11 primary food commodities of plant origin (ccpr) 051 straw, fodder and forage of cereal grains and grasses, except grasses for sugar production (including buckwheat fooder) (as/af) (ccpr) The straw, fodder and forage of cereal grains are derived from various plants of the grass family (Gramineae). Cereal grains are grown to a limited extent as a forage crop. The immature crop is fed to livestock animals as succulent forage or as silage. The cereal grain crops are mainly grown for human food or raw material for preparing food products. The "waste" parts remaining after harvest of the grain kernels (stems, stalks, leaves and empty ears) are extensively used and distributed for animal feeding purposes, in the form of dry fodder or straw. Several other species of the grass family are exclusively grown as forage crops. These crops are either used for grazing or are prepared for wholesale or retail distribution in the form of grass silage (in general one or more cuttings from immature plants), as artificially dried grass or as hay. The entire conimodity may be consumed by livestock animals. requires discussion
