What are they and what are they meant to do? I just assumed it was a type of bolus for minerals but from the above they're a bit more specialised? Something to do with ketosis??
Monensin alters the rumen flora to improve feed efficiency. I don't think it's a hormone but it's a bit close to being an antibiotic. It's widely used as a feed additive in most countries outside Europe.
