4000 farms in Wales have been screened in Bovine Viral Diarrhoea project

A collaborative programme called Gwaredu BVD involving the Royal Veterinary College ( RVC ) and Coleg Sir Gâr ’ s Agriculture Research Centre , has tested over 4,000 farms for Bovine Viral Diarrhoea ( BVD ) over the past six months .

O f those tested , 27 % have evidence of the BVD infection and some 50 have started persistent infected ( PI ) animal hunts on their farms . Gwaredu BVD is currently screening approximately 50 submissions a day in their efforts to eradicate BVD .

The ‘ Animal Health & Welfare Wales – Eradicating Bovine Viral Diarrhoea in Wales ’ project is funded by a £ 10 million award from the Welsh Government ’ s Rural Development Programme . This voluntary project , which was launched in July 2017 , has been working closely with farmers to identify herds infected with BVD . The project is managed through a partnership between The RVC and Coleg Sir Gâr ’ s Agriculture Research Centre .
BVD is a viral and immunosuppressive disease maintained by a small population of animals that become persistently infected in gestation and are a risk to the health of the rest of the herd . This affects animal welfare and can lead to pneumonia , scour , infertility and reproductive disorders .
The RVC are strongly encouraging farms that have not taken part in the screening must get involved with the programme . Testing is carried as part of the annual TB test which farms undertake and only requires 5 animals ( between the ages of 9 and 18 months ) to be blood sampled . These samples are then tested for BVD antibodies , if BVD antibodies are present on the farm , then finding and removing PI animals becomes a priority .
Dr Neil Paton , Lecturer in Farm Animal Health and Production at the RVC , said :
“ This is a hugely important initiative for Wales and we are delighted to see that the farming community has taken the opportunity to get rid of the disease on farms . Getting rid of BVD will improve the health and welfare of the Welsh cattle herd by making it more robust and productive . If farmers have not already engaged with the programme I would highly encourage them to take advantage of the free screening being offered through their vets .”

The UK is leading the charge in the fight against Bovine TB

The Agriculture and Horticulture Development Board ( AHDB ) has announced that they will be partnering with Scotland ’ s Rural College ( SRUC ) to embark on two new projects which will take the agricultural industry one step closer to eradicating Bovine TB ( bTB ).

U sing recent AHDB research which identified significant genetic variations between resistant and non-resistant dairy cattle , AHDB and SRUC intend to develop a national database of genetic evaluations and a new state-of-the-art genomic prediction tool . This will enable farmers to identify natural resistance traits and make informed decisions about which cattle they choose to breed , depending on their resistance to Bovine TB .

Combatting Bovine TB is a national priority , manifested by the £ 100 million spent annually on disease surveillance , monitoring and nongenetic control . If accuracies of genomic predictions were improved , genetic improvement could contribute to a long term reduction of this figure by reducing both infected and infectious animals on farm .
Michael Gove , the Secretary of State for the Environment , Food and Rural Affairs , reiterated the importance of eradication when he announced a review of the 25 year Bovine TB Strategy four years after it was first published .
The first of the two projects will be in partnership with the Centre for Innovation Excellence in Livestock ( CIEL ) and will focus specifically on dairy cattle . Innovate UK have granted AHDB and CIEL £ 360,000 of funding , which will enable them to buy the genotyping

“ The additional funding provided by Innovate UK will allow a far greater number of cattle to be included in the database , ensuring greater accuracy when the improved genomic prediction tool is put into practice ” says Marco Winters , Head of Animal Genetics for AHDB Dairy . He added , “ This project has gamechanging potential for the dairy industry and is a further demonstration of how the industry is actively using genetics , as part of wider industry initiatives , toward a sustainable livestock sector .”
The second project , which is being cofunded with the Department for Environment , Food and Rural Affairs ( DEFRA ), will build on AHDB ’ s initial research on dairy genetic evaluations but instead focus specifically on beef cattle . This is a slightly more complicated project due to the number of different beef cattle breeds in comparison to dairy cattle , but could reap huge savings for livestock breeders .
Farming Minister , George Eustice MP , commented : " Bovine TB is a slow moving , insidious disease which presents many challenges . That is why we are taking strong action to deliver our 25-year strategy to eradicate the disease through tighter cattle measures , improved biosecurity and badger control in areas where the disease is rife .” He added , “ Reducing the risk of disease entering a farm is crucial to end the devastation of bovine TB and that is why we have chosen to support this project which has the potential to lead to reductions in its incidence .”
Both projects are being undertaken by Scotlands Rural College ( SRUC ) and new TB Advantage evaluations will be calculated by EGENES . Professor Mike Coffey from SRUC said “ This is a major development in the battle against TB . It will increase data available for evaluations and create a new rich dataset for further research , leading to a reduction in cow to cow transmission of TB ”
AHDB were keen to point out that despite the potential of these projects , current disease control measures must continue to be adhered to as part of the UK ’ s bTB eradication strategy .
The first of the two projects , focused specifically on dairy cattle , is scheduled to commence later this year . The beef cattle project co-funded by DEFRA is already underway .
In 2015 , AHDB collaborated with , among others , the NFU , the Animal and Plant Health Agency and DEFRA to launch the ‘ TB Hub ’, offering information and advice to farmers dealing with Bovine TB issues . And , in 2016 , ‘ TB Advantage ’ was launched , a new genetic index of 650,000 animal records which helps identify resistant blood lines .
