The poultry and swine industries are in the business of producing muscle protein in a cost-effective manner. While great strides have been made in improving the efficiency of muscle protein deposition, several myopathies have appeared that diminish the quality of chicken and pork meat products. The term myopathy can have a broad definition, such as a common disease of muscle, or a more specific definition, such as a malfunctioning cell structure and metabolic abnormalities that ultimately cause loss of force production and contractile dysfunction. Poultry myopathies include white-striping, spaghetti meat, and woody breast, the most common abnormality (Caldas-Cueva and Owens, 2020). Within the pork industry the ham halo condition has become a major concern. The prevalence, cause and impact of these myopathies on the meat industry were the subject of the 2020 Meat Science and Muscle Biology Symposium.

家禽和猪肉肌肉缺陷和肉质——后果、原因和管理。

家禽和养猪业以具有成本效益的方式生产肌肉蛋白。虽然在提高肌肉蛋白质沉积效率方面取得了很大进展，但出现了几种降低鸡肉和猪肉产品质量的肌病。术语肌病可以有广泛的定义，例如常见的肌肉疾病，或者更具体的定义，例如细胞结构故障和代谢异常，最终导致力产生损失和收缩功能障碍。家禽肌病包括白色条纹、意大利面肉和木质乳房，这是最常见的异常（Caldas-Cueva 和 Owens，2020）。在猪肉行业，火腿晕圈状况已成为一个主要问题。患病率，
