摘要: The aims of this study were to investigate the effect Saccharomyces cerevisiae var. boulardii CNCM I-1079 (SCB) or Lactobacillus acidophilus BT1386 (LA) on (1) innate immune response, (2) markers acute-phase reaction, and (3) gene expression rumen ileum tissues Holstein calves. Forty eight calves (∼5 d old) randomly allocated four treatments as follows: control (CTRL) fed milk replacer followed by starter feed, CTRL supplemented with SCB in LA (4) antibiotics (ATB; chlortetracycline neomycin milk, feed). Tumor necrosis factor α (TNF-α) decreased (P < 0.05) day 66 (post-weaning) for ATB-treated There no treatment effects production interferon γ (IFN-γ) interleukin 6 (IL-6) proteins TLR4, TLR6, TLR9, TLR10, CLDN3, MUC1, MUC20 genes. Calves had a greater oxidative burst at w...
