Hemodynamic evaluation of the supratesticular artery in bulls

摘要: Abstract The evaluation of testicular hemodynamics can contribute significantly to understanding the thermoregulatory mechanisms and supply oxygen in testis domestic animals. aim this study was evaluate used Color Doppler ultrasonography bulls Aberdeen Angus Polled Hereford breeds at four different moments (C1, C2, C3 C4) during seasonal variations bovine breeding Twenty-eight (Polled n = 12 n = 16) were evaluated by means velocimetry (MV), pulsatility index (PI) resistance (RI) using ultrasonography. climate temperature humidity (THI) data collected from an automatic meteorological station National Institute Meteorology. Data analyzed ANOVA Tukey's test Pearson's correlation with significance level 5% used. Preliminary analyses showed no differences within breeds, or interaction breed collection. However, significate difference observed when time collection evaluated. MV blood flow (cm/s) (7.53 ± 2.66) compared C4, C1 C2 (13.63 ± 4.24, 13.57 ± 4.32 10.97 ± 3.37, respectively; P
