Abstract

The protein efficiency ratios (for a 4 week period) of infant food formulation based on groundnut protein isolate, full-fat soya flour, dextrimaltose and hydrogenated groundnut oil were 2,72 and 2.33 at 15 and 20 per cent levels of protein intake respectively and did not differ significantly from the corresponding values (2.79 and 2.23 respectively) for milk food of similar composition. The relative efficacy of the infant food formulation as compared to milk food in meeting the protein requirements of protein depleted animals was studied. The protein in the diet was maintained at a level of 20 per cent. No significant differences were observed in the moisture, fat and protein contents of the livers and carcasses of depleted rats, repleted on infant food or milk food. The animals, when fed on a nitrogen-free synthetic diet for a period of 26 days, lost on an average, 30 per cent of body weight and 40 per cent of liver weight. The red blood cell count, haemoglobin level and total serum proteins in the blood of rats were restored to normal levels, when the protein depleted rats were repleted on infant food or milk food for a period of 21 days. The mean gains in body weight per g of protein retained or the protein retentions per 100 g gain in body weight of rats repleted on infant food with or without added dl-methionine did not differ significantly from the corresponding values obtained for milk food. The mean gains in weight per g of protein intake as also the mean protein retentions per 100 g protein intake of rats repleted on infant food were significantly lower than that of rats repleted on milk food.
