Abstract

With an objective to study vegetable oils supplementation on nutrient utilization and ruminal fermentation, 24 multiparous lactating Surti goats were divided into four groups as basal diet supplemented with no oil (CON), 3% of DMI soybean oil (SBO), 3% of DMI of rice bran oil (RBO) and equi-proportional blend of 1.5% of DMI of soybean oil and rice bran oil each (SRBO). DM, CP, NDF and ADF intake (g/d) and their digestibility (%) remained statistically similar amongst dietary treatments groups, except EE which was significantly improved in all the oil supplemented groups as compared to control. Nitrogen balance of experimental groups remained unaffected and all the animals were under positive nitrogen balance. Rumen metabolites like pH and total nitrogen and its fractions (ammonia N, TCA precipitable N and soluble N) remained similar amongst treatment except TVFA. Thus, soybean oils and/or rice bran oils at level of 3% of DMI can be effectively incorporated in ration of lactating Surti goats without affecting nutrient utilization and rumen fermentation.
