Caracterización de la patología pulmonar en corderos de cebo del sur-oeste de Extremadurafactores de riesgo y parámetros de estrés asociados

Abstract

One of the main problems affecting the profitability of sheep and goat farms constitutes respiratory disease. Lung infections and its inflammatory problems, is a cause of significant morbidity and mortality in the period of breeding and fattening in ovine. Many factors can influence the development of this disease. Among others, influence in their presentation, inherent host factors mainly associated to the immunity of the animals, and environmental conditions, both those from climatology and other of the area, as well as the result of management in this period of life of the animals. Therefore, a study was conducted to analyze the ovine pulmonary pathology found in slaughterhouse and the possible factors that can come into your presentation during your stay in the feedlot. For this fact, physiological parameters (hematologic, hormonal and of stress response), environmental and pathologic were evaluated and their possible relationship in order to point out possible improvements to mitigate the direct and indirect losses in the affected farms. Finally, an immunohistochemical study have been performed in order to analyze the possible evolution of the found pathological processes during the fattening period in order to establish measures based on the use of pharmacological and biological products to avoid the development of severe lesions.
