To evaluate the nutritive value of Canadian rapeseed mead on growing performance of broiler, 480 chicks of Starbro strain were subjected to the 8 treatments consisting of 4 levels of rapeseed meal substituted for soybean meal(0, 4, 8, 12%) and 4 levels substituted for fish meal (3, 6, 9, 12%). At the end of the feeding trial, a metabolism trial was conducted to observe the utilizability of nutrients and nitrogen retention. the results obtained are summarized as follows: 1. Chemical composition including the amino acids of the rapeseed meal analyzed was closely comparable to the data previously reported in literature. 2. Different levels of rapeseed meal did not make any significant differences among the treatments in either body weight gain or feed efficiency. A slight hypothyroidism induced by feeding rapeseed meal was discussed. 3. Birds fed high level of 12% rapeseed meal utilized the dietary fat more effectively, but less NFE was utilized and this might reflect the low availability of caribohydrates of rapeseed meal. There was little consistency in nitrogen retention. It might be concluded that rapeseed meal can be used as high as 12% in the broiler diet without any apparent adverse effect.
