Features of antimuller hormone concentration and biochemical parameters of blood of donor cows in the follicular phase of the reproductive cycle

Determining the follicular phase of the estrous cycle is a critical task for successful artificial insemination, embryo transplantation, and egg washing in cows. The existing methods for determining this period are not ideal and have a number of limitations. Laboratory diagnostics plays a key role in modern animal husbandry. Monitoring of reproductive status, monitoring of metabolic processes, and assessment of feeding quality are critical control points during both routine medical examinations and specialized examinations of high–value animals. For the most part, reproduction control may consist in determining progesterone levels, diagnosing anestrus, and identifying the most optimal time for insemination. One of the markers of routine assessment of reproductive status may be the anti-muller hormone. Determining the level of anti-Muller hormone (AMH) seems to be a promising tool for monitoring reproductive status, especially in large herds, however, additional study of this hormone is required for a more accurate understanding. In the presented study, the biochemical parameters of the blood of 9 Holstein cows in the follicular phase were analyzed. A high degree of direct correlation was found between the AMH level and serum creatinine and phosphorus levels (0.75 and 0.78, respectively). An inverse correlation of a noticeable degree (-0.63) was found between the level of AMH and the level of serum AsAt activity. The study of the synthesis, regulation and metabolic effect of AMH continues, data on its relationship with other regulatory factors are limited. Additional research is needed to better understand this correlation and its significance.
