Abstract:
The present study was carried out to determine the conception rate (CR) and sex ratio of artificial insemination using sex-sorted semen in Indigenous cattle and buffaloes. The study was conducted by various cattle development centers operated by BAIF institute for sustainable livelihoods and development (BISLD), Maharashtra from April 2019 to March-2022. The overall CR was 44.88% and the sex ratio of female over the male was 91.14 from a total of 8,963 insemination records. Highest CR was observed in buffaloes 45.18% while in cattle 44.62% and sex ratio of female over the male is 91.68% in cattle while 90.56% in buffalo. Amongst buffaloes, Murrah showed the highest CR (45.29%) than Jaffrabadi (44.50%). Amongst Indigenous native cattle breeds, the CR in Sahiwal, tharparkar, Khillar and Gir were 45.67, 44.46, 44.20 and 43.79%, respectively. Similarly CR in Khillar sex-sorted semen using Y-chromosome bearing sperms was found to be 45.50% with the sex ratio of male over female 90.82% from a total of 478 followed insemination records. The success observed with the use of sex-sorted semen boosted confidence to artificial insemination technicians and farmers for adaptation of sex sorted semen technology and also opportunity could be made available for faster multiplication of progenies with desired sex. Application of sex sorted semen in the breeding of indigenous cattle and buffalo would also help to protect endangered species.
