摘要： Objective of this study was to investigate the effect of beer lees and cassava residues respectively substituting for soybean meal and grassiness on milk performance in lactating water buffalo. Sixteen healthy water buffaloes of early lactation were selected and randomly divided into two groups (8 each) on the base of species, parity and milk yield. Water buffaloes in control group were fed with a basal diet consisting of concentrate mixture, beer lees, cassava residues and grassiness as per requirements. Water buffaloes in treatment group were fed with the diet of beer lees substituting for soybean meal at ratios of 50% (DM basis) and cassava residues substituting for grassiness at ratios of 12.5% (DM basis). The study was conducted for 56 days after the adaptation period of 2 weeks. There was no significant effect on milk yield and feed intake of lactating water buffalo in treatment group. The milk protein, milk fat, total solids and solid not fat were higher (P<0.05) by 5.72%, 11.78%, 6.85% and 4.11% in treatment group than control group, respectively. The contents of C16:0 and C16: 1 in milk fat were higher (P<0.05) by 28.96% and 30.84% in treatment group than control group, respectively. There was an increase in the contents of C18:0, C18: 1 and cis-9 trans-11 Conjugated Linoleic Acid in milk fat of treatment group. In summary, there was no significant effect on milk performance of lactating water buffalo in treatment group of beer lees and cassava residues respectively substituting for soybean meal and grassiness, whereas milk quality was improved.
