FIELD: animal science.
SUBSTANCE: the innovation in question deals with primary zootechnical and breeding record, monthly detection of the quantity and the quality of milk in mothers, daughters and contemporaries per all lactations, sorting selection groups and organizing tests in bulls on the quality of the offspring in stocks, breeds and regions. Additionally, in individual animals, stocks and breeds it is necessary to specify longevity; absolute - in months - and relative - in % against average in a stock and in a breed - age of the 1st fertilization; lifelong - absolute - in natural measurement - and relative - in % against average values - the gross and average annual output in calves and milk yield per 3 and next years of life. Based upon the data obtained one should determine adaptive breeding value in individual animals, stocks and breeds according to scale 1. The innovation provides the chance for more objective selection of animals for further usage.
EFFECT: higher accuracy and efficiency of detection.
