Abstract

Mobile and semi-mobile abattoirs, in which animals can be slaughtered on the farm or near the farm, could be an alternative slaughtersystem to the conventional one. This alternative is aimed to minimize stress induced by handling and transport activities on animals prior to slaughtering, and thereby attenuate the risks for reduced meat quality. More over, minimized transport could lead to reduction of environmental degradation imposed by emissions generated from vehicles. The objective of the project was to map out possibilities and constrains associated with mobile abattoirs for cattle, sheep, swine and poultry, and to identify pertinent and steering parameters and factors which may determine the development and implement of mobile abattoirs. The project included a literature review, study visits to abattoirs for cattle and swine and a mobile abattoir for deer. Interviews with relevant individuals and organisations were also carried out. The proposals for the mobile abattoirs are based on the rules and regulations set up by 'Livsmedelsverket' concerning slaughter hygiene and the animal protection act concerning handling of slaughter animals. In common, for cattle, sheep swine and poultry slaughter, the suggested mobile abattoir comprises the following components: a component for stunning, slaughter and cooling and a separate cooling component for transportation of meat. In the semi-mobile abattoir, there will also be a component for butchering of meat. Water of good hygienic quality in sufficient amounts are needed. Slaughter waste may be decomposed after being heated to 70° C, which might be a problem in mobile abattoir. In semi-mobile, the waste could be handled easily. It is assumed that mobile and semi-mobile abattoirs could lead to a better handling of slaughter animals, which might decrease stress and give a better quality of meat. If transport of live animals could cease, as with mobile abattoirs, many factors related to stress could be eliminated. But there will always be some factors, for example, preloading handling, that can lead to stress even in mobile abattoir system. The skills and knowledge of the personal handling the animals is very important for good animal welfare. Decreased transport, as with semi-mobile abattoirs, lead to reduction of pressure on the environment.
