The squamous cell carcinoma (SCC) is a neoplasm that affect pets and production animals and it’s very common in tropical countries like Brazil; develops in sparsely pigmented, stratified squamous epithelium and in mucosal surfaces exposed Ultraviolet action. The SCC is quite infiltrative but rarely causes metastases. Its occurrence in the female reproductive tract is recognized in the literature on cattle breeds from Europe. This case was a female bovine, Nelore, adult, who was referred to the "Hospital Veterinário Luiz Quintiliano de Oliveira" with dark brown fluid leakage and putrid odor, associated with ulcerative growth of the vagina. Because the extent of injury, the animal was euthanized and taken to the necropsy, which was observed on board structure, ulcerated and pus in the vaginal floor, infiltrated into the pelvic cavity to the serosa of the uterine body. The microscopic findings were detected neoplastic proliferation of epithelial cells in the floor and vaginal metastases in the lung parenchyma, and classified the primary tumor and metastasis as squamous cell carcinoma moderately differentiated.

This study evaluated the relationship between Se supplementation and serum cortisol in repeatedly handled cattle. Sixty Nellore calves were randomly distributed into four experimental groups, which were fed a mineral-protein mixture added with Se to achieve individual daily supplementation of 0 (Gc), 3.6 (G3.6), 5.4 (G5.4) and 6.4 (G6.4) mg Se. Stressful handling procedures and blood sampling were performed on days 0, 15, 30, 60, 90 and 120. Serum cortisol increased until day 90 and decreased on day 120, irrespective of Se supplementation. This finding shows that cattle reached a stress state but adapted. Cortisol and Se levels were not markedly correlated. Serum Se increased over the course of the experiment in the supplemented groups. However, because serum Se decreased in Gc, it may have mobilized to form the selenoproteins needed to remove metabolic wastes from handling-related oxidative stress.
