Reproduction is a significant factor in determining livestock productivity. The better reproductive efficiency seen from the low birth interval is expected to increase the population of buffaloes. The purpose of this research is to know the reproductive performance of productive ages of female swamp buffalo in Ngawi Regency, East Java Indonesia, including service per conception (S/C), length of pregnancy. days open (DO), birth interval, conception rate (CR) and fertility index. The material used in this research is 162 female buffalos by 40 breeders. The research method used surveys. The data obtained were analyzed descriptively. The results showed that the buffalo reproduction performances in Ngawi Regency were average service per conception (1.4 ± 0.4) times, length of pregnancy (10.4 ± 0.5) months, days open (3.8 ± 0.7) months, birth interval (14.3 ± 0.9) months, conception rate 68.5 percent and fertility index 62.6 percent. It was concluded that the reproductive performance is considered normal regarding fertility index. So that proper reproduction arrangements can increase livestock productivity both concerning production and reproduction.
