Peanuts and sesame are two important sources of macronutrients and micronutrients. The objectives of this study were to evaluate the weight gain, protein quality and digestibility of eight legume-based diets in Wistar rats during a period of four weeks. The diets were classified as:
control diet, diet A (skim milk), diet B (nitrogen free), diets C, D, E, F (with peanuts in a proportion that varied from 100%, 75%, 50% to 25%, mixed with skim milk), diets G, H, I, J (with sesame in a proportion that varied from 100%, 75, 50% to 25%, mixed with skim milk). The study showed significant differences in weight gain when comparing with the control diet, particularly with diet D (75% peanut) with 226 g (SD=55.29) (p<0.05), diet H (75% sesame) with 218.16 g (SD=56.28) (p<0.05), and diet I (50% sesame) with 216.83 g (SD=45.86) (p<0.05). The study showed that the diets with skim milk and legumes were highly digestible (96% - 100%), with protein efficiency ratio (PER) of 2.73, very similar to the control diet. These formulations are promising and have potential implications for human nutrition.
