Reproductive efficiency is of critical importance in the dairy industry. Repeat breeding in cattle is a common reproductive inefficiency faced by dairy farmers, which leads to serious economic losses in terms of milk production and lower calf crop. Suprabasal concentration of progesterone at estrus is thought to be an important contributing factor for repeat breeding. Estrus synchronization using progesterone based protocols has been essentially used in cattle. This On Farm Trial (OFT) was carried out to study the effect of administration of progesterone in the form of a transdermal cream in the induction of estrus in dairy animals. The overall proportion of dairy cattle that evinced estrus after treatment with transdermal progesterone cream was 82.5%. Among these, cattle that evinced estrus after 72 hours of treatment was 76.92%, out of which 30% were found pregnant at 60 days post insemination. Remaining 23.08% of the animals evinced estrus within 72 hours of treatment and all of them were found pregnant at 60 days post insemination.
