This study aimed to examine the postpartum estrous of Brahman Cross (BX) cows inseminated with a Limousine straw on smallholder farms. Ten BX cows were about five years old with a bodyweight between 365-430 kg in the last month of pregnancy was used in this study. Observations started from nine months of pregnancy until the first estrous after partus. The parameters observed included bodyweight at calving, bodywight every month during lactation to the first estrous, and duration between calving to the first estrous. The results showed the body weight at the last month of pregnancy was 410 ± 0.23 kg/head, the bodyweight immediately after calving was 384 ± 0.22 kg, the bodyweight at the first month of lactation period was 369 ± 0.22 kg, the second month was 361 ± 0.22 kg, and the body weight at the postpartum estrous was 354 ± 0.22 kg. The daily bodyweight changes after calving were -0.56 ± 0.10 kg/day, -0.23 ± 0.34 kg/day and -0.24 ± 0.22 kg/day, respectively. Postpartum estrous occurred 120 ± 1.4 days after calving. This research concluded that postpartum estrous Brahman Cross on smallholder farmer's level was relatively good and produced calf with a good body weight.
