An evaluation of the protein and energy value of wheat, barley and maize when fed in conjunction with wheat offals was made. The Gross Protein Value test, and two methods of estimating protein and energy retention, one the conventional balance technique and the other body analysis, were used. For protein and energy provision, the cereals were of equal value when fed in this way. The values obtained by the two methods of determining protein retention varied significantly and this is discussed. The relative accuracy of the several methods is also discussed together with the validity of the Gross Protein Value test.
