Abstract
The profitability and the intensity achieved by the genetic improvement is determined by the reproductive performance of the farm animals. The major cause of economic loss is reproductive inefficiency in the livestock sector. In the past few years, several advances have been made in reproductive technologies (RTs) to increase the efficiency of genetic improvement. These technologies include Artificial Insemination, Sexed semen Technology, Cryopreservation, Multiple Ovulation and Embryo Transfer, In-vitro Embryo Production (IVEP), Transgenesis etc. The problems of infertility of male or female, postpartum infertility in high-yielding animals of high genetic merit individuals and breeding of distant species has been overcome through these technologies. The inclusion of these techniques in animal breeding had made possible to obtain large number of progenies from genetically superior animals. This review, discuss the various innovative reproductive technologies implemented in livestock sector.
