摘要 随机从2窝“杜长约”三元杂交仔猪中挑选12头,分成A、B、C3组,每组4个重复,公、母各半。21日龄断奶;22-26日龄,A组饲喂不舍任何豆科植物的代乳料,B、C组分别饲喂合纯化的蒸汽处理前、后β-伴大豆球蛋白的代乳料。26日龄全部屠宰,取胃、空肠中段、盲肠和结肠中的食糜,以测定消化道各部位β-伴大豆球蛋白的免疫活性。结果表明:随着消化道的延续,β-伴大豆球蛋白的免疫活性均呈下降趋势;与消化道其他部位比较起来,活性在胃和空肠下降幅度较大,到空肠中段基本丧失,从空肠中段到结肠无明显变化;整个消化道中,采食含未经蒸汽处理β-伴大豆球蛋白代乳料仔猪中β-伴大豆球蛋白免疫活性的下降幅度均小于采食含蒸汽处理β-伴大豆球蛋白代乳料的仔猪。
