Abstract
Male adult rats (30) were investigated to compare the nutritive value of brown beans [Vigna unguiculata] (BP); dehulled brown beans (DBP); white beans (WP); dehulled white beans (DWP); bambara groundnut [Voandzeia subterranea] (BG); dehulled bambara groundnut (DBG), supplemented with rice flour (R) in various blends to provide 2 g N/100 g of the diet daily for a 12-day N balance study. The rats were allotted to 6 groups of 5 rats such that differences in body weight of each group did not exceed 5 g. Dehulling markedly improved protein nutriture of brown bean diets as judged by N intake, digestibility and retention. The BV [biological value] for rats fed diets containing brown beans was higher than for those fed other test diets. Brown beans, regardless of treatment, probably contained better quality protein than other legumes.
