cated no differences (P > 0.10) between the corn rootworm protected corn and non-transgenic control corn for nitrogen intake (0.04 versus 0.04 lb/d), nitrogen digested (0.03 versus 0.03 lb/d), nitrogen retained (0.01 versus 0.01 lb/d), or nitrogen digestibility (77.30 versus 78.30%), respectively. The results of this experiment indicate that energy and nitrogen utilization are similar between d...

Two trials were conducted to determine the feeding value of sorghum distillers byproducts. Trial 1, a finishing trial, used 160 yearling steers (327 kg). Treatments consisted of dry-rolled corn (DRC) control, sorghum wet distillers grains (SWDG), sorghum wet distillers grains plus solubles (SWDGS), and sorghum dried distillers grain plus solubles (SDDGS). Distillers byproducts were fed at 40% o...

Two experiments were conducted to determine the effects of enzyme complex on in vitro dry matter (DM) digestibility for feed ingredients. The objective of experiment 1 was to screen feed ingredients that can be effective substrates for an enzyme complex, mainly consisted of β-pentosanase, β-glucanase and α-amylase, using in vitro digestibility methods. In experiment 1, the test ingredients were...

For determining variation in mineral composition and phosphorus (P) profile among streams of dry-grind ethanol production, samples of ground corn, intermediate streams, and distillers dried grains with solubles (DDGS) were obtained from three commercial plants. Most attributes (dry matter concentrations) increased significantly from corn to cooked slurry but fermentation caused most significant...

Glyphosate-resistant (GR) volunteer corn is a significant problem weed in soybean grown in rotation with corn in the midwestern United States and eastern Canada. The objective of this study was to evaluate the efficacy of glufosinate applied in single or sequential applications compared with acetylcoenzyme A carboxylase (ACCase) inhibitors applied alone or tank mixed with glufosinate for contro...

Effects of nitrogen (N), phosphorus (P), and potassium (K) fertilization on a corn/soybean cropping sequence were evaluated from 2013 to 2020 (corn planted in odd years) study initiated 1983. Corn yield was near optimum at 160 lb/a N. Phosphorus K alone increased corn 31 7 bu/a, respectively; soybean yields 22 1.7 respectively. As N increased, the response P 13 40 bu/a. The best return fertiliz...

The effect of simulated rainfall frequency on the pathogenicity of Pratylenchus zeae and P. brachyurus was studied in four greenhouse experiments. Corn and grain sorghum were watered at different intervals during predetermined cycles to create a gradient of water-stressed plants. Each experiment included nematode and uninoculated treatments. Growth reaction of plants to different frequencies of...

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 ...
