The development of modern animal husbandry is quite an urgent issue today, because the consumption of dairy and meat products is growing rapidly. Factors affecting reproducibility play a key role in this issue. The aim of the work was to investigate the dependence of the content of calcium and phosphorus in blood serum with indicators of reproductive ability in cows. A spectrophotometer was used to study calcium and phosphorus content. A correlation dependence of the calcium content with the insemination index was established, which is a moderate positive correlation r = 0.494 (Р ≤ 0.001), with the service period – an average positive correlation r = 0.643 (Р ≤ 0.001) and days to the 1st heat – a strong positive correlation r = 0.862 (Р ≤ 0.001). Phosphorus content has an average positive correlation with the service period corresponding to r = 0.599 (Р ≤ 0.001), with the insemination index had the smallest correlation, which is r = 0.314 (Р ≤ 0.001) and the duration of days to the 1st mating has a very strong positive correlation, which is r = 0.909 (Р ≤ 0.001). Based on the obtained data, we can testify about the dependence of calcium and phosphorus content with indicators of reproducibility, such as insemination index, service period and days to the 1st heat. What gives reason for further research with the establishment of the interdependence of the reproducible ability during its correction from the side of influence on elements that have a correlation dependence with these indicators.
