Protocolos de sincronización de celos en vacas Bos Indicus

Abstract

Thee strus synchronization protocols in cows Bosindicus. This research was performed to know everything about the timing and hormonal manegment of estrus cow. The problem is that BosIndicus cows are animals with low reproductive parameters due to poor heat detection, postpartum, estrus at night, etc. Therefore, one of the objectives is that the protocols for synchronization of estrus in cows Bosindicus allows to regulate thehormonalovariancyclicity, which is consideredone of the alternativesto improvethese featuresofthe estrus cycleand behaviorof Bosindicus winning that allowbetter growth performance and reproductive, thus eliminating the timeand laborrequired todetect heat, given that asuccessfulprotocolfor beef cattlenecessary to monitorfollicular development andcorpus luteum regression. The useof prostaglandinsallowed to register86.5% ofconception, being superior to the restofestrus synchronizationprotocolsMexican, J.(2009), reportsfollowed by;CIDR. Towith which76% was reached, while with the othermethods of synchronization as:COSYNCH, OVSYNCH, and SELECTSYNCH were 40-50%, 45-50% and 44%, still lower than the initially cited. Thus, we conclude that the estrus synchronization protocols help to express their external manifestations of jealousy, but this one insemination at the right time especially in herbs detection is poor, or unreliable should implementprotocoltimed artificial insemination (IATF).
