Ergebnisse: Etwa ein F\u00fcnftel der Untersuchungen erfolgten allein zur Kontrolle des Stoffwechselstatus. Die weiteren Einsendungsgr\u00fcnde entsprachen den Merzungsursachen. Die FFS zeigten im Laktationsverlauf ante partum mit 56,7% die h\u00e4ufigsten Referenzwertabweichungen. Bis 8 Wochen post partum (p. p.) verringerte sich dieser Anteil auf 36\u201338% und sp\u00e4ter auf &lt; 11%. Die BHB-Referenzwertabweichungen \u00fcberschritten in der gesamten Laktation 68%. Die Harnstoffkonzentration lag in der Mittel- und Sp\u00e4tlaktation zu 40\u201350% \u00fcber dem Referenzbereich. Eine Hypokalz\u00e4mie trat in der 1. Woche p. p. zu 13,2% auf, eine Hypophosphat\u00e4mie zu 6,6%. F\u00fcr die CK wurden Referenzwertabweichungen mit einem Anteil von 60,4\u201390,9% ermittelt. Ein Selen- und Kupfermangel bestand zu ca. 15%. F\u00e4rsen wiesen mit 21,3% h\u00e4ufiger als die K\u00fche eine Kupferunterversorgung auf. Ein \u03b2-Carotin-Mangel ergab sich ante partum zu 50% und post partum zu 47,1\u201377,8%. Nachteilige Referenzwertabweichungen nahmen von 2006 bis 2011 bei FFS, Harnstoff, \u03b2-Carotin und Selen zu, korrelierend mit den Milchpreissenkungen 2009 und 2010. Referenzwertabweichungen von BHB, CK, Cholesterol, Kalzium und anorganischem Phosphat blieben auf einem Niveau. In 80% der Betriebe verbesserte sich der Stoffwechselstatus im Kontrollzeitraum. Schlussfolgerung: Auch in kleineren Betrieben decken Stoffwechselscreenings peripartal fr\u00fchzeitig Ursachen f\u00fcr die h\u00e4ufigsten Merzungsgr\u00fcnde auf und bieten Optionen f\u00fcr korrigierende Ma\u00dfnahmen.<\/jats:p>","DOI":"10.15653\/tpg-151032","type":"journal-article","created":{"date-parts":[[2016,3,21]],"date-time":"2016-03-21T15:17:16Z","timestamp":1458573436000},"page":"83-91","source":"Crossref","is-referenced-by-count":0,"title":["Stoffwechselmonitoring in kleinen und mittelgro\u00dfen Milchrindbetrieben im Emsland"],"prefix":"10.15653","volume":"44","author":[{"given":"J.","family":"Bothmann","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Magnus","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.","family":"Hasseler","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Kossen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"F\u00fcrll","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,12,21]]},"reference":[{"issue":"G","key":"10.15653\/TPG-151032-1","first-page":"88","volume":"41","author":"Ackermann","year":"2013","journal-title":"Tier\u00e4rztl Prax"},{"key":"10.15653\/TPG-151032-2","unstructured":"Baumgartner W.
