Abstract: The amino acid digestibility in broiler birds fed with rumen epithelial scrap based finisher meal was investigated and compared with those of standard Fish Meal (FM) and other meals in poultry use. This was in a quest to search for an alternative and local source of protein in broiler-chick meal due to adulteration and high cost of fish meal. Three groups of eighteen 4-week-old broiler chickens in each group were fed with three isocaloric finisher diets: basal diet, Rumen Epithelial Scrap based Meal (RESM) and Fish Meal (FM) containing 0% Crude Protein (CP), 19.5 and 19.5% CP, respectively. The broiler birds, in their starter phase, were fed a nutritionally sound starter mash (23% CP and 2.8 Kcal g-1 ME). At day 14 of the experiment the birds were sacrificed and feed remnants in their crops and faecal deposits in their rectum were extracted for amino acid analyses. The consumption of the RESM and FM by the broiler birds were not significantly (p<0.05) different. The amino acid digestibility co-efficient obtained for lysine, methionine, cystine and other amino acids in broiler birds fed with RESM compared favourably with values obtained by earlier researchers for meat meal, blood and feather meal but the lysine digestibility coefficient was significantly (p<0.05) lower than the value obtained in the broiler birds fed FM. We inferred that rumen epithelial scraps, an abattoir by-product which constitutes an environmental waste, could be utilized as a source of protein in broiler feed production with appropriate supplementation with lysine.
