Tail docking and castration of lambs
نویسنده
چکیده
Freedom from pain and physical distress is widely accepted as being a critical part of animal welfare. However, in order to minimize suffering by the animal we must first devise a scale with which to assess the degree of pain that it is feeling. There have been several important developments in animal research in the last twelve months pertaining to pain evaluation in animals. The aim of each of these studies was to determine the most accurate and reliable ways of assessing the level of pain felt by lambs during routine castration and tail docking. It was found that a combination of indices, involving both the measurement of physiological parameters, and observation of behaviours, were most effective for reliable measurement of pain.
