The regression of daughter on dam first-lactation milk deviations from herd-mate averages was found to be linear from an analysis of 47,400 Holstein pairs.The linear equation was y=-25.6 + .210(x -27.6) and the quadratic equation was y-----25.6+ .208(x -27.6) + .0000222(x~-44131.4)with correlation coefficients, .18258and .18268,respectively.These results suggest that selection response can be predicted adequately even with very large selection differentials.
