Study objectives were to determine the effects of dietary live yeast ( strain CNCM I-4407; ActisafHR+; 0.25g/kg of feed; Phileo by Lesaffre, Milwaukee, WI) on growth performance and biomarkers of metabolism and inflammation in heat-stressed and nutrient-restricted pigs. Crossbred barrows ( = 96; 79 ± 1 kg body weight ) were blocked by initial BW and randomly assigned to one of six dietary-environmental treatments: 1) thermoneutral () and fed ad libitum the control diet (), 2) TN and fed ad libitum a yeast containing diet (), 3) TN and pair-fed () the control diet (), 4) TN and PF the yeast containing diet (), 5) heat stress () and fed ad libitum the control diet (), or 6) HS and fed ad libitum the yeast diet ().
