The Food and Drug Administration has approved the removal of the weight-limit restriction on Denagard Liquid Concentrate. Pork producers are now able to use the product in pigs weighing more than 250 pounds.

Denagard is approved to treat swine pneumonia caused by Actinobacillus pleuropneumoniae and swine dysentery. Response to the treatment is usually evident in 24 to 48 hours. That’s because tiamulin, the product’s active ingredient, is readily absorbed from the gut and can be found in the blood within 30 minutes after dosing.

“Producers can now use Denagard Liquid Concentrate in animals weighing more than 250 pounds,” says Sean O’Hare, swine and poultry sales manager for the Novartis U.S. farm-animal business segment.

It should not be used in feeds for animals other than swine. The effects of tiamulin on swine reproductive performance, pregnancy and lactation have not been determined.
