Abstract: The objective of this study was to explore the population characteristics and influencing factors of plasma anti-Müllerian hormone (AMH) concentration in Holstein cows, and to estimate its genetic parameters. A total of 625 blood samples were collected from 398 healthy Hols-tein cattle in a large-scale dairy farm in Beijing. The plasma AMH concentration was determined by ELISA method. The MIXED procedure in SAS 9.2 was used to analyze the influencing factors of the plasma AMH concentration. A single trait animal model was used to estimate the variance components and genetic parameters of the plasma AMH concentration and the approximately genetic correlations between the plasma AMH concentration and some reproductive traits were calculated by DMU. The results from this study showed that the mean of the plasma AMH concentration in Holstein cattle was (96.30±14.25) ng·L-1. The plasma AMH concentration was significantly (P<0.01) influenced by the sampling season, and was not significantly influenced by the parity, pregnant stage and lactation stage. The plasma AMH concentration was a moderately heritable trait with a heritability of (0.10±0.08). The plasma AMH concentration was associated with the interval from calving to the first service, interval from the first to the last inseminations and stillbirth in heifer and cow with moderate to high genetic correlations and approximate genetic correlation coefficients ranging from 0.3 to 0.7. In conclusion, this study provided a reference for further research on the genetic basis of the plasma AMH concentration in Holstein cattle, which was helpful to investigate the reproductive performance of dairy cows by AMH concentration.
