The European corn borer completes two to three generations per year in Illinois. Fourth and fifth instars tunnel in stalks, causing disruption in the flow of water and nutrients in the plants. The cavities created by the borers may weaken stalks and ear shanks, resulting in lodging or dropped ears. Before the advent of Bt corn, producers attempted to control European corn borers, if the need ar...

A genetically modified Bt176 corn hybrid, which contains an insecticidal protein against the European corn borer, and its conventional, nonmodified counterpart were evaluated in 4 separate trials to verify substantial equivalence in feeding value and animal performance. Thirty-six individually kept laying hens and 3 replicates of 94 broiler chickens each, assigned to 12 cages, were fed 2 differ...

Cholecystokinin (CCK) release and gall bladder emptying in response to a fatty meal are completely abolished in coeliac disease. To determine the effect of lipid digestion on CCK release and gall bladder motility, six patients with untreated coeliac disease and a flat jejunal mucosa were studied on two separate days. After an overnight fast, the plasma CCK concentration and gall bladder volume ...

Corn processing techniques differ in their effects on feedlot performance and carcass characteristics of finishing cattle. Capacity of a feedlot (critical mass) can dictate which processing method is most feasible economically due primarily to fixed costs for equipment. The local and regional corn pricing basis and availability of other ration ingredients also can influence which corn processin...

Plant resistance is a promising control method for the two most damaging insect pests of maize, Zea mays L.: the European corn borer, Ostrinia nubilalis (Hübner), and the western corn rootworm, Diabrotica virgifera virgifera LeConte. Fifteen experimental lines of maize, derived from a backcross breeding program designed to introgress resistance to European corn borer from Peruvian maize into tw...

Two finishing trials were conducted to determine the effects of adding different types of corn bran, a component of corn gluten feed, on cattle performance. In Trial 1, 60 English crossbred yearling steers (283 +/- 6.7 kg) were used in a completely randomized design with four dietary treatments. Treatments were diets with no corn bran, dry corn bran (86% DM), wet corn bran (37% DM), and rehydra...

Three experiments evaluated the lipids in distillers grains plus solubles compared with corn or other sources of lipid in finishing diets. Experiment 1 utilized 60 individually fed yearling heifers (349 +/- 34 kg of BW) fed treatments consisting of 0, 20, or 40% (DM basis) wet distillers grains plus solubles (WDGS), or 0, 2.5, or 5.0% (DM basis) corn oil in a finishing diet based on high-moistu...

Materials and Methods The Neely-Kinyon Long-term Agroecological Research (LTAR) site was established in 1998 to study the long-term effects of organic production in Iowa. Treatments at the LTAR site, replicated four times in a completely randomized design, include the following rotations: conventional corn-soybean (C-S), organic corn-soybean-oats/alfalfa (C-S-O/A), organic corn-soybean-oats/alf...

Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...
