摘要

The study was conducted on reproductive performance of Bhagnari cattle maintained under semi-intensive management condition at Usta Mohammad Cattle Farm, Baluchistan. The data was collected on eighty four adult Bhagnari cows, selected on the performance record and utilized for this study. The results revealed that the mean age at puberty was recorded as1154.179±53.48 days and age at first calving was 1462.024±59.38 days. The calving interval was recorded as 437.59±16.91 days, service period 158.71±17.01 days and postpartum estrus period 135.94±11.87 days. The mean milk yield was recorded 785.78±14.53 liters per cow, which was increased from first to 4th lactation. The calving intervals, service period and post-partum estrus was found decreased from 1st to 5th parity. The difference between the parity was non-significant (P>0.005) for calving interval, postpartum period, service period and milk yield. The reproductive performance and milk yield was found very low, which needs to be improved by improving management practices and out-crossing or cross breeding program on scientific line.
