During the last 60 years the size of the breast muscle was increased through the improvements in the growth rate and yield of the chicken broilers. By introducing different genetic selection and application with improvement of chicken nutrition and management led finally to serious breast meat abnormalities that influenced their quality and left a negative impact on broiler meat sector. The most prevalent abnormalities include Deep Pectoral Muscle myopathy (DPM) green muscle disease or Oregon disease, White Striping (WS), and Woody Breast (WB). Every year an extensive research all over the world on the real causes of breast muscles condemnation was conducted in order to reduce both breast muscles abnormalities and financial losses. Therefore this study was conducted by inspection of 3.720.000   chicken broiler carcasses at North Delta abattoir, Egypt during chicken processing the incidence of Green Muscle (with their three stages), white Strips and Wooden Breast were 20280 (0.5% ) , 1248 (0.03%)  and 1872 (0.05%) respectively. The total economic loss during 2019 for green muscle abnormality according to the Egyptian salary was 124800 L.E., for WS and WB were 31200 and 48800 L.E respectively.
