This experiment was undertaken to investigate the nutrient composition and level of inclusion of rapeseed meal (RSM) Brassica napus, Vs ''Tower' in the broiler finisher rations. The chemical analysis indicates that the CP and ME value of RSM were 37.81% and 2620 kcal/kg respectively, indicating the potential of the feed as protein supplement for both non-ruminants. A total of 396 mixed sex, four weeks old chicks were fed diets containing 0, 5, 10, 15, 20 and 25% RSM. Increasing the dietary level of RSM significantly increased feed intake (p0.01), body weight gain (p0.05) and dry matter efficiency ratio (p0.01). This was accompanied by a significant decreased in intake to gain ratio (p0.05) and feed cost per kg live weight gain (p0.01). The result of the experiment revealed that RSM could be included up to 25% in broiler finisher diets without adversely affecting performance.
