Twenty WAD bucks aged between 6 and 9 months and weighing on the average 7.7±1.2kg were randomly allocated to five treatment diets consisting of either natural herbage alone (NH); NH + 0% UTCP (0% UTCP,) NH + 4% UTCP (4% UTCP), NH + 6% UTCP (6% UTCP) and NH + 8% UTCP (8% UTCP) respectively in a completely randomized design experiment lasting 84 days to evaluate the potentials of UTCP as a supplement to natural pasture.
