Higher body fatness adversely affects metabolic and hormonal homeostasis. The present work aimed to evaluate the association between body condition score (BCS) and haemodynamic pattern and echogenic appearence of the testes as well as nitric oxide (NO) levels and total antioxidant capacity (TAC). For that, fifteen Ossimi rams were blocked according to their BCS into a lower BCS group (L-BCS:2–2.5; n = 5), medium BCS group (M-BCS:3–3.5; n = 5), and higher BCS group (H-BCS:4–4.5; n = 5). Rams were examined for testicular haemodynamics (TH; Doppler ultrasonography), testicular echotexture (TE; B-mode image software analysis), and serum levels of NO and TAC (colorimetric). Results are presented as means ± standard error of the mean. There was a significant (P < 0.05) difference in the resistive index and pulsatility index means among the groups under experimentation, being the least in the L-BCS group (0.43 ± 0.02 and 0.57 ± 0.04, respectively) compared to the M-BCS (0.53 ± 0.03 and 0.77 ± 0.03, respectively) and H-BCS rams (0.57 ± 0.01 and 0.86 ± 0.03, respectively). Among blood flow velocity measurements [peak systolic, end-diastolic (EDV), and time-average maximum], only EDV showed significant (P < 0.05) higher values in the L-BCS group (17.06 ± 1.03 cm/s) compared to M-BCS (12.58 ± 0.67 cm/s) and H-BCS (12.51 ± 0.61 cm/s) groups. Regarding the TE results, there were no significant differences among the examined groups. There were significant differences (P < 0.01) in the concentrations of TAC and NO among the groups under experimentation, in which the L-BCS rams had the highest levels of TAC and NO in their sera (0.90 ± 0.05 mM/L and 62.06 ± 2.72 μM/L, respectively) than the M-BCS (0.058 ± 0.05 mM/L and 47.89 ± 1.49 μM/L, respectively) and H-BCS rams (0.45 ± 0.03 mM/L and 49.93 ± 3.63 μM/L, respectively). In conclusion, body condition score is associated with both testicular hemodynamic and the antioxidant capacity in rams.

公羊身体状况评分、睾丸血流动力学和回声性、一氧化氮水平和总抗氧化能力之间的关联

较高的身体脂肪会对代谢和荷尔蒙稳态产生不利影响。目前的工作旨在评估身体状况评分 (BCS) 与血液动力学模式和睾丸回声外观以及​​一氧化氮 (NO) 水平和总抗氧化能力 (TAC) 之间的关联。为此，十五只 Ossimi 公羊根据其 BCS 分为较低 BCS 组（L-BCS：2-2.5；n = 5）、中等 BCS 组（M-BCS：3-3.5；n​​ = 5）和更高BCS 组（H-BCS：4–4.5；n = 5）。检查公羊的睾丸血流动力学（TH；多普勒超声）、睾丸回声纹理（TE；B 模式图像软件分析）以及 NO 和 TAC 的血清水平（比色法）。结果表示为平均值±平均值的标准误差。具有显着性（P < 0. 05) 实验组间阻力指数和搏动指数平均值的差异，与 M-BCS（0.53 ± 0.03 和 0.77 ± 0.03，分别）和 H-BCS 公羊（分别为 0.57 ± 0.01 和 0.86 ± 0.03）。在血流速度测量 [峰值收缩、舒张末期 (EDV) 和时间平均最大值] 中，只有 EDV 在 L-BCS 组 (17.06 ± 1.03 cm/s) 中显示出显着 (P < 0.05) 更高的值M-BCS (12.58 ± 0.67 cm/s) 和 H-BCS (12.51 ± 0.61 cm/s) 组。关于 TE 结果，检查组之间没有显着差异。实验组间TAC和NO浓度存在显着差异(P < 0.01)，其中 L-BCS 公羊的血清中 TAC 和 NO 水平最高（分别为 0.90 ± 0.05 mM/L 和 62.06 ± 2.72 μM/L），高于 M-BCS（0.058 ± 0.05 mM/L 和 47.89 ±分别为 1.49 μM/L）和 H-BCS 公羊（分别为 0.45 ± 0.03 mM/L 和 49.93 ± 3.63 μM/L）。总之，身体状况评分与公羊的睾丸血流动力学和抗氧化能力有关。
