Publisher: 2011Dissertation note: Pakistan is the third largest goat producing country in the world after China and India. According to the economic survey of Pakistan 2010-2011 the population of goats stood at 61.1 million and their population is increasing at the rate of more than 3% per annum. The study was designed to investigate the effect of Bovine Somatotropin on milk production, composition, and weight gain and biochemical parameters in lactating Beetal goats at Small Ruminant Training and Research Center at Ravi campus Patoki, University of Veterinary and Animal sciences Lahore, Pakistan. Fifteen lactating Beetal goats of almost same age, body weight, and parity were included in this study. The goats were divided into three group's i.e A, B &C. Five animals in each group according to the lactation stage, parity and milk yield. Group A was used as control group, while B & C were subcutaneously injected with 50 & 100 mg /week of rbST for 8 weeks.
The treatment of goats with rbST rapidly increased milk yield after the onset of treatment. Statistically there was significant difference among the treatment (p<0.05). Highest increase in milk yield (29 %) was observed in group C that was treated with 100 mg of rbST. Non significant difference was noted between 50 mg and 100 mg treatment groups. Milk samples were analyzed for, protein, lactose, ash, total solids and fat. However slight increase in milk protein, lactose, ash, total solids and fat (9.33, 10.42, 3.92, 3.22 and 8.81 %) was observed respectively. However statistically there was nn significant difference was observed among the treatments.
Body weight (BW) of the does was not significantly affected by rbST treatment. Highest increase in weight was observed in group B (1.53 %). Statistically non significant differences were observed between the treatments.
Blood plasma samples were analyzed for Total protein (g/dl), Albumin (g/dl), Globulin (g/dl), Glucose (mg/dl), Urea (mg/dl), Creatinine (mg/dl), Total bilirubin (mg/dl), Cholesterol (mg/dl). A slight increase in plasma protein, cholesterol, albumin, was observed during the treatment period. However statistically non significant difference was observed among them. Plasma glucose level increase significantly (P<0.05) during the experiment period. Highest increase in plasma glucose (92.14 %) was observed in treatment group B, while slight decrease in plasma creatinine, globulin, urea and total bilirubin was observed during the whole experiment period. However statistically there was non significant difference was observed among the treatments.
On the basis of above mentioned facts and figure it is concluded that 50 mg/wk dose of rbSt is efficacious in increasing milk yield without any adverse effect on lactating Beetal goats.

Publisher: 2015Dissertation note: In a developing country like Pakistan, livestock sector has a significant importance.
Meat is an important food component in human diet and its source varies from different
organisms like cattle, buffalo, camel, deer, sheep, goat, rabbit and chicken etc. Small
ruminants especially sheep, has a unique role in meat production, due to its feeding and
adaptive behavior. The myostatin (MSTN) gene is known as a candidate gene for
development and growth of livestock because it plays its major role in muscle growth.
Selection is an important tool to improve the meat production and thus enhance the economic
conditions of livestock farmers. For this purpose genetically characterization of meat type
animals, especially the indigenous sheep breeds is not common. The variations in the
myostatin gene have been extensively studied and reviewed in small and large ruminants in
the world but it has been scanty studied in sheep breeds of Pakistan. Thalli and Pak-Karakul
are well known sheep breeds present in Punjab, Pakistan. This study aims to characterize the
genetic variation in the myostatin gene in Thalli and Pak-Karakul sheep breeds.
In this research study, twenty adult animals of two different sheep breeds (Thalli and
Pak-Karakul) were selected from Small Ruminants Research and development Centre, Rakh
Khairewala, District Layyah, Pakistan. Five mL blood sample was collected from each
animal in a 15mL falcon tube containing anticoagulant. Primers were designed by using
Primerfox online software. Primers were optimized using specific protocol and PCR was
performed. DNA was extracted using modified inorganic method of Sambrook et al. (1989).
PCR was carried out using all primers and later sent for sequencing to 1stBase Laboratories,
Singapore. Molecular analysis was done using CodonCode Aligner and MEGA6 softwares.
Ten samples of each breed were sequenced to detect polymorphism in both Thalli and
Pak-Karakul sheep populations. Sequencing revealed G↓T transition at 3995 position in
Summary

genome (accession number, DQ530260.1) in Thalli and similar transition in Pak-Karakul at
the same position. In Thalli sheep 50 % of experimental animals were heterozygous, higher
level of heterozygosity makes it a potential candidate for higher growth rates. On the other
hand the Pak-Karakul sheep is medium weight breed and frequency of mutant allele was 0.2
or 20%. The observed heterozygous individuals were also with higher live body weights. The
gene frequency shows that this breed has medium potential for its body growth. The
information‟s so generated and further association studies in both breeds will be helpful in
devising breeding plans for increasing mutton production at national level. Availability: Items available for loan: UVAS Library [Call number: 2288-T] (1).

Publisher: 2016Dissertation note: Silage production is at initial stages to be a part of animal agriculture in Pakistan. The lack of research on silage making and its benefits for livestock production under local conditions is an important factor for slow propagation of silage in our country. Under such scenario a multi-step study was conducted. At first, the effect of proper maturity stage for harvesting different fodders was investigated, and then the effects of silo type and silage additives were assessed on silage quality. In last part of the study the feeding trials were conducted on growing calves and lactating buffalo to evaluate the effect of silage feeding on growth and milk production respectively.
In all the three fodders i.e. oats, maize and sorghum, the full bloom stage for harvesting produced the best results regarding silage quality and fermentation characteristics. Although the trench silo produced best results regarding fermentation characteristics and silage quality, the expected operational cost and dry matter losses during face management for trench silo would make it harder for farmers to adopt. Under such circumstances, for long term use the bunkers would be a good choice for silage making with comparable silage quality as that of trench silo. Silage inoculants certainly improved the silage quality and it is highly recommended to use such additives for silage making and these additives are not that costly. Buffalo calves raised on fresh corn fodder and three different silages showed similar daily weight gain. Further growth trials on buffalo calves with varying levels of concentrate feeding along with silage are suggested to investigate silage feeding in calves. Corn silage fed lactating buffaloes had lower dry matter intake and total milk yield, but higher total solids as compared to fresh fodder feeding. The future studies of silage feeding compared to different inclusion levels of fresh and dry roughage sources would add further to explore the economic implications of silage feeding.

Publisher: 2012Dissertation note: During last few years, rate of the use of yeast in dairy animals feed had greatly been increased. The use of live yeast culture (Saccharomyces cerevisiae) in feed of ruminants and especially of goat is being used throughout the world. The effect of the live yeast culture (Saccharomyces cerevisiae) in vitro and in vivo conditions may vary widely. Yea-Sacc1026 is a live yeast culture which consists of Saccharomyces cerevisiae strain 1026, a yeast strain specially selected for its influence on animal performance. Yea-Sacc1026 is ideal for beef, dairy, calf and equine feeds. In the present study, eighteen lactating Beetal goats each having approximately same body weight and age, were selected from the flock. These goats were randomly divided into three groups A, B and C of six animals in each group. All the animals were offered similar concentrate ration @ 500gm/day to meet their daily requirements. Alltech's product "Yea Sacc" was added in the concentrate ration of lactating Beetal goats. In group Aeach goat was fed @500 gm concentrate ration (without treated with Yea Sacc) per day. In group B each goat was fed @ 500gm concentrate ration (treated with Yea Sacc @ 1.5 gm/goat) per day. In group C each goat was fed @ 500gm concentrate ration (treated with Yea Sacc @3gm/goat) per day. The effects of Yea Sacc on milk production, milk quality, weight gain and dry matter intake were evaluated.The mean milk production of goats treated with yeast in groups A, B and C were 0.6417 ± 0.067, 0.8600 ± 0.066and 1.0267± 0.146litters, respectively. The analysis of variance of experimental groups was significant between groups. The mean milk fat percentage of goats treated with yeast in groups A, B and C were 4.3133± 0.004, 4.4417± 0.010 and 4.5900± 0.042 % respectively. The analyses of variance of experimental groups were significant between groups. The mean milk protein percentage of goats treated with yeast in groups A, B and C were 3.1167± 0.014, 3.2783± 0.012 and 3.2867± 0.003%, respectively. The analysis of variance of experimental group are non significant between treated groups. The mean milk lactose percentage of goats treated with yeast in groups A, B and C were3.6083± 0.014, 3.6400± 0.006and 3.6583± 0.006%, respectively. The analyses of variance of experimental groups were significant between treated group and group A. The mean milk ash of goats treated with yeast in groups A, B and C were0.5100± 0.004, 0.5300± 0.004and 0.5483± 0.014 %, respectively. The analyses of variance of experimental groups were significant between the treated groups and group A. The mean milk total solid of goats treated with yeast in groups A, B and C were 11.5483± 0.018, 11.8983± 0.013and 12.0750± 0.005%, respectively. The analyses of variance of experimental groups were significant between group A and group C. The mean weight gain of goats treated with yeast in groups A, B and C were 0.218 ± 0.010, 0.285 ± 0.031 and 0.442 ± 0.019 kg, respectively. The analysis of variance of experimental group were significant between the treated groups and group A while non significant between group A and group B. The mean dry matter intake of goats treated with yeast in groups A, B and C were1.2133± 0.008, 1.2183± 0.012and 1.2383± 0.014%, respectively. In above experiment group C animals were fed 3 gm yeast had shown high milk production, fat %, protein %, lactose %, ash %, total solid %, weight (kg) and dry matter intake (kg) than other groups.
Data on milk yield, composition, growth rate and dry matter intake of Beetal goats were evaluated.
The data obtained was analysed through one way analysis of variances of (ANOVA) (Steel et al. 1997). The difference among treatment means were tested through least significance difference (L.S.D) (Steel et al, 1997).
