Effect of additional energy supplement of roasted soybean, soybean oil, bypass fat and extra concentrate on biochemical and metabolic profile in lactating Murrah buffaloes

Abstract

The study was conducted to see the effects of additional energy supplementation on the biochemical and metabolic profile in lactating Murrah buffaloes. The study was conducted at Livestock Farm, Adhartal, College of Veterinary Science and Animal Husbandary, N.D.V.S.U., Jabalpur (M.P.) for a period of one year (July, 2018 to June, 2019). A total of 30 lactating Murrah buffaloes were selected and randomly distributed to six groups. The study was carried up to 90 days post-partum. Animals of the group-1 (T1) received only basal diet as per ICAR (2013) requirements. Whereas group-2 (T2), 3 (T3), 4 (T4) and 5 (T5) were supplemented with 5% additional concentrate (T2) or 100 ml soybean oil (T3) or 100 g bypass fat (T4) or 100 g roasted soybean (T5) per animal/day. Other than feed, all the animals were maintained under same managemental conditions. The experimental animals were fed as per their body weight and production following ICAR (2013) requirements. They were fed twice daily according to schedule at 5:30 am and 3:00 pm and water was kept available to animals round the clock. The data recorded during the study were analysed statistically using descriptive statistics, one way ANOVA. Non-significant differences were observed among groups for blood glucose and BUN level. The higher NEFA concentration (mmol/l) was observed in groupT1 (0.47). The blood sodium concentration (mEq /L) had significantly decreased among the groups from initial day to 90th day of lactation and was higher in T3 (143.54) as compared to T1 (140.94) group. Significant findings were observed among groups about blood potassium, chloride and calcium concentration while phosphorus concentration was non-significant. Conversely, the blood alkaline phosphatase concentration had decreased significantly due to additional energy supplementation in different groups. Hence, based on the findings of study, it has been concluded that supplementation of 100g soybean oil was most economical followed by 100g of roasted soybean. It was followed by 5% additional concentration feeding and 100g bypass fat.
