摘要：

We evaluated records of reproductive management Jaffarabadi buffalo breeds, Murrah, Mediterranean, Carabao and Baio types, and their crosses, in the period from 1983 to 2005. We studied the following reproductive characteristics: Age at first calving (mean 1052.52 +/- 120.45 days), calving interval (399.69 +/- 23.78 mean days), Reproductive Efficiency (average 91.09 +/- 1,89%), Real Adapted Fertility (average 29.30 +/- 4.40kg calf calved each year), the First Labor Productivity Adapted (mean 33.75 +/- 6.89kg) and Accumulated Productivity Adapted (mean 22.86 +/- 6.55kg calf calved each year). Influences were observed in the year of delivery and degree of blood on the female traits, suggesting that such effects should be included in genetic evaluation and selection of animals. The production indices used were of great value for the selection, and should be well studied for their interactions with the overall performance of the herd.
