Abstract
A growth trial was conducted on 45 intact male Sudan desert lambs to study the effect of groundnut hulls and halum level on lamb feedlot performance and carcass characteristics. Three iso-caloric and iso-nitrogenous diets were formulated. Diet I contained hulls and 10% groundnut halum, diet II contained 15% groundnut hulls and halum diet III contained 20% groundnut hulls and 20% groundnut halum in addition groundnut cake, wheat bran, molasses plus salt and Caco3 were added to each diet. The ingredients were mixed together and fed ad libitum for 63 days. Subsequently the lambs were slaughtered and their carcasses were studied. The level of groundnut hulls and halum had no significant (P>0.05) effect on performance of experimental lambs hence, the final weight, average daily gain, daily feed intake and feed conversion ratio showed no significant (P>0.05) difference among the dietary treatments. Dietary treatments did not significantly (P>0.05) affect carcass parameters. The wholesale cuts were not (P>0.05) affected by dietary treatments. Different levels of groundnut hulls and halum failed to show any effect (P>0.05) on percentage of muscle, bone in addition to muscle: bone ratio, however diet III had significantly (P<0.0l) lighter carcass fat percentage. The Non carcass components other than kidney fat showed significant (P<0.05) differences among the dietary treatments. Hence equal proportions of groundnut hulls and halum can be used in lamb feeding to constitute 40% of the diet and achieve a daily gain of 150g. Such cheap diets can also be recommended for lamb feeding during dry season
