Abstract : Thirty big size buffalo bulls and 900 cows were selected from 220 local bulls and 1,280 local cows through body weight, size, conformation and reproductive performance in 4 communes of Ha Giang province for improving the body weight and growth of local swamp buffalo. Selected bulls were 20% higher than average of the herd in body weight. Buffaloes were divided into 30 groups (1 bull and 30 cows each). Cows were detected estrus every day and mated within group. Birth weight of calves was 23.23 kg for male and 22.18 kg for female. The expected body weight at 3, 6, 12 and 24 months of age were 57.4; 84.3; 148.1 and 246.0 kg for male and 54.8; 82.6; 144.5 and 242.7 for female, respectively. It is concluded that selection of big size bulls with 20% body weight higher than average of herd improved the body weight and growth of calves. Selection of buffalo bulls and cows (especially bulls) should be applied in buffalo production annually; this is a good solution for improving the body size and productivities of local buffaloes.
