FREQUENCY OF COWS MILKING IS A WAY TO INCREASE DAIRY PRODUCTIVITY ON ROBOTIZED FARMES
The choice of technologyof machine milking is a task of primary importance at work of any dairycomplex, and studying of productivity of cows, at use of the modern milkingequipment, on the basis of one enterprise, now in due time and is actual.Robotic (in English – language works-automated) milking is a quite acceptablealternative to manual and mechanical milking and makes it possible to obtainproducts with a sharp reduction in manual labor costs in terms of populationreduction in rural areas. Studieswere carried out on Holstein cows imported from Germany, owned by KaluzhskayaNiva LLC, Ferzikovsky District, Kaluga Region, with a productivity of about8500 kg per lactation. The robots of the company “GEA FARM TECHNOLOGIES” (madein Germany) had a load of about 70 cows on the device. The cows werefree-standing. They had round-the-clock access to complete feed mixtures, whichbegan to be distributed at 21:00. During milking, concentrates were obtained atthe rate of 200 g per liter of milk. According to theresults of the research, it was revealed that the frequency of milking wasalmost evenly distributed over the periods of the day: the number of milkingsbetween the periods differed by no more than 20 %, and the only significant difference was between the periods of 0–4 hours and 4–8 hours. Statistically processed data received within 3 days, divided into 4-hour periods. The number ofmilkings changed little during the day: only in the period of 0-4 hours therewas a decrease in the number of milked cows and the value of one-time milkyields. The size of one-time milk yields practically did not depend on thelactation period and amounted to 7.19–7.65 l; only in thesecond month of lactation did it increase to 8.72 l. As the activity of themammary gland decreased, only the frequency of milking decreased.
