Therefore, this study aims to investigate the regulatory effects of Lactobacillus johnsonii on growth performance and intestinal health of broilers infected with A. galli. In this study, 80 one-day-old broilers were randomly assigned to a 2 × 2 factorial arrangement of treatments, which included two levels of L. johnsonii (0 or 1 × 10⁹ CFU/mL) and two infection statuses (A. galli challenge or no-challenge).
