Comparison of somatic cell count measurement in milk obtained by electronic and microscopic methods

Abstrakty
The somatic cell count (SCC) is a commonly accepted index of udder health and for this reason the correct result of the measurement is so significant. The aim of the study was a comparison of the results of SCC measure in the milk from the same cows, obtained by electronic and microscopic (reference) method performed in two different laboratories. The samples measured in the university laboratory were delivered several hours after sampling and immediately investigated, but the parallel samples directed to the official milk laboratory had usually been examined two or three days later. The results of these examinations obtained in the official milk laboratory were higher in many cases (even by 1402.8%) in comparison to results obtained at the university laboratory. To additionally verify this variance of SCC, samples examined in the university laboratory had also been calculated using the reference (microscopic) method. The verification has confirmed a high percent of compatible results obtained in the university laboratory with both of the methods in contrast to their considerable divergence in the official laboratory. The reason of these divergences is probably the different lapse of time between sampling and examination in both of the laboratories.
