Abstract

ABSTRACT This study aimed to evaluate the relationship between the antral follicle count (AFC) and the ovarian morphology of Bos indicus in different age groups: 12-23 months (G1), 24-35 months (G2), 36-47 months (G3), 48-59 months (G4), and >60 months (G5). Ovaries were collected individually and sent to the laboratory, where we measured AFC, the diameter and weight of the ovaries, dominant follicle (DF, ≥8mm), corpus luteum (CL), and small follicles (SF, <8mm). AFC were classified as high, intermediate-high, intermediate-low, and low. A group of ovaries was subjected to follicular aspiration to evaluate the morphological quality of the recovered cumulus oocyte complexes (COCs). Mean AFC did not vary between ages. The morphological characteristic that was most closely correlated with AFC was the weight of the small follicles. There was no relationship between AFC and the weight and diameter of the DF and CL. Quality of the COCs was superior in ovaries in which the CL was present, but it did not vary between the AFC classes. We conclude that AFC can be performed on a single ovary, regardless of the presence, diameter, and weight of the CL and DF in zebu between 12 and 60 months old.

不同年龄籼稻卵泡数与卵巢形态的关系

摘要本研究旨在评估不同年龄组（12-23个月（G1）、24-35个月（G2）、36-47个月（G3）、48-59个月（G4）和>60个月（G5））的印度博斯窦卵泡计数（AFC）与卵巢形态之间的关系。单独收集卵巢并送往实验室，在那里我们测量AFC、卵巢的直径和重量、优势卵泡（DF，≥8mm）、黄体（CL）和小卵泡（SF，<8mm）。AFC分为高、中高、中低和低。对一组卵巢进行卵泡抽吸，以评估回收的卵丘-卵母细胞复合体（COCs）的形态质量。平均AFC在不同年龄段之间没有变化。与AFC最密切相关的形态学特征是小卵泡的重量。AFC与DF和CL的重量和直径之间没有关系。存在CL的卵巢的COCs质量较高，但AFC级别之间没有差异。我们得出的结论是，在12至60个月大的zebu中，无论CL和DF的存在、直径和重量如何，AFC都可以在单个卵巢上进行。
