这篇综述是家禽科学协会研讨会的摘要,该研讨会讨论了肉鸡胸肉中的肌病,专注于遗传学之间的相互作用,营养,畜牧业,和肉类加工。描述了胸大肌主要肌病(木质乳房[WB];白色条纹[WS];意大利面条[SM])和胸小肌(“羽毛”),然后讨论它们的患病率,潜在原因,当前和未来的缓解方法,以及检测方法(在活禽和肉中)以及利用受影响肉的方法。总的来说,乳腺肌病仍然是整个家禽业的重要焦点,同时收集了大量的数据和知识,很明显,还有很多东西需要理解。由于有多种因素影响乳腺肌病的发生,它们的减少依赖于整体方法。家禽育种者正在进行的平衡育种策略针对的是长期遗传因素,但理解非遗传因素(短期解决方案,如营养)的重大影响仍然是机会的关键领域。因此,通过鸟类的生命了解肌肉的生理和生物学需求对于减少肌病至关重要(例如,尽量减少氧化应激),并更深入地了解它们的病因。
This review is a summary of a Poultry Science Association symposium addressing myopathies in broilers\' breast meat, focusing on the interactions between genetics, nutrition, husbandry, and meat processing. The Pectoralis major myopathies (woody breast [WB]; white striping [WS]; spaghetti meat [SM]) and Pectoralis minor (\"feathering\") are described, followed by discussing their prevalence, potential causes, current and future ways to mitigate, as well as detection methods (in live birds and meat) as well as ways to utilize affected meat. Overall, breast myopathies remain an important focus across the poultry industry and whilst a lot of data and knowledge has been gathered, it is clear that there is still a lot to understand. As there are multiple factors impacting the occurrence of breast myopathies, their reduction relies on a holistic approach. Ongoing balanced breeding strategies by poultry breeders is targeting the longer-term genetic component but comprehending the significant influence from nongenetic factors (short-term solutions such as nutrition) remains a key area of opportunity. Consequently, understanding the physiology and biological needs of the muscle through the life of the bird is critical to reduce the myopathies (e.g., minimizing oxidative stress) and gain more insight into their etiology.
