Exploring the breed-specific variations in meat quality attributes and gene expression patterns associated with tenderness, intramuscular fat, and fatty acid composition profiles in nellore and deecani sheep breeds of india

NPNavya PothireddyVMVishnuraj M.RKRK. Vijaya Rachel

Key Points

  • The research aims to explore how different sheep breeds affect meat quality attributes and gene expression related to tenderness and fat content.
  • Comparison of Nellore and Deccani sheep breeds under extensive feeding systems
  • Assessment of meat quality attributes including tenderness and intramuscular fat
  • Analysis of gene expression patterns related to meat characteristics
  • Deccani breed exhibited higher intramuscular fat and better flavor potential
  • Nellore breed was noted for its balanced proteolytic activity and leaner meat composition
  • Differences in fatty acid compositions were observed, favoring Deccani sheep

Abstract

This study demonstrated clear differences between the two sheep breeds evaluated under extensive feeding systems. The Deccani breed offers superior IMF and flavour potential, along with a high amount of desirable fatty acids. Conversely, the Nellore breed's balanced proteolytic activity and leaner composition made it favourable for tenderness.
