| dc.description.abstract | In a 90-day growth trial, 18 Murrah buffalo bull calves were randomly allotted to three dietary treatments (T1 to T3) comprising of Super Napier green fodder, concentrate mixture and rice straw viz. local variety (T1; Control), DRR Dhan – 45 (T2) and DRR Dhan – 48 (T3). All the three varieties of rice straws were ground using chopper cum grinder, mixed with concentrate mixture and offered to bull calves in respective groups in TMR form to meet the nutrient requirements (ICAR, 2013). All the three diets were evaluated for their effect on growth, nutrient utilization, serum biochemical and mineral profile in buffalo bulls. The per cent DM, OM, CP, EE, CF, NFE, TA, NDF, ADF, hemicellulose, cellulose, ADL and silica were 93.11, 85.63, 3.19, 2.66, 37.09, 35.8, 14.37, 76.19, 52.15, 24.04, 26.83, 14.40 and 10.96; 93.98, 86.39, 5.78, 2.41, 34.94, 37.24, 13.61, 71.17, 46.14, 25.03, 24.80, 12.18 and 9.26; 93.90, 87.69, 5.62, 2.86, 35.80, 37.31, 12.31, 71.40, 45.34, 26.06, 24.26, 13.07 and 8.06 percent in control, Dhan - 45 and Dhan – 48 varieties, respectively. The calcium and phosphorous content in control, Dhan - 45 and Dhan – 48 varieties were 0.51 and 0.10; 0.56 and 0.12; and 0.58 and 0.13 percent, respectively. In vitro parameters studied viz. IVGP (ml/200 mg DM), IVDMD (%), IVOMD (%), ME (MJ/kg DM), PF (mg/ml), MBP (mg), FE (mg DM) and SCFA (mM) revealed no significant differences (P>0.05) between biofortified varieties of rice straw as compared to the control. The study indicated that feeding zinc biofortified varieties of rice straw increased significantly (P0.05) on feed efficiency and cost of feed / kg gain in buffalo bull calves as compared to the control. The cost of feed / kg gain decreased (P>0.05) by 11.04 and 6.52 in T2 and T3, respectively as compared to T1. Feeding zinc biofortified rice straw varieties in the diet had no effect (P>0.05) on DM, OM, CF, NFE, NDF, hemi-cellulose and cellulose digestibility as compared to control. However, digestibility of CP and EE were significantly higher (P0.05) on TDN (kg/d), DE and ME intakes (M Cal/d) as compared to the control. The study revealed that feeding of zinc biofortified varieties of rice straw had no effect (P>0.05) on serum biochemical profile in buffalo bull calves as compared to the control. Further, feeding zinc biofortified varieties of rice straw had no effect (P>0.05) on serum calcium and phosphorous content while it increased significantly (P<0.01) the serum zinc content as compared to those fed control straw diet. Thus, it is concluded that zinc biofortified varieties of rice straw viz. Dhan-45 and Dhan-48 can be fed to buffalo bull calves for increased body weight gains and decreased cost of feeding without any adverse effects ensuring profits to the farmers / dairy entrepreneurs. | en_US |
