We give antibiotics to most of the meat animals on the planet on most days of their lives — and we don't give them those antibiotics because the animals are sick. We give them because, back in the 1950s, it was discovered that if you give tiny doses of antibiotics to animals — much too small to cure an infection — you will cause them to put on weight faster, which is an economic benefit to the farmer or the producer. And, then, a little while after that, it was discovered that if you gave a slightly larger dose — but still not enough to cure an infection ... what would technically be called a sub-therapeutic dose — you could protect animals from the diseases that spread in crowded barns and feedlots — those barns and feedlots becoming crowded because of this temptation to grow animals faster and faster. So that’s where we are today — all around the world.
