Dietary yeast hydrolysate supplementation improved the growth performance of weaned piglets before LPS challenge. A Schematic of the feeding experiment and LPS challenge. B–D Effects of dietary YH supplementation on average daily feed intake (ADFI), average daily gain (ADG) and the ratio of feed intake to gain (F/G) of weaned piglets. Control, piglets were fed with a basal diet; YH, piglets were fed with a YH containing diet, 5 g/kg. ^*P < 0.05, ^**P < 0.01, compared with control group
