Natural supplement positively impact dairy calf immunity; could reduce antimicrobial use

Alliance-funded research shows purple coneflower supplementation in Holstein calves led to indicators of better immunity and anti-inflammatory properties.

Dr. Trevor DeVries, professor in the Department of Animal Biosciences at the Ontario Agricultural College (OAC) and Canada Research Chair in Dairy Cattle Behaviour and Welfare, studied 240 male Holstein calves to evaluate how purple coneflower supplementation, scientifically called Echinacea purpurea, could affect immunity markers, disease, feed intake, and growth of these calves. 

“Like humans, dairy calves are susceptible to diseases like diarrhea and respiratory problems, which can cause high levels of morbidity and mortality,” says DeVries. “We are particularly looking for ways to improve the health and welfare of male calves because they often have the added stress of transportation to another facility. This medicinal herb could improve animal health and reduce antimicrobial use in dairy and dairy beef calves.”
