The invention discloses feed. The feed is prepared by taking lathyrus sativus as a component of the feed for animals, in particular to a rodent, such as a rabbit, and mixing with lathyrus sativus seeds, alfalfa meal, corn, wheat bran, a rape seed cake, wheat, salt and a premix. The feed eliminates a bias of the prior art; a toxic plant seed serves as the component of the feed for the animals; and a new variety is created for raw materials of the feed for the animals.
