Moth and Minerals and Water

When my new Fell Pony stud colt Globetrotter Moth arrived from England, I was pleased that he was content with the hay I had to feed him, and he learned quickly where water was available. I was also pleased at how sensible he was about going into the shed in his paddock where the free choice salt and minerals are available. I wasn’t too surprised then that the first few days into his life here went well. And then one day, he wasn’t right.

I checked him before dark, and he was lying down and uninterested in a handful of green grass. Not a good sign! I went into emergency mode and within a few hours, he was back to normal after several heavy doses of probiotics. Then I began wondering what had happened. I concluded it had to do with water and minerals.

For most of the year, the waterers for the ponies are fed by spring water. Sometimes, though, well water is in the pipeline when the spring can’t keep up with the number of cattle and other animals on the ranch’s water system. The spring water has been tested as the best quality in our area; the well water is heavier in minerals. I have noticed that my ponies change how they use their free choice minerals when the water is switched from one type to the other.

On the day when Moth didn’t feel well, the water had been switched from the spring to the well. I realized he hadn’t had time to learn to use the free choice minerals to keep his system balanced when the mineral content of the water changed. Sure enough, while Moth had been willing to go into the shed where the mineral feeders are, he hadn’t used them. I made sure he had spring water as well as well water as he recovered.

A few weeks later, after it was clear that Moth was using the minerals, I weaned him back onto well water only when I also saw him drinking it regularly. I checked him several times, and sure enough he did fine. I was very thankful with how sensible he was about learning to use the minerals. And I was thankful for free choice minerals and that the ponies use them to keep their systems balanced. I can’t begin to adjust their mineral supplements as well as they can do it for themselves.

Minerals and the Moon

Many years ago, I read an article by Dr. Doug Hammill, DVM about salt and minerals for equines. (1) His recommendation was for the salt and minerals to be provided loose and free choice: loose because equine tongues are not coarse enough to get what’s needed from a block and free choice to allow the equine to get what they need when they need it. Weather, exercise, change in hay or water all can affect the mineral combinations that equines need.

Providing minerals loose and free choice allows ponies of all ages to get what they need when they need it.

I have always felt fortunate that my first mentor in all things equine told me to provide minerals and salt loose and free choice. Over the years, as I replenish minerals in the various sheds that my ponies use, I have watched how their use of minerals changes. Usually I can pin a change on something, whether it’s a change in weather or a change in feed, for instance. An article in the Stockman Grassfarmer, however, suggested an influence on mineral uptake I hadn’t pondered before.

Joel Salatin, whom you may know for his long work with pastured poultry, had traveled to New Zealand to talk to farmers and stockmen about grazing. In one of his conversations, a stockman pointed out to him that the influence of the moon on mineral uptake isn’t appreciated. That’s definitely something I’ve never considered! The stockman made their observation in the context of plants taking up minerals that grazing animals then take up. The moon is known to influence water, and since many minerals are water-soluble, it makes sense there could be a connection between the moon and mineral uptake by plants and by extension by grazing animals. Here’s another good reason to provide minerals in a way that equines can get what they need when they need it. I certainly can’t keep track of how the moon might influence what they need or don’t!
