Resumo: | The aim of this study was to evaluate the dynamics of the scrotal temperature, sperm quality and testicular blood flow by using infrared thermography and Doppler ultrasonography in bulls submitted to scrotal insulation. Braford bulls (n = 8) at 18 months of age, were assigned into the following groups: insulated for 72 h (G 72; n = 2), 96 h (G 96, n = 2), 120 h (G 120, n = 2), and control animals (CON; n = 2) that remained without insulation. Infrared thermography and Doppler ultrasonography parameters were measured at four different time points: immediately after the scrotal insulation (M0), within 10 min (M10), 30 min (M30) and 60 min (M60) after scrotal insulation. The sperm quality was evaluated weekly (S1/S12). The data were analyzed by ANOVA, t-test (paired) and Pearson's correlation with a significance level of 5%. None of the observed variables were different between the insulated groups (P > 0.05). Insulated animals showed higher scrotal temperature in M0 compared to that in the M10, M30 and M60 periods (P < 0.05). There was no difference in the pulsatility and resistive indexes after scrotal insulation. However, blood flow velocity was higher in M10 compared to that in the M0, M30 and M60 periods (P < 0.05). The sperm quality was higher (P < 0.05) in all twelve collections from the control group compared with the insulated groups. Scrotal insulation resulted in changes in the sperm quality, scrotal temperature and testicular blood flow velocity. |

Touros Braford (n=8) aos 18 meses de idade, foram distribuídos nos seguintes grupos: insulados por 72 h (G 72; n=2), 96 h (G 96; n=2), 120 h (G120, n=2), e animais controle (CON; n=2) que permaneceram sem insulação. Os parâmetros de termografia infravermelha e ultrassonografia Doppler foram medidos em quatro diferentes momentos: imediatamente após a insulação escrotal (M0), aos 10 min (M10), 30 min (M30) e 60 min (M60) após a insulação escrotal. A qualidade espermática foi avaliada semanalmente (S1 / S12). Os dados foram analisados por ANOVA, teste t (pareado) e correlação de Pearson com nível de significância de 5%. Nenhuma das variáveis observadas foi diferente entre os grupos insulados (P > 0,05). Os animais insulados apresentaram maior temperatura escrotal em M0 quando comparados aos M10, M30 e M60 (P < 0,05). Não houve diferença nos índices de pulsatilidade e resistividade após a insulação escrotal. No entanto, a velocidade do fluxo sanguíneo foi maior em M10 em relação aos períodos M0, M30 e M60 (P < 0,05). A qualidade espermática foi maior (P < 0,05) em todas as doze coletas do grupo controle em comparação com os grupos insulados. A insulação escrotal resultou em mudanças na qualidade espermática, temperatura escrotal e na velocidade do fluxo sanguíneo testicular.UEL2020-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionresearchapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3736210.5433/1679-0359.2020v41n4p1267Semina: Ciências Agrárias; Vol. 41 No. 4 (2020); 1267-1278Semina: Ciências Agrárias; v. 41 n. 4 (2020); 1267-12781679-03591676-546Xreponame:Semina.
