Abstract
An on farm study has been carried out to evaluated pregnancy rate and estrus responses to treatment of crossbred animals and buffaloes with estrus synchronization protocols. Animals belonging to both the species were selected at random, irrespective of parity, milk yield and body weight. The estrus synchronization protocols were evaluated. Treatment included an injection of receptal @ 2.5ml followed by lutalyse @ 5.0ml im and fixed time artificial insemination (FTAI) was done 16-24 hr after second dose of receptal @ 2.5ml im injection.
