2Quintles are based on NEm residuals (formulated NEm minus growth performance-predicted NEm), where Quintile 1 has the most negative differences and Quintile 5 has the most positive differences.
3Standard error of quintile means. The largest SEM value is reported.
4Carcass-adjusted SWG, kg/dry matter intake, kg.
a,b,c,d,eRow means that do not have the same superscript differ, P < 0.05.
