The goal of the graduation theses was a comparison of the hygenic quality of raw cows milk, it was expressed by the value of total bacterial count (TBC) and somatic cells count (SCC) in four breeds of milking cows using only postdipping (3 breeds) in comparison with breed using predipping and postdipping. The breeds differed in technology of lairage and milking procedures, grazing and the size the herd. During two seasons 2006 till 2007 was discovered that the breeds using predipping and postdipping had significantly less average values of TBC (9,46.103.ml-1) in comparison with the breeds using only postdipping (15,97.103.ml-1), the difference was statistically significant (P = 0,007) on the level of significance P < 0,05. Also it was shown that SCC were below averages levels with using predipping and postdipping (293,47.103.ml-1) in comparison to breeds using only postdipping (312,06.103.ml-1), the difference was also statistically significant (P = 0,01) on the level of significance P < 0,05.
