This paper explains how research can contribute to an understanding of the welfare issues associated with transportation and the value of basing legislation to protect the welfare of animals on scientific evidence.However, it also indicates the limitations of existing research methodology and identifies where research can make a clear contribution to the amendment of existing legislation. The research should accurately reflect commercial practice and should focus upon the provision of readily transferable technological improvements and relevant legislation that will optimize both welfare and productivity. Research into the effects of transport on the welfare of animals involves the investigation of a multicomponent process which can potentially affect the welfare of animals in many ways. The research should identify and quantify those components of transport environments and practices which constitute a major risk to the welfare of animals and determine the optimum conditions for transportation based upon matching the conditions and procedures to the animals’ biological requirements. A range of different measurements have been made to evaluate the responses of farm animals to transportation. Physiological and biochemical variables should be selected to reflect responses or disturbances in the major homeostatic systems influenced by transport environments and practices. The value of the different measurements is strengthened by an understanding of the action and functional significance of the responses. Animal welfare legislation should be based upon sound scientific evidence relating to the animals’ physiological and behavioural requirements and their interaction with their immediate environment. Nowhere is this more important than in animal transportation.
