We evaluated the relationship between plasma anti-Müllerian hormone (AMH) concentrations in Japanese Black (JB) heifers at 7−10 months of age and the number of embryos recovered after superovulation treatment in selected ovum pick-up donors, concomitantly with changes in their AMH concentrations before and after parturition. Plasma AMH concentrations in heifers were positively correlated with the total number of follicles (r = 0.647, P < 0.01) and embryos (r = 0.681, P < 0.01) recovered from the animals postpartum, when selected as donor cows, but did not correlate with the total number of transferable embryos. No difference was observed between the plasma AMH concentration at the heifer period and the postpartum period. Additionally, serum AMH concentrations of heifers weakly correlated with the number of follicles and embryos recovered by virgin flush after superovulation treatment at 13−15 months of age. Therefore, a single blood AMH concentration measurement may accelerate intensive JB cattle breeding.

单一血液抗苗勒管激素 (AMH) 浓度测量在畜群育种计划中选择日本黑小母牛胚胎供体的功效

我们评估了 7-10 个月大日本黑 (JB) 小母牛的血浆抗苗勒管激素 (AMH) 浓度与选定的取卵供体的超排卵治疗后恢复的胚胎数量之间的关系，同时伴随着它们的变化。分娩前后的 AMH 浓度。当被选为供体奶牛时，小母牛的血浆 AMH 浓度与从动物产后回收的卵泡总数 (r = 0.647, P < 0.01) 和胚胎总数 (r = 0.681, P < 0.01) 呈正相关，但不相关可移植胚胎的总数。在小母牛时期和产后时期的血浆AMH浓度之间没有观察到差异。此外，小母牛的血清 AMH 浓度与在 13-15 个月大的超排卵治疗后通过处女冲洗恢复的卵泡和胚胎数量呈弱相关。因此，单次血液 AMH 浓度测量可能会加速 JB 牛的集约化养殖。
