One of the main tasks that are aimed at improving the milk production of animals is to

create optimal conditions for their maintenance, which will increase the use of their genetic

potential on the basis of the implementation of engineering and technological factors.

The scientific and economic experiment was aimed at determining the amount of dust that

changes its working parameters when it enters the pulsator.

It has been determined that the dust content in the air below 10 mg/m3 almost does not affect

the pulsator rate. The dust content of 20-25 mg/m3 reduces the pulsation rate from 60±5 to 45±5

cycles per minute or by 33.3%. Changes in the parameters of the pulsator operation take place

within 10 days. The dustiness of 30-35 mg/m3 reduces the pulsation rate from 60±5 to 35±4 cycles

per minute on the 7th day of the pulsator operation or by 71.4%. At a concentration of dust in the

air more than 35 mg/m3 , the pulsators clog within 2 days, and their further work is impossible

without cleaning. In terms of volume of milk yield, a group of high-yielding cows with a pulsation

rate of 86-95 cycles per minute probably surpassed the analogues from the group with a pulsation

rate of 40-55 cycles per minute by 2.15 kg or by 25.9% (P<0.001). In addition, the pulsator rate of

71-85 cycles per minute was also likely to affect the amount of milk yield compared with a pulsation

rate of 40-55 cycles per minute by 2.24 kg, or by 27.0% (P<0.001). As the milk yield was reduced

with a pulsation rate of 56-70 cycles per minute, these differences were equal to 1.14 kg or 13.7%,

at P<0.01. At least, the pulsation rate of 86-95 and 71-85 cycles per minute probably influenced the

amount of milk yield from the cows at a pulsation of 56-60 cycles per minute by 1.01 and 1.10 kg,

or by 10.7 and 11.6% respectively (P<0.01 in both cases). In the process of statistical processing of

machine after-milking indices, a slightly different situation was revealed. Thus, the pulsation rate of

40-55 and 86-95 cycles per minute slightly affected the volume of milk yield as compared with the

pulsation rate of 56-70 cycles per minute in 2.7 and 2.1 times, but this difference turned out to be

probable (P<0,05) as well. In its turn, the amount of the machine after-milking for these levels of

the pulsator was also highly probable as compared with the pulsation rate of 71-85 cycles per

minute in 2.6 and 2.0 times respectively (P<0.01). At the same time, the value of manual after

milking using the vast majority of operating modes of the pulsators was also highly probable as

compared with the pulsation rate of 56-70 cycles per minute (P<0.001 in all the cases). Moreover,

the amount of milk obtained in manual after-milking mode at 40-55 and 86-95 cycles per minute

turned out to be probably higher in contrast with a similar pulsation rate of 71-85 cycles per minute

(P<0.001).

Keywords: dust, air, pulsator, pulsation rate, milk yield indices.
