GLZ treatment alleviates epithelial cilia shedding and pneumonia and increases immunity in weanling piglets. (a) Representative H&E stains of trachea, bronchus, and lung of weanling piglets with sham, TAB, and GLZ treatments at the 10th week of age. Epithelial cilia were fragmentary in the tracheal and bronchial tissues of the sham group but were complete in the TAB and GLZ groups (marked with arrows); scale bar = 30 μm. In the lung tissue, pneumonia was severe in the sham and TAB groups but was not observed in the GLZ group; scale bar = 150 μm. Enlarged views of the lung tissue are shown in the lower left corner; scale bars = 30 μm. (b) Comparisons of IgA, IgG, and IgE in the blood of weanling piglets with sham, TAB, and GLZ treatments at the 10th week of age. Weanling piglets with GLZ treatment showed significantly higher IgA and IgG but significantly lower IgE than those with sham and TAB treatments. All data are shown as mean ± standard error of mean (SEM) (**p < .01, *p < .05, two‐way ANOVA followed by Student–Newman–Keuls multiple comparison posttest)
