Receiving Trial
Fall 2008
One hundred ninety-eight mixed breed steers (BW = 622.6 ± 34.3 lbs.) from 40 different ranches that
were part of the Dakota Feeder Calf feedout program were utilized in the receiving trial. Steers were
weighed individually at the initiation and completion of the receiving trial (30 d). Rations were
formulated (56 Mcal/lb.) to meet or exceed NRC (1996) recommendations.

Finishing Trial
Summer 2008
One hundred thirty-two yearling Black Angus cross heifers (BW = 911.5 ± 33.2 lbs.) were purchased
from a commercial source and utilized for the finishing trial. The finishing rations (65 Mcal/lb.) were
formulated to meet or exceed NRC (1996) recommendations.
Glycerol levels were increased in stepped increments as follows: all glycerol treatment groups were fed
the 6% glycerol ration during the first seven days of the trial; the 12 and 18% treatment groups were
increased to 12% during the second week; and the 18% glycerol treatment pens were increased to the
final glycerol level at the start of the third week.
Heifers were weighed at 28-d intervals during the 102 days on feed. All heifers were marketed at the
same time when visual appraisal of the animals determined that 60 percent would grade USDA choice.
