With all due respect, WB, I don't agree that copper always needs to be chelated. I will agree that in some instances, perhaps, it does.WB wrote:The copper needs to be chelated. The oxide and sulfur forms are just not absorbable enough. What is the water source?Our breedup is always less for the cows on artesian water.
I have been a mineral dealer for 24+years and the only time I have ever sold chelated mineral was to a veterinarian doing embryo
transplants. We have a mineral formulation that has 2 sources of (non-chelated) copper and it has worked extremely well.
Granted, the mineral needs to have enough copper and zinc. The ratio of those two, copper and zinc, must be right or
it will cause other problems. FWIW.
Not saying we don't offer chelated mineral in our line-up,we do. It is just that our customers haven't seen a need for it as
they are getting great performance without it. They feel that if their herd history has proven not to need it, why pay the extra cost?
