Abstract

Studies have established that the highest monthly milk yield in cows of all groups was noted in the third month of lactation. In this month of lactation in cows of the III group with a live weight of 481 kg and more, the monthly milk yield was, respectively, 44 and 24 kg higher than in the peers of the I and II groups. The highest monthly milk yield of cows of groups I, II and III was, respectively, 12.33%, 12.37% and 12.53% of milk yield per lactation. Studies have confirmed that the level of payment for feed with dairy products is closely related to the level of milk production of cows. The cost of feed units for milk production in high-yielding cows is noticeably lower than in less productive peers. It was also found that the use of mobile mobile milking machines contributes to the complete milking and the manifestation of the potential of milk productivity of Holstein cows.

Highlights

In the context of increasing the production of livestock products, it is important to use the potential of the leading breeds of the world gene pool and identify opportunities for improving productivity, taking into account various factors [1,2,3]
The identification of the relationship of live weight at the first calving with further milk productivity is important for the further effective use of the potential of cows and is relevant [10]
Studies have shown that the level of milk production of cows depends on the live weight at the first calving (Table 1)

Summary

Introduction

In the context of increasing the production of livestock products, it is important to use the potential of the leading breeds of the world gene pool and identify opportunities for improving productivity, taking into account various factors [1,2,3]. Among the breeds of dairy cattle in the world, the Holstein breed is recognized as the leader [4] The cattle of this breed are distinguished by extremely high milk productivity and suitability for use in modern high-performance milking installations, with good adaptability to various soil and climatic conditions and other valuable qualities [4, 5]. Due to these valuable properties, Holstein cattle are widely used in many countries of almost all continents of the world [6]. The identification of the relationship of live weight at the first calving with further milk productivity is important for the further effective use of the potential of cows and is relevant [10]
