小麦胚芽の養魚飼料効果に関する研究-III

Abstract

In the previous papers1, 2), it was shown that the nutritive value of wheat germ was excellent and heat treatment of wheat germ improved its nutritive values for carp, Cyprinus carpio and roasting of the wheat germ by the dry method was more effective than autoclaving by the wet method. The present paper deals with the nutritive values of formulated diet of wheat germ and other materials, such as wheat germ and soybean, wheat germ and white fish meal, wheat germ and rice bran and so on. The results obtained are as follows: 1) The nutritive values of formulated diets consisting of defatted wheat germ and defatted soybean showed depressed values in proportion to the decrease of the wheat wheat germ content. 2) The nutritive values of defatted wheat germ with defatted white fish meal showed improvements when used as a formulated diet as compared with the case of single usage. 3) The formulated diets tentatively prepared with wheat germ, white fish meal, defatted rice bran, magna yeast, etc, showed higher value in feed efficiency than the commercial diet for carp.
