ObjectiveThe study was developed to evaluate the protein quality of four multimixtures distributed in communities in Alfenas, MG, Brazil, to combat malnutrition. MethodsMale Wistar rats were randomaly assigned to one of six groups (n=6) and individually housed in stainless steel cages on controlled temperature (25ºC, standard deviation 2ºC) for 14 days. The standard group was fed a casein diet, control group was fed a free nitrogen diet and four-test groups were fed different multimixture diets. A biological assay was carried out to determine the protein quality by Protein Efficiency Ratio, Net Protein Ratio, Net Protein Utilization and True Protein Digestibility. ResultsThe Multimixture test groups showed lower (p<0.05) Protein Efficiency Ratio, Net Protein Ratio and digestibility than casein group. The net retention protein from multimixture test groups was lower (p<0.05) than casein group, except the group fed with multimixture contained a higher powdered milk proportion and was not added with powdered seeds, leaf cassava and egg shell powders in their formula. The multimixture digestibility was roughty 89% however the protein retention was approximately 27%. ConclusionIn conclusion, the multimixture showed low protein retention, did not promote adequate animal growth and was not capable of maintaining body weight in one multimixture test-group.
