I sent in a liver biopsy for copper testing to MSU and just got my results back. Questions are...1) Copper lever was 4 ug/g. Saanendoah "normal" level is 25-150 ppm. "Normal" levels on the MSU lab results are 60-300 ug/g. How do I compare ug/g and ppm? Also I just bolused all my goats middle of September...and this doe is still low? How can I correct this...bolus more at a time, more often, or do nothing? They have a good mineral available. 2) This was a trace mineral panel and they also tested for Iron, Zinc, Selenium, Cobalt, Molybdenum, and Manganese. Iron was extremely high 3323 ug/g and normal is 250-600 ug/g. Cobalt, Molybdenum, and Manganese are all low as well. Do I do anything with any of these? My vet looked at me like I was cuckoo asking for this test....and literally I got the lab report in the mail with no explanation from her. There is an interpretation from the MSU vet basically saying levels are adequate (??) and there is no reason to expect clinical response to increased dietary intake of these minerals. Anyone know of a good source of information on this? I am totally confused.
