Effect of consumption of molasses/urea blocks on the growth of housed bullocks fed ad libitum with Pennisetum purpureum.
Ten bullocks in individual pens were provided ad libitum with cut chopped pasture grass (Pennisetum purpureum). One group of five animals had access to a molasses/urea block (experimental group) and the other group of five did not (control group). Daily dry matter intakes of 5.04 kg/animal (control group) and 4.83 kg/animal (experimental group) were not significantly different. However the experimental group gained weight at a significantly (P less than 0.05) faster rate (514 g/animal per day) than the control group (346 g/animal per day). Food conversion efficiency was significantly (P less than 0.01) better in the experimental group (11.6 kg feed per kg weight gained) than in the control group (16.4 kg feed per kg weight gained). Mean daily intake of the molasses urea blocks was 206 g per animal.
