METHOD FOR ASSESSING STRESS RESISTANCE AND SELECTION OF TECHNOLOGICAL-TYPE COWS FOR ROBOTIC MILKING Russian patent published in 2023 - IPC A01K67/02 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology. The invention is a method for assessing stress resistance and selecting technological-type cows for robotic milking, including taking into account the milk ejection reflex according to the intensity of milk excretion, the rate of milk production, before and after stress on the animal. The number of milkings is determined, after which the recovery of the intensity of milk excretion at the level of the average and above the average value before stress occurs, and when the number of milkings is more than the average for the herd by 1 sigma (M + 1σ), they are classified as animals of a high type of stress resistance, less than the average for the herd by 1 sigma (M - 1σ) to a low type of stress resistance, with an intermediate value - to an average type of stress resistance, where M is the arithmetic mean of the indicator; σ is the standard deviation of the indicator, determine the time interval after which the recovery of the rate of milk formation occurs at the level of the average and above the average value before stress.

EFFECT: invention makes it possible to increase the efficiency of assessing the type of stress resistance and selecting cows for robotic milking with the desired characteristics.
