One hundred and sixty-one cows were fitted with a Ruminact\u00a9 HR-Tag and from these 20 also received SmaXtec\u00a9 ruminal boli approximately 5 days before calving. Drenching and control groups were established based on calving dates. Animals in the drenching group were dosed three times (Day 0\/day of calving\/, Day 1, and Day 2 after calving) using a feed additive containing calcium propionate, magnesium sulphate, yeast, potassium chloride and sodium chloride mixed in approximately 25\u2009L of lukewarm water. RT before calving and sensitivity to subacute ruminal acidosis (SARA) were considered in the final analysis. There was a significant decrease in RT in the drenched groups compared to the controls after drenching. Reticuloruminal pH was significantly higher and time below reticuloruminal pH 5.8 remained significantly lower in SARA-tolerant drenched animals on the days of the first and the second drenchings. Drenching temporarily decreased RT in both drenched groups compared to controls. The feed additive had a positive effect on reticuloruminal pH and time below reticuloruminal pH 5.8 in tolerant drenched animals.<\/jats:p>","DOI":"10.1556\/004.2023.00835","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T15:14:00Z","timestamp":1683299640000},"page":"46-53","update-policy":"https:\/\/doi.org\/10.1556\/policypage.crossmark.crossref.2","source":"Crossref","is-referenced-by-count":1,"title":["Effect of postpartum drenching on rumination time and reticuloruminal pH at a Hungarian dairy farm"],"prefix":"10.1556","volume":"71","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3414-7716","authenticated-orcid":true,"given":"Lea","family":"L\u00e9n\u00e1rt","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Food Animal Medicine Clinic, University of Veterinary Medicine, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"},{"name":"MTA\u2013SZIE Large Animal Clinical Research Group, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andr\u00e1s","family":"Horv\u00e1th","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Food Animal Medicine Clinic, University of Veterinary Medicine, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"},{"name":"MTA\u2013SZIE Large Animal Clinical Research Group, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tam\u00e1s","family":"Kis","sequence":"additional","affiliation":[{"name":"D\u00f3zsa Agricultural Ltd.-Tass, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D\u00e1vid","family":"Buj\u00e1k","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Food Animal Medicine Clinic, University of Veterinary Medicine, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"},{"name":"MTA\u2013SZIE Large Animal Clinical Research Group, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ott\u00f3","family":"Szenci","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Food Animal Medicine Clinic, University of Veterinary Medicine, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"},{"name":"MTA\u2013SZIE Large Animal Clinical Research Group, H-2225, \u00dcll\u0151, D\u00f3ra Major, Hungary"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"B1","series-title":"Bov.
