Identification Of Molecular Markers In Bmp15 Gene Of Different Pakistan Sheep And Goat Breeds

by Ahmad Nawaz | Prof.Dr.Masroor Elahi Babar | Prof. Dr | Prof. Dr. Khalid Javed.

Material type: book Book; Format: print ; Nature of contents: biography Publisher: 2011Dissertation note: Genetics of prolificacy in sheep and goat emphasize the importance of main genes which have been made known to affect litter size and rate of ovulation through various mechanisms. Natural mutations in prolific sheep and goat breeds have shown that the transforming growth factor beta (TGF-?) super family ligands such as bone morphogenetic protein 15 is crucial for ovulation and as well as for increasing litter size. Keeping in view the importance of prolificacy in sheep and goat, a research project was planed to identify the polymorphism, its association with fecundity and uncovering the nucleotide picture of BMP15 fecundity gene in sheep and goat breeds of Pakistan. In the research finding, various polymorphism, insertion and deletion of nucleotides in goat and sheep breeds of Pakistan were identified and associated with fecundity and secondly, some novel polymorphism in Pakistani goat and sheep breeds were identified which are different from the goat and sheep breeds of the world. This is the first report of the whole nucleotide of BMP15 gene in the sheep. A lot of work has been reported on these genes but total nucleotide picture in the sheep is not reported. Sequences of Bmp15 gene from sheep and goat breeds of Pakistan has been submitted to the NCBI GenBank database libraries,USA under accession numbers JN655669, JN655670, JN655671 and JN655672. It will result in fast vertical expansion of small ruminants to increase the mutton production and uplift the socio economic condition of small ruminant's farmers in the country.

Phenotypic Characterization Of Two Indigenous Chicken Ecotypes Of Pakistan

by Amjad Iqbal | Dr. Afzal Ali | Prof. Dr | Prof. Dr. Khalid Javed.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2013Dissertation note: Poultry is the second largest industry of Pakistan and a significant proportion of poultry products (meat and eggs) originates from the rural poultry production system which is an important source of livelihood for about 80% of the rural households in Pakistan. The quest for greater production through the use of exotic breeds has created difficulties for backyard production systems and is dangerous on economic, social and scientific grounds. This practice is also resulting in rapid erosion of indigenous genetic resources. The commercial sector itself may require access to indigenous genotypes as its genetic base is quite narrow and for catering the future needs industry may require improvement in many other characteristics (for instance, adaptability and disease resistance) in addition to just egg and meat yield enhancement. Unfortunately, in many countries the indigenous breeds have not been studied for their potential uses and benefits and have been indiscriminately cross bred with exotic breeds. Therefore, it is crucial to study and characterize the indigenous breeds and generate necessary information to be used in future to reap maximum benefits. The generated knowledge would provide useful information essential for conservation of indigenous genetic resources. The knowledge about the morphological attributes of native chickens has not been adequately documented on technical and scientific grounds. Keeping this in view the present study was planned and data on qualitative and quantitative traits regarding the morphology were collected on Aseel and Naked-neck chickens using a specially designed performa.All recorded data were entered in MS Excel 2010 spreadsheets. The qualitative parameters were expressed as percentages and quantitative parameters were expressed as mean ± standard error. A great variation in plumage colors and patterns was observed in both Aseel and Naked-neck chickens. The Aseel chickens possessed a pea comb whereas Naked-neck chickens possessed single comb. Also it was interesting to note that about 10% of Aseel hens possessed spurs however spurs were absent in Naked-neck females. On the basis of quantitative traits,it was found that the Naked neck chickens were smaller in size than the Aseel chickens regarding body weight (Aseel: 1938.7±36.9 g in females and 2317±98.4 g in males; Naked neck: 1160.4±19.3 g in females and 1415±22.2 in males), shank length (Aseel: 8.1±0.1 cm in females and 10.3±0.1 cm in males; Naked neck: 7.5±0.05 cm in females and 8.6±0.1 cm in males), shank circumference (Aseel: 44.2±0.5 mm in females and 52.4±1.1 mm in males; Naked neck: 36.5±0.7 mm in females and 41.4±0.5 mm in males), and keel length (Aseel: 15.1±0.1 cm in females and 16.0±0.2 cm in males; Naked-neck: 14.1±0.2 cm in females and 14.7±0.1 cm in males). The information about indigenous Aseel and Naked-neck chickens documented in the present study can be used as reference in future for conservation and breed improvement programs.
