“…The milking rate is closely related to the amount of milk yield, milking duration, the level of vacuum pressure, pulsation rate, the ratio of suction and compression strokes, and other indicators. The intensity of the milking reflex, the completeness of milking, the quality of milk, the physiological state of the mammary glands, and the productivity of cows in general during lactation depend on the quality of performance of individual elements of the operation of milking and their interaction (Palii et al, 2020f;Shtepa et al, 2020). Scientific and economic experiments show that the milking technique affects milk productivity, composition, and properties of milk.…”

Improving modern dairy farming is based on the industry's development, which means transforming livestock farming into a competitive industry. The development of its technical and technological support is closely related to its functional ability to realize the genetic potential of biological objects of production with high-quality products, which is the defining criterion for the competitiveness of machinery and technology at the industry’s present stage of development. The purpose of the research was to study milk production technology based on a comprehensive assessment and implementation of modern milking equipment, maximizing animals’ genetic potential and industry efficiency. We proved that applying the ‘DeLaval’ milking parlor under the same feeding and keeping animals ensured the proper completeness of milking and increased cows’ milk yield. During the first, third, and highest lactations, the milk yield was 226 kg (P=0.05), 266 kg (P=0.05), and 214 kg (P=0.05), respectively. After-milking when applying ADM-8A averaged 175 ml, and only 45 ml when applying the ‘DeLaval’ parlor. When using the ‘DeLaval’ milking equipment, the milk production intensity of cows was 1.43 kg/min, and, with ADM-8A, it was 1.24 kg/min, which is 0.19 kg/min (P=0.001), or 15.3% higher.
