Sažetak:
Selection of cows for high milk production resulted in reduced resistance of animals to various diseases such as udder inflammation, which is also a consequence of udder maladjustments for mechanical milking. Studying of milk flow and application of modern measurement devices could lead to higher number of cows adjusted to mechanical milking and reduce udder disease risks. Milk flow in mechanical milking of cows consists of several different phases that can differently affect not only the length of milking, but also the udder health. The aim of the research was to evaluate effects of starting milk flow duration (TS 500) on udder health. The research was carried out on 457 Holstein cows. Udder health (logarithmic somatic cell count) was at the greatest risk in cows being in the third lactation (LSCC=3.17 ± 0.12). Starting milk flow (TS 500) was equable through all lactations, being the longest in cows in the second lactation (0.21 ± 0.01 min). The least effect on udder health (LSCC=2.38 ± 0.23) when TS 500 was comprised between 0.31 and 0.40 min. Longer as well as shorter duration of starting milk flow resulted in significantly higher number of somatic cells in milk of Holstein cows.
