  1. WORK PROGRAMME 2005-2006 FOR 5TH PRIORITY ON THE 6FP Area 6: Safer and environmental friendly methods and technologies and healthier food stuffs. Topic 6.8.: Improved rabbit production (STREP) “The objective is to ensure safer and higher quality supply of meat, by improving rabbit health and welfare through research on new rabbit production systems. More welfare-friendly productionsystems, such as colony-type housing and other sustainable systems, will be used and research will address the improvementof the quality and safety of rabbit meat by, for example, reducing the need for antibiotic treatment of epizootic rabbit enterocolitis. Results will focus on practical guidelines to help ensure the production of a high quality product throughout the EU, bearing in mind the relevance of the sector in the new member states”

  2. ALTERNATIVE RABBIT PRODUCTION SYSTEMS New healthy and welfare-friendly systems to improve safety and quality of rabbit meat Over the last few decades, European’s citizens has became increasingly concerned about meat safety and quality, with growing demand for meat from animals reared under very high welfare standards. Rabbit meat production is characterized by high production losses mainly due to digestive diseases (as epizootic rabbit enteropathy -ERE), and new breeding systems with a better disease control will improve the meat acceptability by consumers (reducing the need of antibiotic treatment), the competitiveness and sustainability of this production, as well the animal welfare. ALTERA will integrate main European rabbit research groups with the aim of develop new alternative rabbit production systems, that take into account consumer demands for high standards of animal health and welfare, reducing the input (antibiotics, hormones…), and improving meat quality and safety, as breeding profitability. New knowledge will be initially generated on alternatives to the antimicrobials for disease prevention (potential probiotics and prebiotics), on digestive physiopathology (ERE aetiology and digestive health), and on healthy welfare-friendly feeding and management systems, considering their effect on meat quality. From the new knowledge developed, alternative breeding systems will be proposed after their assessment, considering the amelioration on animal health and welfare, the improvement of rabbit meat quality and safety and their effect on the competitiveness of the sector. Guidelines for healthy and welfare-friendly rabbit meat production will be implemented to be applied for policy proposes to ensure the quality and the safety of rabbit meat. A variety of different tools will be designed to reach a suitable diffusion of the main results and milestones, especially addressed for consumer information and with the implication of main stakeholders. The core of the research network is already organized throughout a COST Action (nº848) and is able to conduct this STREP.
