Transgenic or Genetically Modified Farm Animals and their Applications: A ReviewBy Manoj Kumar, Poonam Ratwan
Abstract: Abstract Transgenic are genetically modified organisms having DNA from different source introduced into their genome. Genetic alteration of livestock species is advantageous to human health as important pharmaceutical proteins can be produced in economic and efficient ways. Transgenic animals like mice, rat and hamster etc. are also used to study human diseases. Transgenic livestock species comprised of different kinds of animals are modified with the purpose of improving economically important …

Influence of Environmental Factors on Performance Traits in Murrah Buffaloes: A ReviewBy Manoj Kumar, Poonam Ratwan, C.S. Patil
Abstract: Abstract Murrah buffaloes are the most important milch buffalo breed in India with superior genetic potential and has been used quite extensively for upgrading local stock to improve performance of nondescript buffaloes throughout the country. The success of Indian dairy industry is much dependent on production, reproduction and functional traits of Murrah buffaloes. Performance of these traits in Murrah buffaloes are generally affected by environmental or non-genetic factors such as …

Strategies to Minimize Heat Stress in Broiler and Layer ChickensBy Manoj Kumar, D.S. Dalal, Poonam Ratwan, A.S. Yadav
Abstract: Heat stress is one of the most important thermal environmental factors challenging broiler and layer production throughout world. Negative effects of heat stress on broilers and layer production range from reduced growth and egg production to reduced egg quality. Heat stress is more in chickens with high production performance and more feed conversion efficiency. Prolonged exposure to hot weather will lead to imbalance of acid-base equilibrium in body, decreases blood …

Heterosis–Genetic Basis and Utilization for Improvement of Dairy Cattle: A ReviewBy Manoj Kumar, Poonam Ratwan, Anil Kumar
Abstract: The phenomenon in which progeny of crosses between inbred lines or purebred populations are better than the expected average of the two populations or lines for a particular trait is known as heterosis. Utilization of heterosis is the main goal of crossbreeding. The amount of heterosis maintained in a herd depends on the type of crossbreeding system selected for breeding. Heterosis includes greater viability, faster growth rate and greater milk …

Genetic Variability and Significance of STAT Gene in Dairy AnimalsBy Manoj Kumar, Poonam Ratwan
Abstract: Abstract Importance in the bovine signal transducer and activator of transcription (STAT) gene has increased due to involvement of STAT1 in the development of the mammary gland and regulating the transcription of genes involved in milk protein synthesis and fat metabolism in lactating dairy animals. Signal transducer and activator of transcription gene are a family of cytoplasmic proteins that are stimulated in response to a large number of growth factors, …

Laboratory Animals: Usages in Genetic ResearchBy Manoj Kumar, Poonam Ratwan, Vikas Vohra
Abstract: Laboratory animals are one on which advanced research is conducted and validated in labs for better understanding the natural phenomenon of biological system, genetics and disease models. Laboratory animals include mice, rat, hamster, guinea pig, gerbil, monkey etc. Lab animals play a vital role in biomedical research and genetic studies as they share common physiology and genetics, which resemble to a large extent with humans and thus make them excellent …

Significance of TE Domain and Genetic Variations in FASN Gene in Dairy AnimalsBy Manoj Kumar, Poonam Ratwan, Uday Kannegundla, Vikas Vohra
Abstract: The interest in the bovine fatty acid synthase (FASN) gene has increased during the last few years. FASN is a multifunctional enzyme that catalyzes de novo biosynthesis of long-chain saturated fatty acid, and alteration of this enzyme may affect economic traits including fatty acid composition. FASN is involved in fat metabolism and is an important candidate gene affecting fat composition of milk because of its central role in de-novo lipogenesis …
