Sweet potato (Ipomoea batatas (L.) Lam.) is a plant grown for its tuberous roots in tropical, subtropical and warm-temperate regions. While the tubers are the main agricultural product derived from the sweet potato crop, the vegetative parts are a very valuable feed for livestock. Sweet potato vines and foliage can be fed to cattle, sheep, goats, pigs and rabbits. (https://www.feedipedia.org/node/551)
