For this purpose, thirty-six non-lactating purebred Arabian mares with no previous fertility problems constituted the material of the study. The animals were assigned to groups according to their age: Group I (aged 4-8 years), group II (9-18 years) and group III (19-25 years). Mean serum AMH concentrations were significantly higher (P<0.001) in group II (0.873±0.096 ng/mL) than in groups I (0.466±0.051 ng/mL) and III (0.347±0.068 ng/mL). Furthermore, serum AMH concentration was positively correlated with the daily increase in ovarian follicle diameter as well with mares with higher conception rates. It was also negatively correlated with anovulation and number of mating per conception. In summary, a strong relationship was found between peripheral AMH concentrations and fertility performance in purebred Arabian mares.
