“…The supplemental rumen protected fat group showed linear increase (P<0.05) in milk fat percentage as compared to CON while difference between the supplemental protected fat group was statistically non-significant (P>0.05). Similar observations were reported by Ranjhan et al (2012), Mane et al (2016) and Savsani et al (2016). Higher milk fat in BF 100 and BF 200 might be due to availability of more fatty acids (SFA and USFA) for absorption in intestine due to protection of fat and these fatty acids are directly incorporated in milk fat after absorption from intestine, leading to increase in milk fat.…”

Objective of the study was to investigate the effect of dietary supplementation of rumen protected fat on productive performance, nutrient utilization and blood biochemical profile of Surti buffaloes. Eighteen multiparous buffaloes (2-4 lactation) in early lactation were divided in three homogenous groups of CON (control), BF100 and BF200 with six animals in each group. The animals in CON were fed with a basal diet consisting of concentrate mixture, green sorghum and paddy straw as per ICAR nutrient requirements, while the animals in BF100 and BF200 group were fed with same ration and supplemented with 0.75% (100 g/d) and 1.5% (200 g/d) bypass fat on DMI basis, respectively for 15 days pre-partum to 90 days post-partum. The dry matter intake, body condition score, milk yield and milk composition parameters like protein, lactose and SNF were not influenced by supplemental bypass fat. Milk fat percentage, production of 4% fat corrected milk (FCM), solid corrected milk (SCM) and energy corrected milk (ECM) increased quadratically with the increasing level of rumen protected fat in the diet. Feed efficiency (FCM/DMI) and energetic efficiency of milk production improved in a quadratic manner. Nutrient intake of DCP, TDN and digestibility of DM, CP, CF and NFE except EE remained statistically non-significant. The serum triglycerides, cholesterol and calcium level were higher in bypass fat-supplemented group. However, serum total protein and glucose level remained statistically at par. Thus, bypass fat supplementation at 0.75% of the DM intake (100 g/d) increased the milk fat percentage, FCM production and feed efficiency along with serum triglycerides and cholesterol level in lactating Surti buffaloes.
