Case Awards 2016

On 29th November, journalists from different European countries attended the BVDZero Award 2016 event held in Frankfurt. The purpose of this event was to provide a global perspective of the disease. Topics & presenters included:

  • Prevalence of Type 2 in Main European Countries, Prof Volker Moennig & Lucy Metcalfe
  • Bovela New Study on Dynamic of Immunity, Jim Roth
  • Presentations by BVDZero Award Top 3 Winnings Cases

The BVDZero Award is a recognition of cases for their exemplary detection and prevention of the disease, sponsored by Boehringer Ingelheim. Out of 45 cases that submitted from 7 countries, and carefully reviewed by the Award Committee, the following top 3 cases were rewarded on the event day.

The BVDZero Award 2016 reflected all the effort we have put into this disease, and has become an event in celebration of the steps we are taking towards a complete eradication of the disease.

Case Winners

  • Igor Ajuriaguera

  • Angela Damaso

    The Royal Veterinary College, Department of Production and Population Health, London (UK)

    Angela's case highlights risk factors in eradication of BVD such as challenges around biosecurity, slow removal of persistently infected (PI) animals and number of naive animals due to lack of vaccination.

  • BVD Control at Watergate Farm, North Yorkshire

    Katherine Lumb

    Watergate Farm, near Harrogate is a great example of a farm that has worked hard to eradicate BVD from their herd and are now seeing and feeling the benefits of being BVD free. The Baul family are milking a closed herd of just short of 200 pedigree Holsteins calving all year round and averaging just over 9,000 litres milk sold/cow/year. Over the last year calving interval has been as low as 402 days all cows are served by AI to mainly black and white sexed semen.

  • The Case of the Cow Leandra and Her Daughter Jamaicana

    Igor Ajuriaguerra

    The case starts with a call from a dairy farmer requesting a reproductive control service, specified on the day of the visit. We arrived at a farm with 80 adult cows, animals that
    had given birth at least once, 16 heifers under one year old and 22 heifers over one year but under 32 months. The farmer hired us to perform a reproductive control on the herd. We started by taking data, case history... It seemed that the number of young animals was small for the number of adult cows.

  • The consequences of pitfalls in BVDV vaccination

    Iris Kolkman

    This case report will discuss the pitfalls of BVDV control management on a Dutch dairy farm where BVDV re-entered the farm after several years of being “BVDV free” and vaccination.

  • Are beef cows more prone to the infection? Possible bias in BVD fetal infection capacity due to bovine breed

    Margarita García Liñeira

    We observed 50% of PI births in the case of the Rubia Gallega breed, whereas this percentage was 20% in the Holstein herd. Is it possible that BREED influences the likelihood of breeding a PI fetus?”

  • Impressive PI production capacity of BVD virus: more than 20% of PIs in an outbreak in a herd with 170 dairy cows in milk

    Margarita García Liñeira

    “I have a lot of doubts about what happened on this farm: a BVD clinical picture that I have never seen in my vast professional experience with BVD, in which PI
    outbreak occurs usually in a short period of time and just few PI animals are detected.”

  • Buying in a pregnant heifer resulted in a PI born in a beef herd

    Ali Haggerty

    A beef herd which had previously been considered free of BVD was found to have a positive young stock check test in 2012.

  • Identification and elimination of PI animals is essential in addition to vaccination

    Judith Badelon

    Following the detection of circulating BVD virus, the farmer vaccinated the animals but did not detect and cull PI animals until much later. His losses were estimated at €28K.

  • The financial costs of a BVD dairy herd

    Angela Damaso

    Farmers must be encouraged to start and finish a committed BVD eradication program to prevent high economic losses associated with the disease. Vets should be encouraged to carry out risk management analyses and engage in business analyses to demonstrate and discuss the benefits and the costs involved in disease interventions in each specific farm, including vaccination programs.

  • Young stock losses lead to BVD been identified in a dairy herd

    Timothy Ferry

    Between August 2015 and beginning January 2016 a 240 Holstein cow dairy herd had seen treatment and mortality rates increased in the group housed pre-weaned calves. Bovine respiratory disease (BRD) and neonatal diarrhea treatment rates were estimated to have increased from 5% to 50% and from 10% to 20% respectively. From farm records pre weaning mortally from May to July 2015 was 3% and 8% in November to December 2015. No increase in abortions or stillbirths was reported.

  • A First-calf Heifer at 4 Years Old – And It Was A PI!

    Sophie Cercelet

    ELISA tests detected BVD virus in a herd of Holsteins and Charolais cattle. The presence of a PI animal was confirmed in a four-year-old primipara.

  • When BVD is on farm ‘every problem under the sun’ has a bigger impact

    Treenie Bowser

    This case shows the importance of BVD as an underlying disease which must be eradicated from a farm to ensure that all other disease control protocols also have a successful outcome.

  • Herd BVD outbreak persisted during the years, until definitive control with a new vaccination plan in 2016

    Sofía Vázquez

    Dairy farm with 105 milking cows in Lugo, Galicia, Spain. It was a BVD-negative farm, aware of biosecurity, applying BVD-Ag-analysis to all bought animals. Good managed farm, with genetically high value cows, producing and selling embryos.

  • Chronic testicular infection during a BVD outbreak in a suckler herd

    Joan Pineda Bosh

    The suspected source of introducing the outbreak was through colostrum of an afterwards BVD-positive confirmed cow from another herd. But this was not confirmed.

  • Effects of BVD? Congenital cataracts in BVD seropositive twin calves

    Martin Steffl

    In this case we found CNS symptoms in twin Holstein calves exhibiting congenital cataracts. The tests performed did not reveal the aetiology of the pathological findings but were strongly indicative of a prior BVD infection of the mother cow. After other causes were ruled out, “congenital cataracts caused by BVDV” is regarded as a strong possibility.

  • Culling PI calves is essential as they are always a risk

    Joris Somers

    A block calving dairy herd from south Co. Carlow, Ireland referred two calves to the University Veterinary Hospital with neurological signs and a history of smaller than normal calves.

  • 80% morbidity from BVD virus causes neonatal diarrhea

    Dr. Jean-Philippe Gartioux

    “A battery of tests performed during an outbreak of neonatal diarrhea with high mortality did not detect BVD virus. Yet two PI animals were identified three months later. Identification of PI animals and vaccination led to a reduction in diarrhea cases and shorter calving intervals.”

  • PI Animal, A Sign That Calls for Testing and Vaccination of Entire Herd

    Sergio Ruiz Cordero

    “Given the farm’s recent history, I suspected it could be a new case of mucosal disease in a PI animal, which is why we tested all animals older than 3 months on the farm for BVD antibodies, and those that were negative we then tested for BVD antigen.”
