The influence of supplements of cotton seed cake (CSC) on the voluntary intake and utilization of sorghum glume (SG) by the goat. was studied in a 4 x 4 Latin Square digestibility trial. The study involved a total of 12 West African dwarf goats made up of 8 dry, non-pregnant does and 4 bucks aged between 14 and 20 months with av. live weight of 13.7kg. There were four diets in all, made up of 3 experimental diets in which cotton seed cake replaced, in each case, 25, 50 and 75% of the sorghum glume. The control diet was the unsupplemented sorghum glume. The goats were fed dry matter at 4% of body weight and water and mineral salt lick were provided ad libitum. The dry matter intake (DMI) increased (P < 0.05) with CSC supplementation but the DMI value between 50 and 75% CSC levels were comparable ( P > 0.05). Weight gains in all treatments were positive being highest (6334 ± 12.7 g/d) with the 50% CSC supplementation of the sorghum glume and lowest (11.67±10.85 g/d) with the (control) unsupplemented sorghum glume. Increases in the oil seed cake supplementation of the sorghum glume resulted in increases (P < 0.05) in nitrogen intake across the treatments. Increases in the feed digestibility, nitrogen retention, digested feed energy and organic matter were significant (P < 0.05) up to 50% cotton seed supplementation of the sorghum glume. The performances of the goats on the 50% CSC and 75% CSC supplementation of sorghum glume are comparable (P < 0.05) in respect of feed intake, nitrogen retention and nutrients digestibilities. A juidicious use of the protein concentrate for optimum feed intake and feed utilization makes the 50% CSC supplementation more desireable. A 50% cotton seed cake supplementation of the sorghum glume is recommended as suitable in the dry season feeding of the goat.

Key words: Goat, sorghum glume, crop residue, nitrogen supplementation.
