Abstract
Phosphorous represents an important element in poultry nutrition; cereal grains and nut meals being important sources in ration formulation but their phosphorus is mostly not available, due to lack of phytase enzyme. A total of 108 male broiler chicks (Ross 308) were used in a 42-day experiment with objectives to study the effect of supplementing phytase with or without added di-calcium phosphate (DCP) to broiler chickens on their performance. Birds were allocated to three treatments in a completely randomized design (CRD) with three replicates. Treatment one T1 (control), diets supplemented with + 0.1% di-calcium phosphate DCP, treatment two T2 (1500 FTU/Kg phytase + 0.1% DCP) and treatment three T3 (1500 FTU/Kg + 0.0 % DCP). Results showed significant (P≤0.05) differences in feed intake (FI), body weight (BW), body weight gain (BWG) and feed conversion ratio (FCR), where T3 recorded the best results. The gastrointestinal tract (GIT) and the associated organs showed significant (P≤0.05) differences in their weights and lengths. There were no significant (P≥0.05) differences in meat chemical properties, (DM%, Ash%, EE%, Ca% and P%) and sensory evaluation (taste, flavor, tenderness and overall) of the breast muscle. However, there were no significant (P≥0.05) differences in meat color and mortality rates. There were significant (P≤0.05) differences in tibia bone physical properties (weight, length, thickness of the medial wall, lateral wall and medullary canal diameter) and tibia bone chemical composition and manure where T3 had the best results. There were significant (P≤0.05) differences in the economics appraisal where T3 had the least cost and highest revenue. It reveals that using the (1500FTU/Kg) phytase without added DCP is the best in performance parameters and economic appraisal. It can be concluded that (1500FTU/Kg phytase without DCP) can be added to broiler diets for good performance, best returns and reduced environmental pollution
