Buffaloes are hardy animals that can survive under rough condition and are known to be a slow breeder. Their poor reproductive performance has contributed to the reduction of ovulation, declining in the reproductive performance and thus affecting the calving rates. Therefore this study is conducted to assist in the improvement of breeding performances in swamp buffaloes in terms of pregnancy rates. A total of 30 female Swamp buffaloes were selected based on the predetermined criteria. They were divided into two groups and synchronised with Ovsynch. Group 1 (G1) were kept together with a bull for five days to allow natural mating while Group 2 (G2) were artificially inseminated using fresh semen from a bull in the same herd. Throughout the experiment, a total of four buffalo cows were excluded from G1 and G2. Pregnancy Diagnosis performed 45-60 days post mating showed that 23.1% (n=26) of the animals were pregnant with 50% (n=12) of females in G1 were pregnant and no pregnancy detected in the females in G2. Pregnancies were observed in females aged above four years old weighing about 350 kg and had at least calved once before. These may contribute to the difference in the outcome of the study as all female in G2 were still heifers when they were selected. Further studies are needed to be done to achieve a better reproductive performance of the swamp buffaloes.
