That is however closely connected to longevity and especially to the lenght of productive life, which are the deciding factors as the priority is to maintain cattle farming cost effective. The purpose of this work was to research factors that influence production, reproduction and longevity of holstein dairy cattle. One part is deals with observing and analysing herds of holstein cows from two different farms. Collected and analysed information about production, reproduction and life expectancy were compared using appropriate statistical methods.
