Abstract
Evidence of genetic improvement in the Department of Lands and Survey's Angus Breeding Scheme (ABS) was examined. Data from the ABS project and from the pilot Angus Sire Reference Scheme (ASRS) were used to estimate genetic trend in weaning weight and yearling weight in the ABS nucleus by regressing sire group values on year of birth. Estimated genetic improvement in weaning and yearling weight used the ABS data were 1.6
