Impact: Economic, public policy and animal health and welfare: Selective breeding based upon identification of PRNP genotypes can eliminate animals that are susceptible to scrapie from the flock.
Significance: UK sheep meat exports are worth >£380million. Breeding for scrapie resistance protected the sheep industry from similar damage to that inflicted by BSE on cattle and the UK economy.
Beneficiaries: Farmers, animals, consumers
Attribution: Professor Hunter and Dr. Goldmann (Roslin Institute, now part of UoE) identified polymorphisms of the PrP (PRNP) gene linked to scrapie susceptibility and resistance in sheep.
Reach: International, programmes breeding for resistance to scrapie in sheep are now used in the UK, Europe and USA.
Impact: Economic / animal health and welfare: Established health schemes to control Bovine Viral Diarrhoea (BVD) on Scottish farms and subsequently underpinned the rationale for cost-effective control strategies that have been adopted in health schemes around the UK. The farm-level savings to the industry from future eradication are estimated by Scottish Government to be £50- £80m.
Significance: BVD is a major endemic disease of cattle in Scotland costing the dairy industry about £38M per year and an additional £11M to consumers.
Beneficiaries: Farmers, cattle, animal health authorities.
Attribution: Professors Gunn and Stott (SRUC).
Reach: The associated health schemes began in Scotland (HI Health) and now operate throughout Britain (UK CHeCS (Cattle Health Certification Standards) Health Scheme). The research underpins BVD control schemes in Ireland and other EU Member States resulting in an avoided output loss of between €500 to €4,000 per dairy farm per year.
The parasite Neospora caninum is the leading cause of abortion in cattle in the UK, resulting in around 6,000 abortions per year; and a $1.3b pa international problem. There are no effective drugs or vaccines to control neosporosis. University of Liverpool (UoL) research on the development of diagnostic tests, understanding the pathogenesis, epidemiology and transmission of N. caninum has made an important contribution to developing best practise herd health schemes, now offered by the Animal Health and Veterinary Laboratories Agency (AHVLA) and by a commercial company `myhealthyherd', to eradicate N. caninum infection from a herd. This has enabled cattle farmers to improve their businesses by reducing abortion rates and other costs associated with neosporosis.
Impact: Economics, policy, animal and human health: In 2006, SoS (a Public Private Partnership-PPP) was established involving: University of Edinburgh, a pharmaceutical company, a charity, and the Govt. of Uganda to control sleeping sickness by eliminating Trypanasome carriage in cattle. The prevalence of trypanosomiasis has been reduced by 75% and sleeping sickness cases have fallen year on year since the PPP was established and Uganda has received a cost benefit between US$125 and $400M
Beneficiaries: The Ugandan population, Ugandan Cattle population.
Significance: Sleeping sickness, which is difficult to diagnose and treat in humans, is often fatal. Ten million Ugandans are at risk from sleeping sickness. SoS established a veterinary network in Uganda producing
Attribution: Professor Welburn (University of Edinburgh, UoE) founded SoS and developed essential diagnostic techniques.
Reach: SoS provides a model for the elimination of the disease across sub Saharan Africa in an economically sustainable fashion - with over 22 million people at risk.
Research conducted at the University of Bristol between 2003 and 2012 on the ecology, epidemiology and control of parasitic flies and worms has improved animal health and welfare in the UK and is addressing a major constraint on global food production — animal disease, particularly in the context of climate change. These are some of the impacts:
Omega-3 long-chain polyunsaturated fatty acids (LC-PUFA) are essential nutrients and have many beneficial effects on human health. Fish are the major source of omega-3 LC-PUFA in the human diet, and its level was maintained in farmed fish through the use of fish oil as a major component of extruded aquafeeds. Around 10 years ago it became clear that demand for fish oil would rapidly outstrip supply, limiting expansion of aquaculture activities, if fish oil use was not reduced. The challenge this presented was that alternatives to fish oil lack omega-3 LC-PUFA. However, replacement of fish oil with more sustainable alternatives is now standard practice in the industry. Research into fish oil replacement and omega-3 metabolism in the Nutrition Group, Institute of Aquaculture has been at the forefront of the scientific research in the UK and Europe that has ensured nutritional quality of farmed fish by developing alternative feed ingredients and feeding strategies that have maintained levels of omega-3 LC-PUFA despite radical changes to feed composition driven by sustainability and food security. This work culminated with recent demonstrations that farmed salmon can be net producers of marine protein (2010) and oil (2011).
Three specific projects have addressed issues of resource utilisation and pollution related to poultry production. The novel form of silicon developed by the Poultry Research Unit (PRU) has been taken into the product portfolio of a FTSE100 company, AB Agri [Associated British Agriculture PLC] as a feed supplement to reduce poultry lameness. There are approximately 48 billion meat chickens produced globally every year but high incidence of lameness leads to economic loss and avoidable environmental pollution. In conjunction with ABAgri, PRU also produced evidence-based research resulting in a patent for recovering yeast from bioethanol production. The process is now being implemented by ABAgri to produce high-quality protein for poultry feed alongside bioethanol production to reduce the carbon footprint of both bioethanol and poultry meat production.
A University of Glasgow bovine tuberculosis (bTB) surveillance model was fundamental to new Scottish Government policy on bTB testing. Implemented on 1st January 2012, the policy change used the Glasgow model to indicate which cattle herds can be exempt from routine testing while still maintaining Scotland's Officially bTB Free status. In 2012 this translated to exemption of more than 30% of Scottish herds from routine testing, with an associated government saving of £150,000. The revised policy also provided savings to the Scottish farming industry in the region of £100,000 (2012) and limited the risks of bTB testing to farmers, veterinarians and cattle. The rapid success of the ground-breaking Scottish research-led bTB policy development has been highlighted by the Civil Service as best practice and has been presented to numerous policy audiences including the European Commission, providing the opportunity to transform industry practices and livestock surveillance policy across the UK and beyond.
Different aspects of Professor Paul Watson's research on artificial insemination and semen preservation techniques, have delivered impact in agricultural, human healthcare and ecological spheres. They have contributed to commercial breeding practices, particularly in pigs, providing substantially improved efficiencies and reliability. Research on reducing transmission of infectious agents by semen during storage in liquid nitrogen has been applied to human AI, informing and driving changes in practice to protect against contamination leading to infection. In the field of conservation, the RVC's research has made a significant contribution to international efforts directed at the survival of highly endangered species, supporting preservation of biodiversity.
The use of non-steroidal anti-inflammatory drugs (NSAIDs) for their pain-relieving properties in cattle medicine has lagged behind that of other species (e.g. companion animals) where analgesic use is now routine. University of Nottingham (UoN) research exploring the attitudes of vets and farmers to the use of NSAIDs in cattle, and subsequent marketing by Boehringer Ingelheim, a multinational pharmaceutical company, has led to a substantial increase in analgesic use. UoN research increased sales for Boehringer Ingelheim and almost doubled the UK market value of NSAIDs for use in cattle. With administration of up to 2 million additional doses per year, the research had clear benefits for animal welfare.
