Abstract: Reproductive performance and timing for AI is depend on intensity of oestrus. Irregularity in the manifestation of oestrous behaviour can complicates the reproductive efficiency. In the present study fifty postpartum anestrous crossbred cows were selected based on history, clinico-gynaecological examination and ultrasonography. The animals were divided into four treatment groups and treated with ovsynch, ovsynch fortified with minerals and bypass fat, kisspeptin and kisspeptin fortified with minerals and bypass fat, respectively. Most of the animals responding to treatment showed intermediate oestrus behavior in all the treatment protocols. However, Kisspeptin with or without fortification lead to delayed ovulation and prolonged oestrus with a dose rate of 1.3mcg/kg in the treatment of postpartum anestrous.
