Dairy productivity of cows and milk quality with various technologies of keeping and milking

The article presents the results of studying dairy productivity and milk quality with different technologies of keeping and milking cows. The average milk yield of cows for lactation when using robotic milking was 9,350 kg, in the milking parlor it was 9,212 kg, and in a tied housing system it was 8,960 kg. The average productivity of cows during lactation when milking in a tied housing system into a milk pipeline is 390 kg lower than with a robot, and 252 kg lower than on a ‘Europarallel' milking machine. The mass fraction of fat during milking in a tied housing system averaged 3.65%, in the milking parlor it was 3.70% and with a robot it reached 3.75%. The smallest number of somatic cells was observed while using robotic milking (on average, 140 thousand/cm3 per lactation), and the most significant number was in in a tied housing system (350 thousand/cm3). When determining the efficiency of using cows with different milking techniques, it was found that the milk yield of cows while using robotic milking in terms of the basic mass fraction of fat in milk (3.4%) is 102 centners, which is 2.3 centners (2%) more than the milk yield in the milking parlor and 5.8 centners (6%) more than in a tied housing system. The cost of milk production during robotic milking compared to milking in a tied housing system is 10% higher, and compared to milking in a milking parlor it is 13% higher.
