Growth and Carcase ASBVs Work

Sheep CRC - Information Nucleus Flock Background Sheep CRC initiated large scale progeny test of young industry sires - some with ASBVs Measuring an extensive range of traits across differing environments Aims – increase genetic progress through – increased industry linkage – generate info on new and hard to measure traits – generating genomic information
