Prevalence and management of ovulatory disturbances was recorded from 454 repeat breeding crossbred Jersey cattle of Kashmir valley during a 7 years period (2004-05 to 2010-11). Prevalence of anovulation and delayed ovulation was recorded 16.30 and 12.78% with an overall prevalence of 29.07% ovulatory disturbances. Anovulatory animals treated with RCG (Chorulon @ 1500 to 3000 IV i.v. per animal depending on body weight) showed conception rate (CR) of 86.36%; while those treated with Buserelin (Receptal @ 5ml Lv. per animal) as 100.00%, although this difference was statistically non-significant. Animals suffering from delayed ovulation inseminated twice, thrice or 4th times depending on the persistence of estrus signs showed overall CR of 87.93%.
