Background: Protein-energy malnutrition is regarded as one of the public health problems in developing countries as a result of poor feeding due to poverty. This study was conducted to compare protein quality of two samples of commercial weaning food, Cerelac (based on dry milk, wheat and banana containing probiotic Bifidobactriumlactis) and Ghoncheh (based on dry milk, wheat, and honey), in rats. Materials and Methods: This experimental study was conducted on 64 male rats aged 23 days in 8 groups under 8 diets, including 2 test diets (Cerelaccontaining probiotic Bifidobactriumlactis and Ghoncheh), 1 standard diet (casein), 1 basal diet (protein free) for true protein digestibility and apparent digestibility study, 2 test diets, 1 standard diet, and 1 basal diet for net protein ratio, protein efficiency ratio, and food efficiency ratio study. Results: The contents of true protein digestibility for casein, Cerelac, and Ghoncheh were 93.77, 84.23 and 89.82, respectively and the results were significant in all of the groups (p<0.001). The content of net protein ratio for casein, Cerelac, and Ghoncheh was 4.38, 4.1 and 3.17, respectively and the results were significantin all of the groups (p=0.009). The contents of protein efficiency ratio for casein, Cerelac, and Ghoncheh were 3.05, 2.59, and 2.01, respectively and the results were significant in all of the groups (p<0.001). Conclusion: The findings of this study indicated that the protein value of Cerelaccontaining Bifidobactriumlactis was higher than Ghoncheh.
