In comparison to the 44% crude protein of soybean meal (SBM), the protein content of rapeseed meal (RSM) is about 35-40% and has a physiologically suitable amino acid profile for animal nutrition. However, RSM contains nutritionally unfavourable substances such as glucosinolates, sinapin, tannin, phytate and non starch polysaccharides (Kocher et al., 2000). Enzymes have potential to improve the nutrients availability of diets containing antinutritional factorst. NSPs include cellulose, B-glucans, arabinoxylans, and pectins that may increase viscosity of digesta and cause a decrease in nutrient digestibility and performance of broiler chickens. Phytase from digestive secretions, some feed ingredients, resident bacteria and exogenous microorganisms is present in the digestive tract of broiler chickens (Kornegay, 2001), but its efficiency at a practical level is very low. It accepted that broilers lack sufficient levels of phytase activity to effectively hydrolyse the phytate molecule. Phytate-bound P is not well digested, so inorganic P is added to broiler diets that increases feed costs (Lescoat et al., 2005). The purpose of this study was to investigate the replacement value of SBM with locally grown RSM and two enzymes (NSP-degrading and phytase) on the weight of carcass, some organs, and amount of blood-Ca and P of broiler chickens.
