摘要:

盐池滩羊是宁夏当地的优良特色畜种,因其肉质鲜嫩、膻味轻、大理花纹明显而深受消费者青睐。但随着封山禁牧政策的实施和舍饲圈养的现代化畜牧业发展,致使滩羊肉品质下降,故提升滩羊肉质风味,改善肉品质性状成为研究者及生产者关注的重点,而明确滩羊肉质特征及其影响因素的作用机制对于提升羊肉品质具有重要意义。本研究从营养、遗传和环境阐述其对肌内脂肪沉积和肌纤维分化的影响及作用机理,重点总结了瘤胃微生物对滩羊肉品质的代谢调控作用, 以期为提高滩羊肉品质奠定理论基础。

Abstract:

The Yanchi Tan sheep is an excellent local breed in Ningxia, China. It is highly favored by consumers because of its tender meat, light mutton flavor, and distinct marbling. However, the implementation of mountain enclosures and grazing ban policies, coupled with the development of modern intensive animal husbandry, has led to a decline in the meat quality of Tan sheep. Improving the flavor and quality characteristics of Tan sheep meat has become a key focus for both researchers and producers. Elucidating the meat quality traits of Tan sheep and the underlying mechanisms of the influencing factors is of great significance for enhancing the overall quality of sheep meat. This study explores the effects and mechanisms of nutrition, genetics, and environment on the deposition of intramuscular fat and muscle fiber differentiation. In particular, we focus on how the metabolic regulation of rumen microbiota affects the meat quality of Tan sheep. The results of this study provide a theoretical knowledge base to guide efforts in improving the meat quality of this breed.
