Wariability in test day milk yield and milk composition at day 15 and 60 of actation in Surti and Jaffarabadi buffaloes

摘要

Surti and Jaffarabadi buffaloes 10 each maintained at Livestock Research Station, Navsari and Cattle Breeding Farm, Junagadh, respectively were selected for the study. Milk samples were collected from each selected buffalo at day 15 and 60 postpartum(pp). The data of milk yield was recorded daily till day 60 pp in both the populations. Milk composition of samples viz. protein, fat, solid not fat and lactose percent were analyzed at day 15 and 60 pp. It was observed that Jaffarabadi buffaloes produced significantly higher milk in terms of test day milk yield and fat and protein corrected test day milk yield as compared to Surti buffaloes at day 15 and 60 pp. Jaffarabadi buffaloes were also found to be superior for fat, SNF, protein and lactose content during early lactation while for fat and protein content at 60 day pp as compared to those of Surti buffaloes. SNF percent showed significantly high positive correlation with protein and lactose percent at 60 day pp milk in both buffalo breeds.
