The combined effects of prilled fat and yeast culture (YC) mixture supplementation were investigated on the production performance and economics in 18 early lactating Murrah buffaloes. Buffaloes were divided into two groups as control group (CON group) and supplemented group (SG). CON group was fed wheat straw, maize fodder and concentrate mixture, while SG was supplemented additionally with 100g prilled fat and 25g Saccharomyces cerevisiae (SC)/day from -21day prepartum to 90 days postpartum. The effect of feeding on persistence of milk production was monitored up to day 120 of lactation. Milk yield was increased (p<0.01) by 18.94% in SG than the control group (11.93 vs. 10.86 kg/d). However protein, solid-not fat (SNF) and lactose contents were not influenced. Milk fat yield increased (p<0.01) by 6.16% in SG than the CON. Body weights, body condition score and DMI were improved (p<0.01) and Somatic cell count (SCC) was decreased (p<0.05) in SG as compared to CON group. The feeding supplement produced noticeable changes in the fatty acid profile in milk fat. Saturated fatty acids (SFA) decreased by 12.18% and unsaturated fatty acids (USFA) increased (p<0.01) by 30.14% in the SG buffaloes. However withdrawal of feeding declined milk production (p<0.01). The lowered ratio of SFA: USFA indicated beneficial effects of feeding on fatty acid profile of milk for human consumption. It was concluded that prilled fat and S. cerevisiae feeding effect was galactopoietics in nature by increasing milk yield and fat. The feeding generated an additional income of 117 INR/animal/day.
