Abstract: This experiment was conducted at Buffalo Breeding and Development Farm, `Bagerhat` a southern district of Bangladesh to investigate the milk (lactation) yield, lactation length and calf mortality rate of Nili-Ravi and crossbred buffaloes. From this study it was revealed that the average milk yield per lactation of Nili-Ravi and crossbred buffalo cows were 1161.805?684.07 and 696.636?258.68 liters respectively, while their average milk production per day were 3.5 and 2.24 liters. On the other hand average lactation length for same genotypes were 330.426?70.08 and 311.556?74.14 days respectively. The overall calf mortality rate was 24.28% and the average calf mortality rate for Nili-Ravi and crossbred buffalo were 37.1 and 14.1 percent respectively. Statistical analysis showed that there were significant variation (p<0.01) existed between Nili-Ravi and crossbred buffalo calves in respect of calf mortality. From the study it may be concluded that Nili-Ravi buffaloes are better than crossbred buffaloes considering specially on milk production mentioned in the Buffalo Breeding and Development Farm, Bagerhat, Bangladesh.
