 From the Ag Information Network, this is your agribusiness update. U.S. ag groups are reacting to the USDA's proposed Packers in Stockyards rule titled Fair and Competitive Livestock and Poultry Markets. National Cattlemen's Beef Association Vice President Ethan Lane, though, calls the proposals a direct attack on cattle producer profitability. He says USDA sends a clear message that cattle producers should not derive any free market benefit but be paid one low price regardless of quality, all in the name of so-called fairness.
