Trace Minerals for California Beef Cattle
University of California, Cooperative Extension
San Benito County Mineral Data
Selenium
Data from one herd (10 head) showed individuals ranged from 0.069 to 0.167 ppm whole blood selenium, the average was 0.106 ppm. This is considered adequate. Additional data is needed to draw firm conclusions. Additional sampling of individual herds is recommended.
Copper
Limted samples (39) submitted to the California Veterinary Diagnostic Lab (CVDL) suggest marginal Cu levels. However, insufficient data are available for conclusions. Further testing is needed.
Zinc
Limited samples (19) submitted to the CVDL suggest adequate Zn levels, however variation was large. Insufficient data are available for conclusions. Further testing is recommended.
Phosphorus
Insufficient data are available for conclusions.
