| Abstract | ||
| A feeding experiment was conducted to evaluate the effect of olive cake meal (OCM) in diets with or without commercial phytase (Ronozyme@ HiPhos (GT) for male ross broiler chickens at age 1-35 day. Two phytase supplementations (no phytase and phytase supplied at 150 g/ton) and three olive cake meal levels (0, 4, and 8% in the starter-grower feeds) are included. A total number of 720 male broiler chickens (Ross 308) at one day-old, were individually weighed and divided into six treatment groups; each group divided to 6 replicates, (n=20). Body weight and body weight gain were improved significantly (P<0.05) while; Feed conversion ratio and European broiler index were improved by feeding olive cake meal (OCM) at level of 8% with or without phytase compared with than control group on the other hand; abdominal fat was decreased. Interestingly, blood calcium, phosphorus, Newcastle disease titter (ND) were significantly improved, while total cholesterol, triglycerides were reduced by the mixture of OCM and phytase (P≤0.05) compared with control. Muscle malondialdehyde (MDA) concentration was decreased by feeding OCM at 4% or 8% with or without phytase (P≤0.05) while the GPX was improved. In summary, adding phytase to OCM diets improved fat consumption, which in turn improved male ross broilers development, nutrient utilization, and antioxidative response. Using phytase to increase the nutritional value of OCM is advised based on the results obtained. | ||
