When should I de-worm my cattle and with what?

Beef Cattle March 06, 2008 Print Friendly and PDF
In some areas of the Midwest and Southwest, cattle should be de-wormed in the fall to rid animals of worms that become embedded in the stomach lining. For worm and grub control, using a pour-on containing moxidectin or ivermectin during early summer will control both parasites and give several weeks of horn fly control also. De-worming strategies will vary tremendously from one environment to another. Producers should visit with local Cooperative Extension educators concerning de-worming strategies that have been successful in their area. In some regions, de-worming calves may be more cost effective than de-worming just the cows. In some areas, anthelmintics may need to include fluke control ingredients, whereas in other areas, these would be unnecessary.
