Moultrie -- You may recycle a few products at home, but folks at the Expo learned that cows are the ultimate recyclers.
Because of their unique digestive system, cows can eat a lot of by-products that would otherwise end up in the trash.
Not only can they digest old bread and other baked goods, but brewers' grain, a by-product of beer manufacturing, is good for a cow's diet.
"All that product is fed to dairy cows because they can digest it they can utilize it, so it doesn't go into a landfill. It doesn't have to be land applied and cause any water quality issues, there's a lot of other products as well," says John Bernard of the UGA-Tifton campus.
Cows can also eat distillers' grain a by-product of ethanol. Their manure is also recycled into fertilizer.
