The concentrations of IgG, IgM, IgA and the specific sow colostrum trypsin inhibitor (SCTI) were measured by radial immunodiffusion in colostrum and milk samples from sows and in serum samples from their offspring during the suckling period. A clear time dependence was found for all the measured variates in both whey and serum. Statistically significant positive correlations were found between, on the one hand, concentrations of IgG and IgA, but not IgM, in sera from 39 suckling piglets 1 and 3 days old, and, on the other hand, concentrations of the same immunoglobulins and of the trypsin inhibitor in maternal colostrum (n = 7). Multiple regression analyses showed that at day 1 and day 3 the levels of both IgG and IgA in serum samples from the suckling piglets were positively influenced by both the SCTI and the IgG or IgA contents in maternal colostrum.
通过放射免疫扩散法测定了母猪初乳和乳汁样本以及其后代哺乳期间血清样本中IgG、IgM、IgA和特异性母猪初乳胰蛋白酶抑制剂（SCTI）的浓度。在乳清和血清中，所有测定变量均呈现出明显的时间依赖性。一方面，在39头1日龄和3日龄哺乳仔猪的血清中，IgG和IgA（而非IgM）的浓度与另一方面母体初乳中相同免疫球蛋白和胰蛋白酶抑制剂的浓度之间存在统计学上显著的正相关（n = 7）。多元回归分析表明，在第1天和第3天，哺乳仔猪血清样本中IgG和IgA的水平均受到母体初乳中SCTI以及IgG或IgA含量的正向影响。
