在养猪生产中防控玉米霉菌毒素的研究进展

我国是玉米生产和使用大国,大部分玉米则用于饲料原料,一般情况下玉米在猪饲料原料比例为60%以上,饲料原料的霉变和霉菌毒素污染主要是玉米问题。玉米霉变与霉菌毒素污染受到玉米水分含量、完整度、干燥方法、贮存条件、地区和气候等影响。玉米霉菌毒素含量超标对猪将引起一系列严重的生理和生物毒害,如致癌性、致突变性、致畸胎性(褚曲霉毒素)、致雌激素样、免疫毒性、肾毒性、肝毒性、神经毒性等[1]。本文就玉米用于养猪生产中霉变防控问题做一简要综述。

玉米霉菌毒素对猪的危害和防治措施

霉菌毒素是一种存在于原料与饲料中的抗营养因子，易出现在饲料加工、运输、贮存等过程中，严重危害了动物的健康。本文在介绍霉菌及其毒素种类、危害、中毒特征的基础上，阐述霉菌毒素的防治措施。

Effects of Mycotoxin from Maize on Immune Response of Vaccine for Piglets

[Objective] The aim of this study was to investigate the effects of mycotoxin from moldy maize on immune response of piglets.[Method] ELISA method was used to determine the content of Aflatoxin B1 and ochratoxin A in maize; after the piglets were fed with the moldy maize,the corresponding antibody titers in the serums of piglets were measured.[Result] Antibody levels of tested group were obvious lower than that of the control,while the histological section of immune organs also suggested that mycotoxin could significantly inhibit the immune response of piglets.[Conclusion] Mycotoxin in maize had important effects on the internal organs and immune response of piglets.
