Aspectos anatomopatológicos da miopatia peitoral profunda em frangos de corte abatidos sob inspeção sanitária

Abstract: A miopatia peitoral profunda é uma enfermidade poligênica, caracterizada pela necrose do músculo supracoracóideo de frangos de corte e perus comerciais. A lesão é causada pela isquemia local, resultado do intenso melhoramento genético dessas aves, na tentativa de selecionar animais com musculatura peitoral bem desenvolvida. Neste estudo foram realizadas descrições macroscópicas e microscópicas de lesões consideradas típicas de miopatia peitoral profunda. Foram colhidos fragmentos do músculo supracoracóideo de … Show more

“…Anatomopathological aspects of DPM in broiler and reported the presence of muscle lesions in both the Pectoralis minor (tender) and the Pectoralis major (though at a lower intensity) muscles, with presence of fibrovascular tissue and foci of regeneration in the area peripheral to the lesions ( Vieira et al, 2006 ). Thus, the damaged fibers were probably replaced with adipose tissue, during the process of regeneration of the injured tissue, which may explain the increased lipid content and changes chemical components of the breast fillets ( Pectoralis major muscle).…”
