Bulk milk samples were tested for antibodies to bovine viral diarrhoea virus (BVDV), bovine herpesvirus type 1 (BHV\u20101) and\n                    <jats:italic>Leptospira<\/jats:italic>\n                    Hardjo, and samples were also tested for the presence of BVDV antigen by PCR. A questionnaire was used to determine whether the herd was open or closed, what the vaccination status was, and to obtain general farm information such as the herd size and average milk yield. Vaccination against BVD, infectious bovine rhinotracheitis and leptospirosis was practised on 37, 12 and 35 per cent of the farms, respectively. The presence of bulk milk antibodies on farms that did not use vaccination was 75 per cent for BVDV, 54 per cent for BHV\u20102 and 76 per cent for L Hardjo. Open herds had 10 times the odds (95 per cent confidence interval [CI] 1.7 to 59.4)of having bulk milk antibodies for BVDV and 16.7 times the odds (95 per cent CI 2.0 to 49.7) of having bulk milk antibodies to BHV\u20101 compared with closed herds. A farm with bulk milk antibodies to one disease had significantly higher odds of having bulk milk antibodies to a second disease (P&lt;0.05).\n                  <\/jats:p>","DOI":"10.1136\/vr.c5256","type":"journal-article","created":{"date-parts":[[2010,10,22]],"date-time":"2010-10-22T06:40:25Z","timestamp":1287729625000},"page":"644-647","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":16,"title":["Indications of a relationship between buying\u2010in policy and infectious diseases on dairy farms in Wales"],"prefix":"10.1002","volume":"167","author":[{"given":"H.","family":"Bishop","sequence":"first","affiliation":[{"name":"Welsh Regional Veterinary Centre Royal Veterinary College Gelli Aur College Farm Carmarthen SA32 8NJ"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Erkelens","sequence":"additional","affiliation":[{"name":"Welsh Regional Veterinary Centre Royal Veterinary College Gelli Aur College Farm Carmarthen SA32 8NJ"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Van Winden","sequence":"additional","affiliation":[{"name":"Welsh Regional Veterinary Centre Royal Veterinary College Gelli Aur College Farm Carmarthen SA32 8NJ"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,10,23]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-0720(15)30471-0"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(03)00830-2"},{"key":"e_1_2_5_4_1","unstructured":"Defra(2008)The Cattle Book 2008: descriptive statistics of cattle numbers in Great Britain on 1st June 2008.www.defra.gov.uk\/foodfarm\/farmanimal\/diseases\/vetsurveillance\/documents\/cattlebook\u20102008.pdf.
