The effect of different molasses levels (30, 35, 40, and 45%) in the diet of sheepwas invesigated. Four rations were formulated so as to be iso-caloric and iso-nitrogenous, and in which the different molasses levels replaced groundnut cake. 32 yearling sheep were subjected to two trials, feeding and digestibility, where in the former a completely randomized design was used with eight animals in each treatment and in the latter a 4X4 Latin Square design was used. The results revealed that dry matter intake decreased steadily with the increase of molasses level, but no significant differences could be detected. Body weight gain increased (P0.05) with the 30 and 40% molasses levels although the amounts of nitrogen retained decreased (P0,05) with the 40% level suggesting that the gain in weight could be due to fat deposition. Higher (P0.05) amounts of nitrogen retention were observed with the 30 and 35% levels. Ether extract digestibility at the 35% levelproved to be significant (P0.05). Rumen pattern of fermentation or blood urea nitrogen did not differ much with the differentdiets. However, the sampling time shwed that, rumen pH and rumen ammonia nitrogen decreased while rumen volatile fatty acids increased 6 hours post-feecing but without significant differences
