     Total costs include operating costs, plus allocated overhead (hired labor, opportunity cost of unpaid labor, capital recovery of
       machinery and equipment, opportunity cost of land (rental rate), taxes, insurance, and general farm overhead).
    Notes: Coefficients of variation (CVs) were checked for the category totals: gross value of production, and feed, operating,
       allocated overhead, and total costs. All CVs were less than 25 percent.
