Abstract

Cows’ milk productivity determining method of includes: determining the amount of milk during control milking, milk sampling and analyzing its fat and protein content for each milking, they are the same indicators for the day; calculating the conversion coefficients of milk amount and the mass fraction of fat and protein for each milking into daily indicators. Then one control milking is performed per day, and the same indicator is calculated for the same type of feeding, maintenance, and milking based on its indicators multiplied by the Corresponding coefficient. The time intervals between milking being unequal, milk productivity is more accurately determined by a single milk yield after a longer interval between them. For this method, milk cows are taken from the tenth day of lactation and more. The method allows reducing labor costs and working hours of operators and laboratory assistants to daily determine the dairy productivity of cows, as well as to reduce the stress load on animals.
