Milk production process, quality and technological properties of milk for the use of various types of milking machines

Abstract

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.

Establishing an interconnection between the technical and technological parameters of milking equipment based on the movement of a milk-air mixture in a milking machine

“…Our studies of the process of moving the milk mixture in the milking machine are consistent with those reported by other authors earlier [21][22][23][24] and complement them. A significant difference in the methodological plan of the conducted research was that an opportunity was created to study a wide range of indicators -from technical to technological.…”

Comparative Analysis of the Degree of Technology in Family Dairy Under Stable and Mixed Management Systems. Case Study

“…These two technologies are considered basic and it is likely that the (mixed) production system does not facilitate the use of the milking machine, because it requires electricity or fuel, but it requires adequate facilities for its correct operation and having close to cows for efficient use. Lutsenko et al (2021) mentions that the proximity to the milking area and the type of facilities in which it is milked, especially if mechanical milking is used. However, in the case of mechanical milking, the management of the milking machine also influences the productivity of the cow, especially due to the influence on the health of the udder and the presence of aerobic bacteria and proliferative anaerobic microorganisms in the milk.…”

Justifying parameters for the automatic servo control system of a rotary plate vacuum pump in the milking machine

“…The analysis of the condition of milking equipment [15] showed that the system for providing servo control of vacuum pumps should solve the following tasks:…”

“…However, the cited papers [15,16] do not fully define the expediency of using an automated servo control system of a rotary plate vacuum pump and, in accordance with this, ways to address it.…”
