METHOD FOR CORRECTION OF PHYSIOLOGICAL AND BIOCHEMICAL STATUS, INCREASE OF MILK PRODUCTIVITY AND QUALITY OF MILK IN HOLSTEIN COWS IN WINTER STALL PERIOD Russian patent published in 2024 - IPC A23K50/10 A23K10/30 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used as a biologically active feed additive for correction of physiological and biochemical status, increase of milk productivity and quality of milk of Holstein cows in winter stall period. To increase activity of herbal blend based on black currant leaves and redhaw hawthorn fruits with correction of physiological and biochemical status, increase of milk productivity and quality of milk in cows under stressful conditions of industrial maintenance during winter stall period is used as an additional source of fatty acids, fat-soluble vitamins, as well as B vitamins, ascorbic acid, macroelements, microelements and organic acids – flax seeds and rosehips. Herbal blend is fed additionally to the basic diet of cows in the following composition g/head: black currant leaves 7, rosehips 7, redhaw hawthorn fruits 7, flax seeds 4.

EFFECT: achievement of reference values or approximation to them by a number of hematological and metabolic blood parameters in highly productive Holstein cows under stressful conditions of an industrial complex, which helps to reduce the negative effect of stress on the animal's body and correction of the physiological and biochemical status, which is an important condition for the formation of animal productivity.
