Probiotics and gut health: linking gut homeostasis and poultry productivity

The use of probiotics in poultry production has increased rapidly, and this movement been promoted by global events, such as the prohibition or decline antibiotic growth promotants feeds. There a persistent search for alternative feed additives, have shown that they can restore composition gut microbiota, produce health benefits to host, including improvements performance. Probiotics potential increase productivity poultry, especially flocks challenged stressors. However, outcomes probiotic not always consistent. is an increasing demand well defined products be applied strategically, currently, research focusing on delineating their mechanisms action contribute improved efficacy. In particular, involved maintenance protection intestinal barrier integrity role microbiota are being extensively investigated. It modulate immune pathways both directly through interactions with microbiota. These key maintaining homeostasis function, improving efficiency. Research demonstrated execute effects multiple mechanisms. present review describes recent advances poultry. focuses current understanding chickens, how it assessed supplementation diets diets. cellular molecular structure function described. also highlights important factors influence efficacy bird
