WASHINGTON — USDA has published a proposed rule that would continue the allowance of synthetic methionine in organic poultry production but at reduced levels from the current allowable levels.
The current allowance for synthetic methionine expires on Oct. 1, 2012, and allows 4 pounds per ton of feed for laying chickens; 5 pounds per ton of feed for broiler chickens; and 6 pounds per ton of feed for turkeys and other poultry. The proposed rule would permit organic poultry producers to use synthetic methionine after Oct. 1, 2012, at the following maximum levels: laying and broiler chickens, 2 pounds per ton. . .
