How Livestock Learn About Foods and Locations
Utah State University Extension
So what does an animal that has just eaten learn when a person walks into its pen, catches it, and gives it a capsule containing a toxin with a balling gun? The animal will associate the person with its skin-defense system and will avoid the person in the future, but it will associate the food with nausea and avoid the food in the future. The automatic pairing of foods with feedback means that even if a person could explain to the animal that the toxin, not the food, caused the illness, the animal would still avoid the food. It is the same when we know that the flu or motion sickness, not the food, caused nausea; we still avoid the food even though we know it was not the source of nausea. The gut-defense system is designed to pair eating a food with gastrointestinal illness regardless of what the animal “thinks” caused the illness.
