Effect of normal vs opaque-2 vs roasted normal corn and normal vs opaque-2 corn silage for finishing beef cattle - Illinois (United States of America) : American Society of Animal Science, 1975.

Peer review

Two metabolism studies and one feedlot trial were conducted to evaluate opaque-2 corn, opaque-2 corn silage and roasted normal corn for finishing beef cattle. Metabolism studies indicated no significant advantages for opaque-2 corn grain or silage over their normal counterparts. Normal corn silage contained more (P<.05) digestible energy and produced higher levels (P<.05) of rumen ammonia than opaque-2 corn silage. Feedlot trial results indicated that roasted normal corn was nutritionally superior to either normal or opaque-2 corn. Steers fed roasted normal corn gained faster (P<.05) than steers fed normal or opaque-2 corn, while normal corn produced higher gains (P<.05) than opaque-2 corn. Steers fed the normal corn silage gained faster (P<.05) than those fed opaque-2 corn silage. Steers fed normal corn silage had higher (P<.05) carcass grades than those- fed opaque-2 corn silage. Cattle fed normal corn and roasted normal corn had larger (P<.05) loin-eye areas than steers fed opaque-2 corn.
