abstract
The biotechniques in reproduction have made significant contribution in increasing the reproductive efficiency, global transport and multiplication of genetic material, and conservation of unique genetic material for use in future. Animal biotechnology encompasses the application of science and engineering principles to the processing or production of materials to provide services or goods for human use. These techniques are artificial induction of breeding characteristics in female, artificial insemination (AI) using either fresh, frozen or sexed semen, Embryo transfer using fresh or frozen in vivo or in vitro produced embryos, cloning using somatic cell nuclear transfer (SCNT) procedures and production of transgenic animals. Artificial induction of estrus involves the use of recombinant exogenous progesterone alone or together with gonadotropins. Through artificial insemination selected male can pass his merit to thousands of females. By embryo production and transfer technology we can produce more number of offspring from a superior female, in a minimum time and cloning involves somatic cell nuclear transfer procedures and production of transgenic animals.
