Eucommia Ulmoides Flavones as Antibiotic Alternatives in a Low-protein Diet Improve Growth Performance and Intestinal Health in Weaning Piglets

Background Eucommia ulmoides flavones (EUF), have been demonstrated to attenuate the inflammation and oxidative stress of piglets. This study was designed to test whether EUF could be as an antibiotic alternative to support growth performance and maintain intestinal health in weanling-piglets. Weaned-piglets (n = 480) were assigned into 3 groups and fed with a low-protein basal diet (NC), or supplementation with antibiotics (PC) or 0.1‰ EUF (EUF). Blood, intestinal contents and intestine were collected on d-15 and d-35, respectively. Results The results showed that the body weight on d-35, average daily gain and gain : feed from d 15 to d 35 and d 0 to d 35 in piglets of PC and EUF treatments were higher than (p p p p p coliform bacteria and diarrhea index in weanling piglets.
