This livestock sector has been contributing considerable portion to the economy of the country and still promising to rally round the economic development of the country. The total cattle population for the state is estimated to be about 16.2 million. Out of this the indigenous cattle constitute about 13.1 million and the remaining 3.1 million are crossbred cattle and80.86 per cent of the total cattle in the state are local breeds and remaining are crossbred and exotic breeds that accounted for about 19.13 per cent ,respectively (Anonymous, 2015).As per 19th Livestock Census-2012, bovine population in Maharashtra has declined by about 5 per cent to 2.1 crore as against 2.2 crore in 2007. While crossbreds cattle increased by 19 per cent, local cows and buffaloes have shown 8- 9 per cent decline. However, the indigenous cattle and buffalo milch population declined by 5-7 per cent between 2007 and 2012, while there has been an impressive growth of26 percent in crossbred milch animals. International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 3 (2020) Journal homepage: http://www.ijcmas.com Data on 57000 Artificial Inseminations (A.I.) performed at field level during 5 years (from January 2010 to December 2014) on 30998 animals owned by 8063 farmers of Beed district and 6903 farmers of Jalgaon district of Maharashtra state were considered for study. Overall mean conception rate as 47.33±0.32 per cent. The conception rate was significantly affected by area, year of A.I., heat stage, body condition, AI sequence number. However, season of A.I., lactation number and economic condition of farmer did not significantly influence the conception rate.
