A novel low-protein diet feeding strategy with reduced amylose/amylopectin ratio: effects on growth performance, gut health, and behavior in nursery pigs

This study aimed to evaluate a comprehensive feeding plan for the post-weaning phase based on a low CP diet. The protocol comprised two phases. The first phase (d0 to 21) aimed to improve intestinal health by reducing dietary CP. The second phase (d21 to 63) still involved a low CP diet while improving the synchronization between AAs and glucose availability by lowering the AM/AP ratio. The feeding plan's effectiveness was assessed using parameters such as intestinal health (fecal microbiota and metabolome), growth performance, behavior, and lesion occurrence in pigs.
