Worming A Pregnant Mare

What is safe to use to worm my pregnant mare? And how often should I do this?

Most horse wormers are safe to use on a pregnant mare throughout their pregnancy. However you should check the label or product information prior to use as it will say whether or not it has been tested as safe for use in pregnant mares.

Wormers that are advised by the manufacturer to be as safe for use in pregnant mares include (but not limited to) Equimax Elevation, Equimax, Equest Plus Tape Gel, Razor, Imax Gold, Promectin Plus, Ammo and Strategy T.

When it comes to worming pregnant mares they should be treated as normal throughout their pregnancy. They should be kept on a regular worming rotation (every 6-8 weeks or as per the recommendations on the wormer being used) You should try to worm them about 2 weeks prior to foaling and try to limit the stress involved during the process. You should then worm both the mare and foal again when the foal is about 6-8 weeks old.
