The effect of beta carotene on disease protection and humoral immunity in chickens was investigated in comparison with the effect of other lipid-soluble antioxidant vitamins, vitamin E and A, which are both proven immunoenhancers and contributors to disease protection. Beta carotene alone was not as effective as either vitamin in protecting chickens from Escherichia coli infection, nor did it significantly enhance humoral immunity. In combination with vitamin E, however, beta carotene significantly increased disease protection and reduced hepatomegaly caused by E. coli infection.
研究了β-胡萝卜素对鸡疾病保护和体液免疫的影响，并与其他脂溶性抗氧化维生素（维生素E和维生素A）的作用进行了比较，维生素E和维生素A均已被证实具有免疫增强作用且有助于疾病保护。单独使用β-胡萝卜素在保护鸡免受大肠杆菌感染方面不如这两种维生素有效，也未显著增强体液免疫。然而，与维生素E联合使用时，β-胡萝卜素可显著提高疾病保护能力，并减轻大肠杆菌感染引起的肝脏肿大。
