Compound organic acid could improve the growth performance, immunity and antioxidant properties, and intestinal health by altering the microbiota profile of weaned piglets.

Weaned piglets face challenges due to their underdeveloped digestive system, resulting in high gastrointestinal tract pH and insufficient enzyme secretion. To address this issue, we found supplementing piglet diets with 3,000 mg/kg of compound organic acid positively impacted the immune and antioxidant levels of piglets, promoted their intestinal health, improved nutrient digestibility, and enhanced their overall growth performance. These benefits were attributed to the regulation of intestinal microbiota by the compound organic acid. By improving piglet health and growth, this research offers a potential solution to the challenges of piglet weaning stress.
