Effects of dietary phytosterols supplementation on serum parameters, nutrient digestibility and digestive enzyme of white feather broilers

Abstract

The aim of this study was to evaluate the impacts of dietary phytosterol (PS) addition at different levels on serum parameters, nutrient digestibility and digestive enzyme activities of white feather broilers. A total of 600, 1-day-old male broilers were randomly divided into five groups with six replicates and were fed a basal diet supplemented with 0 (control group), 10, 20, 40, or 80 mg PS/kg for 42 days. The results showed that dietary supplementation with PS at 20 and 40 mg/kg decreased malondialdehyde accumulation and increased glutathione peroxidase concentrations compared with the control group (p
