Hundreds of millions of laying hens in the European Community are now kept in enriched cages with significantly more space than conventional battery cages and with specific provision for nesting, scratching and perching. Research undertaken at Bristol University provided much of the evidence base for the full implementation of the relevant European directive in January 2012; the prohibition of the conventional battery cage and the introduction of a superior, scientifically researched alternative. This has had a dramatic impact on husbandry standards and the welfare of laying hens. With Bristol's involvement, similar progress has also been made in countries beyond Europe.
Research carried out by Professor Donald Broom at the Centre for Animal Welfare and Anthrozoology at the University of Cambridge has had a significant impact on the policy and practice surrounding farm animal welfare in the UK and beyond. Work on sow housing, calf housing, laying-hen housing, farm animal transport and other scientific work on animal welfare has led to legislation, binding codes of practice and changes in animal production and management methods in the United Kingdom and other European Union countries and many other countries around the world. In the EU, each year this affects 16 million sows, 6.5 million calves, 320 million hens and 6 billion animals that are being transported.
Impact: Policy / animal welfare. Policy implementation changed and bird welfare improved.
Significance: Our research informed welfare guidelines impacting upon housing of around 200 million laying birds in the EU. Our work has been adopted in EC regulations, and they are pushing all EU member states to ensure all their producers install aerial perches over slatted surfaces.
Beneficiaries: Laying birds, welfare organisations, egg producers, and the general public.

Reach: Guidelines have been adopted in EU legislation.
Impact: Policy, Animal Health and Welfare: Improved sow and piglet welfare and recommendations and codes of practice for farrowing and lactation systems that better meet sow and piglet needs.
Significance: Farrowing crates restrict sow movements interfering with natural sow behaviour and increasing psychological distress. Used predominantly to protect piglets, SRUC research demonstrated that piglet survival improved in loose-housed environments, undermining crate use.
Beneficiaries: Farmers, sows and piglets, the general public
Attribution: Drs Baxter and Jarvis, Professors Lawrence and Roehe (SRUC). Research collaboration was with Prof Sandra Edwards, University of Newcastle.
Reach: International legislative bans on farrowing crates; voluntary industry uptake of non-crate systems; EU recommendations/legislation on housing at farrowing, guidelines for keeping pigs (e.g. RSPCA Freedom Food).
Professor Marian Dawkins' research at the University of Oxford has established rigorous metrics of welfare for commercially-reared chickens and ducks, that have had a major impact on policy and practice. Her findings in relation to stocking densities for broiler chickens influenced the 2007 EU Broiler Directive; this was adopted by the UK in 2010, and has had a major impact on the industry. For ducks, research examined the provision of water, for which there were contradictory indications with respect to welfare and bacterial infections, and identified solutions for both. Since 2010 this has been incorporated into duck welfare programmes in which both Defra and industry participate.
Key findings of two University of Glasgow research programmes have transformed the UK egglaying industry, driving substantial improvements in productivity and bird welfare. First, two of the largest international poultry-breeding companies adopted an innovative new tool for assessing eggshell quality that was validated by University of Glasgow researchers. This tool has improved eggshell quality through selective breeding, with increased numbers of undamaged saleable eggs (saving approximately £10 million annually in the UK alone), as well as enhancing the hatchability of breeding stock eggs. Second, University of Glasgow research on the long-term health and welfare implications of infrared beak trimming influenced UK policy debate, preventing a ban on beak trimming (due to be enacted in 2011) that would have exposed 35 million laying hens to potential pecking injury or death, as well as costing the industry an estimated £4.82-£12.3 million annually.
Thousands of animals are housed in captive conditions worldwide, often to the detriment of their mental well-being. Scientists at Queen's Animal Behaviour Centre have spent the last 20 years developing new ways of improving the psychological welfare of animals housed in captivity. Their research has shown that classical music and scents such as lavender in dog shelters calms the animals, and that shielding zoo-housed gorillas from visitors with camouflage netting over the viewing windows, prevents great apes from becoming agitated. The impact of this research extends to guidelines and regulations set by the American Veterinary Medical Association, the UK's Department for Environment, Food and Rural Affairs, the British and Irish Association of Zoos and Aquariums and the Australian Government's National Health and Medical Research Council. Commercial impact includes CDs of music composed specifically for dogs, now widely available to buy on the open market, and being utilised in 1700+ rescue shelters and by over 150,000 pet owners around the globe.
Dairy-cow herds in the UK and overseas, together with the dairy farming industry, are benefiting from strategic animal-husbandry changes and lameness-control programmes underpinned by research undertaken at the University of Bristol since 1997. The dissemination by the UK Dairy Levy Board of national Standardised Lameness Scores (the DairyCo Mobility Scoring system, launched in 2008) and of Husbandry Advisory Tools (the DairyCo Healthy Feet Programme, launched in 2011) was a direct result of Bristol's work. It has led to the widespread adoption of lameness scoring as a farm-management tool, the inclusion of lameness assessment within certification schemes and a nationwide network of trained `mobility mentors'. Where implemented, this advisory support has resulted in a significant drop in lameness prevalence, thereby improving welfare and reducing the economic losses associated with treating and culling lame cows. Successful engagement with industry groups throughout the research process has ensured that scientific outputs have been rapidly implemented within the farming community. This approach has been adopted internationally with the scoring system being used by Europe's largest dairy company and a modified version is also being promoted by the New Zealand dairy industry.
