This experiment was conducted to study the effect of supplementing Ca salts of soya acid oil fatty acids on milk production, its composition and nutrient utilization in lactating buffaloes. Lactating Murrah buffaloes (16) were divided in 2 groups (milk yield 7.08, 6.92 kg/d; 30 and 25 days in milk, 2_4 lactation) of 6 animals in each group, and the animals in control group were fed with wheat straw, green maize fodder and concentrate mixture as per requirements and the animals in experimental group were fed with the same ration as that of control group along with 4% Ca salts of soya acid oil fatty acids of total DMI for 90 days. The average milk yield in experimental group was higher by 12.43% over that of control group. Similarly, the 4% FCM yield was higher by 13.40% in experimental group over that of control group. There was no difference in milk protein, total solids and solid not fat in both groups except milk fat content which was higher in experimental group than that of control group. The total LCFA and MUFA content in milk fat was higher in experimental group compared to control group. The DMI and CPI were similar in both groups, whereas TDNI was higher in experimental group than that of control group. The digestibility coefficient of DM, CP, CF, NDF and ADF were similar in both groups except EE which was higher in experimental group than that of control group. It could be concluded that supplementation of Ca salts of soya acid oil fatty acids at 4% of DMI improved milk yield and proportion of unsaturated FA and LCFA in milk fat in Murrah buffaloes.
