By
Ongoing studies are leading scientists closer to the development of an alternative to help prevent and treat the beef industry’s costliest disease. Researchers at the Agriculture and Agri-Food Canada (AAFC) research centre in Lethbridge, Alta., are developing a probiotic to help reduce the incidence of bovine respiratory disease (BRD). Though several studies are still needed […] Read more
