Abstract:  RESUMOObjetivou-se descrever os achados ultrassonográficos nos testículos e epidídimos de carneiros jovens. Análises de desenvolvimento ponderal, mensurações das características biométricas testiculares e exames ultrassonográficos foram realizados dos 140 aos 280 dias de idade, a cada 28 dias. O parênquima testicular apresentou ecogenicidade homogênea (baixa a moderada) que aumentou com a idade. A ecogenicidade e a espessura do mediastino aumentaram com a idade, e a cauda do epidídimo apresentou aspecto hipo… Show more

“…These results were similar to those found by Gouletsou et al (2003), Amorim (2010), Andrade et al (2012), and Andrade et al (2014). Silva et al (2015) observed values lower than those found in pre-pubertal and pubertal groups, which were near 70.20 pixels (3 to 6 months old) and 91.44 pixels (7 to 12 months old) for crossbred sheep.…”

“…Although some authors have studied testicular echogenicity of healthy sheep (Amorim, 2010;Teixeira et al, 2011;Andrade et al, 2012;Urt, 2014), few have developed studies involving ultrasound biometry of the bulbourethral glands in Santa Ines sheep, especially in pre-pubertal, pubertal, and sexually mature animals and correlated biometrics with all the variables presented in this study.…”

“…Segundo Ahmad et al (1991) o exame ultrassonográfico é uma ferramenta útil no monitoramento de mudanças progressivas que ocorrem nos testículos. Andrade et al (2012) avaliando ultrassonograficamente testículos de carneiros mestiços, verificaram PT de baixa ecogenicidade até os 140 dias de idade, com aumento identificado a partir de 168 dias. Os mesmos autores também encontraram uma fase em que a ecogenicidade testicular diminuiu, atribuindo este fato a formação do lúmen dos túbulos seminíferos, término da formação das células de Sertoli, e consequente, produção de fluido por estas célu-las, necessários a espermatogênese.…”

“…Andrade et al [10] FSLT = fibrosis score of the left testicle; CONS = consistency; TURB = turbulence; MOT = straight-line progressive spermatic motility; VIG = spermatic vigor; MDEF = major defects; MINDEF = minor defects; TDEF = total defects. **Correlation is significant at a level of 0.01.…”
