Abstract :

Rapid propagation of livestock with higher production potential is the need of hour to meet the demand of feeding burgeoning population of the world. Adopting reproductive biotechnological tools like in vitro embryo production, ovum pick up, somatic cell nuclear transfer/cloning, preantral follicle technology, transgenic animal production etc., will help in the faster multiplication of high producing livestock. Application of techniques like transgenic animal production will also help in production of important biological substances of human importance like human lactoferrin in milk of the transgenic cows. To take the technology of in vitro embryo production and embryo transfer to the farm level in developing countries, a major hindrance has been the cost factor. In order to economize the production of in vitro embryos, expensive inputs like Follicles Stimulating Hormone (FSH) and Fetal Calf Serum (FCS) have successfully been replaced with Pregnant Mare Serum Gonadotropin (PMSG) and steer serum, respectively. Ovum pick up (OPU) technology provides a continuous supply of high quality oocytes from elite cows with assured genetic merit for the production of high yielding cows. Trans-vaginal ovum pick up using ultrasound facilitates two sessions of ovum pick up in cattle and buffaloes. One more technology that can supply higher number of oocytes is preantral follicle technology. Though offspring could not be produced using this technology in farm animals, embryos could be produced from pig, sheep, goat and buffalo during the last decade. These reproductive technologies turn around the livestock production in developed countries, however the success rate and cost factor are prohibitive for adopting them in developing and poor countries.
