In Latvia, number of dairy farms that use automatic milking systems increase. The study was conducted in farm, where new cowshed was built, milking robots and herd management system was installed in 2014. The aim of the study was to evaluate milk yield, composition and quality when cows are milked in automatic milking system. The average milk yield per cow showed significant increase in each year of the study, and in 2017, it reached 9359.1 kg that is by 1779.5 kg more than in 2015 (p is less than 0.05). During the study, average somatic cell count (SCC) showed significant decrease from 138.3 thous. mLE-1 in 2015 to 75.2 thous. mLE-1 in 2017. The increase of milk productivity was observed in both primparous and older lactation cows, thus indicating that milk yield increases mainly due to new keeping conditions. In addition, new keeping system secures the possibility to register the amount of eaten fodder, as well as determines daily the changes of milk yield and composition.
