This study was carried out to assess the locational variation in the nutritive value of some crop residues fed to small ruminants and to determine the best crop residues suitable for these animals. Samples of the crop residues (Cassava peels, plantain peels, cassava leaves and plantain leaves) were collected from National Root Crop Research Institute Umudike (South East) and International Institute of Tropical Agriculture (IITA) Onne (South South). They were sun – dried on a concrete floor for 3-5 days. The samples were taken to the laboratory and analyzed for proximate compositions (moisture content, ash, crude protein, crude fibre, ether extract, dry matter and carbohydrate), mineral compositions (phosphorus, sodium, calcium, magnesium, potassium and zinc), anti – nutritional factors (Saponin, tannin, phytate and oxalate) and fibre fractions (neutral detergent fibre, acid detergent fibre and acid detergent lignin). The result showed significant differences (P<0.05) in proximate composition, mineral content, anti-nutritional factor and fibre fractions of the crop residues. Crude protein (CP) was highest in cassava leaves from Umudike (25.31%), crude fibre (CF) was hjghest in plantain leaves fron Onne (30.49%), ash was highest in plantain peels from Umudike (17.45%), Ether extract was highest in plantain peel from Onne (6.20%) and dry matter (DM) was highest in cassava leaves from Onne. The samples showed moderate levels of minerals. Saponin and tannin were within the levels recommended for sheep and goat production in all the crop residues except in plantain peels from Umudike and Onne. Their saponin and tannin levels were 6.29%, 2.79% and 6.48%, 3.72% for plantain peel from Umudike and plantain peel from Onne, respectively.
