Abstract: The causes of the disposal of the animals and the main milk productivity
indices of cows having different genotypes depending on the method of housing and
technology of milking have been analyzed. For all the evaluated periods the animals
which were milked with a robotic system in the free stall barn surpassed the cows which
were kept on a leash and milked into the pipeline with the help of milking machines.
Along with this, in the cows kept in the free stall barn the limb diseases caused culling
more often than in other groups of animals under study.
Keywords: black-and-white breed, Simmental breed, milking technology, housing
method, milk productivity.
