The Animal Transport Guides are now available online. As a project funded by the European Commission, the Animal Transport Guides worked to improve the welfare of animals transported within EU countries and to third countries for the purpose of breeding, fattening and slaughter. The outputs include guides, factsheets and videos on the transport of cattle, pigs, horses, poultry and sheep. The factsheets and videos are available in multiple languages.
