Estrus Synchronization Protocols for Cows
Estrous synchronization and artificial insemination (AI) are reproductive management tools available to beef producers for over 30 years. Synchronization of the estrous cycle has the potential to shorten the calving season, increase calf uniformity, and enhance the possibilities for utilizing AI. Artificial insemination allows producers the opportunity to infuse superior genetics into their ope...
متن کاملEstrus Synchronization and Conception Rate of Crossbred Cows Using Hormones
The present cattle population of Bangladesh is 24.17 million (DLS, 2009). More than 80 percent of this cattle population is indigenous and rests of them are purebreds and crossbreds of different exotic breeds (Friesian, Jersey and Shahiwal) cattle, which is contributing a major share of livestock sub-sector and playing multi-functional roles (supply of milk, meat, skin, manure, carting etc.) in...

Although hormonal treatment of heifers and cows to group estrous cycles has been a commercial reality now for over 30 years, beef producers have been slow to adopt this management practice. Perhaps this is because of past failu...
متن کاملComparative efficacy of different estrus synchronization protocols on estrus induction response, fertility and plasma progesterone and biochemical profile in crossbred anestrus cows
AIM To evaluate estrus induction response and fertility including plasma progesterone and biochemical profile following use of three standard hormonal protocols in anestrus crossbred cows. MATERIALS AND METHODS The study was carried out on 40 true anestrus and 10 normal cyclic cows. 10 anestrus cows each were treated with standard intravaginal controlled internal drug release (CIDR) device, O...
