Crops grown for agricultural purposes are mostly produced for animal feed.

Crops are either grown as summer or winter supplementary feed for stock and generally consumed on the farm where they are produced. Alternatively they are harvested and made into silage or balage for later use (i.e., when grass growth is slow in winter) or for sale. Crops commonly grown include maize and cereals (barley, oats) for silage, field peas, and other crops such as swedes, kale, and turnips as stock food.
