If the salt/potassium has been balanced by adding salt to the feed as above, your horse should have a “normal” salt hunger and should seek extra salt when he needs it.
Here in Oz, it's generally the case, especially on farm land, that the land and therefore feed grown on it is too high in sodium, which in turn binds up and destroys other minerals(esp.potassium). Therefore it is these, not sodium that needs to be supplimented. I would say that if planning on feeding any particular mineral not naturally balanced, a feed/soil analysis &/or blood test should be done to ensure you're not throwing the system into more disarray.
Country girl, you speak with authority & detail which suggests you know exactly what you're talking about
I'm interested to know more about the salt/potassium balance & salt hunger? Never heard of this, tho I've done a lot of reading on nutrition & nutritional suppliments. Perhaps it's because I usually read Australian studies and as I've said, Oz is way high in salt, so it is rare that it needs to be supplimented separately. However, chemical farming is a huge part of the problem, raising salt levels which destroy potassium, so I would have thought it was a global problem in farming areas.
