Trace Mineral Nutrition of Sheep

Trace mineral nutrition of sheep often focuses on their greater susceptibility to copper toxicosis due to a lesser biliary excretion ability compared with other ruminants. Our understanding of sheep trace mineral requirements has improved for most elements allowing for a factorial approach to determining daily requirement instead of a dietary concentration. Forage trace mineral content is influenced by many factors making issues of trace mineral supplementation geographic-dependent. Oral delivery of trace elements is a preferred supplementation method, and this can be achieved through free choice trace mineralized salt or direct dietary incorporation.
