Effects of grazing residues or feeding corn from a corn rootworm-protected hybrid (MON 863) compared with reference hybrids on animal performance and carcass characteristics.
One grazing and two feeding experiments were conducted to compare the feeding value of corn residue or corn grain from a genetically enhanced corn hybrid (corn rootworm-protected; event MON 863) with nontransgenic, commercially available, reference hybrids. In Exp. 1, two 13.7-ha fields, containing corn residues from either a genetically enhanced corn root-worm-protected hybrid (MON 863), or a ...
متن کاملEffects of Feeding Insect-Protected Corn and Corn Residue to Cattle, and Evaluation of Distillers Grains Storage when Mixed with Crop Residue on Cattle Performance
One grazing and two feeding experiments were conducted to compare the feeding value of corn grain, corn silage, or corn residue from a second generation insect protected (Bt) hybrid (MON 89034) developed by Monsanto including two proteins (Cry1A.105 and Cry2Ab2) with a non-transgenic parental hybrid (PAR), and two commercially available non-transgenic reference hybrids (REF1 and REF2). Diets fo...
متن کاملUtilization of Bt corn residues by grazing beef steers and Bt corn silage and grain by growing beef cattle and lactating dairy cows.
Three experiments were conducted to evaluate the impact of the Bacillus thuringiensis (Bt)-11 transformation event in two parental corn hybrids differing in date of maturity on beef and dairy cattle performance. Sixteen lactating Holstein dairy cows in replicated 4 x 4 Latin squares were assigned to four diets in a 2 x 2 factorial arrangement: Bt vs non-Bt trait and early- vs late-maturing corn...
متن کاملWinter grazing system and supplementation during late gestation influence performance of beef cows and steer progeny.
A 2 x 2 factorial study evaluated effects of cow wintering system and last trimester CP supplementation on performance of beef cows and steer progeny over a 3-yr period. Pregnant composite cows (Red Angus x Simmental) grazed winter range (WR; n = 4/yr) or corn residue (CR; n = 4/yr) during winter and within grazing treatment received 0.45 kg/d (DM) 28% CP cubes (PS; n = 4/yr) or no supplement (...
متن کاملLivestock Performance: Feeding Biotech Crops
To date, genetically enhanced plants in the marketplace that are used as feeds for livestock are based on producing insecticidal compounds or developing herbicide tolerance. Corn grain, whole plant green chop corn, corn silage, corn residue, soybeans, and soybean meal from the current genetically enhanced plants have been fed to chickens, sheep, beef cattle, and dairy cows and compared with fee...
