大豆主要抗原蛋白对仔猪肠道致敏反应的研究

大豆蛋白中存在的抗原物质,影响了大豆及后期加工成品在出生不久的幼龄动物的饲料配制中的广泛使用。作为仔猪主要蛋白日粮来源,大豆中存在的抗原物质对断奶仔猪生长性能有极大的危害。长期以来,学者们已对大豆抗原对仔猪的致敏机理做了深入研究,消化道作为营养物质消化吸收的重要场所是引起幼龄动物过敏反应的关键。本文从大豆主要抗原蛋白对仔猪肠道形态、营养物质消化率、免疫系统的影响以及引起仔猪肠道致敏的原因进行分析。以期为日后研究大豆抗原蛋白致敏机理和指导合理配制仔猪日粮提供参考。

Study on Gut Allergenic Responses of Soybean Major Antigen Protein

The presence of antigenic substances in soy protein greatly affects the widespread of soybeans and post-processed finished products in the preparation of feed for small newborn animals.As a piglet diet,the presence of antigens in soybeans have a significant impact on the performance of weaned piglets.For a long time,scholars have done a deep research on the sensitization mechanism of soybean antigens to piglets.The digestive tract,as an important place for digestion and absorption of nutrients,is the key causing the allergic reaction in young animals.This paper summarizes the main antigenic protein of soybean on piglet intestinal morphology,nutrient digestibility,immune system and cause of piglet intestinal sensitization.It would provide a reference for the future research on sensitization mechanism of soybean antigen protein and rationally formulating piglet ration.
