Effect of Graded Levels of Dried Orange (Citrus sinensis) Byproducts on Production Efficiency, Blood Parameters and Antioxidant Status of Broiler Chickens

Background: Orange wastes are bioactive compounds produced during the industrial transformation.The experiment was conducted to evaluate effects of feeding dried sweet orange byproducts (DOP) on broiler growth performance, serum metabolites and antioxidant status. Methods: A total 200 20-day experimental chicks were distributed into a completely randomized design which included 4 dietary treatments with 5 replicates 10 birds fed each. The control diet no corn substitution three diets containing 5, 15 % Dried Pulp. Feed intake (FI), body weight gain (BWG), feed conversion ratio (FCR), carcass traits, components, blood status measured. Result: FCR BWG chickens improved when using graded levels DOP compared group (P less than 0.05). Serum protein glucose significantly increased 0.0001) in groups control. Cholesterol triglyceride decreased groups. Higher Aspartate amino transferase, Lactate Dehydrogenase Creatine Phospho Kinase activities observed Control other treatments.
