Abstract

Data on 430 artificially inseminated and 257 naturally bred cows was used to determine the service period and calving interval. Combined together the service period mean = S. E. was calculated to be 160.5 = 3.55 and calving interval (mean = S. E.) to be 400.88 = 5.64 days. The service period and calving interval for the artificially inseminated cows were 152.73 = 4.74 and 387.24 = 7.50 days respectively. The corresponding values for naturally bred cows were 182.45 = 3.80 and 423.69 = 8.11 days respectively. The artificially inseminated cows had shorter service period and calving interval. The possibility to reduce service period and calving interval 1st discussed.
