The experiment was carried out in 12 local adult male goats of average body weights (26.49±0.87, kg) and they were allocated in 3 groups (4 goats in each). Multi nutrient blocks (MNB) were supplemented in first two groups i.e. in T 1 (no infection) and T 2 (Haemonchus contortus infection @ 1500 larvae) group, while, condensed tannins (CT) containing multi nutrient blocks (MNB-CT) were supplemented in T 3 (H. contortus infection @ 1500 larvae) group in completely randomized block design during a feeding trial of 75 days. All the animals were fed concentrate mixture @ 100g/ day, adlib wheat straw and MNB or MNB-CT to meet their maintenance requirement. Daily intakes (kg W 0.75 ) of dry matter (DM), organic matter (OM), concentrate mixture, MNB, MNB-CT, wheat straw and digestibility of DM, OM, crude protein (CP) and acid detergent fibre (ADF) differed significantly (P<0.05) irrespective of groups. MNB-CT supplementation significantly (P<0.001) reduced serum urea (mg/dl) level and faecal egg counts (FECs) in T 3 group as compared to MNB supplemented (T 2 ) group. Serum proteins differed significantly (P<0.001) among groups. It may be concluded that MNB-CT supplementation indicates a positive impact on protein bioavailability and encouraging impact on nutrient utilization, biochemical constituents and health status of goats by lowering serum urea and FECs.
