CARDILLI, D.J. et al. Testicular ultrasonography in young Nelore bulls raised in extensive management system. Arq. Bras. Med. Vet. Zootec. [online]. 2012, vol.64, n.1, pp. 75-82. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352012000100012.
The aim of this study was to evaluate the testicular parenchyma of young Nelore bulls through standard ultrasound, in order to establish the physiological standards, as well as differences in echogenicity between pre-pubescent and pubescent animals of the same age. Testis of 19 young Nelore bulls were evaluated by ultrasonography at 10, 12, 14, 16 and 18 months old. Homogeneous and moderate testicular parenchyma echogenicity was observed in all animals. Testicular echogenicity increased with the age of the animal. There were no significant differences in testicular echogenicity between pre-pubescent and pubescent animals with the same age.
