In the production of livestock and other products, productivity depends on adaptive properties of the animal organism to environmental factors. At the same time, the most important indicators of adaptive characteristics are quantitative and qualitative indicators of the sperm productivity. At the same time, within a year, depending on seasons of the year, some clinical indicators of the body also differ, however there is correlation between these two factors. The study of these issues in the conditions of Uzbekistan and its findings can be used effectively in planning, organizing and managing this process. It is known that pedigree bulls-sires of cattle are imported into the republic (except for pedigree bulls of the Bushuev breed). In the course of our experiments, seasonal changes in the seed productivity of sperm donors of imported young bulls and local Bushuev bulls were studied by comparing some of their physiological indicators. It is due to the fact, that one of the indicators directly related to the level of productivity of animals is their physiological state of body. Of course, it is important to calculate clinical indicators, because it is on the basis of this information that it can be assumed that the animal is adapted to a particular environment, and its seed production is expected in the near future.
