Gene expression profiles in specific skeletal muscles and meat quality characteristics of sheep and goats

Abstract

Lamb meat is highly valued across various cultures and regions due to its unique flavor and nutritional benefits. As the primary component of edible meat, skeletal muscle holds significant economic value and research importance. However, previous studies have largely focused on a limited array of muscle groups, overlooking the differences between various types. Therefore, a comprehensive transcriptomic and meat quality analysis of the skeletal muscles of sheep and goats is essential to improve meat production traits. In this study, we performed RNA sequencing and assessed meat quality in 10 different skeletal muscles from 2-year-old Liangshan Black sheep and Meigu Black goats. We generated 803.16 Gb of high-quality bulk RNA sequencing data with six biological replicates for each muscle. This dataset provides a deeper understanding of the gene expression profiles and meat quality characteristics of different muscle tissues in sheep and goats, laying the foundation for broader comparative research.
