The effect of different supplementary protein sources on average body weight gain, feed intake, digestibility, nitrogen balance and feed conversion was studied using twenty-four yearling Mubende goats. The animals, which averaged 15.4±2.1 kg, were assigned to four treatment diets in a randomized complete block design. The basal diet consisted of guinea grass hay fed together with 200g of maize bran/mineral mixture. The four protein supplements included lablab hay (LBLB), sweet potato vines (SPV), cassava leaf meal (CLM) and sunflower meal (SFM). The protein supplements supplied 10g N daily for a feeding period of 100 days. Thereafter, all male goats were transferred to metabolic cages for a nitrogen balance trial. Cassava leaf meal supported better growth and feed conversion and higher N retention compared with Lablab hay, sweet potato vines and sunflower seed meal.
