Resumo. O testículo é um órgão que possui função exócrina, relacionada com a produção, armazenamento e transporte de espermatozoides, e função endócrina relacionada com a produção de hormônios andrógenos. Na busca por bons reprodutores tem sido avaliado características morfometrias testiculares como a circunferência escrotal, no entanto, somente a mesma não é suficiente para realizar uma seleção, utilizando-se assim de outros parâmetros como volume e comprimento testicular. Tendo isso em vista, o objetivo desta revisão é abordar a influência dos fatores biométricos e sua relação com a morfologia testicular e a qualidade seminal, para a avaliação de reprodutores.

The objective of the present study was to evaluate the clinical and laboratory alterations and hepatic lesions caused by the intake of Crotalaria spectabilis in sheep. Fifteen ewes (unknown breed) were used, which were allocated into three groups of 5 animals. These groups received milled C. spectabilis seeds in their feed over 28 days, with inclusion rates of 0.4% (G1), 0.6% (G2) and 1% (G3). Blood samples and hepatic biopsies for histology were drawn at: T0 (day before the seeds were included in the diet), T1 (7 days after the seeds were included), T2 (14 days), T3 (21 days) and T4 (28 days). The results were submitted to variance analysis (ANOVA) using Statistical Analysis System software (SAS), and differences between the means were compared by the Tukey posttest (p < 0.05). Only one animal from G3 presented clinical signs of intoxication at T3. The results from the hematological parameters were within the normal range for this species. Serum activity of aspartate aminotransferase (AST) and creatine phosphokinase(CK) did not show significant differences among the groups, whereas gamma-glutamyltransferase (GGT) activity was significantly different between G1 (33.66 ± 25.8 U/L) and G2 (67.3 ± 14.8 U/L) at T0. Ultrasonography evaluationrevealed hepatic alterations throughout the experimental period, which was confirmed by histology. Therefore, analyses of hemogram and hepatic function alone do not have diagnostic value for C. spectabillis intoxication in sheep, and it is necessary to perform additional tests, such as ultrasonography and percutaneous liver biopsies.

In December 2019, the world watched in disbelief as a viral epidemic, originating in Wuhan, Hubei Province, China, took on frightening proportions. On January 30, 2020, the World Health Organization (WHO) declared the outbreak of the disease caused by the new coronavirus (SARS-CoV-2) to be a public health emergency of international importance, the highest level of alert of the Organization, as provided in the International Health Regulations (IHR, 2016). On March 11, 2020, the epidemic was declared a pandemic by the WHO. Despite the rapid distribution of the new virus, many countries were reluctant or slow to comply strictly with the prophylactic methods suggested by those who had already experienced the whole situation of threat to the health of their populations.
