With the rapid development of intensive farming, factors such as high temperature, harmful gases, high-fat and high-protein diets, and changes in feeding methods have become causes of oxidative stress in animals. Studies have shown that oxidative stress decreases livestock feed intake and slows growth in animals, thereby affecting the quality of livestock products. Antioxidants and micronutrients are commonly added to animal feed to reduce the effects of oxidative stress. Since the progress in nanotechnology, nanovitamins have gained extensive recognition due to their novel qualities, including a high level of adsorption capacity and low toxicity. Therefore, the present study compared the effects of dietary supplementation with different sources of vitamin E (regular, RVE vs. nano, NVE) and varying inclusion levels on the growth performance, antioxidant capacity, VE absorption sites, and pharmacokinetics in AA broilers. The results indicated that supplementing broiler diets with NVE provides superior antioxidant benefits compared to RVE. This improvement is attributed to the enhanced absorption efficiency and extended half-life of NVE, both contributing to increased antioxidant performance of broilers.
