METHOD OF ASSESSING GENOME STABILITY AND PRODUCTIVE INDICATORS OF YOUNG MINK WHEN USING NONCONVENTIONAL FEED ADDITIVE DRY PALM FAT IN DIETS Russian patent published in 2023 - IPC A01K67/00 

FIELD: biotechnology.

SUBSTANCE: invention is a method of assessing the stability of the genome of young mink grown for skins, when used in diets of a new non-traditional feed additive — dry palm fat including the use of a micronucleus test — determining the frequency of occurrence of erythrocytes containing micronuclei in the peripheral blood of young mink which establishes the relationship between this indicator and the feeding factor, the physiological state of clinically healthy animals of this direction of productivity, which makes it possible to increase the effectiveness of assessing the effect of dry palm fat on the productive indicators of young minks.

EFFECT: when using in the diet of young mink an unconventional feed additive — dry palm fat during the formation of winter hairline (in October-November), it was found that an increase in the frequency of occurrence of erythrocytes containing micronuclei in the blood of males at the age of 7 months to an average level of 14.6±3.18% o (per mille) is associated with a change in the composition of the diet, correlates with a large increase in live weight while maintaining morphological and physiological characteristics and is aimed at realizing the productivity of young animals — increasing the area and quality of skins.
