Trace elements in sheep: history taking

Abstract

Trace elements impact the health and productivity of UK sheep flocks when supply is not optimal. The consequences of suboptimal supply can result in various clinical presentations. However, in some instances, unproven trace element deficiencies and their correction have been lauded as a panacea for all manner of conditions. Therefore, it is important to gather sufficient evidence to support a presumptive diagnosis and justify laboratory test expenditure. These tests are often not as diagnostically definitive as we would like and should be interpreted in conjunction with background evidence. In addition, a better understanding of the factors contributing to each particular presentation of deficiency may improve targeted nutritional management.
