Terminal Sire Breeding Evaluation manual

In the 25 years since the introduction of across-flock evaluations, more than 3 million terminal sire sheep records have been analysed by Signet Breeding Services. This analysis has been carried out by using a dataset of over 650,000 ultrasound scans for muscle and fat depth, and over 10,000 images from computed tomography (CT). The UK breeds sheep with world-leading terminal sire genetics and has some of the best tools for measuring and analysing sheep in the world.
