Wondering about antibiotics in cattle feed?
Jean L Clavelle

There has been much discussion on antibiotics that go into livestock production and their influence on antibiotic resistance. Antibiotic resistance is so incredibly complex that not even the scientific community fully understands all of the causative factors. We don’t have the space to tackle that topic here but I would like to chat about antimicrobial use in cattle production - in particular a group of medications called ionophores - as they are a widely used tool by cattle producers and wildly misunderstood by the general public.
So let’s start from the beginning. Cattle are considered “ruminants”, a class of animals which have not just one stomach but four (yes you read that right - 4 stomachs!). Of the four compartments, the Rumen is the first and largest, and the main digestive centre. The rumen is filled with billions of bacteria that are able to break down grass and other coarse fibrous materials (such as hay and straw) that animals with only one stomach (including humans, chickens and pigs) simply cannot digest.
