    Default Worming by Weight Question

    I recently had my gelding weighed, he came in at a whopping 1304 lbs, much to my surprise. I have always given him a full tube of whatever wormer was next in the rotation, but since most tubes are for a 1250lb max horse , do I need to give him some from another tube?

    Yes!

    I have two horses to take care of and one is smaller so doesn't need the whole tube and fortunately, that makes enough for the other bigger guy!

    .

    Welcome to my world. (My adult Percherons and Belgians get at least two tubes each.)

    Since most OTC wormers are tested safe at several times the suggested dose, and under-dosing can lead to resistant parasites, I only split tubes in half. Over 1000-1200# (depending on the wormer) gets a tube and a half. Over a ton gets two tubes. Only have one flirting with needing 2 1/2 right now.

    I think this is one reason for some of the resistance that's been developing in worms. Most people consistently under-dose by weight, and do it too frequently.

    Consider Ivercare -- doses up to 1500 pounds.
    Nothing with horses is ever easy or cheap. And if it is, you're doing it wrong. They always rip out part of your soul when they leave. I guess that's how they find us later.

    Yes you are under dosing.

    Ditto what Dave M and Alibi says. Worm more.

    Only if you were worming a young (under 2 yr old) I would never worm with Quest, if so ONLY FOR THEIR WEIGHT.

    I have horses who are 1k and I always do the entire syringe which is 1250. Even if I have one who is 900#'s whole tube.

    Worm worm baby.
