- 요약Anti-Mullerian hormone (AMH) has emerged as a potential biomarker for super-ovulatory response ovarian reserve and reproductive performance in dairy cattle, yet its association with fertility traits and reproductive outcomes remains unclear. Moreover, inhibin A and B are gonadal hormones involved in the regulation of FSH and folliculogenesis; however, their association with reproductive physiology and fertility traits in dairy cattle remains largely unexplored. Furthermore, the relationship between AMH and inhibin A & B, as potential biomarkers for reproductive performance, and its association with GDPR has yet to be investigated. The objectives of this study were to evaluate the association of plasma concentration of AMH and inhibin A and B at the first gonadotropin-releasing hormone (G1) and prostaglandin F2α (PGF) of breeding Ovsynch of a Double-Ovsynch (DO) protocol with genomic prediction of daughter pregnancy rate (GDPR), ovulation at G1, and pregnancy per artificial insemination(P/AI). Lactating Holstein cows (n = 519) with data available for GDPR, ovarian dynamics at G1, PGF, and P/AI were used to investigate associations of AMH, GDPR, and pregnancy outcomes. At G1 and PGF, cows had their ovaries scanned by ultrasonography for characterization of ovarian structures, and blood samples were collected for assessment of AMH, inhibin-A, inhibin-B and progesterone (P4) concentrations. Univariate analyses were performed to explore the relationship among these hormones and parity, lactation number, body condition score (BCS) at G1 and PGF, GDPR at G1 and PGF, presence of corpus luteum (CL) 14mm, diameter of CL, presence of multiple CL, total luteal volume, presence of large antral follicles 10mm, diameter of the largest follicle, presence of multiple follicles, follicular volume, number of follicles, number CL, plasma P4 concentration, ovulation at G1, and P/AI. Multivariable logistic regression was used to assess the relationship of AMH with ovulation at G1, P/AI, and other variables associated with these responses. Also, receiver operating characteristics (ROC) were performed to assess whether AMH concentrations could predict ovulation at G1 and P/AI. Concentrations of AMH at days -10 and -3 were moderately correlated (r = 0.76). Multiparous cows had greater AMH concentration than primiparous cows. Cows in their 2nd and 3rd lactations had greater AMH concentrations than those in their 1st lactation. The AMH concentrations were weakly correlated with GDPR at G1 (r = 0.05) and PGF (r = 0.12). Cows were categorized according to GDPR, and there was a quadratic relationship between AMH concentration and GDPR quartile. The presence of multiple antral follicles was negatively associated with AMH concentration at the PGF, but not at G1. The number of follicles 10 mm tended to be associated with higher AMH concentration at both time points. Neither the size of the largest follicle nor the total follicular volume was associated with AMH at G1 and PGF. The presence of multiple CLs was not associated with AMH, and the total luteal volume was positively associated with high AMH concentrations at G1 and PGF. The AMH concentration was not associated with P4 concentration at G1 and PGF. The AMH concentration was greater in cows that ovulated than in cows that failed to ovulate, but AMH was not associated with ovulation and P/AI. The ROC analysis indicates that AMH concentrations could not predict ovulation at G1 or P/AI. For the inhibin A and B results, the concentration of inhibin A and inhibin B were moderately correlated between the two time points of the DO, the G1, and PGF (r = 0.64 and 0.73, respectively), while correlations between the two hormones at any time point remained low (r = 0.14 and 0.19, respectively). For luteal parameters, there were correlations only between Inhibin A and the largest CL at PGF (r = -0.11) and total volume at PGF (r = -0.11). In contrast, luteal parameters at G1 were not correlated with inhibin B had no correlations. For follicular parameters, there were no correlations for either Inhibin A or Inhibin B. For hormonal concentrations, there was a tendency for a correlation (r = -0.08) between P4 and Inhibin A at G1, but Inhibin A at PGF and P4 and Inhibin B at G1 and PGF were not correlated. When Inhibin concentrations were categorized, cows in the High Inhibin A group had a greater number of follicles than cows in the low Inhibin A group at G1. Moreover, cows in the High Inhibin A group had a smaller size for the largest CL than cows in the low Inhibin A group at G1. Greater inhibin A concentrations at PGF were observed in multiparous cows. For GDPR, there was only a tendency for a correlation between inhibin A and GDPR at PGF. When categorized, cows in the High Inhibin A at PGF had greater GDPR than cows in the Low Inhibin A group. In a multivariable regression model for ovulation, cows in the High Inhibin A and Medium Inhibin A groups at G1 ovulate more than cows in the Low Inhibin A group. In our univariate analysis, Inhibin B at G1 was greater in non-pregnant cows than in pregnant cows, but the multivariable logistic regression models showed that neither inhibin A nor B were associated with P/AI. The ROC analysis indicates that inhibin A and B concentrations could predict ovulation at G1 or P/AI. In conclusion, AMH concentration was positively associated with lactation number and had a weak, quadratic relationship with GDPR quartiles, but was not associated with ovulation at G1 or pregnancy per timed AI. Inhibin A and B were modestly associated with reproductive outcomes, but their predictive utility for ovulation and pregnancy per AI was limited.
