*AMH levels were classified as L, M and H based on the 25th and 75th percentile values of plasma AMH concentration in Fig. 1A. Different uppercase letters represent statistical differences among anti-Müllerian hormone (AMH) levels in each farm. Different lowercase letters represent statistical differences among farms at each AMH level.
