Vitamin E is a critical fat-soluble antioxidant that plays a significant role in enhancing the antioxidant status and immune function in poultry and swine production systems (Surai, 2002). In poultry, supplementation with vitamin E has been shown to improve the activity of antioxidant enzymes such as superoxide dismutase and glutathione peroxidase, thereby reducing oxidative stress and cellular damage (Khan et al., 2015). Similarly, in swine, dietary vitamin E enhances plasma vitamin E levels, leading to increased resistance against oxidative challenges encountered during stress periods like transportation and weaning (Yin et al., 2013). Vitamin E also modulates immune responses by promoting lymphocyte proliferation, antibody production, and cytokine synthesis, which collectively improve disease resistance (Miller et al., 2004).
In large-scale production, adequate vitamin E supplementation correlates with improved growth performance, feed efficiency, and overall health status of animals (Huang et al., 2010). The antioxidant effect of vitamin E is particularly critical in reducing lipid peroxidation in cell membranes, which is vital for maintaining cellular integrity under intensive production conditions (Surai & Fisinin, 2014). Moreover, vitamin E supplementation has been linked with enhanced vaccine responses, indicating its role in supporting adaptive immunity (Kumar et al., 2016). However, the efficacy of vitamin E depends on dose, source, and interaction with other nutrients such as selenium (Pappas et al., 2014). Excessive supplementation, on the other hand, may lead to oxidative imbalance or nutrient antagonism, emphasizing the importance of optimal dosing (Yin et al., 2013). Overall, strategic vitamin E supplementation in poultry and swine diets improves antioxidant defences and immune competence, thereby supporting animal health and productivity at a commercial scale (Surai & Fisinin, 2014).
