Abstract | The high level of cattle herd reproduction equally depends on the reproductive capacity of both females and males. One of the main ways of increasing animals’ productivity is qualitative herd transformation. Increasing livestock productivity in the country requires large-scale breeding based on the extensive use of genetic methods of evaluating the breeding value of the animals and the intensive use of high-value breeding males. Scientists have found that in animals, indicators of the reproductive ability are inherited, which makes regulated breeding possible. The work was performed at a peasant farm in the West Kazakhstan region of the Republic of Kazakhstan. The study was focused on stud bulls and bull calves of the Kazakh white breed of various genotypes. Reproductive indicators were studied, such as ejaculate volume, ml; activity, score; concentration of sperm cells in one ml, bln/ml; and the number of sperm cells inejaculate, bln.
