Abstract

Ultrasonographic characterization of testicles of Quarter Horse stallions bred in the State of Paraíba. The study aimed to characterize, by means of ultrasound, the normal range on the testicular parenchyma echogenicity and echogenicity and echotexture in 24 stallions Quarter horses of different ages. The animals were divided into two groups according to the age. First this formed by animals up to 4 years old and the second with animals over the age of 4 years. Originate from semi-arid region of Paraiba in the towns of Patos, Santa Terezinha and Boa Vista. We used an ultrasound machine and brand Chisson D600 Vet linear transducer of 5 MHz frequency. We confirm the hypoechoic testicular parenchyma echogenicity of moderate intensity in 35 (73%) and low intensity in 13 (27%) images, presented homogeneous echotexture in 34 (71%) and heterogeneous in 14 (29%).The testicular echogenicity was not affected by age and the percentage that expresses the variations in gray scale confirmed the clinical classification of echogenicity of low or moderate.
