摘要：
This trial was conducted to study the effects of daily milking frequency on milk yield, duration of lactation, incidence of mastitis, and calves body weight gain. Sixty-three crossbred Holstein-Zebu cows were equally and randomly assigned to three experimental groups according to the frequency of daily milkings as follows: once a day milking, twice a day milking, or alternating once or twice a day milking every 14 days. The duration of lactation, mammary gland health. and calf production did not differ among treatments in this study. However, cows milked twice a day yielded 24.54% more milk per lactation (699.9 kg) compared to the other milking regimes.
