Studies have been carried out to evaluate the efficiency of using easy-assembled cow houses in modern milk production technologies for the use of high-productive milking plants of the type ‘Parallel’ and ‘Carousel’ with 32 machines each. It has been established that new types of premises not only provide comfortable conditions for the maintenance of highly productive cows, but also reduce the labor costs for their maintenance and, most importantly, allow the use of modern high-productive milking installations of the type ‘Parallel’ and ‘Carousel’. It has been established that the technology of preparation of cows for milking and milking technology provides more complete display of the milk ejection reflex at the installation of the ‘Parallel’ type. The average intensity of cows’ milk flows at this plant is 30% higher compared to those of the installation of ‘Carousel’ type, which is confirmed by the intensity of milk flow production at the first minute of milking, which is at the level of 2.97 against 1.85 kg min.-1 per installation of ‘Carousel’ type. Milk obtained using a milking installation of the ‘Parallel’ type has higher values of the mass fraction of fat and protein that is associated with the genetic potential of animals. According to physical, chemical and technological properties, milk obtained from milking installations such as ‘Parallel’ and ‘Carousel’ is within the limits of the standards in force. Milk obtained from the use of milking equipment such as ‘Carousel’ has higher electrical conductivity at the level of 4.6 mS cm-3, which is confirmed by a higher level of mastitis disease of cows. Due to bacterial contamination, reductase test and milk clot characteristic, milk obtained using a milk installation of ‘Parallel’ type also has higher quality indicators than the installation of ‘Carousel’ type. But according to the complex of indicators, milk obtained from various technologies of milking refers to the desired cheese-making class.

High productivity of dairy cows in the conditions of new innovative technologies can not be obtained without providing comfortable conditions for their functioning.In this connection, the conditions for maintaining high-yielding cows in various types of livestock buildings are investigated: the traditional, 24.0 m wide and new unassembled, 32.5 m wide and 36.0 m in extreme periods of the year. The different width of the premises is due to the need to use different types of milking plants: MilkProud, Parallel, Carousel and robotic milking systems.Studies have established that volumetric-planning and technological solutions for easy-assembled premises increase the volume of space per head from 45.6 m3 to 96.3 m3 and 129.6 m3. It positively affects the conditions for the maintenance of highly productive cows. The presence in their design of side curtains and light-aeration ridge increases the speed of air in 3 times. This provides a reduction in the concentration of ammonia in 8 times, and bacterial pollution at 18.7 times compared with traditional barn.Increasing the volume of the room up to 129.6m³ per head reduces the bacterial air pollution in the winter period to a minimum value of 2.8 thousand/m³. New elements in the design of easy-assembled spaces provide resource-saving and organizing their lighting.According to the existing standards in Ukraine, the lighting in the feeding area should be at 52 lux. In traditional rooms, this level is achieved only by installing additional energy sources, which provide an increase in lighting from 31 lux to 52 lux. In new types of premises the required level of lighting is provided naturally, which leads to significant energy savings. It was established that technological solutions of easy-assembled premises provide comfortable conditions for recreation of high-yielding cows.In these types of rooms, the animals rest 12.4% and 20.0% more time compared to traditional rooms. Feeding of cows in easy-assembled premises from the stern table provides quick feeding of animals with feed. At the same time the time consumed for feed consumption in new types of barns is significantly less and is 252.0–246.0 min a day compared to 320.2 min in traditional premises where feeding is carried out from traditional feeding troughs.It is positive that in the new types of premises in animals there is a new important element of behavior – the movement, which they spend 8.6% and 9.9% of the time. New types of premises with resource-saving milk production technologies have a positive effect on the conditions for the maintenance of highly productive cows and can be widely implemented in Ukraine.

В статті представлено нові дані по якості функціонування легкозбірних корівників шириною 36 м і висотою 10,5 м, спроектованих з метою впровадження роботизованих систем доїння на фермі в 500 корів. Отримано експериментальні дані звивчення кратності доїння корів залежно від лактації, періоду лактації та їх продуктивності в умовах «мотиваційного» доїння, які засвідчують про фізіологічні аспекти цього процесу. Встановлено, що кратність заходу корів на доїння залежить від лактації по рахунку та продуктивності корів. Найменша потреба заходжень на доїння спостерігається у корів першої лактації, що пов’язано з більш низькою продуктивністю і меншою ємкістю вимені в цей період. При підвищенні продуктивності корів в наступні лактації збільшується і потреба корів у доїнні.

In despite of crisis situation in dairy husbandry, modern dairy farms with innovative milk production technologies and the use of high-performance milking plants of the "Parallel" and "Carousel" type are being created in Ukraine, which requires standardization of the livestock capita both on the exteriors and on indicators of suitability of cows for machine milking. The need for such research is also due to the fact that modern dairy farms are completed with a high productivity livestock cows with a milk yield of 8-10 thousand kg per lactation, which according to these criteria differ significantly from cows with average productivity. The livestock cows of modern dairy farms in Ukraine is completed at the expense of its own livestock capita of farmings and through the purchase of imported non-calving young cows. Therefore, the main problem when creating such farms is to complete their qualitative livestock capita from the point of view of its suitability for machine milking, which in the structure of the cost of construction of new farms is about 30%. It is established that the level of suitability of cows for machine milking on the created farms is different. Thus, at the Superadded liability company farming "Terezine" where the dairy farm is completed with Holstein cattle imported from European countries, the suitability of cows for machine milking is 95.7%. The farming "Ostriykivske" is completed with domestic livestock of black-and-white breed with the suitability of cows for machine milking 82.5%, which negatively affects the physiological state of cows, in particular, the morbidity of their mammitis. The level of morbidity of animals here is practically twice twice above than on the dairy farm completed with an imported livestock capita (25.3%). The analysis of the main criteria concerning the suitability of cows to machine milking showed that a significant part of cows did not meet the requirements of the "Rules of Machine Milking" (2004) on the basis of udder distance from the floor, the size of the teats and the uniformity of the development of the udder slices. If at the Superadded liability company farming "Terezine", where the dairy farm is сompleted with imported livestock capita, the suitability of cows under the form of udder, its distance from the floor, the size of lobules, the uniform development of the lobules of the udder, the duration of milking are within 94.5-98.7%, then on the farm with the domestic livestock capita it is equal to 80.3-82.5%. It has been revealed that in recent years, in Ukraine there is practically no qualitative selection and pedigree work. According to the economic reporting, the main reasons for roguing cows from the herd are barrenness, the disease of the mammary gland and extremities.The roguing of cows on the basis of their suitability for machine milking at farms practically is not carried out.

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.
