Influence of some factors on milk flow and udder health status in two different cattle breeds.

Abstract

In this study were analyzed average daily milk flow and udder health status (by somatic cell score) in dairy cows. A total of 100 Holstein (H) and 48 Slovak Simmental (SS) cows were investigated. The Holstein cows had average daily milk flow significantly higher by 1.24 kg/min and somatic cell score (SCS) by 0.5 higher than Simmental cows. The factors like breed, parity, rear teat canal length and front teat canal diameter had a significant effect on milk flow but no significant effect on SCS. Thus, these results indicate differences between breeds and parity in milk traits and health status.
