Rumen fluid was sampled in rumen fistulated cows assigned to a 5\u00d75\u00a0Latin square study design. The pH values of samples taken by stomach tubes and via fistulas were measured; the results were compared with indwelling sensor measurements. The practicability of the stomach tubes for regular use was tested in the field. Rumen fluid samples were obtained rapidly. Volumes for transfaunation could be obtained. The pH\u2010values of samples taken with the four out of the five tubes (Dirksen, Geishauser, tube 4 and a simple water hose used with a gag) did not show significant differences to samples taken via rumen fistulas. Mean differences ranged between \u22120.02 and +0.09. Samples taken with tube 4 and the water hose showed also no significant differences to pH\u2010sensor measurements. This study demonstrates that stomach tubes are suitable for rumen fluid sampling. Tube 4 seems to be the best probe for work in the field. It was well tolerated by the animals, saliva contamination is negligible. We, therefore, conclude that the evaluation of rumen acid base status in the field is possible.<\/jats:p>","DOI":"10.1136\/vr.102399","type":"journal-article","created":{"date-parts":[[2014,10,21]],"date-time":"2014-10-21T02:31:53Z","timestamp":1413858713000},"page":"50-50","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":23,"title":["Randomised prospective study compares efficacy of five different stomach tubes for rumen fluid sampling in dairy cows"],"prefix":"10.1002","volume":"176","author":[{"given":"S.","family":"Steiner","sequence":"first","affiliation":[{"name":"Department of Farm Animals and Veterinary Public Health University Clinic for Ruminants, University of Veterinary Medicine (Vetmeduni) Vienna Veterin\u00e4rplatz 1 Vienna 1210 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Neidl","sequence":"additional","affiliation":[{"name":"Department of Farm Animals and Veterinary Public Health University Clinic for Ruminants, University of Veterinary Medicine (Vetmeduni) Vienna Veterin\u00e4rplatz 1 Vienna 1210 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Linhart","sequence":"additional","affiliation":[{"name":"Department of Farm Animals and Veterinary Public Health University Clinic for Ruminants, University of Veterinary Medicine (Vetmeduni) Vienna Veterin\u00e4rplatz 1 Vienna 1210 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Tichy","sequence":"additional","affiliation":[{"name":"Department for Biomedical Science Platform Biostatistics, University of Veterinary Medicine (Vetmeduni) Vienna Veterin\u00e4rplatz 1 Vienna 1210 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Gasteiner","sequence":"additional","affiliation":[{"name":"Agricultural Research and Education Centre, Raumberg\u2010Gumpenstein Raumberg 38 Irdning 8952 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Gallob","sequence":"additional","affiliation":[{"name":"Agricultural Research and Education Centre, Raumberg\u2010Gumpenstein Raumberg 38 Irdning 8952 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W.","family":"Baumgartner","sequence":"additional","affiliation":[{"name":"Department of Farm Animals and Veterinary Public Health University Clinic for Ruminants, University of Veterinary Medicine (Vetmeduni) Vienna Veterin\u00e4rplatz 1 Vienna 1210 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Wittek","sequence":"additional","affiliation":[{"name":"Department of Farm Animals and Veterinary Public Health University Clinic for Ruminants, University of Veterinary Medicine (Vetmeduni) Vienna Veterin\u00e4rplatz 1 Vienna 1210 Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,1,10]]},"reference":[{"key":"e_1_2_5_2_1","first-page":"367","article-title":"A dirigible stomach tube for taking rumen fluid in cattle","volume":"8","author":"DIRKSEN G.","year":"1975","journal-title":"Tier\u00e4rztl Umschau"},{"key":"e_1_2_5_3_1","doi-asserted-by":"crossref","first-page":"108","DOI":"10.21423\/bovine-vol0no22p108-116","article-title":"Acquisition and analysis of bovine rumen fluid","volume":"22","author":"DIRKSEN G.","year":"1987","journal-title":"Bovine Practitioner"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(04)73142-2"},{"key":"e_1_2_5_5_1","first-page":"677","volume-title":"A Textbook of Veterinary Anatomy","author":"DYCE K.
