The University of Nottingham (UoN) led research that resulted in the design, evaluation and national implementation of a new approach to mastitis control on British dairy farms; the `DairyCo Mastitis Control Plan'. The programme, which commenced in 2009, was implemented on farms holding 10-15% of all British dairy cows. The uptake of the scheme is continually increasing and has generated savings to the British dairy industry to the order of £5-10M per annum.
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.
Fertility of dairy cows has been in decline since the 1970's and this has threatened sustainability of the dairy industry worldwide. Research led by Nottingham University (UoN) identified key drivers of fertility and provided genetic and nutritional tools for the industry, to help combat the decline. The genetic tool was the UK Fertility Index, which is used universally by breeders for national and international bull selection. The nutritional tool, which is widely applied by international feed companies, used the concept that nutritional manipulation of insulin enhances fertility. Evidence shows that use of these tools between 2008 and 2013 has reversed the decline, and fertility is being restored. This has brought commercial benefits for breeding companies, cattle food producers and farmers and had a positive impact upon animal welfare.
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.
In the UK, one in seven dairy calves dies annually during rearing. Herd profitability is reduced further by calfhood disease and suboptimal growth rates, delaying age at first calving and reducing milk output. Professor Claire Wathes's longstanding scientific interests in dairy cattle reproduction and development have led to a broader farming industry appreciation of this issue, and to new approaches that address the economic loss and welfare issue it represents. Her results are now incorporated into professional and practical advice from DairyCo (industry levy board); Defra; farm veterinarians; commercial feed companies; opinion leaders in dairy farming; and the specialist farming media.
A novel, reliable, non-invasive and rapid method has been developed to detect excretion of Mycobacterium bovis, the causal agent of bovine tuberculosis (bTB), into the environment ("shedding") by wildlife hosts. This test has been used to establish the efficacy of the bTB vaccine on reducing environmental contamination by shedding of M. bovis in the faeces (from January 2010). It has also become an important monitoring tool used by VisaVet (European Veterinary Health Surveillance), targeting bTB in wild boar and red deer (from July 2010) to establish bTB reservoirs and take action to protect the cattle stocks. Farmers will benefit and now be able to monitor environmental contamination by M. bovis, which allows them to establish biosecurity best practice.
The method includes both a presence/absence score and a quantitative assay of infectious disease load in faecal matter in the environment. This is the first standard assay to determine environmental contamination, the main route for disease spread to cattle, and allows evaluation of the impacts of vaccination, culling and increased movement of badgers during disease- management strategies. This test also enables precise monitoring of cattle herds infected with bovine tuberculosis (bTB) as it advances from the South West to the North East of England.
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.
Impact: Economic / animal health and welfare / environment: Improved profitability and sustainability of the UK dairy industry.
Significance: The use of the Profitable Lifetime Index (£PLI) increased the profitability of the dairy sector by an estimated £634M in 2008-2013 and reduced the greenhouse gas emissions from the sector by an estimated 8.4%.
Beneficiaries: Dairy producers, breeding companies, general public/environment, dairy cattle welfare and health.

Reach: UK dairy industry. Tools developed, such as the routine recording of body condition score, and using these data in national genetic evaluations, have been widely adopted internationally, including in major dairy genetics exporting countries such as the USA, Canada, the Netherlands and New Zealand.
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.
Despite increasing surveillance, outbreaks of bovine tuberculosis (bTB) in the UK have steadily increased over the past two decades, with the disease now costing an estimated £100 million per annum in test and slaughter costs, and compensation payments.
Research by Professor Wood and Drs McKinley and Conlan has determined that successful control efforts will depend upon within-herd surveillance and also on reducing reintroduction from external sources; these results have directly altered the Department of Environment, Food and Rural Affairs' (Defra) new (July 2013) bovine TB strategy for England, which directly cites Dr Conlan's research when justifying changes in proposed regulations. On publication this research prompted questions during bovine Tuberculosis debates in both Westminster and the Scottish Parliament by Andrew George (MP, St. Ives) and Helen Eadie (MSP, Cowdenbeath) respectively. The work has also received national and specialist media coverage raising public awareness and understanding of bTB control in cattle.
