These contracts specify who supplies the production inputs, the quality and quantity of the commodity to be produced, and the compensation for the producer. Under some livestock production contracts, the farmer is paid to provide housing and care for the animals until they are ready for market, but the contractor actually owns the animals. In 1997, according to the USDA, about 70% of the value of poultry production was under production contracts, 33% of hogs, and 14% of cattle. See marketing contract.
