Abstract

Objective: This study was to evaluate the relationship between serum anti-Müllerian hormone (AMH) concentration and antral follicle count (AFC) during the estrous cycle of Colombian Creole cows of the Chino Santandereano breed.

Materials and methods: Ten non-lactating, non-pregnant, multiparous cows of the Chino Santandereano breed (Bos taurus taurus adapted), aged between 3 and 7 years, with a body condition of 3.0 ± 0.4 and with normal reproductive tracts at the structural and functional level, were selected and used. For the synchronization of estrus and ovulation, an intravaginal progesterone release device plus 2 mg of estradiol benzoate was applied for 8 days. On day 8, 150 μg of cloprostenol sodium + 300 IU of equine chorionic gonadotropin + 1 mg of estradiol cypionate was administered. This protocol was performed to determine the antral follicular count and to quantify serum AMH levels every 5 days during the estrous cycle.

Results: The mean serum AMH concentration and AFC were 725 ± 2.7 pg/ml and 43.4 ± 3.5, respectively. A high correlation was observed between AMH and AFC of r = 0.041; p < 0.0001.

Conclusion: The results showed that in Creole cows of the Chino Santandereano breed, there is a high correlation between circulating levels of AMH and ovarian reserve. This mechanism can be used as an endocrine biomarker of the follicular population.

哥伦比亚克里奥尔奶牛抗勒勒菌激素浓度与窦卵泡数的关系。

目的：研究哥伦比亚克里奥尔奶牛发情周期中血清抗勒氏激素（AMH）浓度与窦卵泡计数（AFC）的关系。材料与方法：选择3 ~ 7岁、体况3.0±0.4、生殖道结构与功能水平正常的Chino Santandereano品种未泌乳、未妊娠、已产奶牛10头（适用于Bos taurus）。为了同步发情和排卵，阴道内孕酮释放器加雌二醇2 mg苯甲酸酯应用8天。第8天，给予氯前列醇钠150 μg +马绒毛膜促性腺激素300 IU +雌二醇1 mg。在发情周期中，每5天进行一次胃窦卵泡计数和定量血清AMH水平的测定。结果：血清AMH平均浓度为725±2.7 pg/ml， AFC平均浓度为43.4±3.5 pg/ml。AMH与AFC呈高度相关（r = 0.041）；P < 0.0001。结论：在Chino Santandereano品种的克里奥尔奶牛中，循环AMH水平与卵巢储备有高度相关性。该机制可作为卵泡群的内分泌生物标志物。
