The interrelation of the productive potential of cows with the degree of its realization in different technological conditions

The aim of the research was to determine the impact of milking technology on the degree of realization of the genetic potential of cows’ productivity. The studies were carried out on the basis of JSC "Voskhod" of the Sharkansky district of the Udmurt Republic. For research, 2 farms were selected with different milk production technologies: using a milking parlor of the "Carousel" type and a linear milking machine. The object of the research was cows of the Kholmogory breed born in 2016. The studied livestock was divided into 7 groups, depending on the level of genetic productivity potential (GPP) for milk yield. Cows with a lower GPP (7500-8000 kg) had a higher degree of realization and use of the genetic potential (RGP and UGP) compared to the cows with a high GPP (10500-11000 kg) with both milking technologies. It has been established that animals with a lower GPP of milk productivity realize it more fully under conditions of milking on a linear milking machine, and, starting from a productivity potential of more than 8500 kg, the best manifestation of hereditary productivity is noted when milking on the Karusel. In general, the higher the GPP in cows, the lower the degree of its implementation with both technologies. With loose housing and milking of cows in a milking parlor of the "Carousel" type, the level of GPP over 8500 kg of milk is better realized by 7.2-11.9 % than when using a tie-down technology and milking cows in a linear milk pipeline.
