Shandong Province plays a significant role in China's livestock industry, with an increasing importance in food of Holstein and Angus cattle. However, BLV prevalence in Holstein and Angus breeds in Shandong Province remains unclear. In particular, there are no reports of BLV prevalence of Angus cattle in field surveys worldwide. In this study, 613 samples from six large\u2010scale farms (&gt;\u20091000 heads per farm) in Binzhou and Weifang cities were screened for BLV antibodies (gp51) using an enzyme\u2010linked immunosorbent assay. The samples included 303 Angus (beef) and 310 Holstein (dairy) cattle. All Angus breeding samples from the three farms were BLV\u2010negative at both the animal\u2010 and herd\u2010level prevalences. In contrast, 62 of 310 Holstein cattle (20.0%) from three dairy farms were positive for BLV antibodies. For example, 35\/110 (31.8%), 19\/100 (19.0%), and 8\/100 (8.0%) samples from the D, E, and F farms, respectively, were BLV\u2010positive. Notably, the animal\u2010 and herd\u2010level prevalences for Holstein cattle exhibited 20% and 100% positivity, respectively. These findings offer significant insights into the BLV status of Holstein and Angus cattle in Shandong Province, China.<\/jats:p>","DOI":"10.1111\/1348-0421.70042","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T08:20:55Z","timestamp":1768897255000},"page":"175-181","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Comparison of the Prevalence of Bovine Leukemia Virus (BLV) in Holstein and Angus Cattle Breeds From Shandong Province, China"],"prefix":"10.1111","volume":"70","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-1109-9503","authenticated-orcid":false,"given":"Jingyuan","family":"Wang","sequence":"first","affiliation":[{"name":"Laboratory of Global Infectious Diseases Control Science, Graduate School of Agricultural and Life Sciences The University of Tokyo Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9835-2167","authenticated-orcid":false,"given":"Lin","family":"Dong","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9305-9353","authenticated-orcid":false,"given":"Guangjun","family":"Guo","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1450-7279","authenticated-orcid":false,"given":"Chunyang","family":"Yao","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3724-3239","authenticated-orcid":false,"given":"Changjiang","family":"Wang","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-6487-7815","authenticated-orcid":false,"given":"Fengrong","family":"Tian","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9496-8149","authenticated-orcid":false,"given":"Feng","family":"Wei","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6655-7146","authenticated-orcid":false,"given":"Jishan","family":"Liu","sequence":"additional","affiliation":[{"name":"Shandong Binzhou Animal Science and Veterinary Medicine Academy Binzhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-5768-2819","authenticated-orcid":false,"given":"Xuebo","family":"Wang","sequence":"additional","affiliation":[{"name":"Shandong Lvdu Biological Technology Co.
