Data are reported from observations on four generations of rats maintained on irradiated and untreated diets. As measured by the number and percent of young weaned, the irradiated diet was equal to the untreated diet for reproduction and lactation in the first and second generation. The irradiated diet was inferior to the untreated diet in the third generation. The diets had equal effects on life span; however, most of the rats on untreated diet grew slightly faster than those receiving the irradiated diet. Chicks receiving an irradiated diet supplemented with vitamins A, D, and E consistently grew at a slightly slower rate than those receiving the untreated diet. When tbe complete diet was irradiated with no vitamin supplement added, the chicks grew slowly and mortality was high. Fat, protein, and a mixture of 10 B-vitamins were irradiated separately in an attempt to locate the component of the diet affected by irradiation. Results show that the fat and the mixture of 10 B-vitamins, when low in moisture, were not affected by irradiation of the diet. The nutritive value of casein did not appear to be decreased by irradiation. Irradiated gelatin appeared to be inferior to untreated gelatin. Data are included from studies to determine the effects of irradiation on individual vitamins and enzymes. (C.H.)
