Dairy and meat cattle breeding plays a key role in modern society, providing people with raw materials obtained from cattle in the form of primary or secondary products. The purpose of our study was to establish the interdependence of glucose and hemoglobin content with indicators of the reproductive capacity of cattle. Glucose content was determined in the blood serum of cattle, and hemoglobin content was determined in venous blood using a LabLine-010 spectrophotometer (Austria) using a set of reagents manufactured by SpinLab (Ukraine). Statistical calculations of the obtained data of biochemical analysis of blood serum of cattle were performed using the Microsoft Excel program. According to the results of the study, the interdependence of the hemoglobin content with the service period was established, which is an average positive correlation dependence r = (0.549) (P ≤ 0.001) and a strong negative correlation dependence r = (-0.701) (P ≤ 0.001) with days to the 1st want to Glucose content has a strong negative correlation r = (-0.722) (P ≤ 0.001) with the insemination index, a strong positive correlation r = 0.727 (P ≤ 0.001) with the service period and an average positive correlation r = 0.520 (P ≤ 0.001) with days until the 1st birth. According to the obtained results, we established that the content of hemoglobin and glucose in the blood serum of cattle has a correlation dependence with indicators of reproductive capacity: service period, days to the 1st heat and insemination index. Our hypothesis is confirmed by the results of univariate variance analysis. Prospects for further research are the use of drugs to correct biochemical indicators with their influence on the reproductive capacity of cattle.
