Ultrasonographic evaluation of testicular and Pampiniform plexus characteristics in young bulls under different microclimatic conditions in a tropical environment.

ABSTRACT: This study aimed to evaluate the ultrasonographic characteristics of the testicles and pampiniform plexus of young bulls from 8 to 19 months of age under different microclimatic conditions. For this, 46 animals (8.0 ± 0.5 months and 211.0 ± 5.9 kg) were raised in two intensive rotational systems for 12 months, in which 24 animals (Nelore, n = 12; Canchim, n = 12) in a silvopastoral system and 22 animals (Nelore, n = 10; Canchim, n = 12) in a non-shaded pastoral system. Testicular biometric measurements, B-mode ultrasound assessments (echogenicity and heterogeneity of the testicular parenchyma and mediastinum), color Doppler (blood perfusion of the testicular parenchyma and pampiniform plexus), spectral Doppler of the supratesticular artery (pulsatility and resistance index), and blood coll
