Abstract
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.
Highlights
Milk production at dairy complexes is the first stage in obtaining dairy products, so milk quality depends on how the production technology is organized (Habtamu et al, 2018)

The ‘DeLaval’ system’s operation is as follows: when the intensity of milk ejection is reduced to 200 ml/min at the beginning and end of milking, the milking machine works in a gentle mode
Summary
Milk production at dairy complexes is the first stage in obtaining dairy products, so milk quality depends on how the production technology is organized (Habtamu et al, 2018). The intensity of milk ejection is an animal’s individual property; it affects the time spent on milking, milking’s completeness, and, production costs (Paliy, 2019). The intensity of milk ejection determines the cost of labor and time to obtain one quintal of milk. This indicator’s improvement provides a tremendous economic effect (Ivanyos et al, 2020). It is established that the milk reflex in cows is a complex process that occurs in two phases. Pulses through the afferent nerves reach the spinal cord, where the nerve impulses switch to the efferent pathways, which, reaching the mammary gland, provide the secretion of cysteric milk due to the relaxation of the sphincter of the teat. The afferent pathway approaches the neurohypophysis, where afferent impulses promote the release of the hormone
