The IgG-concentration was determined in serum of 3 pregnant sows before and after partus and in colostrum of 7 sows 0–6 days post partum. The IgG-concentration decreased in serum before partus and increased after partus. The lowest value (1.5 g/100 ml) was observed at partus. The results indicate that IgG is transmitted from serum to colostrum. The concentration of IgG in colostrum was found to be 2.1–10.4 g/100 ml at partus. The concentration decreased very fast during the first day post partum. During 3–6 days post partum the IgG concentration was rather constant (0.3–0.5 g/100 ml). The importance of the results for the passive immunization of piglets is discussed.
在3头怀孕母猪分娩前后的血清以及7头母猪产后0至6天的初乳中测定了IgG浓度。分娩前血清中IgG浓度降低,分娩后升高。在分娩时观察到最低值(1.5克/100毫升)。结果表明IgG从血清转移至初乳。初乳中IgG浓度在分娩时为2.1至10.4克/100毫升。产后第一天浓度迅速下降。产后3至6天IgG浓度相当稳定(0.3至0.5克/100毫升)。讨论了这些结果对仔猪被动免疫的重要性。
