Some factors affecting milk somatic cell count
ŠPIKLOVÁ, Hana
The aim of this thesis was to compare somatic cells count (SCC) in milk depending on certain factors (month, milk system, lactation). Besides of SCC, also other parameters of milk quality were monitored. Milk sampling took place for 11 weeks in 2017 and samples were taken from 15 milked cows of the Czech Simmental breed. During the milk sampling were used two different parameters of pulsation. Pulsation adjustment significantly shortened the time of milking from 7,34 minutes in average to 6,19 minutes in average (P<0,001). After pulsation adjustment the SCC decreased from 188,000/ml to 154,000/ml as well, however, differences were not statistically significant. Concerning other factors the SCC was mostly affected by the number of lactation (P<0.01), primiparous cows had significantly lower values of the SCC (45,000/ml) that multiparous cows (237,000/ml).
