La región Puno, Perú, se viene convirtiendo en una importante zona de producción de leche y derivados lácteos, especialmente queso. Sin embargo, no se han realizado estimaciones de la estructura de la estructura de costos, ni la rentabilidad. Con la finalidad de desentrañar las inquietudes señaladas se ha efectuado el presente trabajo de investigación, teniendo como objetivo determinar la estructura de costos y la rentabilidad en la producción de queso en empresas tipo I y tipo II del distrito de Azángaro. Para tal efecto se recopilaron datos relacionados a la producción mediante la aplicación de una encuesta y la observación de 11 empresas, durante el mes de abril del 2015. Para el procesamiento de datos se utilizó Excel 2010 y se tuvieron los siguientes resultados: Los costos variables en las empresas tipo I y tipo II productoras de queso alcanzaron cifras de 90.40% y 95.8...

Squamous cell carcinoma (SCC) is a malignant neoplastic disease that affects various animal species in many parts of the world causing economic losses of varying degrees. In the Peruvian highlands this disease has not yet been reported, so in the present work a macro and microscopic pathological study of SCC is performed. For this purpose 3 ewes with skin tumor were taken from different parts of the Puno region, these specimens were sacrificed, necropsied and samples of tumor tissue and regional lymph nodes were taken for histopathological study. The studies were done in the Laboratory of Pathology of the Faculty of Veterinary Medicine and Animal Science, UNA Puno. The results were as follows: tumoral lesions with bleeding surface, cauliflower appearance, cut resistant and two of them strongly metastatic in regional lymph nodes were observed in the 3 cases. Microscopic lesions were chara...
