I wouldn't breed heifers to a 6. Fall you could probably get away with it. Does the bull have performance data going into the accuracy of his EPDs? Genomic Test? His daddy is a +1 CED and 3.2 BW. If the +6 is just a pedigree estimate you are playing with fire.
If you want to keep his daughters and run your cattle without supplemental feed at full stocking rate the 32 Milk and - $26 $EN are not the numbers you want.
