Breed Differences In Copper Requirement & Toxicity?

A few years ago Dr. Dennis Herd professor and extension beef cattle nutritionist at Texas A&M University observed, “Different breeds of animals are more susceptible for copper requirements and toxicity.  Recent research indicates Simmental and Charolais cattle require more copper in their diet than Angus,” said Dr. Herd. “Field experiences suggest that Simmental, Maine Anjou, Limousin and Charolais cattle all benefit from 1.5 times the copper intake normally defined for traditional breeds.  So you must carefully evaluate the needs of your particular breed of cattle, and genetic differences quite likely exist within all breeds.”

I wonder if this American experience is confirmed in vet practice experience in Scotland today.
