Publisher: 2016Dissertation note: This study was mapping the genetic diversity of Cirrhinus mrigala by using molecular markers for the ATPase 6/8 gene region. Samples of the target fish specie were collected from the different sites at the Indus riverine system of the Pakistan i.e Chenab (Head Qadirabad), Jhelum(Head Rasul), Ravi(Head Balloki) and Indus (Head Taunsa). Morphommetric parameters viz., Body weight, Girth, Total Length, Fork Length,Head length, Lengths of Caudal, Pectoral, Ventral Fins were recorded manually using measuring scale. After recording morphometric parameters blood from fish samples was drawn from caudal fin of the Fish, collected in Vautainer and immediately transferred into the Lab of IBBT where it is preserved in -80C for future use in DNA extraction. Phenol Chloroform Method of Genomic DNA extraction was used to extract whole blood DNA. The extracted DNA of the samples was run on 0.8% agarose gel by using electrophoresis of the DNA. Nanodrop was used to find out the concentration of DNA after that DNA was diluted according to the Need with deionized water. The PCR of ATPase 6/8 primers were used to amplify the target gene. The PCR product was confirm on 1.2% agarose gel. These gels were visualized in UV light and photographs were taken by Gel Documentation System (BIO-RAD, Gel-DOC EZ imager). After the visualizing of quality of band confirmation the samples were sent to be sequencing. The Analysis of Variance (ANOVA) for the different morphometric parameters was done by XLSTAT 2012 version 1.02. ANOVA results showed that all the morphomteric parameters were highly significant (p<0.01) within as well as between the groups. Pearson correlation analysis off overall population show that the body weight is positively correlated with the Fork Length, Total Length, Ventral Fin length, caudal Fin Length, Girth, with significant difference. Fork length is positively correlated with Total length, Ventral
Fin Length, Caudal Fin length, Pectoral Fin Length, with significant difference among other parameters. Total Length is positively correlated with Girth, Pectoral Fin Length, Ventral Fin Length, Caudal Fin Length, Girth, and Weight with significant difference among them. NJ methods suggested that existed relationship among different species located at different geographical locations. They all have a common ancestry. A strong relationship exists between fish species collected from different locations at Indus riverine system of Pakistan.

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.

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: Present study was planned to compare egg quality, hematology and reproductive traits in ring necked and green pheasants in captivity. Day-old chicks of both the pheasant species Phasianuscolchicusand P.versicolorwere tagged individually and maintained initially in a room for a period of 4 weeks. The chicks were then transferred to cages provided with separate feeding and drinking facilities to the individual bird. The birds were kept until the 16 weeks of life. The sex of the chicks was predicted at early stages by observing feathers and plumage and was confirmed later at adult ages.
Eggs (n = 100) of both the pheasant species i.e. Phasianuscolchicusand P.versicolorwere collected. Each egg was weighed and its length and breadth was taken. These eggs were divided into three weight groups and were classified as light, medium and heavy category. The length and breadth of each collected egg was taken and surface area, egg volume and shape index were calculated.The egg quality test was performed on freshly collected eggs in the egg quality testing laboratory periodically. The eggs were weighed carefully on electronic digital balance. The albumen and yolk height and width, yolk index, albumen and yolk pH and Haugh unit score were recorded.
During present study, chick weight in ring necked pheasants Phasianuscolchicusand green pheasant P. versicolorfrom day old chick to 6-month stage varied significantly. The average body weight in day old chick weight ranged from20.6±1.35g to 24.50±1.29g.Increase in chick weight in male ring necked pheasants was 24.50±1.29g to 1235.25±101.81g. Similarly increase in female ring necked pheasant was 22.47±1.79gto 1004.75±52.94g.The chick average weight was almost double during 2nd week. Body length was maximum in male green pheasant 5.00±0.81cm during 1st week. However significant (p<0.05) increase in body weight was observed during 1st to 4thweek.Higher increase in average body weight was observed during 6thweek. Significantly (p<0.05) increase in wing length and wing span was also recorded during 6th week. During 7thweek, non-significant differences in body weight were observed between male and female P. colchicus.Overall, minimum increase in chick weight was observed during 21st,22nd and 23rd week and maximum during 6th,7th and 8th week of chick age. The chick weight at hatching in light, medium and heavy egg groups were determined as 19.5g, 21.8g and 22.6g, respectively.
Lowest increase in chick body weight in green pheasants ranged from 20.6±1.35g during 1st week to 837.00±49.45g during 24thweek of its growth. During present study it was determined that hatched chick weight increases with increase in egg weight. After completion of the incubation, the infertile egg percentage was 48% in ring necked pheasant and 42% in green pheasant. Increase in wing length varied significantly in male and female and between both species from day old chick to 6-month stage. The lowest increase in chick’s wing length ranged from 5.37±1.10cm to 33.75±1.70cm in female P. versicolor. Overall minimum increase in wing length was observed during 12thweek and maximum during 2nd,3rd and 6th week of chick age.
During present study, significant differences in various hematological parameters were recorded during different ages of pheasants. RBCs values in P.cholchicusincreased with age, reached a maximum point then decreased. While in P. versicolorthe values decreasedat juvenile stage and then increased to young ages and decreased. However, maximum 4.04±0.6 values for RBCs were recorded in P. versicolorduring 3rd month. In young age,significant (p<0.05) differences in blood biochemical profile of both the pheasant species were observed.

Publisher: 2016Dissertation note:
Metallic and non-metallic pollutants originating from different industries are not treated before their final discharge into the environment. Consequently, environment is being degraded very rapidly and posing serious threats to all forms of life. For remediation of the said pollutants, a number of physico-chemical treatment methods have been practiced but couldn’t found suitable due to environmentally non-compatible natures and generation of secondary pollutants.
The present study was, therefore, designed to treat artificially prepared sulfate-rich wastewater jointly with the help of cellulolytic and sulfate-reducing bacterial species while using a variety of agro-industrial wastes as cost-effective growth substrates. In order to achieve the goal, the two bacterial species were mixed in different proportions to achieve significant results of sulfate reduction.
Statistical analysis revealed that rice straw appeared as the most efficient carbon source among all the agricultural wastes because it reduced about 96% of the total added sulfate in a 60-day trial of anaerobic incubation. And among all the industrial wastes, animal manure appearedasthe most efficient carbon source, it could reduce 93% of sulfate. Mixture of industrial and agricultural waste reduced about 90% of the sulfate. Findings of this project will be helpful in developing an economical and environmental friendly bio-remedial technique for the treatment of metallic and non-metallic wastes simultaneously which ultimately convert the industrial wastewaters into harmless and suitable discharge to aquatic environment.

Publisher: 2016Dissertation note: Toxoplasmosis is the furthermost zoonosis globaldiseases which isinitiated by the protozoan parasite Toxoplasma (T.) gondii. Felidae,(Felis silvestris) are the only definitive hosts.All warm-blooded vertebrates, mammals and birds, turn out to beseptic by consumption sporulated T. gondii oocysts in the environment or by ingesting T. gondii tissue cysts within the tissues of intermediate hosts. Climatic aspects influence the oocysts in the atmosphere. Tropical countries have higher seroprevalence due to humid and warm climate.The main reason of human seroprevalence, are dietary habits (categories of meat or vegetables consumed, cooking technique of meat,vegetable cleaning, hand washing, etc.) economic, cultural social habits, quality of water, and sanitation coverage. Pet birds are act as natural pools for many pathogens. The lifeless infected birds eaten by cats, the catscome to be infected and afterwards eliminated oocysts.
The current study wasdesigned toconclude the seroprevalence of T. gondii in captive birds (Domesticated and caged) in district Kasur and Lahore, Pakistan.The study area was comprised of two geologically altered districts. Fifteen different sampling sites areas were UVAS-C and A-block, Pattoki; Defence Colony, Kasur; Village Kyloon Kalan, Kasur; Kyloon Khurd, Kasur;Khudian Khas, Kasur;Gulburg Colony, Kasur; Kacha Paka, Kasur; Dowlay Wala, Kasur;Pet Market, Pattoki; Tollinton Market, Lahore;Elahabad City, Kasur; Village Wadana, Kasur; Mustafa Abad, Kasur; The Educator School, Pattoki.
A total of 200 bird’sblood samples were collected. All birds’ sample were collectedrandomly from Pet Markets (n = 44), Captive Breeding Centres (n = 93)and Homes (n = 63).
One ml of blood was taken from wing vein and stored in sterile clean test tube.Serum samples were analyzed using Latex Agglutination Test (LAT).Thirty seven serum samples (18.5%) were found to be seropositive for T. gondii antibodies out of 200. Apparently, highest seroprevalence (66.7%) was documented inDefence Colony, Kasur and no seropositive case was reported from Mustafa Abad, Kasur and The Educator School, Pattoki.
Several parameters(order/species, habitat, feeding and drinking behavior and environmental conditions of the birds) were observed for the seroprevalence of T.gondii antibodies. In order, Galliformes 11.9%, Anseriformes15.8%, Psittaciformes 29.4% Columbiformes, 22.4%,Passeriformes 41.7%were seropositive for antibodies against T. gondii by Latex Agglutination Test.According to species level parameter, the Turkey (Meleagri gallopavo) 20%, Indian Peacock(Pavo muticus) 5.6%, Common Quail(Anser domesticus) 10.7%, Duck (Bucephala albeola) 17.2%, White Goose (Corturnix coturnix) 11.1%, Grey Parrots (Psittacus erithacus) 50%, Budgerigar (Melopsittacus undulatus)20%,Fischer's Lovebird (Agapornis fischeri)25.0%, Sulphur-Crested Cockatoo (Cacatua galerita) 50%, Dimond Dove(Geopelia cuneata) 50%,Eurasian collared-dove(Streptopelia decaocto)40%, Khumra33.4%,Rock Pigeons (Columba livia) 11.2%, Domestic Pigeons (Columba livia domestica) 27.3%, Tricoloured Munia (Lonchura malacca)50%,Zebra Waxbill (Amandava subflava) 50%, Society Finch(Lonchura striata domestica) 75% were seropositive for T. gondii antibodies.None of White Peahen(Pavo cristatus),Desert Finch(Rhodospiza obsoleta), Guinea fowl(Numida meleagris),and White-throated Munia (Euodice malabarica) serum sample was seropositive for T.gondii antibodies.
Gender wise study shows that out of total sera samples male seroprevalence rate were20.9%,while in the female 16.8%. Out of total samples in domesticated birds the seroprevalence rate were14.3%, breeding centers 15.1%,pet market of districts Kasur and Lahore 31.9%.The rate of seroprevalence in natural source drinker were 20.4%, while in contaminated drinker were 14.4%.
The present study provided evidence of T. gondii infection in domesticated and caged birds in district Kasur and Lahore, Punjab, Pakistan. As, T. gondii is zoonotic agent which can be transferred from these birds to human being having close contact with them. There is dire need of prevention and control of said diseases in our domesticated and caged birds.

Publisher: 2016Dissertation note: In Asia Carp culture is dominated which is mostly extensive and semi-intensive. Now a days aquatic plants used in animal feed became very popular. Aquatic plants have been used to enhance the growth, reduce stress, induce appetite and play a major role as Immunostimulants that have antimicrobial effects in fin fish and shrimp. However, exact percentage contribution needs to be determined to obtain its benefits as over dose can have harmful effects. These plants are mechanically removed at a high costs and dumped. So, the use of unusual feed resources is a way of significant reduction in the cost of feed.
Addition of Aquatic plants upgrade growth, enzyme level, body composition and immunity of Labeorohita (rohu) fingerlings.This study will produce useful information for aqua feed and fish industry concerning possible utilization source of aquatic plants for carp. It will also be helpful to save the increasing cost of aqua feed industry because of cheaper source of energy inproving health of fish thus enhance production.
To compare the growth performance and meat quality of Labeorohitaunder different treatments
Experiment was designed in glass aquariums and with two replicates in each treatment. The effect of inclusion of aquatic plants in the feed of Labeorohitawas also observed on histology under different treatments in aquariums. Before stocking all aquariums was disinfected with KMnO4. Each aquarium was stocked with 15 Labeorohitafingerlings and their morphometric parameters i.e,body weight and total length was recorded at the time of stocking. The physico-chemical parameters (DO, pH and Temperature) was monitored on daily basis from each treatments. For proximate and histological studies organs of fish was collected at the end of experimental. The feed was formulated for treatment T1, T2, and T3 having 35%, 30% and 25% of plant (Vallisneriaspiralis). The fish samples were captured randomly from each of the treated aquarium and their morpho-metric characteristics viz. total body weight and total length were recorded on weekly basis. And after obtaining the data the fish were released back into their respective aquarium. At the final harvest, the proximate composition of fish meat sample was studied.
The findings of the present experiment are summarized as follow.
1-The average body weight of Labeorohitaremained as 91.2, 71.3, 62.2 and 58.2g under the treatments T1, T2, T3 and T4 respectively.Fish attained the maximum average body weight in T1 which was treated with 35% plant.Among the different treatment, maximum body increment in body weight was recorded in T1 as 91.2(g) whereas minimum body weight was recorded in T4 as 58.2 (g)..
2-Labeorohitashowed the minimum value of specific growth rate as 0.422 and 0.463 in T3 and T4. Maximum value of 0.789% of specific growth rate was noted in T1.
3-Among different treatments the maximum condition factor was observed as 2.717% in T1 while minimum was gained as 1.918% in T4.
4-Among different treatmentsLabeorohita showed the highest growth rate with the highest crude protein contents 18.70% under the treatment T1. while17.85%, 17,60% and 17.35% in T2, T3 and T4.
5-The maximum moisture content was observed as 75.22% in T1 and minimum moisture content was observed as 73.20% in T4
6-The maximum value of total fats was observes as 1.29% in T4 and minimum value was observed as 1.13% in T1 treatment
7- Among the abiotic factor water temperature played major role towards fish growth as higher increase in body weight was observed for all the treatments during July and august while minimum increase in body weight was observed in September and October which perhaps due to low water temperature.Maximum water temperature was observed as 24.6 °C in T1 and T3 treatments. While minimum was recorded as 21.3 °C.
8-The physico-chemical characteristics of water remained within the favourable limits for fish culture.and shows non-significant under all treatments.
