Kansas Agricultural Experiment Station Research Reports
Eighty-seven 3/8 Simmental x 5/8 Hereford heifers calved at 2 years of age and were designated as Single-Calf-Heifers (SCH). Twenty-six heifer mates that did not calve were designated as 2-year-old open heifers (2-OH), and 22, 1 year-old open heifers (1-OH) from the same source served as controls. All heifer groups were fed a high-grain diet for 112 to 137 days before slaughter.

Carcass data were obtained, and …
