Use of expected progeny differences for marbling in beef. I. Production traits

Six Angus bulls with HIGH (>. 4) and six bulls with LOW ( -.18). More (P < -.05) carcasses of calves from sires with HIGH EPD for marbling graded USDA Choice than from LOW EPD sires, 74% vs 47%, respectively. Angus sires can be selected to produce progeny that have increased ability to grade C...

Zusammenfassung:	Six Angus bulls with HIGH (>. 4) and six bulls with LOW ( -.18). More (P < -.05) carcasses of calves from sires with HIGH EPD for marbling graded USDA Choice than from LOW EPD sires, 74% vs 47%, respectively. Angus sires can be selected to produce progeny that have increased ability to grade Choice without increasing yield grade or decreasing animal growth or feed efficiency.
