Accuracy of selection is an important feature for all breeding programs and genetic evaluation systems, with genetic gain influenced by the accuracy of the breeding values and by the selection decisions taken by the breeder. Accuracy of estimated breeding values (eBVs) are affected by the amount and quality of the pedigree and performance data recorded. With increasing use of breeding values based on across–flock analyses, the impact of various data recording practises used in sheep flocks needs investigation to ensure practises by any particular breeder do not adversely affect the whole analysis.
