Performance of sokoto red goat buck fed urea treated and untreated rice milling waste in North Western Nigeria

The study was carried out at the Livestock Teaching and Research Farm of Federal University Dutsin-Ma to monitor performance Sokoto red bucks fed urea treated untreated rice milling waste. Twenty entire male were used. experimental animals allotted (n=5) in a completely randomized design (CRD) diets A B with 15% 30% inclusion levels waste, respectively, while C D contained (CRD). feeding trial lasted for 84 days digestibility 14 days. Three randomly selected from each treatment housed metabolic cages their faeces collected seven using faecal bag after adaptation period. weighed bulked 10% oven-dried before they stored polythene bags until required analysis. Urine also inside urinary funnel piped into bottle containing 2 ml sulphuric acid trap nitrogen content. urine sampled freezer -2C chemical dry matter intake significantly higher (P<0.05) treatments than other treatments. However, this did not result better (feed efficiency Cost feed/ live weight gain) as shown that had gain, feed efficiency, nutrients retention. cost per kg be lower compared which A. concluded diet level waste best among all because lowest 1.40 USD/kg 0.10.
