1 Impact of Body Weight Gain During Stocker/Backgrounding on Feedyard Performance and Carcass Traits Galen E Erickson University of Nebraska-Lincoln gerickson4@unl.edu

27 Calf-feds Lower DMI/d, lower ADG, better efficiency Increased days in feedlots Marketing flexibility limited (70% calves spring born) Yield grade discounts an issue (too fat) Lower carcass weights Yearlings Greater DMI/d, greater ADG, poorer efficiency Less days on feed Overweight carcasses an issue (SORTING?) Leaner, grade better? More flexibility on marketing Healthier (in the feedlot anyway)

47 Conclusions: BW gain on finishing Some impact, but small on subsequent ADG If all pasture grazing, greater impact? Is silage different? Same is true for G:F Growing makes cattle bigger at same fatness Slower gain, bigger at equal fatness Measures on a per day basis, not a big impact Can t determine whether pasture & drylot behave similarly Certainly more points needed within studies (almost all just 2 points)
