It is constituted by the value of product which, during the specified period, is sold, used for HOUSEHOLD consumption, used on the farm for seed or feed, used for payments in kind or gifts, or in store at the end of the period. In calculating gross farm income, those components of OUTPUT that are not sold should be valued at market prices. For livestock, though not usually for standing crops because of difficulties of valuation, changes in the value of the stock of animals over the period are usually taken into account.
