EFFICIENCY OF DIFFERENT MILKING SYSTEMS USAGE UNDER CONDITIONS OF RESOURCE-SAVING TECHNOLOGIES OF MILK PRODUCTION

Abstract

The article presents the efficiency evaluating results of easily build cowsheds in modern milk production technologies and the use of high-productive milking plants such as "Parallel" and "Carrousel" with 32 machines each and robotic milking systems. It has been established that the new type of premises not only provides comfortable conditions for keeping high-yielding cows, but also reduces labor costs for their maintenance and, most importantly, allows the use of modern high-productive milking plants such as "Parallel" and "Carrousel", as well as the usage of “motivational milking” technology". It has been established that the technology of preparing cows for milking and milking technology provides more complete realization of milk ejection reflex at the installation of the "Parallel" type and robotic milking system. The average intensity of cows’ milk flows at these plants is 30% and 47% higher compared to those of the installation of “Carrousel” type, which is confirmed by the intensity of milk flow production at the first minute of milking. The multiplicity of cows’ milking of different lactations under conditions of "motivational milking" depending on their productivity and lactation period was also studied. It has been proved that the higher the daily yield, the more often the cow goes to milking. Thus, animals with a daily milk yield of 10 to 20 kg go to milking in average of 2.34 times a day, and with a daily milk yield of 40 and above - 3.39 times. It has been deemed that milk obtained with the help of a milking parlor of the "Parallel" type and a robotic milking system has higher values of mass fraction of fat and protein, which is associated with the genetic potential of animals, their diet and quality of milking. According to physical, chemical and technological properties, milk obtained at the milking parlors "Parallel" and "Carrousel", as well as robotic milking systems meets current standards. Due to bacterial contamination, reductase test and milk clot characteristics, milk obtained with a Parallel milking parlor as well as the robotic milking system has higher quality indicators than with the use of the Carrousel type installation. But according to a set of indicators, the milk obtained by the studied milking systems belongs to the desired class of cheese.
