  • Sterilization of Diets by Gamma irradiation

抄録

The increasing use of germ-free and specific pathogen-free (SPF) animals in experimental works has led to a growing demand for more advantageous sterilization procedures for animal diets. Before and after gamma-irradiation at doses ranging from 0.5 to 3 Mrad, practical-type diets for chicks were assayed for their vitamin content. Irradiation had little effect on vitamin A, vitamin D, thiamine, riboflavin and ascorbic acid, while 30 to 40 percent of vitamin E was lost. The results of feeding study with chicks indicated that the irradiation of diet did not produce any significant disorders in growth, feed conversion and metabolizable energy for three weeks.
