Abstract
The influence of machine stripping with semi-automatic milking units "Harmony" on milk quantity and chemical composition of milk was investigated. The investigation was made in a herd of 43 Black and White cows in lactation during 10 milkings. The milk quantities of main milkings and strip-pings were measured separately with an electronic measuring device. The composition of milk from main milkings and strippings was analysed separately. The average milk quantity from strippings was 0.73 kg per cow and milking, or 8.2% of the total milk. At average production of 6,500 kg milk per lactation, the milk yield would increase by stripping for about 535 kg per cow. The machine stripping increased milk fat from 3.67% to 3.81% in the total milk. A significant influence of stripping was established on FCM, milk fat, proteins and total solids quantity.
