Trace Minerals for California Beef Cattle
University of California, Cooperative Extension
Monterey County Mineral Data
Selenium
Samples (66) submitted to the California Veterinary Diagnostic Lab (CVDL) suggest Se is adequate. Additional samples are needed to add confidence to that assessment.
Copper
Class 3 serum and liver sample values indicate marginal Cu levels. This limited data strongly suggests the need for further testing.
Zinc
Zinc appears adequate based on Class 3 data from the CVDL.
Phosphorus
