At the beginning of the study, a large majority of the steers were graded as utility. The average market grade of the steers, at the end of the trial was a high standard. The average federal carcass grade was slightly higher than the average assigned market grade of these steers (Table 3). Although actual individual ratings were made by thirds of a grade, these values were combined within the recognized grade standards for this report. There was no significant differences in carcass grades between ration groups. Table 3. Number of Steers within each grade at three classification periods.

The average dressing percentage for all 32 steers was 58.7 percent and the carcasses shrank an average of 1.7 percent during a 48 hour chill period. Although differences between the ration groups in dressing percentages and shrink were rather small (Table 4) they were statistically significant. Table 4.
