Antibodies of the secretory IgA type against cow's milk proteins were consistently found in human milk. With the assumption that such antibodies can help to prevent or at least diminish the contact between native cow's milk proteins and the lymphoid system of babies on mixed feeding, the levels of antibodies of various immunoglobulin classes against bovine milk proteins were measured in different groups of babies. Those on artificial feeds who had been on mixed feeding of human milk and cow's milk for less than 1 week had significantly higher levels of IgG antibodies to cow's milk proteins than those who had been on mixed feeding for a period longer than 3 weeks.
人乳中一直能发现针对牛奶蛋白的分泌型 IgA 类抗体。假设此类抗体有助于预防或至少减少天然牛奶蛋白与混合喂养婴儿淋巴系统之间的接触，于是对不同组婴儿中针对牛乳蛋白的各类免疫球蛋白抗体水平进行了测定。人工喂养且母乳与牛乳混合喂养不足 1 周的婴儿，其针对牛奶蛋白的 IgG 抗体水平显著高于混合喂养 3 周以上的婴儿。
