Lischer, C J; Dietrich-Hunkeler, A; Geyer, H; Ossent, P (2000). Untersuchungen über die klinischen und biochemischen Befunde bei Milchkühen mit unkomplizierten Sohlengeschwüren unter Berücksichtigung der Klauenrehe als prädisponierenden Faktor. Schweizer Archiv für Tierheilkunde, 142(9):496-506.

Abstract

A total of 160 dairy cows with no signs of systemic disease that were treated for an uncomplicated claw lesion with exposed corium were included in this study. The clinical findings of the orthopedic examination were compared with the biochemical profile. The cows with a mean age of 7.4 ± 2.6 years had an average milk yield of 6188 ± 1174 litres (data from previous lactation). Cows with the same or a higher milk yield than the herd average were over-represented (72%). Almost half (45%) of the cows were in the second half of their lactation when examined (5.9 ± 4.1 months). A total of 236 lesions were recorded. Twelve (7.5%) of the 160 cows had 3 or more lesions, 49 (30.6%) cows 2 lesions and 99 (61.9%) cows one lesion.The most common localisation of ulceration were at the outer hind claw at the typical site in the sole (62%) and in the wall (17%). The alterations of the exposed corium were either classified as slight (63%), moderate (22%) or severe (15%). Changes attributed to laminitis were observed in two thirds of all animals (subclinical 36%; clinical 30%). The concentration of glucose, cholesterin, LDH and urea was increased in one third of the animals. Phosphorus and magnesium concentrations were lower than the reference values in 43%, and 23% of the animals, respectively. Cows with a history of former claw lesions in a previous lactation, with laminitis, with more than one moderate to severe claw lesions and cows with acute lesions had higher urea concentrations than the respective control group. Blood levels for AST, bilirubin, creatin-kinase were higher and iron lower, respectively, in cows with moderate to severe claw lesions than in cows with mild lesions in only one claw. The fact that cows with more than one chronic claw lesion had a higher incidence of alterations in the blood chemical profile than cows with mild claw lesions in only one claw indicates that severe claw diseases occur concurrently with metabolic disorders or vice versa

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
