Feedlot performance and carcass traits were compared among 118 steers and heifers of
various three-breed crosses. The heifers were placed in feedlot directly after weaning, and
the steers were grazed on wheat pasture and placed in feedlot as yearlings. Shorthorn
and Red Poll were used as the sire breeds. On the average, differences in calf performan-
ce between these two sire breeds were not large but consistently favored the Shorton si-
res. Calves sired by Shorthorn bulls were in the feedlot six fewer days gained 0.29 pounds
more per day, were 52 pounds heavuer at slaughter, and required 0.4 pound less feed per
pound of gain than calves sired by Red Pol bulls. These three-breed cross calves were
produced by seven different kinds of two-breed cross cows (Hereford x Angus, Simmental
x Angus, Simmental x Hereford, Brown Swiss x Angus, Brown Swiss x Hereford, Jersey x Angus, and Jersey x Hereford). Calves from the Jersewy cross cows required the least
amount of days on feed (129 days) and hence had one of the lightest slaughter weights at
818 pounds. Calves from Brown Swiss cross cows averaged 141 days infeedlot with one of the heaviest weights at 903 pounds. The Brown Swiss and Simental crosses averaged
0.35 pounds/day more rapid gain than the Jersey crosses but required eight to 12 days
longer on feed to grade choice. Calves from Hereford x Angus, Simmental crosses, and Brown Swiss x Hereford cows had similar feed efficiency (averaged 7.52 pounds of feed
per pound of gain) and were more efficient than the Brown Swiss x Angus and Jersey
crosses by 0.65 pounds of feed per pounds of feed per pound of gain on the average. Di-
fferences among cross bred cow groups with respect to carcass traits were not large. MenosFeedlot performance and carcass traits were compared among 118 steers and heifers of
