Relationship of Blood Metabolites with Reproductive Parameters During Various Seasons in Murrah Buffaloes (Report‪)‬

INTRODUCTION Murrah is the most important and efficient producer of milk among the Indian breeds of buffalo. Bulls of this breed are used extensively for up-grading of inferior stock. The average milk yield in a lactation is 1,500 to 2,500 kg. Buffaloes have long been considered as sluggish breeders because of their inherent long calving interval (450 to 500 days), service periods (170.32 [+ or -] 4.67 days) and seasonality in their breeding despite being regular breeders (Prakash et al., 2005; Khan et al., 2009). Infertility and sub-fertility due to sub-estrous, anoestrus, repeat breeding and longer postpartum interval (PPI) and service period remain the predominant issues and challenge to researchers, scientific community and veterinarians in general and the farming community in particular.
