Abstract

The performance of West African Dwarf (WAD) goats grazing natural pasture and supplemented with different levels of urea-treated cassava peels (UTCP) was evaluated. The urea treatments were 0% UTCP, 4% UTCP (40g urea/kg), 6% UTCP (60g urea/kg) and 8% UTCP (80g urea/kg).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. Total daily feed intake, daily weight gain and weight gain per gramme nitrogen intake varied significantly (P<0.05) among treatments,. Similarly, significant (P<0.05) effect of urea treatment was observed on thoracic girth change, daily water consumed and feed conversation ratio (FCR). Animals on 4% UTCP recorded superior performance in daily weight gain, weight gain per gramme nitrogen intake, FCR and thoracic girth change. This indicated that ammoniation at 4% improved weight gain significantly (P<0.05) compared to other treatment levels. No significant (P>0.05) increase in blood urea accompanied ammoniation and blood urea concentration did not exceed the toxic level of 10mg per litre.
