Serum IgG profiles for calves up to 50 days varied markedly depending on the level of passively acquired immunity. A relationship between serum IgG at 5 days of age and prevalence of leg injuries (skin lesions) was found, whereas no associations were seen regarding IgG and diarrhoea or liveweight gain.
50日龄以内犊牛的血清IgG水平因被动获得性免疫水平的不同而有显著差异。研究发现犊牛5日龄时的血清IgG水平与腿部损伤(皮肤损伤)的发生率之间存在关联,而未发现IgG水平与腹泻或体重增加之间存在关联。
