Effect of xylanase and live yeast supplementation on growth performance, nutrient digestibility and gut microbiome diversity of pigs

Effect of Xylanase (Xyl) and live yeast (LY) supplementation on gut microbiome composition, growth performance and nutrient digestibility of weanling pigs was determined. A total of 180 weanling pigs were assigned to 5 treatments from weaning to market. Treatments were designated based on whether Xyl, LY or their combination were fed in the first two weeks postweaning or thereafter until finishing at d 141 postweaning. Treatments were (d 1- 15; d 15-141): control-control, control-Xyl, Xyl-Xyl, LY-Xyl, Xyl+LY-Xyl. Xylanase was added at 16,000 BXU/kg and LY at 1 kg/t. Pigs fed with LY and LY+Xyl from d 0-15 had greater body weight (BW) and average daily gain (ADG) at d 15 compared with control (PThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
