While it has been shown that 20-30% of farms in NZ are deficient in at least one of the three main trace elements (copper, cobalt and selenium), only a small percentage of farmers are testing regularly. There are three testing methods for trace elements:
We operate a simple, and reliable liver trace element testing service, which has been accepted by all meat companies except Alliance.
Five liver samples (or less if fewer animals are sent) are collected by AsureQuality NZ (meat inspecting service) and sent to Gribbles Laboratories, who will perform a standard set of tests, ie copper, cobalt and selenium for sheep; copper and selenium for cattle and deer.
The results are sent directly from the laboratory to your nominated veterinarian or veterinary practice, who will then interpret the results and make recommendations back to you directly.
The results are also supplied to Ravensdown and will be entered into our database in the same way that soil test results are be stored for you.
Please Note: The Alliance meatworks do not take part in our liver testing service; they will only collect liver samples if one of their own ‘OptiHealth’ submission forms is used.
