Rapeseed is one of the most important oil seed in the world, and it is a valuable source of high quality protein as well as edible oil. Its protein comprise 35～45% of the meal that remains after extraction of the oil. The balance and availability of its amino acids are comparable with those of soya bean meal and if it is fortified with methionine and arginine, it can satisfy the entire requirement of the chicken. However, as containing some of the toxic substances or anti-nutritional factors such as fibre, phenolics, phytic acid and glucosinolates, it has deleterious effects on per-formance and health of the poultry and livestock. To minimise these effects the amount of the
