Abstract:

Meat quality is one of the most important factors for determining the efficiency of broiler production. Recently, two newly reported myopathies are gaining the more attention of poultry industry globally for their high incidence, white striping (WS) and wooden breast (WB). WS is characterized by the occurrence of white fat striations parallel to muscle fibers, while WB is mainly characterized by obvious hardening of the breast muscle. These two myopathies share similar histological lesions, and often appear together. The occurrence of the two myopathies can adversely affect meat's appearance, nutrition value and ability for further processes, which result in huge economic loss to the industry. In recent years, the study of characteristics and mechanism of WB and WS has a greater progress. Most of the studies were reported by foreign research groups, fewer by Chinese research teams. In this review, we summarized the research progress of WB and WS from the aspect of pathological features, effect on meat quality and nutrition value, and detailed mechanism in order to provide reference and theoretical basis for future studies.
