"
Agricultural production […] consists of two large subsectors, animal production and crop production. Animal production includes establishments that raise livestock, such as beef cattle, poultry, sheep, and hogs; farms that employ animals to produce products, such as dairies, egg farms, and apiaries (bee farms that produce honey); and animal specialty farms, such as horse farms and aquaculture (fish farms). Crop production includes the growing of grains, such as wheat, corn, and barley; field crops, such as cotton and tobacco; vegetables and melons; fruits and nuts; and horticultural specialties, such as flowers and ornamental plants. Of course, many farms have both crops and livestock, such as those that grow their own animal feed, or have diverse enterprises."
