Forty advanced pregnant Jafarabadi buffaloes of 2-4 parity were divided into two equal groups, viz. control and treatment (n = 20 each). The animals of control group were maintained on routine farm feeding schedule and those under treatment group were subjected to additional oral supplements daily with 50 g of chelated mineral mixture and 150 g of bypass fat along with concentrates for 6 weeks prepartum till 2 weeks postpartum, and then bypass fat was given @ 15 g/litre of milk produced till 60 days postpartum. All the buffaloes were subjected to blood collection on day -45, -30, -7, 0, 7, 15, 30, 45 and 60 peripartum. Postpartum animals were followed at weekly interval by per rectal palpation and ultrasonographically for uterine involution, first postpartum estrus and conception. The overall mean blood glucose of prepartum period increased significantly p less then0.01 on the day of calving and reduced back to prepartum levels within next 7 days postpartum in both the groups. The buffaloes supplemented with peripartum nutrients had significantly p less then 0.01 higher blood glucose levels than the control group. The mean plasma total protein 7.96 ± 0.04 g/dl and thyroid hormones T3 1.44 ± 0.05 ng/ml and T4 28.25 ± 0.86 ng/ml were found to be within the normal range, and did not vary between sampling days or between groups. The peripartum supplementation of bypass fat did not influence the levels of plasma total cholesterol. However, the levels of β-hydroxybutyrate BHBA and non-esterified fatty acids NEFA tended to be higher in control than treatment group at most of the peripartum intervals. The period of uterine involution 32.75 ± 0.57 vs 37.00 ± 0.56 days and service period 107.10 ± 4.43 vs 133.65 ± 6.04 days were significantly p less then 0.05 shorter with higher postpartum fertility 85 vs 50% CR in nutrient supplemented than control group. It was concluded that peripartum bypass fat and mineral supplementation prevented negative energy balance and/or ketosis and improved postpartum fertility in high yielding Jaffrabadi buffaloes.
