Effects of phytosterol supplementation on growth performance, serum lipid, proinflammatory cytokines, intestinal morphology, and meat quality of white feather broilers
ABSTRACT: The aim of this study was to evaluate the effects of dietary phytosterol (PS) addition at different levels on growth performance, serum lipid, proinflammatory cytokines, intestinal morphology, and meat quality in broilers. A total of 600, 1-day-old male broilers were allocated into five gr...

| description | ABSTRACT: The aim of this study was to evaluate the effects of dietary phytosterol (PS) addition at different levels on growth performance, serum lipid, proinflammatory cytokines, intestinal morphology, and meat quality in broilers. A total of 600, 1-day-old male broilers were allocated into five groups with six replicates and were fed a basal diet supplemented with 0 (control group), 10, 20, 40, or 80 mg/kg PS for 42 days. Compared with the control group, the administration of PS at doses of 40 and 80 mg/kg significantly increased the average daily feed intake and average daily gain of broilers during the experimental period. Similarly, PS at a dosage of 20 and 40 mg/kg increased the concentrations of interleukin-1β, interferon-γ, interleukin-2, and interleukin-6 but decreased triglyceride, total cholesterol, and low-density lipoprotein cholesterol content of serum (P < 0.05). Dietary PS at less than or equal to 40 mg/kg level increased (P < 0.05) villus height, and villus height to crypt depth ratio in the duodenum and ileum. Supplementing PS increased the pH value at 45 min post-mortem and decreased drip loss and shear force of breast muscle (P < 0.05). Dietary PS administration at 20 and 40 mg/kg decreased malondialdehyde accumulation but increased total antioxidant capacity and superoxide dismutase activity of breast muscle compared with the control group (P < 0.05). PS increased the concentrations of total amino acids and flavor amino acids as well as eicosapentaenoic acid, docosahexaenoic acid, and total polyunsaturated fatty acids but decreased saturated fatty acids in breast muscle (P < 0.05). It was concluded that dietary PS supplementation, especially at 40 mg/kg, could improve growth performance, serum lipid, proinflammatory cytokines, intestinal morphology, and meat quality in broilers, providing insights into its application as a potential feed additive in broiler production. |
