METHOD FOR DETERMINING COW MILK PRODUCTIVITY Russian patent published in 2019 - IPC A01K67/00 

FIELD: biotechnology.

SUBSTANCE: invention is a method for determining the milk productivity of cows per day, including sanitary preparation of the udder, inducing the milk ejection reflex before milking, following the rules of machine milking of animals suitable and accustomed to machine milking, during control milking, determining the amount of milk, sampling milk and analyzing fat and protein content in it per day, where determining the amount of milk and analyzing are carried out separately for each milking, then the milk quantity and its content of fat and protein per day is calculated, then the coefficients of recalculation of the amount of milk and the mass fraction of fat and protein are calculated for each milking into daily indicators, while during the year, one control milking per day is carried out for subsequent determinations of the milk productivity of cows, and according to its indicators, multiplied by the calculated coefficient corresponding to it, the same indicator is calculated per day with uniform feeding, maintenance and milking, where, with unequal time intervals between milking per day, milk productivity is more accurately determined by a single milk yield after a longer period between milking, while dairy cows are taken from the tenth day of lactation and more to determine milk productivity.

EFFECT: invention allows to reduce labor costs and working hours of operators and technicians to determine the milk productivity of cows per day, as well as reduce the stress load on animals.
