An experiment was conducted in early lactating buffaloes for the period of 3 months in Jadakheria and Polisimal village of LimkhedaTaluka in Dahod district of Gujarat to assess the effect of supplementation of bypass fat on milk production, composition, body weight change and economic efficiency. Forty buffaloes in their 2nd and 3rd lactation were equally divided in completely randomized design in two groups according to their milk production and body weight, control group ‘CON’ was fed with a basal diet without bypass fat and treatment group ‘BYFAT’ was supplemented with bypass fat (Ca salt of palm oil fatty acids) at 20 g/kg milk yield. Fortnightly body weight changes, feed intake, milk production and composition were recorded for individual animal. The result revealed that the average daily milk yield and 6% fat corrected milk (FCM) was significantly (P<0.01) increased in BYFAT group compared to CON. Milk fat percent and fat yield was increased (P<0.001) due to feeding of bypass fat than control diet. There was significant (P<0.001) decrease in body weight loss in BYFAT group compared to control. The receipt for sale of milk was significantly (P<0.001) improved in bypass fat supplemented buffaloes compared to control animals. Feeding of bypass fat significantly (P<0.01) improved net returns on sale of milk.
