Trace Minerals for California Beef Cattle
University of California, Cooperative Extension
Sutter County Mineral Data
Selenium
Samples from 7 herds (64 head) had an average whole blood selenium value of 0.039 ppm, which is barely deficient (less than 0.04 ppm). Usually cattle at these levels will respond to supplemental selenium. It is likely that individual cattle and herds will vary. Thus, individual herd sampling is recommended.
Copper
Samples from 7 herds and 35 head had an average serum copper value of 0.69 ppm, which is adequate (0.7 ppm or more). Usually cattle at these levels will not respond to supplemental copper. Due to the small number of samples, individual herd sampling is recommended.
Zinc
Insufficient data are available for conclusions.
Phosphorus
