Vitamin E is an essential nontoxic fat‐soluble micronutrient whose effects on livestock performance and products can be attributed to its antioxidant and nonantioxidant properties. Although it is needed in small quantity in the diet, its roles in livestock production are indispensable as it is required in boosting performance, nutritional qualities, and yield of animal and animal products. The dietary or oral supplementation of vitamin E is essential in reducing lipid oxidation in muscle, egg, and dairy products as well as lowering cholesterol concentrations and improving antioxidant status of livestock. Evidence has shown that bioavailability of vitamin E–enriched animal products could serve as an invaluable nutritional benefit to consumers; especially those in regions of limited resources where vitamin E deficiencies pose a risk that may be detrimental to some cellular activities of the body and on human health. It is therefore important to redirect research on the impact of vitamin E supplementation as antioxidant on livestock performance and animal products.

维生素 E 在动物和动物产品中的多功能活性：综述。

维生素 E 是一种必需的无毒脂溶性微量营养素，其对牲畜性能和产品的影响可归因于其抗氧化和非抗氧化特性。尽管饮食中需要少量，但它在畜牧生产中的作用是不可或缺的，因为它是提高动物和动物产品的性能、营养质量和产量所必需的。膳食或口服补充维生素 E 对于减少肌肉、鸡蛋和乳制品中的脂质氧化以及降低胆固醇浓度和改善牲畜的抗氧化状态至关重要。证据表明，富含维生素 E 的动物产品的生物利用度可以为消费者带来无价的营养益处；尤其是那些资源有限的地区，那里缺乏维生素 E 会带来可能对身体某些细胞活动和人体健康有害的风险。因此，重要的是重新研究维生素 E 补充剂作为抗氧化剂对牲畜生产性能和动物产品的影响。
