title: A comparative analysis on factors affecting calf mortality of buffalo in a breeding farm.
abstract: Study of calf mortality was carried out on three breeds of buffalo in a buffalo breeding and development farm. There were three types of buffalo such as Nili-Ravi, Indigenous and their crosses were reared here. Data for this study had been taken from record registrar books maintained in the farm. One hundred thirty one dead calves were studied for mortality. Pure Nili-Ravi showed higher mortality rate. The highest life span of dead calves was found as 717 days in Nili-Ravi and lowest 1 day in all breeds. The effect of breed on the life span of dead calves was insignificant (p>0.05). Furthermore, female calves are more prone to death as compared to male counterpart.
