Abstract
1. The crude compositions of samples of triticale and rye are given together with more detailed analyses for the protein and carbohydrate fractions.
2. By regression analysis of absorption on intake, the true digestibilities of the crude protein, using colostomised birds, were calculated to be 85.2 and 72.0%, those of the crude fat 94.4 and 89.7% and those of the carbohydrate 82.0 and 75.5% for triticale and rye respectively.
3. The classical metabolisable energy values of the triticale and rye samples were found to be 14.08 and 12.51 MJ/kg (3.36 and 2.99 Mcal/kg) respectively.
4. It is concluded that triticale is a better food source for the chicken than either wheat or rye.
