The present study on Murrah buffaloes was conducted at Cattle and Buffalo Farm (Livestock Production and Management Section), ICAR-Indian Veterinary Research Institute. Reproductive data pertaining to post partum interval to estrus (PPIE), service period (SP), number of services per conception (NoS/C) and breeding efficiency (BE) were recorded and analysed to examine the effects of pre-partum body condition score, lactation order, age at calving, season of calving, body weight at calving and dry period on various reproductive traits. Age at calving, season of calving, Body weight at calving and dry period had significantly influenced the reproductive parameters like service period, post partum interval to estrus and breeding efficiency while, the factors did not show any significant effect on number of services per conception. Hence age, season and body weight at calving could be considered as indicative parameters and used as a tool to modify the management while aiming for the improvement of reproductive traits in tropics.
