The number of anthral follicles is positively and highly associated with the concentrations of anti-mullerian hormone (AMH) in cows. Therefore, in the determination of the ovary reserve, it can be used as a biomarker for determining criteria such as oocyte quality, superovulation response, fertility, performance life. This study aims to identify possible relationships between serum AMH levels and fertility parameters in cows and cows. In the study, 44 dwarfs and 40 cows were used as material. The first seed pregnancy rate in cows, the average number of seed per pregnancy, the pregnancy rates in groups in postpartum 200 days, the number of open days were analyzed as fertility parameters. The number of pregnancies in the first seed of the seed, the second and third seed pregnancies of the non-heed, the pregnancy rates of the two groups and the average number of seed per pregnancy were compared. The low AMH level in cows and cows was 0.001 ng/ml and the high level was 0.7 ng/ml in both groups. The average AMH level in cows and cows was determined as 0.26±0.17 and 0.21±0.16 ng/ml±SD respectively (p>0.05). After the AMH measurements, there was no significant relationship between the average AMH levels of those who were pregnant in the 1st, 2nd or 3rd seed in crowns and crowns (p>0.05). As a result, there was no connection between pregnancy rates and AMH levels after seeds in cows and cows. It has been a remarkable conclusion that variations in the levels of AMH between individuals and cows are at a very high level. New research is needed to increase knowledge on this subject by revealing the levels of AMH and the relationship of fertility in cows.

Anti-Mullerian Hormone (AMH) concentrations and antral follicle numbers were positively related in cattle. Therefore, it can be used as a biomarker in determining the reserve of ovary, determination of oocyte quality, superovulation response, fertility, productive life. In this study, it was aimed to determine the relationship between serum AMH levels and fertility parameters in cows and heifers. A total of 44 heifers and 40 cows were used as materials in the study. The first insemination pregnancy rate in cows, the average number of insemination per pregnancy, pregnancy rates in groups in 200 days postpartum, open days were analyzed as fertility parameters. The first insemination pregnancy rates in heifers, and total pregnancy rates and average number of inseminations per pregnancy were compared. The lowest AMH level in the heifers and cows was 0.001 ng/ml and the highest level was 0.7 ng/ml in both groups. The mean AMH level in cows and heifers was 0.26 ± 0.17 and 0.21 ± 0.16 ng / ml±SD, respectively (p>0.05). No significant relationship were found between the mean AMH levels of the pregnant and non-pregnant cows and heifers that were inseminated after AMH measurements (p>0.05). As a result, there was no relationship between pregnancy rates and AMH levels after insemination in heifers and cows. A remarkable finding was that the variation in AMH levels among individuals in both cows and heifers was very high. In order to reveal the relationship between AMH levels and fertility in cows, it is necessary to increase the knowledge on this subject by making new researches.
