Abstract

The aim of the study was to show some of the basic milking properties and the appearance of the milk flow curve and its components in Jersey cows. The average duration of the main and the whole milking was 5.99 and 10.13minutes, respectively. The average milk flow was 2.01 and the maximum milk flow was 3.09 kg / min. A slightly longer duration of the ascending and descending phases compared to the plateau phase of the milk flow curve was found. A slightly higher prevalence of desirable milk flow curves was recorded, the presence of which is a good indicator of udder health status. Cows with more desirable milk curves had a higher total amount of milk, and a higher amount of milk in the first, second and third minutes of milking. Furthermore, it was found that cows had a relatively fast milk ejection, and within one minute achieved a milk flow of 0.5 kg / min regardless of the appearance of the milk flow curve. Further research is needed on a larger number of animals in order to obtain the best possible conclusions about the milking of Jersey cows.
