Pathological Examination of Deep Pectoral Myopathy in House Reared Broilers

Derin Pektoral Myopati (DPM), broyler ve hindilerin pektoral kaslarında fokal nekroz, kanamalar ve yeşil renk değişikliği ile karakterize bir hastalıktır. Etkilenen kasların lezyonları kesimden sonra ve et parçalama sırasında fark edilir. DPM etlik kanatlı endüstrisinde önemli ekonomik kayıplara neden olabilen bir hastalıktır. Bu çalışmanın amacı köy koşullarında yetiştirilen bir broyler sürüsünde saptanan DPM olgusunun makro ve mikroskobik bulgularını incelemektir. Bu çalışmada, 12 adet köy koşullarında yetiştirilmiş, 100-120 günlük broylerlerde saptanan DPM'de patolojik bulgular incelenmiştir. Bütün tavuklar klinik olarak sağlıklı görünümde iken kesim sonrası et parçalama işlemi sırasında pektoral kaslarda kanama ve yeşil renk değişikliği fark edildiği bildirildi. Histopatolojik inceleme için lezyonlu kaslardan örnekler alındı. Mikroskobik incelemede pektoral kaslarda nekroz, hiyalinizasyon ve kanamalar izlendi. Bazı olgularda yangısal hücre infiltrasyonları ve göğüs kaslarında atrofi mevcuttu. Hastalığa karakteristik makro ve mikroskobik bulgulara göre DPM tanısı kondu

Köy Koşullarında Beslenen Broylerlerde Saptanan Derin Pektoral Myopatide Patolojik İncelemeler

Deep pectoral myopathy (DPM) is a disease characterized by focal necrosis, hemorrhages, and green discoloration in the pectoral muscle of broilers and turkeys. The lesions of the affected muscles are usually detected during dissection after slaughter. DPM causes significant economic losses in the poultry meat industry. The purpose of this study was to investigate the gross and microscopic findings in a housereared broiler flock with DPM. In this study, the pathological findings of 12 house reared 100-120-day-old broilers with DPM were examined. All birds were clinically healthy but hemorrhages and green discoloration were detected on the pectoral muscle mass during dissection. Samples were collected from the lesioned muscles for a histopathological examination, which revealed necrosis, hyalinization, and hemorrhage. Inflammatory cell infiltration and atrophy of breast muscles was present in some cases. DPM was diagnosed based on gross characteristics and microscopic findings
