Follicular thyroid carcinoma in dogs. Report of cases

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 foully 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.

Productive and reproductive performance of heifers fed different levels of urea in the diet

The objective of the present study was to evaluate the nutrient intake, blood parameters, follicular diameter and performance of pre-puberty crossbred heifers fed isoproteic diets (14.1%CP) containing 0.0; 0.44; 0.88 and 1.32% urea on the total dry matter (DM) of the diet, with a 77:23 roughage:concentrate ratio. Twenty-four 18- month old heifers (Holstein x Zebu), 277.9 kg mean live weight (LW) were used, distributed in four treatments and six replications in a randomized complete design. The following were evaluated: dry matter intake (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE), hemicellulose (HEM), plasmatic ureic nitrogen (PUN), plasmatic glucose, plasmatic total cholesterol, follicular diameter and daily weight gain (DWG). No influence of the urea levels in the diet was observed on NDF and HEM intake. A maximum intake was obtained of DM (8.75 kg day(-1)), CP (0.88 kg day(-1)), ADF (2.5 kg day(-1)) and EE (0.17 kg day(-1)) respectively for the levels 0.7, 0.8, 0.7 and 0.7% urea in total DM. The 0.6%; 0.77% and 0.6% urea levels in diet were the critical points for obtaining maximum response for the PUN (10.96 mg dL(-1)) and plasmatic glucose (84.97 mg dL(-1)) concentrations and, for follicular diameter (11.08 mm) on the 40(th); 24(th) and 31(st) day, respectively. The plasmatic total cholesterol concentration and DWG were not influenced by the urea added to the diet, with averages of 119.39 mg dL(-1) and 1.66 kg day(-1), respectively. It was concluded that urea can be added up to 1.32% on the total DM of the diet for pre-puberty crossbred heifers.

Características anátomo-estruturais da pelé de ovinos (ovis áries L.) lanados e deslanados, relacionadas com o aspecto físico-mecânico do couro

The objective of the study was establishing the anatomical-structural differences between the skin of non-wool sheep of the Morada Nova breed and wool-on sheep of the Polwarth or Ideal breeds and their relations to the physical-mechanical characteristics of their leather after tanning. Ten animals of both breeds were used, with five animals of approximately one and four years of age of each breed. The animals were slaughtered, and immediately after skinning, samples were taken viewing the microtomy of the skin in the dorsal, lateral, ventral, hind and palette regions, parallel and perpendicular to the head-tail axle, and perpendicular to the grain of the skin. The skins were depilated, chromium-tanned and re-tanned. From the leather, three samples were taken from the two directions considered from the regions studied for physical-mechanical analysis, for tension and tear resistance and distension on the lastometer. The average of the results of the physical-mechanical analysis were compared by Tukey test at the levels of 1 and 5% probability. The breed, the age, the region and the position exerted a positive effect on the values of the resistance of the leather to tension for the Morada Nova four year old sheep, reaching a minimum of 200 kg/cm . The region and the position exerted a positive effect on the values of tear-resistence of the leather for both breeds studied, reaching a minimum of 40 kg/cm. The resistance of the leather on distension was superior to 8 mm, for all the animals studied, not influenced by breed, age, region or position. The skin of the Ideal sheep presented a thermostatic skin layer greater than the reticular layer with great folicular and glandular density, contrary to the skin of the Morada Nova sheep where the thermostatic and reticular layers are of approximately the same thickness, with less folicular and glandular density.
