a Ratio of the number of animals with self-trained phenotypes to that with measured phenotypes and b maximum improvement of the correlation (%). Incremental improvement in accuracy of prediction measured as the correlation between predicted and actual residual feed intake phenotypes within a replicate due to additional animals with self-trained phenotypes was smaller than 0.01%. The numbers of animals with measured phenotypes were 300, 400, and 500, whereas the numbers of animals with self-trained phenotypes started with 200 and increased in increments of 200 additional animals. Error bars indicate the 95% confidence intervals for means of 100 replicates
