What is the main feature of meat or terminal sire breeds of sheep?

The main feature of meat or terminal sire breeds of sheep is their high feed efficiency and muscularity. These breeds have been specifically selected and bred to produce quality meat, characterized by their robust bodies and good muscle development. This musculature is essential for meat production, as it allows for higher yields of meat when animals are harvested. In addition, high feed efficiency means these sheep convert feed into body mass effectively, which is crucial for economic meat production on farms.

The focus on muscularity and feed efficiency is what differentiates meat-producing breeds from those bred primarily for wool or other traits. Therefore, selecting for these characteristics ensures that the terminal sire breeds contribute optimally to the meat supply while supporting sustainable agricultural practices.
