Incidence rate (IR) was defined as the number of first cases of each disease divided by the number of lactations per farm. Clinical mastitis (CM) remains the most diagnosed disease of dairy cows. Across all herds, the mean IR (cases per 100 cow-lactations) was 24.4 for clinical mastitis, 14.5 for foot disorders (FD), 11.2 for metritis (ME), 8.6 for ketosis (KE), 7.4 for retained fetal membranes (RFM), 4.5 for diarrhea (DI), 3.1 for displaced abomasum (DA), 2.9 for pneumonia (PN) and 1.9 for milk fever (MF). More than 30% of cows that had first cases of CM, DA, RFM, DI, and FD did not receive antibiotics. Of those treated, more than 50% of cows diagnosed with PN, ME and CM received ceftiofur as a treatment. The IR of mastitis and most other diseases was greater in older cows (parity \u2265 3) during the first 100 days of lactation and these cows were more likely to receive antibiotic treatments (as compared to younger cows diagnosed in later lactation). Cows of first and second parities in early lactation were more likely to remain in the herd after diagnosis of disease, as compared to older cows and cows in later stages of lactation. Most older cows diagnosed with CM in later lactation were culled before completion of the lactation. These results provide baseline data for disease incidence in dairy cows on modern U.S. dairy farms and reinforce the role of mastitis as an important cause of dairy cow morbidity.<\/jats:p>","DOI":"10.3390\/pathogens11111282","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T08:15:12Z","timestamp":1667376912000},"page":"1282","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Incidence and Treatments of Bovine Mastitis and Other Diseases on 37 Dairy Farms in Wisconsin"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2138-4982","authenticated-orcid":false,"given":"Juliano L.","family":"Gon\u00e7alves","sequence":"first","affiliation":[{"name":"Department of Large Animal Clinical Sciences, College of Veterinary Medicine, Michigan State University, East Lansing, MI 48864, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana L.","family":"de Campos","sequence":"additional","affiliation":[{"name":"Department of Large Animal Clinical Sciences, College of Veterinary Medicine, Michigan State University, East Lansing, MI 48864, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4222-5406","authenticated-orcid":false,"given":"Andrew J.","family":"Steinberger","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nasia","family":"Safdar","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashley","family":"Kates","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajay","family":"Sethi","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4253-8314","authenticated-orcid":false,"given":"John","family":"Shutske","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6170-711X","authenticated-orcid":false,"given":"Garret","family":"Suen","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3962-4913","authenticated-orcid":false,"given":"Tony","family":"Goldberg","sequence":"additional","affiliation":[{"name":"Department of Bacteriology, University of Wisconsin, Madison, WI 53706, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger I.","family":"Cue","sequence":"additional","affiliation":[{"name":"Department of Animal Science, Macdonald Campus, McGill University, Montreal, QC H9X 3V9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7211-4512","authenticated-orcid":false,"given":"Pamela L.","family":"Ruegg","sequence":"additional","affiliation":[{"name":"Department of Large Animal Clinical Sciences, College of Veterinary Medicine, Michigan State University, East Lansing, MI 48864, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,1]]},"reference":[{"key":"ref_1","unstructured":"USDA (2022, October 31).
