Now here is another interesting fact about both Crystalex and Sweetpro.
They both say:
Crystlex: "WARNING: This product, which contains added copper, should not be fed to sheep or any species that have a low tolerance to supplemental copper."
Sweetpro: "
CAUTION: Contains 600 ppm copper • DO NOT FEED TO SHEEP • Do not use in association with another feed containing supplemental selenium."
Q, Why is that? Why are they both adding additional copper?
A. Because it is a well known fact that excess sulfur blocks the absorption of copper and they are trying to correct a copper deficiency by adding more copper.
Does it work?
No, not if you see " red saddle " on your cattle.
Now you have a situation where you are dealing with excess sulfur and a copper deficiency in your cattle's diet and no amount of protein will/can cure that.
