Abstract

Analysis of blood cells is an important part of many scientific investigations in the field of cattle herd health. Over the last 30 years, automated blood analysis has all but replaced manual counting of blood cells using counting chambers. The present study investigated the effects of prolonged storage and storage temperatures on cell counts as determined by a haematology analyser. Blood samples from 20 clinically healthy cows were repeatedly analysed with a Cell-Dyn 3500 (Abbott Diagnostika, Delkenheim), within 24 hours after collection and after storage at either 4° C or 20° C. The counts of most blood cells were more stable in samples stored at 20° C than those stored at 4° C. For at least 8 h, the counts of all analysed cell types, with the exception of lymphocytes, remained within ±3 standard deviations that were calculated for fresh samples, provided that the blood was stored at 20° C.

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.
