Factors affecting service period and calving interval in Friesian X Sahiwal crossbreds



Factors affecting service period and calving interval in Friesian X Sahiwal crossbreds



Indian Journal of Animal Sciences 58(8): 986-987



Data were collected on 874 cows from 1974 to 1983. There was significant variation in service period between cows from different farms with different management and climatic conditions. First service period and 1st calving interval averaged 129.5 and 428.7 days resp. Percentage of Friesian inheritance (50, 62.5 and 75) and year and month of calving had no significant effect on service period or calving interval.
