摘要

This study evaluated the effects of genotype, dietary ginger supplementation, and genotype × treatment interactions on growth performance, serum biochemical indices, liver and kidney function markers, and oxidative status of broiler chickens. A total of 200 day-old broiler chicks comprising 100 Abor Acres and 100 Cobb 500 were randomly allotted to four dietary treatments containing 0, 0.5, 1.0, and 1.5% ginger powder in a 2 × 4 factorial arrangement within a completely randomized design. Each treatment consisted of 24 birds with three replicates of eight birds, and the trial lasted 56 days. Genotype significantly affected performance, renal markers, and antioxidant status (p ≤ 0.05), with Cobb 500 generally exhibiting superior values, whereas Abor Acres showed significantly higher serum biochemical and liver enzyme values. Dietary ginger supplementation also significantly influenced performance, serum biochemical parameters, renal markers, and antioxidant status (p ≤ 0.05). Significant genotype × treatment interactions (p ≤ 0.05) were observed for feed intake at week 3, total protein, albumin, cholesterol, triglycerides, HDL, LDL, alanine aminotransferase (ALT), alkaline phosphatase (ALP), urea, creatinine, and glutathione peroxidase (GPx). Feed intake at week 3 showed parallel interaction patterns, with Cobb 500 maintaining higher values than Abor Acres. Total protein was optimized at 1.0–1.5% ginger inclusion in both strains, while albumin responses indicated optimum values at 1.0% in Cobb 500 and 1.5% in Abor Acres. Cholesterol reduction was greatest at 1.0% ginger inclusion in Cobb 500 and 1.5% in Abor Acres. Triglycerides declined markedly at 0.5% inclusion in Abor Acres and 1.0% in Cobb 500. HDL concentrations were lowest at 1.0% inclusion in Cobb 500 and 1.5% inclusion in Abor Acres (19.5 mg/dL), whereas LDL was minimized at 0.5% and 1.5% inclusion levels in Cobb 500 and Abor Acres, respectively. ALT values were lowest at 1.5% inclusion in both strains. Peak ALP, urea, creatinine, and GPx responses occurred at different inclusion levels between strains, indicating genotype-dependent metabolic, hepatic, renal, and antioxidant responses. These findings highlight the importance of genotype-specific dietary ginger supplementation strategies in broiler production.
