Trace Minerals for California Beef Cattle
University of California, Cooperative Extension
Lake County Mineral Data
Selenium
A limited number of class 3 samples suggest Se status is marginal. The number of samples is too low to be confident of any assessment. Additional sampling is needed to clearly identify Se status.
Copper
Limited samples suggest Cu status is probably adequate. Additional testing is needed.
Zinc
A very few samples show high Zn levels. These could be from one herd that is providing excess supplementation. Further testing is needed.
