Abstract
Ninety-five growing female rats were divided into 21 groups and each group was fed on respective diet. The diet contained either one of two meatless meats textured out of soy protein or casein, the amount of which was in one of the following percentages : 3, 5, 10, 18, 23, 30 and 40%. The growth of rats fed on the meatless meat was slower than that on casein, especially at the lower protein levels of 5 and 10%. Several nutritive values of the two sorts of meatless meat and casein were as follows : Nitrogen Growth Index-15, 11 and 19; Net Protein Ratio-2.98, 2.65 and 4.23; Protein Retention Efficiency-47.6, 42.5 and 67.6; and Protein Efficiency Ratio-2.27, 2.06 and 2.66.
