Publisher: 2015Dissertation note: Parthenogenesis is a phenomenon in which the development of oocyte oocur without fusion of male gamete. During fertilization spermatozoa trigger intracellular Ca+2 oscllation in M-II stage oocyte which initiates the embryonic development. The rises of intracellular calcium (Ca2+) ions is the basic step for the parthenogenesis. During parthenogenetic activation calcium channel open from endoplasmic reticulnum or depletion of calcium store and facilitate the calcium (Ca2+) from extracellular environment. Parthenogenetic technique is applied in cloning and production of embryonic stem cell lines for used to treat different diseases. Many scientists used different chemicals agents for artificial activation such as strontium, Ionomycin and Ethanol. Strontium chloride has been used widely for parthenogenetic activation of mouse oocyte, but its result to blastocyst development is poor. The objective of present study is to improve parthenogenetic activation and embryo development by combination of Ionomycin with strontium. Hypothesis of my study was Addition of Ionomycin in Strontium based activation protocol improves embryonic development.
The present study was conducted in embryology lab of department theriogenology, university of veterinary and animal sciences, Lahore.Six to eigth week old female mice (n=100) were super ovulated with intra-peritoneal injections of eCG (5iu) followed by hCG injection (5iu) at 48 hrs interval. 14 hrs post hCG, the cumulus oocyte complexes were collected from oviduct of the mice. In experiment 1, the oocytes were activated by using Ionomycin with concentration of 5, 10 and 15 µmol/l for 5 and 10 followed by this activation with strontium chloride (10mmol/l). In experiment: 2, The oocytes were activated by activation medium having strontium (10 mM/l) and Ionomycin (5, 10 or 15 µmol/l) in combination. CZB medium were used for oocyte cultured in CO2 incubator of 5% CO2 at 37°C. Number of activated oocytes were analyzed by cleavage rate to blastocyst stage. In-vitro developmental potential of the activated oocytes were assessed by blastocyst. In experiment: 3, Zygotes were collected 18 h post-hCG and treated with the optimum concentration to check the toxicity effects on embryo development.
In experiment 1, There were insignificant results observed on the bases of cleavage rate in each groups and time of activation as compared to control group. The tendency of morula and blastocysts formation rate was higher (p<0.05) in the 15µM for 10 min activation time as compared to other treatment groups and control group. In experiment 2, The tendency of cleavage rate was significantly higher in the 10 µM and 15µM groups as compared to other treatment group. The blastocyst formation rate was no statistically difference in all treatment and control group. While the toxicity experiment, there was no toxic effect of Ionomycin with Strontium Chloride.
In conclusion, there was higher cleavage rate, 4 cells, morula and blastocyst formation rate in 15µM concentration of Ionomycin for 10 min with Strontium Chloride, there was no toxic effect of Ionomycin with Strontium Chloride on embryos and Ionomycin improved the activation rate and embryo development in combination with strontium chloride.

Publisher: 2015Dissertation note: Freezing and thawing of semen leads to production of reactive oxygen species (ROS)
due to plasma membrane lipid peroxidation. Because of this semen quality can be
compromised. To overcome this problem, antioxidants have been used in cryopreservation
medium. Glutathione and cysteine have thiol groups which penetrate into the cell and protect
it from oxidative stress. In this study, effect of different concentrations of cysteine and
glutathione on post thaw quality of Sahiwal bull spermatozoa was determined.
Semen was collected with artificial vagina from five mature regular donor Sahiwal
bulls kept at the Semen Production Unit Qadirabad, Sahiwal. Semen samples possessing
>60% motility and >500x10
6
sperm/ml were included in study. After collection, semen
samples from five bulls were pooled, divided into seven equal aliquots and kept at 37 ºC in
water bath. After that dilution was done with Tris citric egg yolk extender having different
concentrations of cysteine and glutathione as Con (0.0 mM), C1 (1.0 mM cystein), G1 (1.0
mM glutathione), CG0.5/1(0.5 mM Cysteine+1.0 mM glutathione), CG1/0.5 (1.0 mM
cysteine+0.5 mM Glutathione), CG0.5/0.5 (0.5 mM cysteine+0.5 mM glutathione) and
CG1/1 (1.0 mM cysteine+1.0 mM glutathione). Diluted samples were cooled to 4ºC in two
hours and equilibrated for 4 hours at 4
o
C. After that they were packaged into 0.5 ml French
semen straws (20x10
6
sperm/straw). All semen straws were placed 4cm above liquid nitrogen
surface in vapors for 10 minutes. Then, semen straws were plunged into liquid nitrogen for
freezing and stored until post thaw analysis. The experiment was repeated for five times
(replicates = 5). Four semen straws/treatment were thawed for 30 seconds in water bath at
37ºC and evaluated for visual motility, plasma membrane integrity (PMI), acrosome integrity,
mitochondrial trans membrane potential and CASA motility parameters and kinematics.

CASA results showed that CG1/1 had significantly higher motility as compared to the
control. But the percentage of progressive spermatozoa was significantly higher in
CG0.5/0.5. VSL of group CG0.5/0.5 was significantly higher (53.33±2.90 %) as compared to
Con (45.10±0.50 %). However, VSL, VCL, ALH and BCF did not vary significantly among
groups. STR and LIN of group CG0.5/0.5 were significantly higher as compared to the
control group.
43
Summary
In conclusion, addition of cysteine and glutathione in tris citric egg yolk extender
improved the post thaw quality of Sahiwal bull spermatozoa. In case of additive effect of
cysteine and glutathione, CG0.5/0.5 showed higher plasma membrane integrity, acrosome
integrity, mitochondrial transmembrane potential, progressive and rapid spermatozoa as
compared to CG0.5/1, CG1/0.5 and CG1/1.

Publisher: 2015Dissertation note: Presently, buffalo farmers are dissatisfied with fertility rates of the frozen semen used in the field and tend to use bulls. This study was designed to develop a suitable semen extender for cryopreservation of Nili Ravi buffalo semen that can improve conception rate in buffaloes.
Experiment-I, an attempt was made to develop semen extender with optimal osmotic pressure for buffalo semen using tris citric acid (TCAE), skim milk (SME) and coconut water (CWE) extenders (each extender have 260, 270, 280, 290 and 300 mOsm/kg osmotic pressure levels). In Experiment-II, best extender (TCAE: 300 mOsm/kg) of experiment-I was tried to improve post thaw spermatozoa characteristics by supplementing antioxidants [0.0, 1.75, 2.0 and 2.25 mM butylated hydroxy toluene (BHT) and 0.0, 2.0, 5.0 and 8.0 mM L-cysteine]. Post thaw spermatozoa motility, viability, plasma membrane integrity (PMI), DNA damage rate and lipid peroxidation were assessed in first two experiments. In Experiment-III, pregnancy rate assessment of extended semen was carried out by using Trial extender (best of experiment II) or Control extender of Semen Production Unit (SPU), Qadirabad, Pakistan (50 inseminations of each extender).
Higher spermatozoa motility at ≥ 270 mOsm/kg was noted in TCAE than both SME and CWE could be due to less intracellular ice formation in zwitterions extender. Higher spermatozoa viability in TCAE and CWE compared to SME may be attributed to extender effectiveness. Higher acrosomal integrity rate at 300 mOsm/kg in TCAE and SME may be because of less intracellular ice formation in isotonic extenders. At 290 mOsm/kg, higher spermatozoa PMI in SME and lesser DNA damage in three extenders might be due to lesser intracellular ice formation at cryopreservation. Decreased spermatozoa DNA damage in SME might be due to the presence of natural antioxidants i.e., casein. Higher lipid peroxidation in CWE than TCAE and SME may be due to presence of natural antioxidants (in SME) and higher cell dehydration potential of TCAE.
Higher spermatozoa motility recorded at 2.0 mM BHT compared to other BHT groups including DMSO might be due to fact that BHT protects spermatozoa mitochondria by reducing oxidative stress. Lower spermatozoa viability, PMI rates and higher DNA damage at 2.25 mM of BHT may be due to BHT toxic effects. Lower lipid peroxidation in BHT treated groups compared to DMSO and BHT control groups might be related to BHT strong antioxidant properties. L-cysteine caused higher spermatozoa DNA damage at highest level (i.e., 8 mM) that could also be due to antioxidant’s toxic effect.
Pregnancy rate 18 % higher was noted in Trial than Control semen extender; however no significant difference have been noted that might be due to less no of inseminations.
In conclusion, TCA extender (300 mOsm/kg) having BHT (2.0 mM) improved post thaw semen quality and yielded numerically better pregnancy rates. Results of study indicated that osmotic stress damaged the spermatozoa internal structures more severely than injury to plasma membrane.

Assessment Of Microbial Load, Protease Activity And Aflatoxin M1 In Raw And Uht Milk Procured From Local Markets Of Lahore
by Sadaf Almas (2007-VA-250) | Dr. Imran Altaf | Dr. Ali Ahmad Sheikh | Dr. Muhammad Nasir.
Material type: ; Literary form:

Publisher: 2015Dissertation note: Pakistan is among the largest milk producing countries. The requirement of milk is
increasing day by day. It has rapidly increasing demand and competition in national and
international markets. Milk consumers in Pakistan often face low-quality, lack of hygiene and
absence of cold chains as primary contributors to this low quality. Milk and dairy products also
become contaminated during manufacturing and packaging processes. The consumption of low
quality milk may cause milk borne diseases. Not only the bacteria but the presence of their
enzymes also can cause deterioration of the milk quality. The heat stable enzymes can cause the
spoilage of commercial UHT products without presence of any viable count. Aflatoxin (M1) is
metabolite of AFB1 in milk. It causes chronic diseases and immunosuppression in children. It is
found carcinogenic and cytotoxic in nature.
In this project microbial load, free amino acid estimation to predict any protease activity
and Aflatoxin M1 were studied in both UHT and Raw milk samples (n=15) procured from local
markets of Lahore. Three UHT brands A, B and C were purchased. The UHT milk was studied
for microbial growth and protease activity at purchase and at expiry of the products. The
microbial load was evaluated by testing of milk for Total viable count, Coliforms, Yeast and
Molds, Anaerobic Clostridia and Bacillus cereus in both raw and UHT milk. Protease activity
was estimated by assessing the free amino acid by using ninhydrin assay while the Aflatoxin M1
was detected through High performance liquid chromatography.
SUMMARY
80
CONCLUSION:
It was found that the locally available raw milk quality was poor for consumption and dairy
processing for safe and stable milk products. UHT milk quality was found better with low
microbial load. Protease activity with reference to free amino acid was detected in raw milk
which is indication of the poor milk storage conditions, cold chain maintenance and
unavailability of fresh milk. Protease activity was also found in UHT milk and an increase in free
amino acid which could be due to heat stable proteases active during shelf life of the milk
brands. Aflatoxin M1 was found in majority of raw milk sample which showed the poor animal
feed storage and monitoring system. Aflatoxin M1 was also found in some samples of UHT
brands with high concentration which depicted that AFM1 was heat stable and it retained in the
commercial UHT products as well. Availability: Items available for loan: UVAS Library [Call number: 2354-T] (1).

Publisher: 2015Dissertation note: Poultry industry is the most effective and economical source of animal protein in shortest possible time, but still it is unable to narrow down the animal protein supply and demand gap because of increasing future demands. Roundworms can cause a reduction in growth rate and damage to the intestinal mucosa, leading to blood loss and secondary infection. Heavily infected chickens may show symptoms of weight loss, droopiness, and diarrhea. Economic losses are usually associated with ascarid, Heterakis, and Capillaria, infections because of treatment cost, as well as the reduction in feed efficiency and weight gain as well as drop in egg production.
Fecal samples were collected from poultry birds in different production systems , in and around district Muzaffar Garh and samples were examined by using the direct smear method, flotation technique and simple sedimentation technique. Adult worms load were examined by necropsy of dead birds fortnightly. Post mortem of dead birds during study was examined for presence of nematodes in gastro intestinal tract fortnightly from each enrolled shed in the study. The samples of adult worm found were collected for identification.
During the present study four species of nematodes were identified. Ascardia galli was recovered from the small intestine, Heterakis gallinae and Subulura brumpti from the caecae . The most common gastrointestinal nematode was Ascaridia galli followed by Subulura brumpti and Heterakis gallinae. The present study has indicated that good husbandry techniques and regular deworming practices reflect markedly on the incidence and worm – burden of infected chickens Availability: No items available

Publisher: 2015Dissertation note: Retinoblastoma is a neonatal intraocular tumor caused by biallelic inactivation of RB1 gene. Rb
patients and asymptomatic carriers undergo a series of clinical tests for diagnosis and tumor
treatment. These clinical examinations prove to be expensive and time consuming. On the other
hand if the proband’s RB1 gene mutation status is determined by genetic testing, it can prove as
more significant and cost effective diagnostic methods. Secondly, only those asymptomatic or at
risk carriers with the mutation, require clinical surveillance while those proven to be unaffected
do not require additional clinical examinations. Furthermore early diagnosis of Rb by molecular
testing can enable and enhance clinical management, earlier treatment, follow-up care, carrier
screening, genetic counseling, prenatal diagnosis and reproductive planning in predisposed
families. Irrespective of the importance of molecular testing of Rb patients, in Pakistan only a
few clinical reports on Rb are available so, there was a dire need to find RB1 mutations in
Pakistani Rb patients and to set a molecular based diagnosis for poor affected families. Keeping
in view the importance of molecular diagnosis, in this study a reliable genetic test has been
developed to detect the RB1 germline mutations in Pakistani Rb patients.
During this study, 70 Rb patients including 38 unilateral and 32 bilateral cases were enrolled,
from different regions of Pakistan. By using direct sequencing method, seven novel and twelve
reported RBI mutations were found. The novel mutations included three frameshift mutations
(c.1116_1119delCACT in exon 11, c.1436_1437delAC in exon 16 and c.2060_2061insTCATT
in exon 20) and four substitutions (c.148G>T in exon 2, c.610G>T in exon 2, g.94G>C in exon
7, c.947A>T in exon 10 and g.1991G>C in promoter region) while twelve reported mutations in
146
22 patients included, 9 substitutions (c.160G>T in exon 2, c.289G>T in exon 3, c.751C>T in
exon 8, c.920C>T in exon 9, c.967G>T in exon 10, c.1072C>T in exon 11, c.1654C>T in exon
17, c.2063T>C in exon 20 and c.2359C>T in exon 23), one frameshift mutation (c.772_776del in
exon 8) and two splice site mutations (c.380+1G>T and c.1215+1G>A in intron 3 and 12
respectively). Mutation detection rate was found to be 77.8% in (7/9) bilateral familial, 50% in
(2/4) unilateral familial, 56.5% in (13/23) bilateral sporadic and 14.7% in (5/34) unilateral
sporadic patients while overall rate of mutations in bilateral and unilateral patients was detected
as 62.5% (20/32) and 18.4% (7/38) respectively. Beside mutations one novel c.940-64C>T
(intron 9) and nine reported intronic variants c.380+45 C>T (intron 3), c.501-77G>A (intron 4),
c.1128-72T>G (intron 11), c.1695+99A>T (intron 17), c.1695-1696delAA (intron 17), c.1815-
104A>G (intron 18), c.1961-10T>C (intron 19), c.2663+33T>C (intron 25) and c.2664-10T>A
(intron 25) were also found. Carrier screening facility was also provided to six asymptomatic
siblings (as possible carriers) of familial proband but none of them was found to be diseased.
Hopefully, in future the findings and developed protocol of this study will help to reveal the
molecular basis of Rb in Pakistani Rb patients which additionally help to secure vision and life
of Rb patients. Further, in Pakistan there is dire need to develop “National Rb Registry Centre”,
to register all new Rb cases for finding incidence rate and prevalence of Rb in Pakistan. Beside
this other related issues like financial constraints, health education, planning and awareness
about Rb, occupational training for health providers, capacity building for neonatal
ophthalmologic screening and cosmetic rehabilitation for surviving Rb patients are important and
should consider. Availability: Items available for loan: UVAS Library [Call number: 2370-T] (1).

Publisher: 2015Dissertation note: Infectious Bursal Disease (IBD) has become very notorious poultry disease in Pakistan. The disease affects the primary lymphoid organs (bursa of Fabricius) of the poultry and cause mild to severe immune suppression in affected birds. In accordance of the mentioned fact, present experimental project was designed to evaluate the effects of immune boosters after IBD vaccination and compare the effects of GarVit-Pro with only vaccinated birds. Humoral immune response against IBD virus was measure through Enzyme Linked Immunosorbent Assay (ELISA). There were total 90 bird, divided into 3 groups with 30 birds in each group. The blood sample were collected from different experimental groups of broiler chickens on 07, 14, 21, 28 & 35 days of age. Among the various experimental groups of broiler chickens the significantly highest antibody titer was recorded in group B fed with GarVit-Pro (Garlic Supplement) as compared to the other vaccinated and unvaccinated groups. The histopathological scoring of Bursa of Fabricius and thymus in different experimental groups was observed at day 07, 14, 21, 28 and 35. The bursal lesion scores of Group B (GarVit-Pro Treated) was lower than the other two groups. The GarVit-Pro helped to enhance the antibody titer against IBD virus after vaccination. These findings suggest and advocates that GarVit-Pro (garlic supplement) can effectively stimulate and enhance the immunity in broiler chickens. GarVit-Pro can be potential ameliorator against different vaccines and their unwanted/suppressive effects in broiler chicks. It was proved that GarVit-Pro is able to implement immune response and have a patent immunomodulatory effect in chickens Availability: Items available for loan: UVAS Library [Call number: 2363-T] (1).

Pathological Investigation Of Hydatid Cyst In Sheep And Goats At Lahore Abattoirs
by Syed Shan Raza (2013-VA-444) | M. Saeed Imran | Dr. Raheela Akhtar | Dr. Nisar Ahmad.
Material type: ; Literary form:
not fiction
Publisher: 2015Dissertation note: Hydatidosis is an important zoonotic disease caused by E.granulosus. The parasite causes production loss in meat industry by damaging lungs and liver of food producing animals which leads to decrease in body weight of animals. Animals suffering from Hydatidosis also slaughtered in abattoirs for meat production. These animals should be treated and proper control strategies should be adopted by deworming to control the production loss in meat industry. Histopathological findings are important to understand the reason for rejection of carcass along with viscera. The present study was designed to investigate the biochemical findings of hydatid cyst from lungs and liver of sheep and goats which can provide valuable information for determining the strains of E. granulossus, and to check current status of the disease at Lahore abattoirs, so that proper control strategies should be adopted to control this zoonotic disease.
A total of 1600 animals comprising 796 sheep and 804 goats of both sexes were examined for hydatid cyst in the month of August to November 2015 for determining the prevalence of E.granulosus in the particular time period. Total of 60 cysts samples from lung and liver of the sheep and goats were collected in the buffered formalin to check the biochemical profile for strain differentiation (30 from liver and lungs of sheep and 30 samples from liver and lungs of Goats). All the samples were collected form Lahore meat processing complex. The tissue samples of lungs and liver were subjected to histopathology. Histopathology was performed for lesion identification in tissues infected with hydrated cyst in the presence of viable and inviable cyst.
Summary
38
In present study, overall prevalence of hydatidosis in sheep was found as 7.91 %. In lambs, the prevalence was almost similar in males 1.23 % and females 1.44 % but in adults, it was significantly higher 10.74 % in females as compared with males 6.46%. The prevalence was significantly higher 7.91 % in adults than in hoggets 1.32 %. In goats the overall prevalence of hydatidosis was found as 5.60%, prevalence was much higher in adult males 4.38 % than in young ones 0.64 %. Similarly there was a significant difference in the prevalence between young 1.36 % and adult females 7.88 %. In the present study, overall prevalence in goats was recorded as 5.60 % which is significantly lower than the found in sheep 7.91 %. The prevalence was significantly higher in adult male sheep than that in adult male goats. It was observed that cysts removed from liver in both the species were more fertile than those of collected from lungs and also reported that hepatic cyst are more fertile than the cysts found in lungs.
The biochemical comparison helped in the characterization and identification of strains of E.granulosus at Lahore region. The obtained data was statically observed on student t test for the detection of mean difference in the biochemical profile of the both sheep and goat cysts. Statically there was significant difference found in the total Glucose, triglycerides, and cholesterol, levels in hydatid cyst fluid obtained from the sheep and goats. These difference was due to the strain variation of E.granulosus. There was no significant difference in the biochemical levels of urea, uric acid, total protein, creatinine, calcium and phosphorous. The level of glucose and triglycerides in sheep was 6.3 and 0.63 mmol/lit respectively which was significantly higher than hydatid cyst fluid of goats i.e., 4.2 and 0.39 mmol/lit respectively. The level of the cholesterol in sheep was lower than that of goats which was 0.14 and 0.39 mmol/lit respectively.
Study helped us to know the current status of Hydatidosis in small ruminants at Lahore which causes production loss in meat industry. The biochemical examination of cystic fluid helped us to know about the probability of the status of strains of E.granulosus present. Current biochemical profile indicates probability of two strains of E.granulosus are prevalent at Lahore for strains characterization and identification further studies are needed. The histopathological study helped us to find out the pathological changes at the tissue level in the presence of cyst in the tissues of the lungs and liver of sheep and goats.

Isolation And Molecular Detection Of Salmonella Species In Milk And Milk Products
by Muhammad Umar Ijaz (2007-VA-040) | Prof. Dr. Mansur-ud-Din-Ahmad | Dr. Muhammad Hassan Mushtaq | Dr. Ali Ahmad Sheikh.
Material type: ; Literary form:

Publisher: 2015Dissertation note: Salmonellosis is one of the emerging zoonotic diseases. Human infections result from contaminated raw or undercooked food. Various sources of contamination in milk are dirty udder, unhygienic handling and utensils, dirty hands of milkmen and poor quality water supply at the farm. To ensure food safety there is a dire need for the availability of valid, rapid and accredited diagnostic system. Conventional culture methods for detecting Salmonella spp. in foods needs 4–5 days. The development in molecular techniques made it possible to cut short the procedure.
The present study was conducted with the aim to evaluate the burden of Salmonella spp. in milk and milk products. In total 150 samples were collected, out of which there were 75 milk samples. These samples were collected from farm dairy herds (pooled milk) located in Harbanspura Dairy colony, Lahore. Salmonella was detected in 8 samples (11%) by conventional method.
In addition to milk samples, 75 samples of milk products were also collected from retail shops. These include 50 samples of Yogurt and 25 samples of Yogurt milk. Milk products had 6 positive samples (8%). No sample of Yogurt was detected positive for Salmonella. The reason for this is that Yogurt had only Salmonella if it is present in starter culture. Furthermore yogurt is made after frequent heating. Salmonella is killed by such continuous and vigorous heating. Yogurt milk is prepared from Yogurt along with raw milk in a separate utensil. There are chances of contamination there so it had 6 positive samples. Total 14 (9%) samples were detected in 150 samples by conventional method. It was found that Salmonella was present in raw milk samples and milk products at places where either cleanliness was not proper, milk handling practices

were not up to the mark, udder was not washed before milking or overall management practices were poor.
Positive samples obtained by conventional method were further analyzed by PCR for Salmonella genus confirmation. Out of total 8 positive milk samples by conventional method, 5(62%) were confirmed as Salmonella genus. Similarly from 6 positive samples of milk products by conventional method, only 2(33%) were confirmed as of Salmonella genus. Further PCR was conducted for Salmonella typhimurium detection. Milk samples were containing 3(60%) positive samples while no positive sample was detected in milk products.
On the basis of the results of present study, it is recommended that milk should always be boiled before use. Further Hygienic measures should be adopted during milking. Proper handling of milk and milk products is also important to limit the cross contamination. It is also advised that standards such as pasteurization and HACCP should be introduced to facilitate production of good quality milk. Electronic and print media should also create awareness among people about food safety. Availability: Items available for loan: UVAS Library [Call number: 2408-T] (1).

Control Of Gastrointestinal Nematodes By Anthelmintics In Buffalo Heifers And Its Effect On Weight Gain
by Tanveer Saroia (2008-VA-062) | Prof. Dr. Khalid saeed | Dr. Nisar Ahmad | Dr. Ali Ahmad Sheikh.
Material type: ; Literary form:

Publisher: 2015Dissertation note:
Parasitic problem is a major constraint of ruminant production and causes great economic losses to dairy industry by retarded growth, low productivity and increased susceptibility of animals to other infections. The parasitic infections cause productivity losses through reduced feed intake and decreased feed efficiency. Even subclinical or chronic infections are responsible for economic losses in large ruminants.
Hypothesis of the study was that administration of anthelmintics will improve weight gain in infected buffalo heifers.
One hundred faecal samples of buffalo heifers of age 1-2 years were screened and 58 were found positive for gastrointestinal nematodes. The species of nematodes found prevalent in these animals were Trichostrongylus, Oesophogostomum, Haemonchus, Toxocara, Trichuris and Ostertagia. Thirty buffalo heifers with high EPG were selected and divided into 3 equals groups A, B and C. In this study Group A was a positive control group. Group B was administered Ivermactin (Bomectin) pour on at the dose rate of 1ml / 20 kg body weight. Group C was administered Oxfendazole (Systamex) orally at the dose rate of 1ml/ 10 kg body weight. The effect of these anthelmintics on EPG and weight gain were recorded after every 15 days. This study period was of 90 days (3 months) duration.
There was increases in the EPG of positive control group and percent increases was 7.10%, 10.65%, 18.10%, 30.17%, 33.72%, 46.15% at days 15, 30, 45, 60, 75and 90. The percentage decrease in EPG for the group B was 98.22%, 97.04%, 91.12%, 77.51%, 60.94%, 46.74% at days 15, 30, 45, 60, 75 and 90 post treatment and the percentage decrease in EPG for the Group C was 95.80%, 92.81%, 88.62%, 71.85%, 58.68%, 26.34% at days 15, 30, 45, 60, 75 and 90 post treatment. Both anthelmintics cause significant reduction in epg medicated animals as compared to non-medicated animals. There was no difference in the two anthelmintics. The average weight gain per day for Group A (Positive Control) is 0.17 kg per day, for Group B (Ivermectin) is 0.44 kg per day and for Group C (Oxfendazol) was 0.4 kg per day. This shows significant difference between treated groups with non-treated group but there was no difference between the treated groups.
It is concluded that ivermectin and oxefendazol can be used for the control of gastrointestinal nematodes. It is recommended that animals may be moved to clean facility after treatment so they are not reinfected. Repeated treatment is suggested to maintain the EPG at low level.
Suggestions of the present study are
1. Monitoring of animals for gastrointestinal nematodes by modified McMaster Egg Counting technique.
2. Regular deworming
3. Improved management

Publisher: 2015Dissertation note: Tick infestation and the resulting transmission of serious pathogens in ruminants is one of the most important problems of the livestock industry in developing countries (Aktas et al. 2012).Bovine babesiosis is economically the most important tick-borne disease of cattle worldwide including areas of Australia, Africa, South and Central America. Babesia species are protozoan parasites that parasitize the erythrocytes of domestic animals and humans, causing Anemia in the host affected. Polymerase chain reaction (PCR), which is more sensitive and specific technique, offers an alternative approach for the diagnosis of Babesiosis (Zulfiqar et al. 2012).
Geo-climatic condition of Punjab, Pakistan favours the multiplication and survival of ticks which play a major role in the biological transmission of Tick Born Diseases. In earlier reports the prevalence of cattle tick infestation was more than 50% from Punjab (Durrani et al. 2008, Sajid et al. 2009).
Keeping in views the importance of the disease, the present study was carried out to determine the prevalence of Babesiosis in cattle of Lahore, District of the Punjab, Pakistan. A total of sixty (60) blood samples was collected randomly from dairy cattle of District Lahore. These samples were transported to the Laboratory of Parasitology, Department, University of Veterinary & Animal Sciences, Lahore and were kept at 4oc until further processing for Microscopic examination (Zakir et al. 2014) and then for PCR. We focused on the early detection of Babesiosis through Microscopic examination of Blood samples. For further confirmation of Babesiosis, the blood samples were processed through Polymerase Chain Reaction (PCR) as described by Zulfiqar et al. 2012.
The thick and thin smears of the blood samples were made on the new particularly labeled glass slides. The dried blood smears were fixed in absolute methyl alcohol for one

Staining was performed using Giemsa Stain as method followed by Zakir et al. 2014 i.e. the glass slides bearing thick and thin blood smears were stained with one fourth of dilution of commercially available Giemsa stain for four minutes and were observed under oil immersion at 100X objective to detect the presence of Babesiosis.
All the blood samples were examined through Microscopy showing 04 positive ones, then all the samples were processed using PCR for final confirmation of Babesiosis in Cattle. PCR was performed under the conditions as previously described by Zulfiqar et al. 2012. PCR reaction was performed to obtain amplified products over 30 cycles by 94ºC for 5 min., 94ºC for 30 sec., 50ºC for 30 sec., 72ºC for 45 sec. and completed with a final extension step of 7 min. at 72ºC. Finally the amplified DNA fragments were analyzed after electrophoresis on 1.5% agarose gel.
Prevalence rate will be determined with the help of the following formula:

Publisher: 2015Dissertation note: Gastrointestinal helminths are responsible for wide range of health problems, economic losses in camels and are characterized by impaired milk and meat production, decreased working efficiency and even death of the camel. Gastrointestinal nematodes cause losses through morbidity, decreased feed intake, poor efficiency of nutrient and reduced growth.
To study the gastrointestinal helminths 384 camels of different age, sex and breed were examined coprologically. For this, five gram of fresh faecal sample was carefully collected into a sealed container from each camel and was transported to Disease Diagnostic laboratory Muzaffargarh. Where direct faecal smear method was performed in order to verify positivity of faecal sample. Positive sample was preserved in 10% formalin and transferred to Medicine lab, UVAS, Lahore for further procedure. Faecal samples were scored 1-3 based on the consistency. The individual samples was triturated in saturated salt solution, sieved and examined for helminths eggs by using different techniques i.e. Direct Smear Method, Sedimentation technique and Floatation technique while the eggs count was performed by McMaster technique. The overall prevalence of gastrointestinal helminths in the camels was 40.10%. The study showed that there were frequent infections with different species of helminths. Six different species of helminths were identified in camels, they were broadly classified as nematodes (4 species), Trematodes (1 specie) and Cestode (1 specie). Among these helminths nematodes, trematode and cestode order of intensity are 33.07%, 3.38% and 3.64%. In nematodes Haemonchus spp 9.11%, Trichostrongylus spp 5.98%, Trichuris spp (4.16%), Nematodirus spp (2.60%) and mixed (11.19%).
Summary
42
Among the camel population, overall prevalence of Fasciola hepatica and Moniezia expansa was recorded 3.38% and 3.64%.respectively. The prevalence of helminths in relation to sex was 34.55 % in male and 43.14% in females. However there was no statistical difference between the prevalence of females and males (P>0.05). Study was also conducted to determine the influence of age on the prevalence of helminths which revealed that there was no statistical significant association (P>0.05) between those groups. Between the age groups prevalence was 45.09% in <5 Year old and 36.79% in >5 year old. The breed wise prevalence in Mareecha and Brella breeds was 42.85 % and 36.78% respectively which was statistically non-significant (P>0.05). For therapeutic trials, a total of 40 camels positive for helminths and having EPG >400 were randomly selected and divided into four groups A-D each group comprising of 10 animals. The dosage of herbal drugs was calculated on the basis of preliminary trials in other species. The camels of group A were orally treated with Artemisia brevifolia (Afsanteen) at dose rate of 10mg/kg BW, while camels of group B were given Mallotus philipinenesis (Kamela) powder at a dose rate of 375mg/kg BW. Camels in group C were treated with Albenzole granules® (Selmore) at a dose rate of 15mg/kg. b.wt. PO once. Camels in group D were serving as positive control (infected-untreated). Efficacy was determined on the reduction of eggs in feces at day 3, 7 and 14 (post-treatment). In current study A.brevifolia (Afsanteen) and M.Phillippinensis gave satisfactory results in the camels affected with helminths. A.brevifolia (Afsanteen) showed a mild to moderate reduction in EPG count from day 3rd to day 14th in camels. Mean EPG values calculated on days 0, 3, 7 and 14 were 670, 570, 385 and 275 respectively. A.brevifolia (Afsanteen) cured 23.88% of the animals on day 3rd of the drug administration while 42.53% and 58.95% animals cured on the day 7th and 14th respectively. M.Phillippinensis showed mild reduction in mean EPG count on 14th day of post-treatment. Mean EPG values calculated on days 0, 3, 7 and 14 were 440, 400, 355 and 310 respectively. M.Phillippinensis also gave good results
Summary

against helminths affected camels. On the day 3rd of the treatment 19.31% of animals cured while 29.54% animals were cured on the 7th day and on 14th day 44.31% animals recovered. Albendazole showed marked dropped in EPG count from Day 3rd to day 14th. Mean EPG values calculated on days 0, 3, 7 and 14 were 560, 195, 95 and 35 respectively. Albendazole efficacy was 31%, 68% and 82% on 3, 7 and 14 days of treatments. Control positive showed consistence increased in EPG count from day 3 to day 14. Data regarding prevalence were measured by non-parametric, chi-square (χ2), while therapeutic trails were analysed by repeated measures one way ANOVA, using SPSS (Statistical package for social sciences) 20.0, P < 0.05 was considered significant.
