Abstract: Thirty-six indigenous postpartum cows were given dry straw ad libitum + 1.5 kg concentrates (control) or UMS ad libitum + 1.5 kg concentrates (treated). Cows were stall fed. Calves were tied up at night and allowed to free access or suckling to the cows during the whole day. The cows were milked only in the morning. Live weight change of cows and calves were recorded monthly and milk yield was recorded daily. The reproductive performance of cows was also studied. Live weight change of cows -57.40 and 37.75 g/d (P < 0.05); milk yield of cows 1.83 and 2.52 kg/d (P < 0.01); calf weight gain 96.99 and 139.35 g/d (P < 0.01); calving to first service interval 182 and 113 days (P < 0.01) ; calving to conception interval, 210 and 134 days (P < 0.01) and number of services per conception 2.11 and 1.94 (P >0.05), for controlled and treated groups respectively. It is concluded that UMS can be fed for improving the productive and reproductive performance of indigenous cows under the village conditions of Bangladesh.
