The objective of this study was to evaluate the current feeding situation and reproductive performance of Brahman crossbred cows bred with Charolais, Droughtmaster and Red Angus semen at smallholders in Quang Ngai province. A total of 90 households with Brahman crossbred were evaluated for cow feed and feeding situation. In addition, 373 Brahman crossbred cows were used to evaluate the reproductive performance, in which 127 cows were inseminated by Charolais, 120 by Droughtmaster and 116 by Red Angus. The results showed that the dry matter (DM), crude protein (CP) and energy (ME) intake of Brahman crossbred cows were not different (P >0.05) and independent from being bred with Charolais, Droughtmaster or Red Angus. The amount of DM, CP and ME intakenby the pregnant cows was 6.9-7.5; 0.6-0.7kg/day and 14.6-15.5Mcal/day, respectively, and 3-month after calving was 7.5-7.6; 0,7kg/day and 15.5-15.9Mcal/day respectively. The calving interval of Brahman crossbred cows bredwith Charolais, Droughtmaster and Red Angus semenvaried between 394-397 days (P >0.05). Further studies should be done on the growth and performance of the progeny of the crosses between Brahman crossbred cows and Charolais, Droughtmaster and Red Angus bulls.
