Boosting Broiler Health and Productivity: The Impact of in ovo Probiotics and Early Posthatch Feeding with <i>Bacillus subtilis</i>, <i>Lactobacillus fermentum</i>, and <i>Enterococcus faecium</i>.

ABSTRACT: In ovo administration of probiotics has the potential to enable the early colonization of the gut microbiota, providing health benefits from the onset of life. This study aimed to assess the impact of in ovo probiotic inoculation combined with early posthatch feeding on intestinal development and colonization by Campylobacter spp., immune system development, and the final production performance of chickens. On the 18th day of incubation, Bacillus subtilis, Lactobacillus fermentum, Enterococcus faecium, or physiological saline (control) was administered to Ross 308 eggs in ovo, and chicks had immediate access to feed and water upon hatching. On the 7th, 21st, and 35th days after hatching, samples of tissues were taken for histomorphometric analysis. Campylobac
