Corn oil and corn meal obtained from corn are included in useful products. A method for producing fermentation-based products comprises combining corn meal with water and an enzyme, and mixing the combination with a micro-organism capable of fermenting a carbon source to produce a fermentation-based product. The corn meal is produced by cracking whole corn, conditioning the whole corn and extracting the whole corn to produce corn meal without flaking the corn during processing. The corn grain process generally includes the steps of cracking corn grain having a total oil content of from about 3% by weight to about 30% by weight and extracting a corn oil from the cracked corn grain.

A closed-loop cyclic utilization technology for the technological water in the procedure of preparing corn starch is disclosed. After the technological water is used to prepare sulfurous acid and immerse corn grains in it, it flows in technological water pool behind evaporation, condensing and regulating pH value.

A feed delivery system for a dairy farm wherein a third-party supplier of the system can provide the dairy farm with lists of approved hybrids for the feed components, necessary information inputs for practicing the feed method, and all or a portion of its component needs for the feed ration corresponding to a feed ration that contains: at least one primary forge source selected from the group consisting of brown midrib corn silage, dual-purpose corn silage, leafy corn silage, and grass silage; a secondary forage source selected from the group consisting of dual-purpose corn silage, alfalfa haylage, alfalfa dry hay, grass silage, and alfalfa/grass mix; a corn grain of floury and/or vitreous endosperm starch grain into which normal dent corn or mutt corn may be blended in order to achieve a predetermined level of in vitro starch digestibility; such grain component being further processed to produce a specific particle size of the blended starch. The feed delivery system can also provide the dairy farm with real-time characterizations of at least some of its feed ingredients, and re-penning strategies for maximizing the milk productivity of the cows.

A computer-based system for characterizing in real time the nutritional components of one of more ingredients for a ruminant feed ration, including dry matter, NDF, NDFd, lignified NDF ratio, peNDF, percent starch, IVSD, and particle size for a forage material; and IVSD and particle size for a grain material. The system utilizes proprietary NIRS equations based upon prior samplings of a variety of crop species like dual-purpose corn silage, leafy corn silage, brown midrib (“BMR”) corn silage, grass (silage/dry), alfalfa (silage/dry), BMR forage sorghum, normal dent starch grain, floury endosperm starch grain, vitreous endosperm grain, and steam-flaked corn grain, and applies those equations to current samplings of a corresponding crop to predict in real time the characteristics of such forage or grain material. The real-time characterization system may also utilize the predicted data to calculate a “total ration fermentation index” value that takes into account the total NDFd and IVSD characteristics (including RAS and RBS) of the forage and starch ingredients to be used in a feed ration to ensure that the ration will not contribute too much or too little digestibility to the cow. A “flash fermentation index” identifies feed formulations, based upon the real-time characterizations of the ingredients, that are too “hot” to feed to the cows without incurring the risk of lost production and adverse health issues.

The ability of two Aspergillus flavus Link isolates (CT3 and K49) to reduce aflatoxin contamination of corn was assessed in a four-year field study (2001 to 2004). Soil was treated with six wheat inoculant treatments: toxigenic isolate F3W4; the non-toxigenic isolate K49; the non-aflatoxigenic isolate CT3, two mixtures of CT3 or K49 with F3W4; and an autoclaved wheat control, applied at 20 kg/ha. In 2001, inoculation with the toxigenic isolate increased corn grain aflatoxin levels by 167% compared to the non-inoculated control, while CT3 and K49 inoculation reduced aflatoxin levels in corn grain by 86% & 60%, respectively. In 2002, inoculation of CT3 and K49 reduced aflatoxin levels by 61% and 76% compared to non-inoculated controls, respectively. In 2001 mixtures of toxigenic and non-toxigenic isolates had little effect on aflatoxin levels, but in 2002 inoculation with mixtures of K49 and CT3 reduced aflatoxin levels 68 and 37% compared to non-inoculated controls, respectively. In 2003 and 2004, a low level of natural aflatoxin contamination was observed (8 ng/g). However, inoculation with mixtures of K49+F3W4 and CT3+F3W4, reduced levels of aflatoxin 65 to 94% compared to the toxigenic strain alone. Compared to the non-sclerotia producing CT3, strain K49 produces large sclerotia, has more rapid in vitro radial growth, and a greater ability to colonize corn when artificially inoculated, perhaps indicating greater ecological competence. Results indicate that non-toxigenic, indigenous A. flavus isolates, such as strain K49, have potential use for biocontrol of aflatoxin contamination in southern U.S. corn.
