The Role of Dietary Iron and Alternative Growth Promoters on the Growth Performance and Gut Microbiome of Post-Weaning Piglets
Postweaning diarrhea (PWD) is the leading cause of morbidity and antibiotic use in swine production. Dietary strategies that alleviate weaning-associated gut dysbiosis may help prevent PWD. This study evaluated the effects of dietary iron modulation alongside zinc- and copper-based alternative growth promoters on the gut microbiome, growth performance, and metal homeostasis in post-weaning piglets
