Особенности доения коров при эксплуатации автоматизированных систем доения "Astronaut A4"

Studied the physiological characteristics and technological properties of cows for the use of automated milking systems "Astronaut A4" company "Lely" (the Netherlands). It is established that cows can be milked, both day and night, while in the daytime the most active cows visit the milking station 1-2 hours after the distribution of partially mixed feed ration. The decrease in attendance was noted for 1-2 hours before the distribution of poop. The average visit of the robot milker is 3.1±0.08 times a day, while animals with an average daily yield of 24.2±2.7 kg were milked 2 times a day, 32.4±1.1 - 3 times, 39.4±2.3 kg - more than 4 times a day. The average length of stay of cows in the milking station is 8,02±0,18 min varying from 4,07 to 14.37 min. Preparation of udder takes an average of 2.22±0,07 min with the vibrations from 1.14 to 5.82 min 56,3% of the animals are milked dry for the first 6 min of milking, which is insufficient for effective use of robotic milking machines. Thus, for effective use of the voluntary milking system, the selection and selection of animals taking into account technological indicators becomes of particular importance.
