Description
Summary:The effects of levels of concentrate supplementation on feed intake, nutrient utilization and growth of southern Thai native male cattle were studied. Six cattle, 13±2 months old with average body weight (BW)of 142.9±6.7 kg were randomly devided into 2 groups with 3 heads for each group. The experiment was devided into 2 phases. In phase-I, the cattle were fed with plicatulum (Paspalum plicatulum) hay ad libitum,and were supplemented with concentrate (13.71% crude protein, CP) at 0.5% of BW (G1 group) and 1.0% of BW (G2 group), for 91 days. Dry matter (DM) intake, organic matter (OM) intake and CP intake of G2 group (3.74, 3.42 kg/h/d and 276.57 g/h/d, respectively) were significantly higher than those of G1 group(2.91, 2.65 kg/h/d; p
