THE STUDY OF UNEVEN DEVELOPMENT OF THE UDDER QUARTERS OF THE ANIMAL

Abstract

Increasing the economic efficiency of machine milking is possible by using high-performance, partially and (or) fully automated milking units using advanced milking technologies. When milking animals with traditional milking machines, turning off the milking cups occurs simultaneously, without taking into account the uneven development of the udder quarters, this can eventually lead to dry milking of the udder quarters, which is fraught with consequences. To substantiate this issue, an analysis was made of the work of DeLaval milking robot in Timershik farm of Saba LLC in the Sabinsky district of the Republic of Tatarstan. The results of the study of uneven development of cow udder shares based on the processing of the data obtained showed that a large number of animals in the herd have uneven development of udder quarters, but they are superior in productivity to other cows and culling of these animals due to uneven development of udder quarters is excluded. In this connection, the method proposed by Safiullin N.A. for assessing the uniformity of development of udder quarters is considered, which consists in the following: after determining the number of milk yields by quarters, the coefficient of variation is calculated and the indicators of uniformity of development of quarters are calculated. In our opinion, this method of analysis is more effective. We also analyzed the milk yield curves for udder quarters and proposed a scheme of integral milk yield curves. The obtained curves once again prove that milk production in animals by udder shares does not end in the same way. Based on the data obtained, it can be stated that the development of a domestic automated milking machine with a quarter-turn shutdown of milking cups is an urgent task today. The obtained data are necessary for the development of a domestic automated milking machine with a quarter-turn shutdown of milking cups
