Statistical assessment of the concentration of anti-Muller hormone and biochemical parameters of the blood of donor cows in the luteal phase of the cycle

Abstract

Increasing the productivity of cows in the modern world is a key aspect of animal husbandry.  Embryo  transplantation  in  cows makes it possible to increase the production of genetically valuable animals and improve the breeding qualities of the herd. One of the methods  for  determining  the  activity  and reserve of the ovaries is the determination of anti-Muller  hormone  in  the  blood.  AMH plays an important role in the regulation of reproductive  function  in  animals,  including cows. High levels of AMH may indicate a good reserve capacity of the ovaries, which may  be  useful  when  choosing  animals  for breeding.  In  the  presented  study,  the  bio-chemical parameters of the blood of 9 Holstein cows in the luteal phase were analyzed. A direct correlation of a high degree (0.89 and  0.89,  respectively)  was  found  between the AMH level indicator and urea and urea nitrogen  indicators.  There was  a direct noticeable correlation between the AMH level and the serum creatinine level (0.63). Also, when  assessing  the  indicators  of  mineral metabolism,  strong  correlations  were  revealed:  negative  when  comparing  the  level of  AMH  with  the  level  of  calcium  (-0.71) and  positive  when  comparing  the  level  of AMH  with  the  level  of  phosphorus  (0.78). The regulation of the synthesis of AMH itself and its metabolic effects have been studied little, there is only a limited amount of data on the relationship of the hormone with other factors of autocrine and paracrine regulation. For a more accurate understanding of this correlation and its significance, additional research is needed.
