Transgenic animal technology: Technique and its application to improve animal productivity

Abstract

The live stock improvement and commercial exploitation of genetically altered animal for the production of useful recombinants are major goal in animal biotechnology. The presence of foreign genes in animals are called transgenic and animals with manipulated genetic material are known as transgenic animals. Transgenic technology provides a method to rapidly introduce new genes into animals without cross breeding the transgenic animals can be used as bioreactors for the production at important drugs and other chemicals several transgenic farm animals such as cow, sheep, cattle etc, can be effectively exploited for the production of therapeutic proteins secreted into the milk in mammary Gland. Genetic manipulation of animals offers significant contribution in understanding mammalian gene expression, combating diseases, gene therapy etc.
