Abstract:
India tops the livestock population in the world. Total livestock population in the country is 535.78 million showing an increase of 4.6% over Livestock Census-2012-the largest in the world. This is mainly because of recent advancements in frozen semen technology in India. With the advent of fluorescent microscopy, flow cytometry and advances in molecular biology, now it has become possible to evaluate the spermatozoa in terms of specific functions that are well related to fertility. However the emphasis on production of female calves is gaining popularity with a view to control the male calves’ population. Fluorescence-activated cell sorting (FACS) and immunological method of semen sexing are the two commonly used sexed semen technologies. This article provides a concise review of progress in the advancements of frozen semen technology in India along with pioneer work carried by scientists in field of animal reproduction and breeding.
