wheat tailings, finishing diets, steers
One hundred twenty-eight yearling steers (average initial weight 854 Ib) were fed one of four finishing diets containing (dry matter basis) either 1) 83% high moisture corn, 2) 44% high moisture corn and 37% high moisture wheat tailings, 3) 82% high moisture wheat tailings, or 4) 42% high moisture corn and 40% dry wheat tailings. Wheat tailings consisted of small wheat kernels removed during cleaning that had low test weights (41.5 to 52.0 Iblbushel) and high vomitoxin levels (1 7 to 42 ppm). High moisture wheat tailings were coursely cracked, reconstituted to 29% moisture, and ensiled. Dry wheat tailings were cracked only. Average daily gain declined up to 25% (P<.01) with increasing levels of high moisture wheat tailings as a result of a linear decline in dry matter intake (P < .05). Feed efficiency tended to worsen (P< .14). However, calculated net energy values for high moisture wheat tailings were similar to that of corn. Dry wheat tailings, on the other hand, resulted in similar intake (P> .20) but 1 5% lower average daily gain (P< .01) than high moisture wheat tailings fed at a comparable level and net energy values were approximately 75% of corn. Wheat tailings, regardless of form or level, decreased quality grade (P < .05) but did not affect dressing percent, yield grade, or liver abscesses (P> .20).
