Fig 2. Effects of maternal antibiotic (ATB) treatment on protein expression of inducible heat shock proteins (relative to β-actin) in colonic tissues of offspring between 14 and 42 days of age (weaning at day 28).

(LSmeans and SEM, n = 10–12 per treatment and age). A. HSP27. Maternal ATB treatment significantly increased offspring colonic HSP27 levels between d14 and d42 of age (P < 0.001). B. HSP70. Maternal ATB treatment significantly increased offspring colonic HSP70 levels between d14 and d42 of age (P < 0.01). Western blot bands from representative pigs are shown for HSP27 and β-actin (A) and for HSP70 and β-actin (B).
