TTB is correct. One thing to be sure of, is that you are getting ENOUGH
mineral in those cattle. An ounce or two isn't enough consumption.
However, if you are feeding a good quality mineral, it shouldn't necessarily need to be chelated to keep cattle from having ringworm. A quality mineral enhances the immune system so cattle can take care of these little aggravating things themselves.
Interesting TTB, that you did find the chelated helped you. You know
my theory, if it ain't broke, don't fix it. Far be it from me to tell you you
don't need chelated mineral. But usually that is not the case.
We sell very little chelated mineral in this area. Just the regular mineral fed year-round does the trick here.
IMMUNE SYSTEM!!!!! That's what it's all about.
I'd be interested to have you post the tag off your mineral, horseless.
