    53. PROGRAMAS DE SINCRONIZACION

    54. PROGRAMAS DE SINCRONIZACION MEJORAN LA EFICIENCIA REPRODUCTIVA The two most important management factors relating to reproductive performance are heat detection and conception rates The time required to detect estrus is reduced, which in turn decreases labor expense associated with the breeding program. Tjey concentrate estrus activity in a herd and facilitates artificial insemination.

    55. PROGRAMAS DE SINCRONIZACION

    56. PROSTAGLANDINAS All cows eligible to be rebred after calving are palpated. Cows with a functional CL are injected with prostaglandin and observed for heat. Cows without a CL, and those that were not observed in heat following the initial injection are examined again at the next veterinary visit. The system continues on a routine, ongoing basis with every cow remaining on the program until diagnosed pregnant. Pregnancy checks should be conducted 35 days after insemination. The value of examination is not necessarily related to pregnancy diagnosis, but rather to identifying cows not pregnant and increasing the likelihood that these cows could be inseminated at the next heat. Cows not pregnant can be included with the prostaglandin group or identified as cull cows. Permits heats to be concentrated within a few days Permits groups of animals to be chosen which are ready for inseminationAll cows eligible to be rebred after calving are palpated.

    57. DISTRIBUCION DE CALORES TRATADAS vs NO TRATADAS Distribution of heats in 727 cows treated with prostaglandin. For comparison, without treatment, heats are distributed evenly over a 21-day cycle (100/21 = 4.7% per day). Distribution of heats in 727 cows treated with prostaglandin. For comparison, without treatment, heats are distributed evenly over a 21-day cycle (100/21 = 4.7% per day).
