Popis:	The objective of this study was to determine the effect of bull exposure after calving on postpartum interval to estrus, in Nili-Ravi buffalo. Buffaloes were divided into 4 groups; BEC & BEI; exposed continuously or intermittently to the physical presence of bull, EPB & NE; exposed or not exposed to discharge waste (urine & feces) of bull. Buffaloes were exposed on d 5 after parturition. Postpartum interval to first behavioural estrus was shorter in BEC than BEI, EPB and NE treatments. The mean serum progesterone concentration did not differ significantly between BEC and other (BEI, EPB and NE) treatments. It was concluded that presence of bull has positive effect in reducing calving interval in Nili Ravi buffalo.
