Indicators of negative welfare, behavioural indicators of positive welfare and environmental outcomes were assessed.\r\n\r\nClear differences between conditions were detected. Birds in Condition 4 experienced the poorest health (highest mortality and post-mortem inspection rejections, poorest walking ability, most hock burn and pododermatitis) and litter quality.\r\n\r\nThese birds also displayed lower levels of behaviours indicative of positive welfare (enrichment bale occupation, qualitative &#8216;happy\/active&#8217; scores, play, ground-scratching) than birds in Conditions 1-3.\r\n\r\nThese findings provide farm-based evidence that significant welfare improvement can be achieved by utilising slow-growing breeds. There are suggested welfare benefits of a slightly lower planned maximum stocking density for Breed B and further health benefits of the slowest-growing breed, although these interventions do not offer the same magnitude of welfare improvement as moving away from fast-growing broilers. \r\n\r\nThe study is from FAI Farms, Northfield Farm, Wytham, UK; Division of Food Animal Science, Bristol Veterinary School, University of Bristol, Langford, UK; Department of Animal and Aquacultural Sciences, and Faculty of Biosciences, Norwegian University of Life Sciences, \u00c5s, Norway.\r\n\r\nAnn C Rayner , Ruth C Newberry , Judit Vas, Siobhan Mullan. <em>Sci Rep<\/em> 2020; 10(1):15151. <a href=\"http:\/\/doi.org\/10.1038\/s41598-020-72198-x\">DOI link<\/a>.","protected":false},"excerpt":{"rendered":"<p>Broiler chicken welfare is under increasing scrutiny due to welfare concerns regarding growth rate and stocking density.
