Refined soya oil was irradiated with 2.5, 10, and 50 Mrad BETA -ray doses emitted by a Van de Graaff electron accelerator functioning at 1 Mev. The temperature of th oil was kept below 25 deg C during irradiation. As a result of irradiation, the iodine number of oil decreased while the viscosity progressively increased. It was expected that similar structural changes would occur in the oil from irradiation as a result of autoxidation. Female SpragueDawley rats were fed a diet containing 20% irradiated soya oil, unirradiated oil being used for the control group, 53% Mondamin, 2% cellulose, 20% vitamin-free- casein, and 5% salt mixture (Shaw diet). The animals fed 10- and 50Mrad irradiated soya oil showed a slight decrease in food intake and food utilization efficiency in comparison with the control group. The amount of vitamins given to each animal daily was 50 I.U. vitamin A, 45 I.U. vitamin D, 0.45 I.U. vitamin E, 40 mu g thiamine, 40 mu g riboflavin, 4 mu g pantothenic acid, and 20 mu g pyridoxine, 400 mu g nicoti mide, and 550 mu g choline chloride. The feedings were carried out for three weeks. The total cholesterol content animal serum consuming 10- Mrad irradiated soya oil was reduced from a control level of 43.1 to 35.6 mg%, the total lipid content rose from 240 to 300 mg%, and the lipid phosphorus content from 3.85 to 4.14 mg%. Animals re ceiving 50-Mrad irradiated soya oil did not show any ch in the lipid components of serum, although they exhibit creased resorption of the irradiated oil, as shown by the 2-fold increase in fecal lipid.
