关于肉鸡胸肉中出现白色条纹的市场报道一直在增加，这在肉鸡肉类行业引起了对消费者接受度的负面影响的担忧。进行该研究以宏观和显微镜表征在42日龄屠宰的Cobb 500肉鸡胸肉片上不同严重程度的白色条纹的状况。屠宰了2，512只出现白色条纹的肉鸡尸体，并根据条纹的严重程度进行了宏观分类，分为中度或重度;进一步的组织学显微镜评价表明中度和重度病例均存在退行性肌病，但75%的胸鱼片被归类为中度。典型地，宏观分类为中度的样本仅显示显微镜下坏死（65.17%）或中度多灶性坏死（9.83%），而分类为重度的样本显示弥漫性和强烈坏死（25.00%）。对于所研究的任何一种程度的白色条纹，都没有观察到结缔组织的增殖，将该特征描述为急性发生。
Market reports of white striping in broiler breast fillets have been increasing, which has generated concerns in the broiler meat industry regarding negative effects on consumer acceptance. this study was conducted to macro-and microscopically characterize the condition of white striping at varying degrees of severity on Cobb 500 broiler breast fillets slaughtered at 42 d of age. Carcasses of 2,512 broilers presenting white striping were slaughtered and macroscopically classified according to the degree of severity of the striations as moderate or severe; further histological microscopic evaluation demonstrated degenerative myopathy in both moderate and severe cases, but 75% of those breast fillets were classified as moderate. typically, the samples classified macroscopically as moderate showed microscopic necrosis only (65.17%) or moderate multifocal necrosis (9.83%), whereas those classified as severe showed diffuse and strong necrosis (25.00%). the proliferation of connective tissue was not observed for either of the degrees of white striping investigated, characterizing this profile as an acute occurrence.
