Drouillard et al. (2002) received weaned calves for
36 to 40 days on diets that contained tallow and either 0
percent, 5 percent, 10 percent, 15 percent or 20 percent
flax, then finished calves from the tallow and 10 percent
flax diets on a common finishing diet, and reported that
those cattle fed 10 percent flax had higher marbling
scores than the steers offered tallow (Sl60 vs Sm00,
respectively.) Additionally, Drouillard et al. (2004) fed
Holstein steers 0 percent or 5 percent flax for either 109
or 157 days and reported that flax addition increased the
percentage of steers that graded USDA choice.
