FEED•LOT  December 2017 15 levels compared to a control group. On day 29, animals were adminis- tered a challenge to stimulate an immune response. Throughout the trial cytokine production was m easured, which is a protein pro- d uced by the immune system. During the trial, when compared with the control, cattle who re- ceived S. c. boulardii CNCM I-1079 showed: • A decreased production in their cytokine profile, possibly sug- gesting a more effective or effi- cient immune response. • A decrease in the stress hor- mone cortisol, which indicates cattle were able to overcome the immune challenge at an effec- tive rate. • Had a lower body temperature when compared to the control animals. "When an animal is challenged with a pathogen there is a fever or febrile response, and that takes a massive amount of energy," Dr. Schmidt says. "For an animal to in- crease its body temperature by 1- degree Celsius, it's estimated it takes about a 13-percent increase i n metabolic energy use." S teers supplemented with S. c. boulardii CNCM I-1079 had a much lower body temperature after the challenge. This suggests animals may be spending less energy fight- ing an immune challenge — allow- ing it to return to production cycle more quickly, Dr. Schmidt explains. "This shows interesting benefits that could be significant for the beef and dairy industries," Dr. Schmidt says. "It appeared the feed additive allowed animals to conserve energy and use less energy when mounting the febrile response. This could be a massive tool for us in the industry as we continue to find alternative solutions to minimize illness and other challenges."
