Application of transgenic animals in animal production and health

The progress in Recombinant DNA technology guided the way for production of transgenic plants and animals. The production of Bt cotton and Bt brinjal was one of them. Transgenic cows capable of producing human proinsulin and human lactoferrin in milk have been successfully engineered. Though the efficacy of the techniques used or such transgenic organism is questionable, with the creation of new and better technology like the clustered regularly interspaced short palindromic repeats (CRISPR)-associated protein system, the chances and effectiveness for success of gene incorporation during development of a transgenic animal has increased. In near future such transgenics are going to play an important role in support and sustenance of human society. This review deals with the application of transgenesis for enhancing productivity and promoting better health in animals and humans alike.
