Abstract

Realizar el análisis histológico de lesiones pódales de pollos comerciales en la planta de sacrificio de Pollo Olympico S.A., Colombia con el fin de discutir aspectos sobre su retención sanitaria en plantas de sacrificio. Materiales y métodos: Se utilizó la población avícola de 10 granjas de la empresa Pollo Olympico S.A evaluando macroscópicamente 129.551 animales y microscópicamente 330 lesiones podales. El análisis histológico evaluó el tipo y la profundidad de las lesiones inflamatorias y la presencia de estructuras micóticas. Resultados: La evaluación macroscópica evidenció lesiones podales en el 64,7% de la población total de aves; la microscópica mostró un predominio de procesos inflamatorios con presentación de heterófilos (73,1%), el 19% fueron infiltrados mixtos y el 7.9% de predominio mononuclear. Las lesiones encontradas mostraron una localización principalmente subcorneal (77.9%) y la ausencia de estructuras micóticas, células gigantes o lesiones vasculares.

Objetive: To conduct histological analyses of toe lesions for commercial broiler at the slaughterhouse of Pollo Olympico S.A., Colombia, with the ultimate goal of proposing recommendations about sanitary containment. Materials and Methods: Poultry subjects were sampled in 10 farms of Pollo Olympico S.A. Macroscopic inspections were conducted on 129.551 animals while the microscopic ones were on 330 toe lesions. Histological analyses evaluated type and depth of inflammatory lesions as well as the presence of fungal infections Results: Macroscopic analyses revealed inflammatory process mediated by heterophiles (73,1%), mixed infiltrates (19%) and mononuclear (7.9%). Lesions were mainly localized at the sub-corneal level (77.9%) and showed no signs of fungal structures, giant cells or vascular presence.
