Abstract

Eighteen lactating Murrah buffaloes were divided into three groups (control, T1’ T2) of six each to study the effect of prill fat and rumen-protected choline supplementation on fatty acid profile in the milk of lactating Murrah buffaloes. Buffaloes in all three groups were fed a similar total mixed basal diet, which consisted of green fodder and wheat straw. Concentrate mixture was given according to the level of milk production to meet the maintenance and milk production requirements. Buffaloes in Group T1 were supplemented with prill fat @ 2.5% of total DMI per buffalo per day and while buffaloes in GroupT2 were supplemented with prill fat @ 2.5% of total DMI per buffalo per day and 54 g rumen-protected choline in their basal ration. Both the T1 and T2 groups had higher levels of unsaturated fatty acids, with the T2 group having a significant increase. The concentration of monounsaturated fatty acids increased significantly in group T2, but there was no change in polyunsaturated fatty acid concentration. Short-chain fatty acid concentrations were found to be higher in groups T1 and T2 than in Control, but the difference was not significant. Long-chain fatty acids were found in higher concentrations in T1 and T2 than in Control, and the increase was significant. The palmitic acid concentration was higher in animals in group T2 (32.470.51 g/100 g fat). Oleic acid was the most significant contributor to unsaturated fatty acids, while palmitic acid was the most significant contributor to saturated fatty acids.
