Diagnosing SARA is challenging due to the need to evaluate multiple parameters, such as milk fat\/protein ratio, ruminal lactate, and hemogram, instead of relying on a single definitive symptom or diagnostic method. This study aimed to evaluate the effectiveness of computerized rumen colorimetry in detecting SARA in beef cattle. Over one year, 75 cattle aged 8\u201310 months from five farms were periodically monitored for rumen pH prior to slaughter. Samples of rumen wall and rumen content were obtained at slaughter for analysis. The study found a positive correlation coefficient between rumen pH and color components, particularly for Red (0.853) and color lightness (L) (0.862). The darkening of the rumen epithelium\u2019s color was attributed to the effect of rumen pH on the keratinized layer of the epithelium. Furthermore, an increase in the thickness of ruminal epithelium layers, particularly non-keratinized and total epithelium, was observed in animals with a history of SARA. It is possible that the lower rumen pH increases the rate of replacement of the keratinized epithelium, and the non-keratinized epithelium overgrows to compensate for the need to of produce keratinized layers. In conclusion, computerized rumen colorimetry shows promise as a reliable method for managing SARA in bovine farms by monitoring the condition in the slaughterhouse. Further research is needed to evaluate its effectiveness in detecting SARA in live animals.<\/jats:p>","DOI":"10.1007\/s11259-023-10231-w","type":"journal-article","created":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T03:33:19Z","timestamp":1696822399000},"page":"475-484","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Can computerized rumen mucosal colorimetry serve as an effective field test for managing subacute ruminal acidosis in feedlot cattle?"],"prefix":"10.1007","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5567-1328","authenticated-orcid":false,"given":"Nikolaos","family":"Voulgarakis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9229-3151","authenticated-orcid":false,"given":"Dimitrios","family":"Gougoulis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1539-4124","authenticated-orcid":false,"given":"Dimitra","family":"Psalla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3434-0877","authenticated-orcid":false,"given":"Georgios","family":"Papakonstantinou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8443-8645","authenticated-orcid":false,"given":"Panagiotis-Dimitrios","family":"Katsoulos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2432-183X","authenticated-orcid":false,"given":"Konstantinos","family":"Katsoulis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8191-2161","authenticated-orcid":false,"given":"Mariana","family":"Angelidou-Tsifida","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8723-2629","authenticated-orcid":false,"given":"Labrini","family":"Athanasiou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4955-0460","authenticated-orcid":false,"given":"Vasilleios","family":"Papatsiros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2692-8910","authenticated-orcid":false,"given":"Georgios","family":"Christodoulopoulos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,10,9]]},"reference":[{"key":"10231_CR1","doi-asserted-by":"publisher","first-page":"666","DOI":"10.3168\/jds.2016-10871","volume":"100","author":"JA Abaker","year":"2017","unstructured":"Abaker JA, Xu TL, Jin D, Chang GJ, Zhang K, Shen XZ (2017) Lipopolysaccharide derived from the digestive tract provokes oxidative stress in the liver of dairy cows fed a high-grain diet.
