Uruguay's national sheep performance recording scheme (Flock-Testing Service) is described. Recent developments of the scheme are discussed. The scheme is implemented and supervised by the Uruguayan Wool Secretariat (SUL). Centralization of responsibilities by SUL and continued co-participation of breeders and scientists are identified as the main factors contributing to the scheme's success. It is suggested that Uruguay's Flock-Testing Service combines traditional and scientific breeding methods in a balanced manner, thus assisting with the improvement of the genetic merit of the national flock.
