Abstract
Twelve male desert bucks, initial body weight 9-12 kg were used in this study. Monensin was added 10 or 30 mg/kg dry matter to (15.75%) or (22.75%) crude protein of the diets. The animals were divided into four groups, they were fed the diets (2 x 2 factorial arrangement). Average daily gain was improved by 18% in animals fed the higher level of monensin compared with animals fed the low level of monensin. Monensin also reduced feed intake by 15.4% in diet A and 1.12% in animals fed diet B. There was an improvement in the nitrogen retention in the body with high levels of monensin in each diet. Feed conversion ratio was also improved by the higher level of monensin. The acetate: propionate ratio was reduced significantly (P<0.05) with higher level of monensin. The level of butyrate did not change much with monensin. There was a slight increase in rumen PH at the high level of monensin. High level of moncnsin reduced rumen NH3-N in this study.
