Abstract

The feeding values of 3 grains and 2 brans were determined using mature R.I.R. cocks. The feeding values of yellow corn were: 80.42 S.V., 78.22 T.D.N., and 3285.2 kcal M.E. The corresponding values for barley were: 49.29, 51.08, and 2145.4. The feeding values of wheat were lower than those of corn by about 10%.
The associative effect of the basal ration on the digestion coefficients of the tested ration is evident from the data of wheat by direct and indirect methods. The feeding values of wheat bran were found as: 27.02 S.V., 30.I6T.D.N., and 1266.7 kcal M.E. The corresponding values for rice bran were: 48.43, 43.82, and 1840.4. The low feeding values of barley, wheat bran and rice bran limit their use in high energy rations for broilers and layers.
The linear multiple regression equation of the effect of CF and NFE on TDN was calculated. The value of this equation in predicting the TDN from chemical analysis is obvious.
