摘要

The present study was conducted to assess the effects of lycopene (LP) supplementation on antioxidant status, lipid peroxidation, heat-shock proteins, and lipid profile in heat-stressed goat kids. Twenty-one healthy growing Barbari goat kids (4–8 months old) with an average body weight of 9.87 ± 1.09 kg were randomly allocated into three experimental groups, comprising seven animals per group. The activities of superoxide dismutase, catalase, glutathione peroxidase, and total antioxidant capacity increased linearly (P < 0.023) with increasing dietary LP levels. Conversely, concentrations of myeloperoxidase, reactive oxygen species modulator-1, and thiobarbituric acid reactive substances declined linearly (P < 0.001) as LP inclusion in the diet increased. Dietary LP supplementation significantly decreased (P < 0.05) heat shock protein 70, heat shock protein 90, and cortisol concentrations, with the lowest values observed at 100 mg LP/kg DM. Total cholesterol levels were not affected by LP supplementation. However, dietary LP reduced (P < 0.05) low-density lipoprotein cholesterol and triglyceride concentrations, with the most pronounced effect at 100 mg LP/kg DM. High-density lipoprotein cholesterol concentrations were significantly increased (P < 0.05) by LP supplementation, showing the greatest response at 100 mg LP/kg DM. Overall, supplementation of LP at 50 or 100 mg/kg DM improved antioxidant status and modulated the lipid profile by reducing oxidative stress markers, with the highest beneficial response observed at 100 mg LP/kg DM.
