Abstract

The sexed semen technology is a breakthrough technology for sorting of X and Y bearing chromosome to produce progeny of a desired sex with 80–90% accuracy. Among several methods of sorting X and Y bearing semen, flow cytometry is the best method, as it doesn’t changes more sperm morphology. The sexed semen technology has several advantages like production of more female calves and more milk, lowered risk of dystocia, increased efficiency of progeny testing (PT), embryo transfer and in-vitro fertilization program. However, involvement of high cost and reduced conception rate with sexed semen are the major hurdles in adoption of this technology. In India, first male calf named Shreyas was born on 1st January, 2011 using sexed semen. After that predetermined sex of female as well as male calves were born. Sexed semen with proper management practices on dairy farms will help to grow herd internally with improved traits of female calves. Thus, with more organized dairy farming, the demand for sexed semen is expected to rise in near future.

性别精液:印度奶牛养殖业的福音

性别化精液技术是一项突破性的技术，可以对携带X和Y染色体的染色体进行分类，以达到80-90%的准确率产生理想性别的后代。在几种分选携带X和Y染色体的精液的方法中，流式细胞术是最好的方法，因为它不会改变更多的精子形态。性别精液技术具有生产更多的雌性小牛和更多的乳汁，降低难产风险，提高后代检测(PT)效率，胚胎移植和体外受精计划等优点。然而，高成本和低受孕率是采用该技术的主要障碍。在印度，第一只名为Shreyas的雄性小牛于2011年1月1日用有性精子出生。在那之后，预定性别的雌性和雄性幼崽出生了。在奶牛场适当的管理措施下，有性别的精液将有助于提高雌性小牛的性状。因此，随着更有组织的奶牛养殖，对性精液的需求预计在不久的将来会上升。关键词:性别化精液，流式细胞术，X和Y染色体，精子性别化，乳制品性别精液:印度奶牛养殖业的福音。研究与评述:乳品科学与技术杂志。2017;6 (1): 10-16p。
