[QUOTE="Frankie, post: 739768, member: 13"] Ratios are in-herd measurments. Ratio of 100 is average.This animal was born smaller than his contemporary group if he had a birthweight ratio of 89. Yet he was heavier at weaning (ratio 107) and yearling (106) than his contemporary group. Ratios may tell you more than actual performance because they reflect performance of a group of calves managed the same way. One breeder could creep feed his calves and get higher weaning weights, but his calves' ratios will still be 100 for average performance in his herd. You couldn't compare ratios between herds.
