Abstract

Seven commercially available corn hybrids representing a range within and among kernel traits were used in a finishing trial to evaluate effects of corn kernel traits on feedlot animal performance. Average daily gain, DMI, and hot carcass weight were similar among all corn hybrids. A significant difference in feed conversion of 8.4% from lowest to highest among hybrids was observed. Kernel traits correlated with feed conversion were 1,000 grain weight, stenvert time to grind, and stenvert proportion of soft to coarse particles. Efficiency of finishing cattle gain can be significantly improved by selection of corn hybrids with more desirable kernel traits.
