    Is there a list of examples for extensive free choice mineral feeding?

    • Casie says:

      Hi Julie–do you mean the different free-choice products which are available?

      • Julie says:

        Not so much the product (although those are welcome too).

        In the article it says: “Avoid unbalanced single minerals or combinations of just a few minerals unless they are offered as a part of an extensive free-choice system (and are palatable for that purpose).”

        So I am wondering, if you make an extensive free-choice system for the horses – which minerals (or maybe examples of products) can be fed?

        • Casie says:

          That’s can be a tricky question, Julie. It depends on what’s lacking in your specific pasture or hay. (I get my hay tested so I know what’s lacking.) The most common deficiencies are copper, zinc, and sometimes phosphorous. Occasionally calcium and pretty much never iron. Also, salt always needs to be available as there’s not enough in grass or hay. Advanced Biological Concepts (ABC) has some good free-choice minerals. Pricey, but good.

    Hi Casie, I’m curious…If my hay is lacking in Phosphorous, magnesium, zinc and copper would you suggest it is best to just put out buckets of these four minerals along with salt and let the horses decide which and how much of each they want to eat?

    • Casie says:

      Hi Cyndi–I think that might be a good idea to try. I know ABC (Advanced Biological Concepts) sells the individual minerals which you could use for that.

    My issue is that my horse (diagnosed with PPID) refuses to eat minerals, and only will eat plant based supplements. Even in pelleted form, if is is just the mineral and not plant based she won’t eat it. To be honest I can’t blame her, so I am interested in finding the best forms of plant based trace minerals to help get her on track with her PPID. She is boarded with multiple hay suppliers, so testing isn’t going to help. Any suggestions?

      Hi Heather, I’d suggest trying kelp (I order from or herb-based minerals from
