Can sheep alleviate pain through free choice of medicated feed?

Abstract

The focus of this thesis was to look at alternative pain-relief options for sheep with the possibility of an easy application method by providing analgesics in feed. Furthermore, if sheep can be taught to self-select and self-administer feed containing analgesics, it can provide insight into animal pain states. In order to understand why medicating livestock for pain is important, Chapter 1 provides an introduction into pain in livestock and its impact on their welfare.
