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 Protocols for Heifers
Estrus synchronization and artificial insemination (AI) remain the most important and widely applicable reproductive biotechnologies available for cattle (Seidel, 1995). 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 کاملEstrus induction and fertility response following different treatment protocols in Murrah buffaloes under field conditions
AIM The aim of this study was to evaluate the efficacy of three different treatment protocols for estrus induction and conception rate in postpartum anestrus buffaloes during breeding season under field conditions. MATERIALS AND METHODS The 47 postpartum anestrus buffaloes of the 2nd to 6th parity were divided into three groups. Group 1 (n=16): Buffaloes received cosynch treatment, that is, b...
متن کاملFollicular Dynamics Following Estrus Synchronization in Swamp Buffalo Cows (Bubalus bubalis)
The objective of this study was to elucidate ovarian follicular dynamics in swamp buffalo cows (Bubalus bulalis) following a protocol for estrus synchronization during hot as low breeding season (March to June) and cool as high breeding season (November to February). Nine pluriparous buffalo cows received a progesterone ear implant for 10 days together with the administration of a luteolytic do...
متن کاملPharmacological Control of Estrus in Tropical Cattle, an Economical Assessment of Different Synchronization Protocols
To compare the fertility results and to assess the cost-effectiveness of several synchronization protocols applied under the conditions of beef cattle enterprises in Colombia, 1658 multiparous zebu crossbred cows mostly Brahman and Nelore ranging between 2 6 parities were used. Five protocols of pharmacological treatments varying in hormones used, dosage and the time of application were tested....
