Studies on immunoglobulins and trypsin inhibitor in colostrum and milk from sows and in serum of their piglets

Acta Vet Scand. 1979;20(1):60-72. doi: 10.1186/BF03546630.

Abstract

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.

Koncentrationen af IgG, IgM, IgA samt den specifikke so-kolostrum trypsin-inhibitor (SCTI) blev målt ved radial immunodiffusion i kolostrum- og mælkeprøver fra søer og i serumprøver fra deres afkom udtaget under hele diegivningsperioden. Alle målte variabler i både valle og serum viste en klar afhængighed af tidspunktet i laktationen. Der blev fundet statistisk signifikante positive korrelationer mellem, på den ene side, serumkoncentrationer af IgG og IgA, men ikke IgM, hos 39 diende grise, en og tre dage garnie, og, på den anden side, koncentrationer af de samme immunoglobuliner samt SCTI i deres mødres kolostrum (n = 7). Multiple regressionsanalyser viste, at niveauet af både IgG og IgA i serum fra de diende grise, en og tre dage garnie, var positivt afhængig af koncentrationen af både SCTI og IgG eller IgA i deres mødres kolostrum.
