Physiological Justification of Udder Emptying in Highly Productive Cows

This study encompasses to measure frequency of physiologically motivated emptying the udder by Holstein cows during lactation. With recording hours day, experiment shows that first-born emptied udder, on average, almost three times a having second lactation 2.5 and 3rd 4th lactations or more day. Analysis daily attending robotic milking machine showed visitation was relatively even, except for maximum peaks from 11.00 12.00 o’clock 21.00 23.00 o’clock. Similarly, among 2nd there were two – at night 22.00 1.00 o'clock in day 17.00 o'clock. For lactation, - one night, afternoon. Cows under had high maxima: first 4.00 10.00 afternoon, third 18.00 night. concludes milk productivity needs (milking) least Since occurs time it is necessary provide animals with adequate water feed table.
