摘要: 为探究荷斯坦牛血浆抗缪勒氏管激素(anti-Müllerian hormone,AMH)浓度的群体特征和影响因素,并初步估计其遗传参数,本研究采集了北京地区某规模化牛场398头健康泌乳母牛共625份血样,采用ELISA酶免法测定血浆AMH浓度,利用SAS 9.2软件的MIXED过程建立模型,分析血浆AMH浓度的影响因素;此外,基于DMU软件使用单性状动物模型对血浆AMH浓度进行方差组分和遗传参数估计,并计算AMH与奶牛部分繁殖性状之间的近似遗传相关。结果表明,北京地区荷斯坦牛血浆AMH浓度为(96.30±14.25) ng·L-1;采样季节对血浆AMH浓度有极显著影响(P<0.01),胎次、妊娠天数以及泌乳天数对血浆AMH浓度均无显著影响;血浆AMH浓度属于中等遗传力性状,遗传力为(0.10±0.08);血浆AMH浓度与产犊后首次配种间隔、青年牛和经产牛的首末次配种间隔及死产率均存在中高遗传相关,近似遗传相关系数介于0.3~0.7之间。综上,本研究对AMH浓度的影响因素和遗传参数进行了初步分析,为进一步研究荷斯坦牛AMH浓度的遗传基础提供了参考,有助于通过AMH浓度对奶牛的繁殖性能进行研究。

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.
