Abstract

This study investigates the impact of grazing behavior and duration on the natural detoxification processes and physiological health of domestic sheep. Twenty sheep were divided into four treatments: T1 (control, no grazing), T2 (3 hours/day grazing), T3 (6 hours/day grazing), and T4 (9 hours/day grazing). Key biochemical parameters, including hormone levels, cadmium, and copper concentrations, were measured to assess detoxification efficiency and overall health improvements. The results demonstrate significant improvements in detoxification markers and animal welfare with increased grazing duration. Specifically, longer grazing periods significantly reduced cortisol levels, indicating lower stress, and reduced the excretion of cadmium, suggesting improved detoxification. Additionally, the reduced copper concentrations in sheep with extended grazing indicate better nutrient absorption and overall health. The findings underscore the critical role of grazing behavior in influencing physiological health through natural detoxification pathways, such as the glucuronide mechanism. Reduced cortisol levels in sheep with longer grazing durations suggest grazing not only provides nutritional benefits but also reduces stress. Lower cadmium levels and higher copper concentrations point to more efficient elimination of heavy metals and better metabolic function. These results highlight the importance of incorporating natural grazing practices into livestock management strategies to promote sustainable and animal-friendly farming. By optimizing grazing durations, farmers can improve the welfare and health of their sheep, leading to enhanced productivity and better environmental stewardship.
