Timpanismo ruminal crônico secundário à hipoplasia de pregas de omaso em dois bovinos / Chronic ruminal bloat secondary to omasal laminae hypoplasia in two cattle

Um novilho normando e outro charolês apresentando distensão abdominal, diarreia intermitente e timpanismo ruminal crônico, que iniciaram após desmame, foram enviados para necropsia. Observou-se ausência de pregas omasais associada à hipoplasia do órgão, assim como redução de tamanho das papilas ruminais e reticulares.

Hyperthermia, skin alopecia and pruritus were the main clinical signs. Macroscopically, gray to white up to 5cm nodules were detected, especially in kidney and lymph nodes, which correspond to mild to severe multifocal granulomatous infiltrate.
