The protective effects of Butipearl(TM) Z during heat stress as measured through in vitro studies with swine intestinal epithelial cells and an in vivo swine trial

An abstract of a study by Mani et al that examines the protective effects of Butipearl Z during heat stress (HS) as measured through in vitro studies with swine intestinal epithelial cells and an in vivo swine trial is presented. During the growth phase, there was a trend for higher ADFI and ADG in pigs fed the BPZ treatment (P < 0.1). During HS, ADG and Gain:Feed were statistically higher in BPZ group (P < 0.05) and ADFI was numerically higher. Additionally, macromolecule permeability in the ileum and colon was numerically lower and villus height and villus height to crypt depth ratio were numerically higher which indicates a more intact tight junction in the BPZ group. The data provides evidence BPZ may mitigate the negative effects of HS.
