Effects of MLP on pathological evaluation and inflammatory response of laying hens challenged with LPS. A Pathological evaluation of uterus. Hematoxylin and erosion (H&E) staining, 200× magnification (n = 6). Black arrows indicate inflammation and red arrows indicate atrophy of the gland. B Comparison of pathological analysis score of uterus. C Plasma inflammatory cytokines. D The expression of immune-related genes of uterus. Values were means and standard errors, different letters denote significant differences among different groups (P < 0.05). CN, Basal diet; CN-LPS, Basal diet + LPS; MLP-LPS, Basal diet + MLP + LPS
