摘要

A total of three hundred and seventy five postpartum crossbred cows were divided into three groups viz group I, II and III. Group I animals (n=180) were treated with PGF_(2alpha) after palpation of corpus luteum. Group II animals (n=155) were treatedwith CIDR (Controlled Internal Drug Release Device). Group III animals (n=40) were treated with ovsynch protocol. Fixed time artificial insemination was performed in the responded animals. Percentage of induced estrus and mean onset of induced estrus were 71.11,83.20, and 67.50 and 58.8,44.4,53.4 hrs in group lf II and III respectively. First service conception rate was 52.20, 42.74 and 55.55 per cent in group I, II and III respectively. From this study it may be concluded that Ovsynch treated crossbredcows gave better fertility rate compared to PGF_(2alpha) and CIDR treated cows.
