or non-stimulation. The animals were observed for
behavioral estrus signs twice a day starting after 12 hours of CIDR removal till 96 hours.
Pregnancy diagnosis was done by rectal palpation 60 days post CIDR removal. Estrus response
and pregnancy rate were analyzed by Chi-square test using MINITAB version 15. Estrus signs and
total estrus intensity were compared by Mann Whitney U test. Difference was considered
significant at probability level of (P < 0.05).
In peri-urban areas, more animals from bio-stimulated group showed better behavioral
estrus signs, more total intensity score and significantly higher pregnancy rate as compared to nonSUMMARY

stimulated group of animals. At LRS (NARC), more animals from non-stimulated group were
found in behavioral estrus but intensity of heat signs was high in bio-stimulated animals.
Pregnancy rate was also higher in non-stimulated animals but the difference was not significant.
Overall, in this study, we got higher pregnancy rate in bio-stimulated animals than non-stimulated
group which indicates a positive response of bull stimulation on reproductive performance of Nili-
Ravi buffaloes who were synchronized with CIDR based estrus synchronization protocol. Availability: Items available for loan: UVAS Library [Call number: 2469-T] (1).

Publisher: 2015Dissertation note: Hydatidosis is important zoonotic and economic disease of livestock and human beings.Hydatid cyst is larval form of genus Echinococcosis Granulosis. Hydatidosis causes considerable economic loss in livestock due to condemnation of organs. Dogs are the primary definitive hosts for this parasite, with livestock acting as intermediate hosts and humans as aberrant intermediate hosts. The outcome of infection in livestock and humans is cyst development in the liver, lungs, or other organ system. The disease is spread when food or water that contains the eggs of the parasite is eaten or by close contact with an infected animal. The eggs are released in the stool of meat-eating animals that are infected by the parasite. For these animals to become infected they must eat the organs of an animal that contains the cysts such as sheep or rodents.The type of disease which occurs in people depends on the type of Echinococcus causing the infection. It is a type of worm infection and is a neglected tropical disease.
To find out the prevalence of Hydatid cyst in small Ruminants, total 300 samples were studied from 300 samples, 150 were of sheep and 150 samples were of goat.Among those samples infected organs of animal like liver ,lung heart were separated in sterile container.then hydatid cyst fluid be obtained by penetrating the needle into cyst wall .A drop of cyst fluid was taken on microscopic Glass slide and cover slip was applied on it and observed under microcope for motility of flame cells to see viable protoscoleces ,live and movable protoscoleces identify as fertile cyst.
Summary
Conclusion
This study Will be helpful to acess the prevalence of zoonotic hydatid cyst disease in the Punjab, Dera Ghazi Khan area and surroundings.And study ultimately help us to control the spread of zoonotic infection and we were be able to guide public to adopt preventive mesures against the disease.

Publisher: 2016Dissertation note: The present study was conducted in the Kalabagh game reserve (KGR) from July 2015 to April 2016. The surveys were conducted with the help of managing and supporting staff from Kalabagh wildlife Foundation in order to know the diversity and various threats to amphibians and reptiles in the study area.
A total 23 species belonging to three orders, 16 families and 23 genera were recorded including six amphibians and 17 reptiles. Amphibians included one toad and five frogs whereas; reptiles included one turtle, ten lizard and six snake species. Three species out of the six recorded snakes are venomous rests all the amphibian and reptiles are non-venomous. All the recorded species were captured directly.
Amphibians were searched actively in their potential breeding areas and resting places like ponds, water channels and along streams during day and night. Simple hand nets or scoop nets were used for amphibian collection; however, calling males are best caught by hands. Hand picking through bare hands or with the help of long forceps or snake clutch has always been the most efficient way of collecting different reptiles. . Snakes were mostly collected using snake catcher and every snake being collected was considered as venomnous in order to avoid any mishap. Road-Killed snakes were also collected.
Following the specific criteria , two species were evaluated as Abundant, eight species as Common, and five species as Fair, one species as Rare and seven species as Occasional.
Out of the recorded 23 species, two reptiles were found among endemic species to Pakistan including one lizard; Salt range ground gecko and one snake; slender blind snake.
Six of the recorded 23 species are CITES Species with one species (Varanus bengalensis) is enlisted in Appendix I, while five species (Hoplobatrachus tigerinus, Lissemcieys punctata, Eryx johnii, Uromastyx hardwickii and Naja naja,) are enlisted in Appendix II of the CITES category 2016. The only one species Varanus bengalensis is having decreasing IUCN population trend.
There are some potential threats to herps in the study area. Some snakes that get trapped are killed by the local residents. The Spiny tailed lizard is also captured by some hunters for sale to local Hakeems to extract oil. Black cobra is captured by snake charmers to entertain people and for extraction of venom. The evidences reveal that the populations of various amphibians and reptiles including snakes in the study area are not facing any decline rather they are stable except spiny tailed lizard and Bengal monitor. Most of the recorded herps from the study area also occupy a vast distribution in the country. No crocodilians and tortoises are found in the study area. The existing herps include; frogs, toads, freshwater turtles, lizards and snakes.

Characterization And Thermostability Of Phytase Produced By Indigenous Aspergillus Niger Isolates
by Madeeha Tariq (2010-VA-293) | Prof. Dr. Aftab Ahmad Anjum | Dr. Jawad Nazir | Dr. Wasim Shehzad.
Material type: ; Literary form:

Publisher: 2016Dissertation note: Phytase enzyme now becomes more important commercially. Presence of phytate in food
and feed make them less nutritive due to phytate complexes mainly with mineral ions and
proteins. Phytase in monogastric animals and human stomach either produced in small amount or
not. This leads to phosphorous Pi deficiency. Supplementation of food and feed with phytase
enzyme full fill this deficiency through degradation of phytate complexes and release of Pi.
Degradation of phytate complexes makes phosphorous other mineral ions and amino acids
available for growth and development. It was proved that feed conversion rate in poultry
increased due to supplementation of phytase in poultry feed. Feed of monogastric animals mostly
at industrial level pelleted to give it a shape or to kill microorganisms (sterility). At industrial
level enzyme production and processing cost about 2 billion. So this demands a thermostable
phytase to use at industrial level or its cost effective production.
Aspergillus niger have been used industrially for production of beneficial enzymes. A.
niger isolates procured from department of microbiology were confirmed through macro and
microscopic characteristics as A. niger. These isolate were screened for phytase production on
phytase screening medium PSM agar. Positive isolates identified through noval staining using
2% cobalt chloride, 6.25% ammonium molybdate and 0.42% ammonium vanadate for contrast.
Positive isolates next proceeded for phytase enzyme production in broth media (pH 5.6) using
0.5% sodium phytate as substrate. Incubation was done at 30oC for 5-7 days in shaking incubator
150rpm. After production quantification of enzyme was carried out through enzyme activity
assay. There maximum (274.99±10.14 FTU/ml) and minimum (68.88±2.55 FTU/mL) activity of
phytases from isolate PASN01 and PASN08 was observed. Phytases characterized through sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) to know protein
molecular weights. Highest molecular weight 107.82kDa was PASN06 and lowest was 35.21kDa
of PASN 01.
Aspergillus niger spores subjected to steam heat treatment at 30oC, 45oC, 60oC, 75oC and
90oC for 15, 30, 45, 60minutes to identify thermostability. At 30oC and 45oC temperature, spores
of A. niger isolates found to be thermostable. But at 60oC, 75oC, or 90oC treatment spores
become inactivated or there 6.0 logarithmic reduction in spore count was observed.
Thermostability of phytases was found at 60oC, 75oC, 90oC for 15, 30, 45, and 60
minutes treatments. Enzyme from A. niger PASN01 and PASN08 observed as thermostable at
60, 75 and 90oC. Phytases from PASN01 and PASN08 showed 160.55±42.96 and 00±.00
FTU/mL decreased in activity after 45 minutes of treatment at 60oC temperature, respectively.
PASN01 phytase displayed 163.88±23.35, 172.77±7.52 and 171.66±7.26 FTU/mL decreased in
activity after 60minutes treatment at 60, 75 and 90oC. In case of PASN08 phytase at 60, 75 and
90oC temperature after 60minutes treatment, 13.33±10.41, 16.66±6.00 and 23.88±41.37 FTU/mL
decreased in activities were observed, respectively. PASN08 phytase observed more
thermostable than other phytases of A. niger isolates. Enzyme can bear pelleting and pre
pelleting temperatures. Enzyme from PASN08 also observed stable during storage at room
temperature.
Conclusion:
A. niger PASN08 spores inactivated or killed and phytase observed stable at 60oC
temperature, after 60mins treatment. Temperature 60oC may be used industrially for cost
effective thermostable phytase production from indigenous A. niger isolate PASN08. Availability: Items available for loan: UVAS Library [Call number: 2475-T] (1).

Publisher: 2016Dissertation note: Colostrum is milk obtained from mammals secreted after parturition. It differs from normal milk
as it contains numerous bioactive components which include growth factors, lacto-peroxidase,
lacto-ferrin, Igs, lysozyme, nucleosides, vitamins, oligosaccharides and peptides, which are health
promoters. Cottage cheese is an excellent source of cyanocobalamin, riboflavin and pyridoxine.
Using colostrum for making cottage cheese can give opportunities to increase cottage cheese
quality which may be more functional, healthier with high yield. Preservation of colostrum in the
form of cottage cheese can be supportive for obtaining functional cheese with enhanced shelf life.
Nili Ravi Buffalo postpartum milk was used for the production of Cottage cheese. While the
control was prepared from Nili-Ravi buffalo normal milk. Milk was pasteurized at 63 °C for
around 30 minutes in batch pasteurizer. Then the milk temperature was brought down at 37°C for
inoculation with the mother cultures mentioned above at 2% level. Three replicates for each
treatment was prepared. Incubation continued for 30 minutes at 42°C. Then 1.7 ml CaCl2 was
added and after 10 minutes 1.7 ml of rennet solution was added in cheese milk and left for another
40 minutes for coagulation. Then the curds was cut into 1cm3 and healed for 10 minutes. The
temperature is raised to 55°C for cooking for 30 minutes. Then whey was drained for 24 hrs. The
curd was pressed and shaped into mold and then wrapped in aluminum foil and stored at 4°C for
7 days for further analysis. The physicochemical analysis such as pH, Acidity%, Fat %, TS %, Ash
%, Chlorides %, Casein %, Protein% and Lactose% of Colostrum and Colostrum based Cottage
cheese with respect to control was carried out by standard methods as described in AOAC. The
data thus collected were analyzed through one way analysis of variance under Completely

Randomized Design (CRD). Means were compared through Duncan’s Multiple Range (DMR)
Test (SAS 9.1 Statistical Software).
Physicochemical analysis of Colostrum showed that pH is in the increasing trend with the increase
of age of milk and results showed that Colostrum pH values lower than milk values and were
related to the high proteins content that is usually revealed in colostrum obtained 2-3 days after
birth. While the trend of titratable acidity %, fat %, chlorides %, specific gravity, ash %, Total
solids %, Total protein % and casein % is decreasing with an increase in the age (Days) of
postpartum milk.
Physicochemical analysis of Colostrum Cottage Cheese showed that the trend of pH of colostrum
cottage cheese remained constant with the increase of age. The trend of lactose% and ash % is
increasing with an increase in the age of postpartum milk. While the trend of titratable acidity %,
fat %, chloride%, total solids %, total protein % and casein % of cottage cheese is decreasing with
an increase in the age (days) of postpartum milk.
Microbiological analysis of Cottage cheese was examined. Coliforms remained absent (<10 cfu/g)
during whole storage time. Total Plate Count (TPC) was not significantly different throughout the
storage period as it renders growth if there are hygiene and proper storage conditions available.
Sensory evaluation was be carried out using criteria of appearance, taste, color, flavor and whole
acceptability on a hedonic scale of nine points. T0, T3, T4 and T5 showed cheese like aroma, T1
showed yoghurt like aroma while T2 showed cheese like/ slight acidic aroma after 7 days of storage
period. T0 and T5 showed whitish appearance, T1 showed light yellow appearance, T2 showed
slight creamy like color after 7 days of storage period while T3 and T4 showed off white
appearance after 7 days of storage period. T0, T4 and T5 showed light acidic flavor, T1 and T2

showed slight saltish / most bitterness in taste while T3 showed acidic taste after 7 days of storage
period. T0 and T5showed granular texture with no creaminess, T1 showed soft yoghurt like
texture, T2 showed meaty / hard texture while T3 and T4 showed harder toffee like texture after 7
days of storage period.
Colostrum is the most proteinaceous food as compared to milk and improves the nutritional aspects
as well as quality and yield of the products. So Cottage cheese made from Colostrum is more
nutritious, functional with probiotic characters as well as enhanced physico-chemical properties
with high yield. Availability: Items available for loan: UVAS Library [Call number: 2473-T] (1).

Publisher: 2016Dissertation note: Mutton is also very extensively used food and sources of mutton are only sheep and goat.
Sheep have a great genetic potential to fulfill the increasing demand of mutton in our country.
Body conformation and features are very important traits in milch, meat and wool animals. In
developing countries, record keeping is at initial level and the records about pedigree and progeny
of individuals are insufficient and do not provide the estimation about genetic parameters.
Therefore, phenotypic information are necessary for the explanation of relationship among linear
type traits and selection is based on these traits. Principal component analysis technique has been
used to identify the body size, body shape, head size and over all body conformation in Zulu Sheep.
Animal conformation and genetic parameters can be measured by using the technique of
phenotypic characterization.
Data on morphometric traits of Thalli sheep were collected from “Small Ruminant
Research and Development Centre, Rakh Khairewala, District Layyah, Punjab, Pakistan” and
Livestock Experiment Station, Rakh Ghulaman, District Bhakkar, Punjab, Pakistan. Different
phenotypic parameters and twenty one (21) morphometric traits were measured on animals of
Thalli sheep. The traits measured were birth weight, body weight, heart girth, body length, withers
height, head length, head width, ear length, ear width, neck length, neck width, barrel depth, sacral
pelvic width, rump length, rump width, tail length, testes length, testes width, scrotal diameter, teat
length and teat diameter. Different phenotypic characters was recorded as body color, body shape,
eye color, head color, fore head color, face color, face structure, chin color, ear color, ear nature,
appendages color, nostril structure, muzzle structure, neck structure, tail color and tail switch.
Summary

Weighing balance (digital) was used for determination of body weight and a flexible
measuring tape (tailor tape) was used to record the different body measurements. To avoid
variations among individuals, measurements were taken by the same person. Animals of different
age groups were reared at these research stations. Animals were divided into different groups (A,
B, C, D, E, F, G, H and I) according to their age as 0-3, 4-6, 7-9, 10-12, 13-15, 16-18, 19-21, 22-
24 and above 24 months. Each group was further divided into two sub-groups of males and females
animals. Normality of data were checked against all animals (overall group and separate groups)
and all animals were fallen in ±3SD but two outliers had been removed. Data on morphometric
traits were analyzed statistically for mean, range, coefficient of variation and standard error.
Pearson’s coefficient of correlation among different biometric traits was estimated and data were
generated for principal component analysis (PCA) from the correlation matrix. Regression
equations were developed for the estimation of body weight.
Descriptive statistics (mean, range, standard deviation and coefficient of variation) of body
measurements of overall female were showed coefficient of variations of overall female animals
of Thalli sheep for mostly variables were ranged from 10-20% and coefficient of variations of birth
weight and body weight were 22.38% and 25.75% respectively. Coefficient of variations of male
animals of Thalli sheep for linear body measurements were ranged 08-25% and tail length had
high coefficient of variations as 26.89%. Male animals of all age groups are heavier than females.
Correlation coefficients of morphometric traits of overall females and males of Thalli sheep
were highly positive and significant (P≤0.01) among withers height, body length, heart girth, head
length, head width, ear length, neck length, neck width, rump length, rump width, barrel depth,
sacral pelvic width and body weight. Withers height, heart girth and body length were observed to
be significantly correlated with each other as well as with live body weight of all age groups.
Summary

For overall female animals, two principal components were extracted with eigenvalues
9.005 and 1.558 and 56.279% and 9.740% variances for PC1 and PC2 respectively and their
cumulative variance was 66.020%. For overall male animals, three principal components were
extracted with eigenvalues greater than 1 and PC1 showed high variance 57.516% and PC2 and
PC3 had variances as 12.184% and 7.022% respectively and their cumulative was components
76.721%. In all age groups which has been studied, withers height, body length and heart girth
have high values in commonalities as well as in component matrix. PC1, PC2 and PC3 showed
maximum variations in almost all age group studied.
Regression equations developed to estimate of live weight of all age groups were indicated
that almost all equations had variables withers height, body length and heart girth.
Conclusion:
From findings of present study, it was concluded that body measurements (Withers height,
body length and heart girth) had high correlations with each other and with body weight in almost
all age groups. Principal component analysis of morphometric traits was showed that most of
variation explained by PC1 and in some groups, PC2 and PC3 had also more effects.
Commonalities were higher which showed that all the variables were important but PC1 had high
values for withers height, body length and heart girth and maximum variance. This indicated that
morphometric traits are very important for selection of genetically elite animals. Morphometric
traits can be used to estimate the body weight in the field conditions, where weighing balance is
not usually available. However, further research is needed to investigate the relationship among
different morphometric traits in other breeds of goats, sheep and other livestock breeds like cattle,
buffalo, camel and horse of the country. Availability: Items available for loan: UVAS Library [Call number: 2471-T] (1).

Publisher: 2014Dissertation note: Back ground: Among various factors that are affecting buffalo productivity, heat stress is challenge for the dairy farmers of Pakistan since the geographical location of Pakistan is sub-tropic as it is situated 23.6 degree above the line of equator between Tropic of Cancer and Tropic of Capricorn and summer season prevail for long duration with high ambient temperature and relative humidity. Information on production potential of mature Nili-Ravi buffalo against hot-dry and hot-humid season and its adaptability to the sub-tropical conditions of central Punjab has not been documented before. In this regard, study is designed to understand the relationships of environmental stress with physiological, behavioral and production responses in Nili-Ravi buffaloes under different housing and cooling conditions.
Hypothesis: Developing and implementing housing and cooling systems to mitigate heat stress may decrease this effect but must be cost effective. To test these hypotheses, the proposed study was carried out at Buffalo Research Institute (BRI).
Methodology: Four experiments were conducted to evaluate the physiological, productive, serum biochemical and behavioral profile of mature Nili Ravi buffaloes under subtropical conditions, at BRI (Buffalo Research Institute), Pattoki. Experiments were conducted during proposed duration of March-April; May-June; July-August and September-October on various physiological and productive parameters. Lactating Nili Ravi buffaloes (n=20) were divided in to four groups with five animals in each group. Group A buffaloes were kept under roof shades

only (control). Group B was supplemented with yeast powder under roof shade; C group buffaloes were raised under ceiling fans and group D was treated with ceiling fans and showers.
During all summer periods, fans with showers (D) showed highest milk production followed by fans only (C), then control A and B have been similar for most of times. However, in early summer (March-April), the additional cost of supplement feed and cooling strategies was higher than revenue generated from increased milk. Cost per liter of milk produced was higher and thus marginal revenue was lower than expected. Whereas, shaded group A showed comparatively less milk production which was offset by low production cost as there were no additional costs of supplementing feed or cooling strategies.
In all other periods of mid-summer (hot-dry: May-June and hot-humid: July-August) and late summer (July-August), higher milk production was noticed in group D followed by group C despite additional costs of cooling strategies. Lower cost/ liter of milk were noticed as well as high marginal revenue. During these periods, fans were noticed as more effective strategy to alleviate thermal load compare to supplemental feed as cost per liter was high and marginal revenue was less in group B. Looks like feed additive may only be applicable in early summer compare to fans group but shaded group A had best performance in terms of cost per liter and revenue. Group D was found best followed by C in terms of lower cost per liter and high marginal revenue in mid and late summer.
Statistical Analysis: The recorded data was subjected to statistical analysis by using analysis of variance technique (ANOVA) under completely randomized design (CRD). The difference of means among treatment groups were determined by using Duncan Multiple Range Test (DMRT;

Steel et al., 1997) for the interpretation of results and portraying conclusions with the help of statistical software (Statistical packages for social sciences; SPSS).
Conclusion: However, it is noted that during March and April control group buffaloes performed better economically but they had lower production and higher physiological responses. Improved performance and health of animals under fans with or without showers did not produce enough marginal income to pay for the additional costs. Shaded group A showed comparatively less milk production which was offset by low production cost as there were no additional costs of supplementing feed or cooling strategies. Therefore, small scale farmers may use shade only for their buffaloes during early summer only but progressive farmers better go for shower and fans strategy since early summer as this approach works best throughout other periods of summer season. Since, the group D was found best followed by C in terms of lower cost per liter and high marginal revenue therefore, fans with showers would be a quite useful technique for progressive farmers and also necessary from animal’s health point of view. Also, small scale farmers may use fans to avoid drastic decrease in milk production and take maximum achievable measures according to their affordability during mid and later summer.

Publisher: 2015Dissertation note: Fasciolosis is the disease of sheep, goats, cattle and other ruminants. Human and equines are unusual hosts in which instead of liver the flukes may found in lungs or under the skin. Transmission depends on an intermediate host lymnae snail. Animal ingest metacercaria, the worm migrates to the liver where it causes extensive damage and mature worm lives in bile duct. The disease occurs as an acute, sub-acute or chronic infection. Chronic Fasciolosis characterized by anemia, hypoalbuminaemia, emaciation, submandibular edema and loss of condition. Clinical disease is well known but sub clinical infections are often unnoticed, leading to marked economic losses, reduced milk yield, weight loss, reduced fertility and immunity, consequently leading to significant economic losses. Fasciolosis has recently been recognized as an emerging zoonotic disease. Infections in human may be asymptomatic but sometimes nonspecific pain in abdomen, anorexia, dyspepsia and vomiting may occur. Pain in right hypochondrium, epigastrium and jaundice occurs in chronic phase. Sometimes ectopic migration of worm causes abscesses in many organs.
The present study investigates the prevalence of Fasciolosis in sheep and goats at different geographic locations on the basis of altitudes in Azad Jammu and Kashmir. 4662 (sheep n=2242; goat n=2420) fresh fecal samples from sheep and goats were collected from three village/towns each of Mirpur, Poonch and Muzaffarabad Divisions. Stool samples were collected from 566 pastoral families of AJK to determine the zoonotic potential of the disease. Prevalence of the disease was calculated on the basis of centrifugal floatation and sedimentation techniques.
The intensity of infection was calculated using the McMaster egg counting technique. The risk factors of the disease studied included altitude, season, sex, age, and effect of deworming and flock size on the rate of prevalence. An overall prevalence was recorded as

17.88%. Prevalence of Fasciolosis in sheep revealed 26.49% and that of goats 9.91%. The data was analyzed using Chi-square test which revealed a significant difference (P<0.05) in the prevalence of the disease in sheep and goats. The overall prevalence rate in both species was recorded as15.09% at altitude <3000 feet, 25.00% at 3000-6000 and 15.74% at >6000. The highest prevalence was recorded at an altitude 3000-6000 feet. Chi- square values showed significant difference (P<0.05) among three different altitudes. The altitude of 3000-6000ft showed a significantly higher (P<0.05) prevalence of Fasciolosis in sheep and goats. The overall prevalence showed 13.93% rates in spring and 21.77% in autumn. Chi-square values showed a significant difference (P<0.05) in the prevalence of the disease, higher in autumn than Spring. Sex wise prevalence showed 16.67% in male and 18.59% in female animals. The data showed no significant difference (P>0.05) in Chi-square analysis. The prevalence of the disease in the age group below 1 year was 04.40%, 1-4 years revealed 17.73% disease and 36.18% in >4 year. The data showed significantly different (P<0.05) rates in all age groups. Highest prevalence was recorded in sheep and goats above 4 year of age and lowest in those below 1 year. The prevalence in animals with no recent history of deworming was recorded 23.22%. The data showed 15.37% disease in small flocks of sheep and goats <30 as compared to 18.72% in large flocks >30. Chi-square showed a significantly higher (P<0.05) prevalence of the disease in large flocks.
Generalized Linear Model (GLM) was used to evaluate the contribution of risk factors (epidemiological factors) to the variations in the prevalence of Fasciolosis in sheep and goats. All the epidemiological factors i.e. altitude, species, season, gender, age group, deworming and flock size were processed. The deworming appeared to be the most significant factor in the model contributing maximum variations in disease with highest Odds followed by age groups,

species, season, altitude, flock size and gender. The risk factors for the Fasciolosis in sheep and goats were found, lack of practice of deworming, age group >4 year, species sheep, season Autumn, altitude 3000-6000 and flock size >30. The 75% of the disease prevalence was due to above mentioned risk factors. The deworming, specie goat, age group <1 year, season Spring, altitude <3000, and flock size less than 30 were appeared to be the protective factors in the Generalized Linear Model.
The intensity of infection was analyzed through Factorial analysis for difference in species, altitude and season. The difference in eggs per gram of feces was found significantly different (P<0.05) in sheep and goats. The effect of season on egg per gram (EPG) of feces showed a higher mean values in sheep (191.49) and goats (219.72) in Autumn as compared to 158.04 and 180.61 in Spring. In both seasons the mean for goats was found higher than sheep. The effect was found significant (P<0.05), higher during Autumn. Factorial analysis of the data showed significant interaction (P<0.05) between species and altitude. The data showed mean values for sheep 174.04, 191.87 and 168.33 at altitude <3000, 3000-6000 and >6000 feet respectively. The mean values for goats were 232.22, 194.95 and 170.59. The data revealed higher mean for goats as compared to sheep on all three altitudes. Goats revealed significantly higher (P<0.05) number of EPG. POST HOC Tukeys test showed a non-significant difference in intensity of disease between <3000 and 3000-6000 feet, rest of the differences were significant (P<0.05).
The overall prevalence in pastoral communities of AJK was 0.88%. The samples were collected from male and female of 4 age groups <10 year, 11-20, 21-40 and >40. The prevalence in male was 0.76 and in female was 0.98%. The data showed that age groups below 20 year were

the susceptible groups in both sexes. The highest prevalence (2.25%) was found in female age group 11-20 year. Age groups above 20 year did not revealed any positive sample.
227 adult liver flukes were collected from livers of infected animals of different animal species (sheep, goats. cattle and buffaloes) and geographic locations for morphometric and molecular identification of the species of Fasciola. Flukes were identified on the basis of measurements of body length, body width, diameter of suckers, distance between oral and ventral sucker and distance between ventral sucker and posterior end of the body. The measurements of F. hepatica showed a body length range 13-34mm with an average length of 21.51mm whereas, F. gigantica ranged from 28-52mm with an average of 42.27mm. The average body lengths of F. hepatica below 3000ft was 21.9, at 3000-6000ft was 21.07 and above 6000 ft was 22.00mm and that of F. gigantica was 42.05 and 42.44mm at 3000 and 3000-6000 feet. The measurements of F. hepatica revealed an average body width of 10.05mm, average diameter of oral and ventral suckers of 0.74 and 1.28mm respectively and average distance between the two suckers of 1.34mm. The readings for F. gigantica were 9.46, 0.89, 1.55 and 1.72mm respectively. Average distance between ventral sucker and posterior end of the fluke in case of F. hepatica was 18.35mm at all three altitudes and host species of animals and it was 38.26mm in case of F. gigantica. The overall mean worm load was 13.56 worms per liver of animal with a range 5-26. The mean worm load of F. hepatica was 10.9 and that of F. gigantica 13.11. Mixed infections were noted at altitudes below 6000 ft. Infestation with F. gigantica was not found at altitudes above 6000ft and F. hepatica was encountered at all three altitudes. 51.98% of the recovered flukes were F. gigantica which showed the equal chances of infection with either species of Fasciola in AJK. The results revealed that F. hepatica was the fluke affecting animal population at altitude above 6000 ft and F. gigantica was the major fluke below

3000 ft. At altitudes between 3000-6000ft, 36.20% of flukes were F. hepatica while its prevalence was reduced to 17.30% below 3000 ft. Once the species of the liver flukes were identified morphologically they were subjected to molecular conformation through amplification of the genomic DNA of the two species through PCR using two sets of species specific primers. In the PCR based on primer set 1, a product of 391 bp was generated from the genomic DNA of Fasciola hepatica whereas no product was generated from the DNA of Fasciola gigantica. PCR based on primer set 2 amplified a 235-bp product from the DNA of Fasciola gigantica. The molecular identification in the present study showed that morphometric identification of the two species is valid and standard population of both species were found present at different geographic locations and species of the animals of the state of Azad Jammu and Kashmir except F. gigantica not found above 6000 feet altitude.
The ethno veterinary practices for Fasciolosis were documented through Participatory Rural Appraisal. A total of 173 respondents/key informants were interviewed during the study period in the study area. The majority of the traditional healers (n=33) elders of pastoral families (n=53) and sheep/goats owners (n=56) were above the age of 40 year.

Publisher: 2016Dissertation note: This six months study on semen morphology and effect of artificial insemination on hatchability in turkeys,Meleagrisgallopavo was conducted at Avian Conservation and Research Center, Department of Wildlife and Ecology, Ravi Campus, University of Veterinary and Animal Sciences, Lahore. Mature male (n = 3) and female (n = 24) birds were selected at random and were kept separately for two weeks. The female birds were divided into three groups, each group having eight females while the male birds were housed in separate cages. The tom in cage 1 was fed with poultry feed, while the toms in cage 2 and cage 3 were fed with corn and millet, respectively. All the cages were provided with separate drinking and feeding facilities.
For the collection of semen, male birds were conditioned and trained through abdominal massage. The testes of the male birds were massaged until the semen was collected using a rubber pipette and was transferred to collection vials. The mass mobility, concentration, color, morphology, volume and live-dead ratio of the collected semen were analyzed through microscope in Postgraduate Laboratory, Department of Wildlife and Ecology, Ravi Campus, University of Veterinary and Animal Sciences, Lahore and compared for test diets.
The laid eggs were collected from each cage and the weight of male and female birds, cage number and the weight of the egg was noted on the eggs and these eggs were transferred to storage cabinet. The eggs were then transferred to the incubators and the chick weight and hatchability percentage was recorded for natural and artificially inseminated birds.
After completion of the trial, one male and one female bird were manually eviscerated; the eviscerated carcassand sensory quality attributes, for meat sample for breast and thigh piece from male and female M. gallopavowere individually boiled and were presented to twenty semi-trained personnel for analysis of meat quality characteristics viz. meat color, juiciness, flavor, tenderness and overall acceptability.
Average semen volume for thirteen consecutive fortnights from the toms from cage 1 (fed with poultry feed) was 0.17±0.01 ml while semen volume for the toms in cage 2 (fed with corn) and cage 3(fed with millet) were recorded as 0.15±0.04 ml and 0.17±0.01 ml, respectively. Average live and dead ratio for the toms in cage 1 was 85.46±1.71while live and dead ratio for the toms in cage 2 and cage 3 were recorded as 85.15±3.05 and83.54±2.50, respectively. Average semen concentration for poultry feed, corn and millet fed toms was 6.62±1.33 (109cells/ml), 5.85±2.34 (109cells/ml)and 6.00±1.47 (109cells/ml), respectively.
Average mass motility in M. gallopavo fed with poultry, corn and millet feeds was 85.46±1.71 %, 85.15±3.05 % and 83.54±2.50 %, respectively. Average sperms without acrosome were19.23±1.83 %while acrosome defects due to hooked shaped acrosome, acrosome swelling and rounded acrosome for were recorded as 17.46±2.33 %,16.00±2.89% and 16.38±2.75 %, respectively.
Average bent head defects were 6.0±1.7 %, hooked shaped heads were 4.5±1.7 %, twin heads 4.8±1.9 %, swelled head sperms were 3.6±1.6 %, knotted head,5.6±1.2 %, larger head 5.0±1.8 % and short headed sperms were 4.8±1.4 %. Average bent mid piecedefects were 5.1±2.3 %, irregular mid piece 4.8±2.8 %, partially detached mid piece 5.0±2.5 %, swelled mid piece 5.5±1.9 %, mid piece swelled near neck region 5.0±2.4 %,knotted mid piece 4.4±2.3 % and spiral mid piece were observed 5.0±2.1 %.
Average double taildefects were recorded 4.31±2.25 %,coiled tail defects 4.00±1.73 %, knotted tail 4.77±2.20 %, bend tail 3.62±1.76 %, curled tail 4.85±2.19 %, detached tail 0.15±0.04 % and short tail defects were recorded 0.17±0.01 %.
Average hatchability from the eggs collected from naturally inseminated hens was 84.38±3.43 % while the same was recorded 89.69±3.01 % for the eggs laid by the artificially inseminated hens.
Growth parameters of male and female turkeys selected for the experiment were taken and compared. Statistically significant (p<0.05) variations in body weight, snood length, beak length, wing length, wingspan, body length, body girth, tail length, shank length, tarsus length were recorded between male and female Meleagrisgallopavo.
Positive correlation existed between body weight of the female with weight, length and width of the laid eggs. The weight of the eggs showed positively significant correlation with the length of the eggs.
The carcass characteristics viz. live body weight, thigh weight, leg piece weight, heart weight, liver weight, skull weight, gizzard weight, kidney weight, stomach weight, feather weight, lung weight, neck weight, wings weight, chest with wings weight, chest without wings weight were recorded heavier in male turkeys as compared to the females.
The chest and thigh pieces of male and female turkeys were analyzed for meat sensory quality attributes viz. color, flavour, juiciness, tenderness, oiliness and overall acceptability. Statistically significant (p<0.05) variations in color and overall acceptability in thigh and chest pieces were recorded for both the sexes.
It can be concluded from the present study that artificial insemination in turkeys is more fruitful than natural mating and influences hatchability of eggs.

Publisher: 2016Dissertation note: Sore throat or pharyngitis in childrenis mainly caused by group A (β-hemolytic) Streptococcus pyogenes. The bacterium transferred from infected person to susceptible one through coughing, sneezing and by direct contact. Irrational use of antibiotics to control sore throat infection results in development of antibiotics resistance. To overcome the problem of antibiotic resistance, various herbal extracts(Liquorice, ginger, cinnamon and red dates)are used which have known antimicrobial activity against these bacterial isolates.
In current study 70 throat swab samples were collected from Children Hospital, Lahore and processed to isolate and identify antibiotic resistant sore throat bacteria by swabbing on blood agar andTryptic soya agar.Initial identification was done using conventional biochemical tests and confirmation was done through API 20 Strep. Antibiotic resistance pattern in isolated bacteria was done by modified Kirby Bauer disc diffusionas per CLSI,2014 criteria.Extracts (Ethanolic, boiling and distilled water) of herbs (Liquorice, ginger, cinnamon, red dates and kalonji) was obtained and tested for antimicrobial activity against resistant isolates. Efficacy of the herbal extracts was evaluated through Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentrations. Ethanolic extracts of Liquorice, ginger, cinnamon and red dates have good antimicrobial activity against resistant sore throat bacterial isolates than boiling and distilled water extracts.
The present study demonstrated that S. pyogenes and Staphylococcus are major bacteria responsible for sore throat infection in children. These isolates have variety of different antibiotic resistance patterns. In order to minimize emergence of antibiotic resistant isolates, herbal extracts can be used.Ethanolic extracts of liquorice, ginger, cinnamon, red dates have good antibacterial activity as compared to kalonji. Statistical analysis showed that ethanolic extracts of Liquorice has a significant activity with ginger, cinnamon and red dates.The degree of antibacterial activity of plant extracts testedcan be graded in the following order: Liquorice> ginger>Cinnamon>red dates>kalonji. Itis estimated that by using natural products will reduce the resistance in microorganism.

Publisher: 2016Dissertation note: Enterococcus faecium is gram positive bacteria which are normal intestinal flora of warm blooded animals and humans beings. It is responsible for various types of diseases such as neonatal meningitis, endocarditis, urinary tract infections and intra-abdominal or pelvic wounds. Retail chicken could be a source of Enterococcus faecium. Irrational use of antibiotics in chicken rearing can lead to emergence of antibiotic resistant Enterococcus faecium. The chicken meat gets contaminated at the time of slaughtering and resistant bacteria may transfer to human beings through food chain.
In present study prevalence of E. faecium recovered from retail chicken meat samples collected from various areas of Lahore city was estimated. A total 43 chicken sample (leg or wing) were processed for isolation of E. faecium. Identification of E. faecium was made using standard culturing and biochemical reactions. Out of 43 samples, 30 samples (69%) were found positive for Enterococcus faecium. Antibiotics resistance profiling showed that the isolates were resistant to following antibiotics mentioned as below: Ampicillin (100%) >Tetracycline (73%) > Erythromycin (53%) > Ciprofloxacin (46%) > Chloramphenicol (40%) > Rifampicin and Vancomycin (36%) > Teicoplanin (33%) > Doxycycline (20%) > Fosfomycin (0%). From the study it is concluded that retail chicken is the carrier of antibiotic resistant Enterococcus faecium and could transfer resistance to humans. Efforts should be made to use antibiotics wisely and hygienic practices should be followed during slaughtering and processing of chicken meat to avoid bacterial spread from animal source to human beings.

Publisher: 2016Dissertation note: PPR is one of the most acute viral disease of sheep, goats, deer and other similar animals. This disease is caused by Morbillivirus which belongs to familyParamyxoviridae. In this disease oculo-nasal discharge, stomatitis, diarrhea, high temperature, and pneumonia is common sign.along with foul breath.Goat pox virus (GPV) disease is extremely transmissible described by temperature, falling down and different stages of pox lesion development such as, vesicles, scars, pustules, erythema and papules, all over the body.
This study was aimed to evaluate the monovalent lyophilized PPRV and GPV vaccine with bivalent PPRV and GPV vaccines. Moreover effect of amount of immunogen of the vaccines, and nature of adjuvant used in the vaccine on antibody response of goats was also evaluated.Seven types of vaccines PPR (FD), GPV (FD),PPR+GPV (FD), PPR+GPV(gel 102.5), PPR+GPV(gel 103.5), PPR+GPV(gel 104.5) and PPR+GPV(oil) were prepared. All vaccines other than gel based contained 103.5 immunogen level. Each vaccine was inoculated to each of the six goats of the respective group. Blood was collected at 21, 42 and 63 dayspost vaccination. The antibody response of goats was measured with CFT.
There was non-significant difference between the anti-PPR antibodies induced by either monovalent or bivalent vaccines. Similarly goat Pox vaccines also produced non-significant difference in both monovalent and bivalent form. Antibody response was directly proportional to the amount of specific immunogen in the vaccine. There was non-significance effect of gel or oil in the vaccine as an adjuvant on the antibody response of goats to the vaccine.

Publisher: 2016Dissertation note: Enterococcus faecium is an enteric, gram positive and lactic acid bacteria which belongs to genus enterococcus and inhabit the intestinal tract of human, fish and other warm blooded animals. Due to irrational use of antibiotics in human and veterinary sector, antibiotic resistance has been developed in commensal bacteria including Enterococcal species. These resistant bacteria are released in environment through human and animal waste and transfer resistant genes to susceptible bacteria present in wetlands making them antibiotic resistant. E. faecium is considered to be involved in transmission of resistance genes, present on mobile genetic elements through conjugation to other bacteria. The resistant bacteria can be transferred to human through food chain. The present study was designed to evaluate the prevalence of E. faecium recovered from retail fish samples collected from various areas of Lahore city. Antibiotic resistance profiling of the isolates against commonly used antibiotics was also determined.
In current study 65 fish samples (intestinal swabs) were processed for isolation of E. faecium through standard culturing and biochemical reactions. Out of 65 swab samples, 30 samples (47.69%) were found positive for Enterococcus faecium. Antibiotics resistance profiling showed that the isolates were resistant to antibiotics mentioned as below: Ampicillin (100%) > erythromycin (56.6%) > rifampicin (53.3%) > Chloramphenicol (30%), ciprofloxacin (30%) > tetracycline (20%), vancomycin (20%) > Teicoplanin (13.3%) > Doxycyclin (6.6%) > Fosfomycin (0%). E. faecium isolates showed resistant to at least 2 or 3 antibiotics of different group. In conclusion it is observed that retail fish is the carrier of antibiotic resistant Enterococcus faecium and

could transfer resistant genes to wetlands and other aquaculture from where it could be transferred to human body. Efforts should be made to use antibiotics wisely and hygienic practices should be followed during slaughtering and processing of fish meat to avoid bacterial spread from animal source to human beings.

Publisher: 2016Dissertation note: Improvement of post-thaw quality of Donkey (Equus asinus) semen is essential to augment the in-vivo and in-vitro fertilization rate and to be used for mule production. By the help of cryopreservation sperm cells can be stored for the long time but it causes lethal sub-lethal damage to the sperm. In most species including Donkey and horses sperm cryosurvival rates are not optimal because of its plasma membrane composition. One of the major cryopreservation damage is produced by Reactive oxygen species (ROS) generating oxidative stress caused by ROS are important for normal sperm function but in normal concentration. When they are produced in more quantity they cause damage to Acrosome, DNA and plasma membrane. . Alpha lipoic acid is a non-vitamin coenzyme that helps in significant metabolic and antioxidant functions in the body. Alpha lipoic acid has been reported to have extra functions by which they are able to synthesize vitamin C from its reduced form in the presence of glutathione. It is matchless among biological antioxidants, because it is equally lipid and water soluble. This allows it to nullify free radicals almost everywhere in the body, inside as well as outside the cells. Therefore, the objective of present study was to determine the effect alpha lipoic acid on post thaw quality of jack semen. Alpha lipoic acid scavenge on reactive oxygen species formed in semen during the process of cryopreservation, so it maintained good semen quality during post thaw. Two adult donkeys (Equus asinus) (4-6 years old) kept at animal shed Ravi campus pattoki were used in the study. All the animals were managed under optimal condition of feeding and management. Donkeys were offered green fodder with ad libitum supply of water. Semen collection was done twice a week (one ejaculate/collection) using an equine artificial vagina having temperature of 45-50 ºC. Five collection from each donkey were done (n=10). Ejaculates were filtered with muslin cloth to remove gel. Semen volume was measured by collecting semen in a graduated collection tube after

filtration and the sperm concentration was measured by using a phase contrast microscope (40 x, Nikon) and was scored with a coverslip and then immediately was kept in water bath having 37 ºC temperature after collection until evaluation and processing. Semen quality parameters like volume, concentration and motility were recorded. After initial evaluation, semen samples were extended with centrifugation extender in 1:1 and seminal plasma was removed after centrifugation. Supernatant was removed so that seminal plasma up to 20% will remain with sperm pellet and was maintained at 37 ºC temperature in water bath and was extended with extender having different concentrations of Alpha lipoic acid (0mM, 0.5mM, 1mM, 1.5mM, and 2mM) and cooled for 2 hours and then equilibrated for 2 hrs at 4oC. Then, French semen straws of 0.5ml capacity were filled with semen (100x106/straw). All semen straws were arranged on a rack and then placed at 4cm height above liquid nitrogen vapors for 10 minutes. Finally semen straws was put in liquid nitrogen, Total five replicates per donkey were performed. Now post thaw quality was checked in which various tests were performed, like %age motility, Acridine orange assay for DNA integrity, HOST for plasma membrane integrity, FITC-PNA/PI for viability and acrosomal integrity. It was expected that Alpha lipoic acid shown positive effect on post thaw quality of donkey semen, in the meaning of increased percentage motility, Less DNA damage during cryopreservation and incubation, Increased acrosomal and plasma membrane integrity. So alpha lipoic acid shown positive effect by counter acting on ROS during cryopreservation by reducing melondialdehyde production as indicated by MDA test carried out in this study. Results acquired from this study shown that an increase in sperm motility, plasma membrane integrity, DNA integrity, Acrosomal integrity, viability and survival was caused by ALA competences in energy production and anti-oxidant properties, when used at the concentration of 1.5mM. In summary, based on the results

of our study, it can be concluded that an optimal concentration (1.5mM) of ALA improved PMI, sperm motility and viability, minimize DNA damage and improved sperm survival. Availability: Items available for loan: UVAS Library [Call number: 2494-T] (1).
