INFLUENCE OF DIET FAT ON POST-IRRADIATION GROWTH AND FOOD UTILIZATION IN THE RAT
Studies were made on the influence of diet fat on growth in control and irradiated rats. Animals were fed aritificial diets containing 19% protein from skim milk powder, and furnishing 0, 37, or 68% of diet calories as either added corn oil or butter fat. Rats from each diet group were treated with 3 biweekly doses of 300 r each, to administer a maximal injury with minimal acute mortality. Best growth occurred in control and irradiated rats on the high butter diet, with the moderate corn oil diet next best; poorest growth occurred on the fat- deficient diet. Best growth did not require high levels of calorie or protein intake, but it did accompany most efficiert utilization of diets. Since irradiated animals ate about as much as their unirradiated controls, the 20% lower weight gains of the former seem to result primarily from decreased efficiency of diet calorie and protein utilizations. These latter were least adversely affected by irradiation in rats on the high butter diet. (auth)
