A feedlot is a place where cows (and sometimes other animals like pigs) go to eat and grow big and strong, kind of like a big cafeteria for cows!
At the feedlot, the cows are given a special diet that is made up of different kinds of food like corn, soybeans, and hay. This special diet helps them grow big and strong really fast.
The cows live in big pens, kind of like a big playground, with plenty of room to run around and play. They also have access to fresh water to drink whenever they want.
The cows stay at the feedlot until they are grown up and plump enough to be sent to the meat processing plant. This is where they will be turned into things like burgers and steaks that we can eat.
So, a feedlot is a place where cows go to eat a special diet and live in pens until they are ready to be turned into food.
