The U.S. Food and Drug Administration (FDA) has approved a label change for Paylean, a Type A medicated feed article for swine.

The new approval permits Paylean to be fed to pigs weighing at least 150 lb. during their final 50 lb. to 90 lb. of gain regardless of market weight. Prior to the change, the label allowed the use of Paylean in pigs weighing up to 240 lb.

The new label (available at www.elanco.us or 800-428-4441) also stipulates Paylean be fed between 4.5 grams to 9 grams/ton of feed in a complete ration containing at least 16% crude protein. The label also notes that recent clinical registration data suggests no statistical difference between the effects of the 4.5- and 9-gram level. Also, the 18-gram/ton feeding level has been removed.

The change to the Paylean label provides increased marketing flexibility for producers seeking to match packer weight preferences, according to Elanco. It also reaffirms the product’s efficacy at the 4.5- and 9-gram level when fed to any market weight.

Paylean has a zero withdrawal time prior to slaughter.
