The 2022 county article compares the sheep’s meat with other breeds, describing higher protein, amino-acid and ash measures and lower fat and moisture measures. It also identifies geographic-indication credentials and presents the county breeding center as a base for conservation and flock expansion. The local breed’s story thus connects selection in the plateau environment with the practical work of maintaining breeding groups and marketing a regional product.
