Purebred stud bulls of a related Holstein breed are widely used when breeding domestic black-and-white cattle breeds. Results’ evaluation of using these stud bulls by offspring quality is relevant and has practical significance. Stud bulls of the Vis Back Ideal 1013415 line were evaluated in one of the breeding farms of the Moscow region. As a result, it was found that all the evaluated stud bulls had a high breeding value. Bulls Trubach 174 - A1; Nog Odin-M 490626 - A1; Lowlands-M 427373367 – A2 were assigned categories by milk yield, bulls Memory-M 54215651 – B2; Fern-M 107901925 - B1; Lowlands-M 427373367 – B1. The evaluation of nutrients’ yield with milk showed that when using the offspring of Memory-M 54215651 bull, negative results were obtained despite that it has a category B2. According to the nutrients’ yield with milk. Thus, stud bulls of the Vis Back Ideal 1013415 line: Trubach 174; Nog Odin-M 490626; Memory-M 54215651; Fern-M 107901925; Lowlands-M 427373367 can be used on the farm considering their breeding value. Lowlands-M 427373367 bull with category A2 B1 requires wider use.
