Variation in milk constituents during different parity and seasons in Murrah buffaloes

摘要: The characteristics of lactation curves and effect stage, parity season on milk yield level its constituents were investigated in 100 buffaloes varying from parities 1 to 7 at institute farm. Average length overall experimental animals was 323 days. Milk yield,% fat, protein lactose varied 4.3 9.5 kg, 7.19±0.04 8.63±0.07g%, 3.46±0.01 3.56 g% 4.36 4.60% respectively. Effect stage yield, fat content significant. did not vary significantly over the stages lactation. Lactose increased up sixth month lactation, however, change significant thereafter. declined during late with a concomitant increase fat. Content remained least variable constituents. study revealed that trend variation major entire comparable cows. Level decreased by 9% hot humid months due summer stress 10.6% winter present study. winter. levels more advance indicating composition. Data important phenotype indices for developing genomic selection programme buffaloes.
