Abstract

A total number of 600 one-day-old male Ross 308 broiler chickens were used in a 3×2 factorial experimental design conducted until 35 days old. Birds were equally assigned to six groups, with 5 replicates per treatment of 20 chicks per replicate. This study evaluated the effects of inclusion three levels (0, 4 and 8%) of olive cake meal (OCM) and two levels of phytase supplementation (0 and 150 g/ton) on productive performance, some blood parameters, nutrients retention efficiency (calcium and phosphorus), and economical efficiency. Results indicated that inclusion of 8% OCM with or without phytase significantly (P ≤ 0.05) improved body weight, body weight gain, feed consumption and feed conversion ratio compared to the control group. Additionally, broiler chicks fed diets containing 8% OCM with or without phytase supplementation exhibited the better retention efficiency of calcium and phosphorus, and economical efficiency than the control group. Based on the obtained results, it is recommended to use phytase to improve the nutritional value of OCM. In conclusion, the inclusion of phytase to OCM diets resulted in enhanced growth and nutrient utilization in broilers.
