Resumo
In recent years, egg production has had an intense growth in Brazil, and Brazilian egg consumption per capita has significantly increased in the last decade. To reduce sanitary and financial risks, decisions regarding the production and health status of the flock must be made based on objective criteria. Our aim was to determine the main "input" variables for the prediction of egg production performance in commercial laying breeder flocks using an ANN model. The software NeuroShellClassifier and NeuroShell Predictor were used to build the ANN. A total of 26 egg-production traits were selected as input variables and eight as output variables. A database of 44,120 Excel cells was generated. For the training and validation of the models, 74.9% and 25.1% of the data were used, respectively. The accuracy of the ANN models was calculated and compared using the analysis of coefficient of multiple determination (R2), mean squared error (MSE), and an assessment of uniform scatter in the residual plots. The models for the outputs "weekly egg production," "weekly incubated egg,", "accumulated commercial egg," and "viability" showed an R2 greater than 0.8. Other models yielded R2 values lower than 0.8. The ANN predicts adequately eight egg-production traits in the breeders of commercial laying hens. The method is an option for data management analysis in the egg industry, providing estimates of the relative contribution of each input variable to the outputs.(AU)

Um cão SRD, com cinco anos e histórico de ascite de evolução lenta com estruturas palpáveis foi submetido a exames clínicos, os quais foram inconclusivos. A laparotomia exploratória revelou que a cavidade abdominal estava repleta de líquido serossanguinolento e de múltiplos nódulos de diferentes tamanhos, com superfície irregular, aderidos aos peritônios visceral e parietal, sugestivos de neoplasia maligna. A eutanásia, seguida da necropsia para a coleta de amostras para o diagnóstico histopatológico, foi indicada. O exame anatomopatológico revelou nódulos sésseis e resistentes ao corte, constituídos de tecido conjuntivo fibroso e trabéculas ósseas em arranjo de osso esponjoso e osteoclastos em atividade. O diagnóstico definitivo foi peritonite encapsulante esclerosante.(AU)
A 5-year-old dog with chronic ascites was submitted to several clinical exams, which were inconclusive. Laparotomy revealed abdominal serosanguinous fluid and multiple nodules of several sizes with irregular surface, with visceral and parietal adhesion to the peritoneum, resembling malignant neoplasia. Euthanasia followed by necropsy and collection of samples to histopathological diagnosis was performed. Pathological exam revealed sessile nodules resistant to cut and the microscopy evaluation showed fibrous connective tissue and trabecular bone with sponge bone arrangement associated with active osteoclasts. The definitive diagnosis was sclerosing encapsulating peritonitis.(AU)

Um leitão oriundo de um criatório do norte do estado do Rio de Janeiro, mantido no biotério do Hospital Veterinário da Universidade Estadual do Norte Fluminense Darcy Ribeiro e utilizado como caso piloto de projeto de pesquisa para investigações sobre o acesso videolaparoscópico retal (NOTES - Natural Orifice Translumenal Endoscopic Surgery), foi eutanasiado e necropsiado. Amostras do ponto de acesso do tubo de inserção na região mucocutânea anal foram colhidas, fixadas em formalina neutra tamponada a 10%, processadas por inclusão em parafina e coradas pela hematoxilina e eosina para histologia. Observou-se o comprometimento de folículos que, dilatados, exibiam formações que lembravam Demodex spp. cortados em vários sentidos e, por se tratar de ácaros espécie-específicos, concluiu-se como D. phylloides. Na citopatologia, o ácaro foi recuperado e identificado a fresco, mostrando-se alongado, com quatro pares de patas ventrais e no terço anterior do corpo. Este se refere ao primeiro registro de demodicose suína no estado do Rio de Janeiro.(AU)
A piglet derived from a farm in northern Rio de Janeiro State, maintained at the Animal Veterinary Hospital of Universidade Estadual do Norte Fluminense Darcy Ribeiro and used as a pilot case for a research project on access to research video-laparoscopic rectal (NOTES - Natural Orifice Endoscopic Surgery Translumenal) was euthanized and necropsied. Samples from the access point of the insertion tube in mucocutaneous anal region were collected, fixed in buffered formalin 10%, processed by embedding in paraffin and stained with hematoxylin and eosin for histopathology. The impairment of follicles that exhibited dilated formations resembling Demodex spp. cut in various directions and due to the mite species-specific was observed, and was concluded as D. phylloides. The mite was recovered and freshly identified by cytopathology. It was elongated, with four pairs of legs, at ventral and anterior third of the body. This refers to the first report of swine demodicosis in Rio de Janeiro State.(AU)
