“…All sheep presented clinical signs similar to those described in the literature for goiter, which basically consisted of an increase in the palpable volume of the cranial ventral cervical region ( Figures 1A and 1B) (Ozmen et al, 2005;Campbell et al, 2012;Hassan et al, 2013). Panziera et al (2014), found, in addition to the accentuated symmetrical volume in the lobes of the thyroid gland, diffuse alopecia and a marked increase in symmetrical volume in the lobes of the thyroid gland, a clinical sign that was not registered in the animals of the current study. Hassan et al (2013), did not observe alopecia, however, they registered that the hair was rough, in addition to which, during auscultation and palpation of the neck area, the authors observed the presence of pulsation.…”

“…In some regions of Brazil, iodine deficiency has been reported over various decades, such as by Martins (1946), who diagnosed stillborn goats with congenital goiter due to maternal iodine deficiency in São Paulo and Megale (1949), who identified congenital goiter in calves, in Minas Gerais State. The most recent works are reported by Almeida et al (2013), who recorded cases in goats in São Paulo state, Panziera et al, (2014), who also recorded congenital goiter in goats in the northwest of Rio Grande do Sul and Martins et al, (2018) with cattle in the Center-South region of Mato Grosso. According to Riet-Correa (2007), the occurrence is more frequent in areas that are far from the sea and where rainfall is low.…”

“…No Brasil o bócio é, na maior parte das vezes, derivado da deficiência nutricional de iodo (Martins 1946, Tokarnia et al 2000, Panziera et al 2014. As doenças decorrentes das deficiências minerais em ruminantes estão relacionadas com a área geográfica, com a qualidade das pastagens e com a ausência de suplementação mineral.…”

“…Os sinais clínicos e os achados macroscópicos encontrados nos casos apresentados são semelhantes aos observados em outras descrições de bócio por deficiência de iodo em bovinos (Wither 1997, Tokarnia et al 2000 bem como em caprinos (Martins 1946, Panziera et al 2014, ovinos (Campbell et al 2012) e seres humanos (Pezzuti et al 2009). Em bezerros, o aumento bilateral difuso da tireoide é considerado o principal indicador do hipotireoidismo congênito (Stukovsky et al 1961, Wither 1997.…”
