There is a lot of overkill, but the USDA regulates very little except labeling with
regard to horse feeds.

Gwen, feeding high Ca may cause the imbalance. I'm don't feel I have a good handle on
this. There was a thread a month or so ago about the problems with excessive Ca
feeding. I was going to follow up with some additional questions but wanted to reread
everything first. Now those messages are buried in a IE file that is difficult to
access without IE ... but that is another story :(. I will eventually get to them, so
stay tuned.

Selenium is one of those nutrients that has a relatively narrow range between necessary
and toxic. The results are serious. White muscle disease with too little and blind
staggers with too much.

Depends on the vitamin. Some are toxic at high doses. But high Ca or P is not likely
to kill a horse (as long as Ca/P is not too low). It just may cause other problems,
especially for endurance horses.
