The aim of this study was to report the occurrence of two cases of thyroid neoplasm in dogs. The treatment of choice for these cases was surgical removal. In both cases the diagnostic was infiltrative follicular carcinoma of thyroid. The first animal did not present a good recovery after the surgery, and died four hours after the procedure. In the second case, the diagnosis was more precocious and antineoplastic chemotherapy was used after the surgery. At the time of submission of this manuscript, this animal had survived for fourty months. Currently, there is a need to define the protocols of chemotherapy to avoid relapse and metastases, in order to increase the life expectancy in dogs with thyroid neoplasm. &nbsp, El presente trabajo tiene como objetivo relatar la ocurrencia de dos casos de neoplasia de tiroides en perros. El tratamiento de elección para estos casos fue exéresis quirúrgica. En ambos casos el diagnóstico fue carcinoma folicular infiltrativo de tiroides. El primer animal no presentó buena recuperación posquirúrgica, y murió cuatro horas después del término de la cirugía. En el segundo caso el diagnóstico fue más precoz y después de la cirugía se asoció el uso de la quimioterapia antineoplásica. Hasta el momento, este animal presenta cuarenta meses de supervivencia. Actualmente, existe la necesidad de definir protocolos quimioterapéuticos más eficaces para evitar la ocurrencia de recidivas y metástasis, aumentando la expectativa de vida de los perros con neoplasia tiroidea. &nbsp

Twenty experimental silos made of PVC pipe (100 x 340 mm), in a completely randomized design with 5 levels of addition (0; 5; 10; 15; and 20%) of MB and 4 replications. Upon 32 days of ensilage, samples were collected for determination of levels of dry Matter (DM), crude protein (CP), ethereal extract (EE), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicelluloses (HC), ammonia nitrogen (N-NH3), and pH values. Data were evaluated by analyses of variance and regression analyses using the F test at the 5% level. The levels of DM and CP increased of 0.50 and 0.03 percentage units, respectively, for every 1% of MB added. The levels of NDF and ADF decreased of 0.51 and 0.24 percentage units, respectively, for every 1% of MB added. The levels of N-NH3 decreased from 4 to 23 percentage units while pH values remained constant (p>0.05), with average values of 3.29. Addition of 20% of MB improved silages chemical composition by promoting an increase in the levels of MS and reduction in the levels of fiber.
