Ethanol byproducts or coproducts (I may use the two terms interchangeably) result from the fermentation of grains, typically corn, to produce ethanol – either for fuel use or for human consumption plus distillers grains and possibly other byproducts. Most of the ethanol produced in the U.S.A. today is via dry grinding, with dried distillers grains plus solubles (DDGS) as the main byproduct (Rau...

Flint corn has a greater proportion of vitreous endosperm than dent corn (Philippeau et al, 1999). Philippeau and Michalet-Doureau (1997) observed that increased kernel vitreousness was associated with decreased ruminal starch degradation. Increased kernel vitreousness may explain the reduction in total-tract starch digestibility observed for mature whole-plant corn silage (WPCS; Bal et al., 19...

Nutrient composition of commercial corn grain appears to have changed little in the last 10 to 15 years. Although the data for sorghum grain and barley are more limited, no dramatic changes in nutrient composition were apparent. Flaking corn appears to reduce the crude protein concentrations, perhaps because water used for starch gelatinization is not released during drying. Harvesting and stor...

Samples were analyzed from three metabolism trials to evaluate the effects of dietary phosphorus (P) intake on P excretion in beef steers fed corn-based finishing diets. In Experiment I, ten steers were fed ten diets that involved two processing methods, whole and dry rolled corn and five corn sources, commodity, white, high oil, high protein, and highoil-high-protein corn. In Experiment II, si...

Feedlot cattle performance data from 20 trials (n = 350 pen means; representing 3,365 steers) evaluating dietary inclusion of corn wet distillers grains plus solubles (WDGS) were summarized with two meta-analyses. The objective of this study was to evaluate the effects of WDGS inclusion level with dry-rolled corn (DRC) or a blend of DRC and high-moisture corn (HMC) for either calf-feds or yearl...

The ability of Multi-Layer Perceptron (MLP) and Neuro-Fuzzy neural networks to classify corn seed varieties based on mixed morphological and color Features has been evaluated that would be helpful for automation of corn handling. This research was done in Islamic Azad University, Shahr-e-Rey Branch, during 2011 on 5 main corn varieties were grown in different environments of Iran. A total of 12...

Two hundred sixty-four crossbred heifers (initial BW = 354 kg ± 0.5) were used to determine effects of corn processing method and wet distillers grains plus solubles (WDGS) inclusion in finishing diets on animal performance, carcass characteristics, and manure characteristics. The study was conducted as a randomized complete block with a 2 × 2 factorial arrangement of treatments. Dietary treatm...

Introduction Organic sweet corn can be successfully grown in Iowa, based on our agricultural resources and our extensive experience with field corn production. With the continuing growth of organic consumers in the U.S., premium prices can be obtained for organic sweet corn from Iowa. With the potential for major markets across the U.S. identified, research on production, harvesting and process...

Four experiments were conducted to investigate the effects of ractopamine hydrochloride (RAC) on ruminal fermentation and proteolysis. In Exp. 1, in vitro gas and VFA production was measured in flasks incubated with 0, 0.226, 2.26, 22.6, and 226.0 mg of RAC/L of buffered ruminal fluid. Ractopamine hydrochloride had a quadratic effect on in vitro gas production (P < 0.05; 177, 181, 185, 190, and...

harvesting corn created annually a large amount of organic waste, which could be a suitable initial substrate for vermicomposting due to its high c/n ratio. the present study was aimed for recycling of corn residues and production of good quality vermicompost, after processing by eisenia fetida. the setup of experiments was conducted with 40, 60 and 80% of corn residue, compost, cow dung and pa...
