A guide to trace elements
Inadequate trace element levels in livestock result in costly issues, so achieving the correct balance of trace elements is vital for maximising performance.
Selenium, cobalt and iodine are the main trace elements required, but copper may also be deficient on some farms.
Trace element availability is influenced by soil type, types of forage, preservation of forage and also by season.
Care should be taken over the decision on whether to include copper in a formulation, because overdosing can have an adverse effect on health in some breeds of animal.
Before starting any supplementation program seek advice, as some trace elements, especially copper, are toxic if too much is present in the animal and/or the diet.
