Molasses based multinutrients herbal supplements (MMS) containing ground fenugreek seed and de-oiled mahua seed cake at two different ratios (1:1; MMS I or 1:3; MMS II) was evaluated under in vitro as well as in vivo conditions. For in vitro evaluation, concentrate mixture and wheat straw in 50: 50 ratio (on DM basis) was taken as substrate for the experiment. MMS I and MMS II were added at 2, 3 and 4% of the substrate, respectively. The total gas production (ml/g DM), partitioning factor (PF) and microbial biomass production (MBP) were found comparable in all the groups but significantly improved the IVDMD and IVOMD in supplemented groups. Under in vivo feeding trial, serum enzymes and minerals profile in buffalo calves were assessed during 9 months of experimental period. Fifteen male Murrah buffalo calves (10 to 15 months of age and mean body wt. 234.0±12.5 kg) were randomly distributed into 3 groups (5 in each group) according to randomized block design. All animals were fed with conventional concentrate mixture, available chopped green fodder (3-4 kg DM/d) and wheat straw ad lib to meet out nutrients requirement. While control group (C) were not fed supplements but groups T1 and T2 supplemented with MMS I and MMS II, respectively at 44 g/100 kg body weight or 200 g/100 kg metabolic body weight (kgW0.75). Serum AST, ALT activities and serum concentration of Ca, P, Fe, Mn, Cu and Co were comparable among 3 groups but serum concentration of Zn was significantly higher among supplemented groups. Thus, results show that supplementation of MMS improved IVDMD, IVOMD and serum Zn level resulting in to better health conditions of buffalo calves.
