To determine metabolizable energy values for domestic fish meal, silk warm pupae, linseed oil meal, cotton seed oil meal, corn gluten meal, single cell protein by chromic oxide indicator method, 105 irds of a commercial broiler at 4 weeks age were employed in this experiment. The results obtained are summarized as follows: 1. The linear standard curve of chromic oxide at 430mμ has the equation form of Y=0.395X. 2. It was shown that corrected metabolizable energy per gram of domestic fish meal, linseed oil meal, cotton seed oil meal, silk warm pupae, corn gluten, single cell protein were, respectively, 2,776 ㎉, 1,081 ㎉, 1,471 ㎉, 5,550 ㎉, 3,106 ㎉, 2,246 ㎉. 3. In body weight gain and feed efficiency, corn gluten group was superior to the ethers and linseed oil meal group was significantly lower than the others.
