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 invention discloses a method for preparing starch nanocrystal, and belongs to the field of modified starch processing. The method is based on the principle that lipid layers in waxiness corn starch grains have resistance for acid, the starch is prompted to be crushed because of homogenization treatment under a certain pressure, the lipid is prompted to be digested through Soxhlet extraction by using an alcohol-water solution, a pore structure from outside to inside is formed, then the resistance to the acid is eliminated, and the penetration of the acid inside the starch is prompted under a negative pressure condition so as to accelerate hydrolysis of the starch grains in an amorphous area. The method specifically comprises the following steps: homogenously crushing the starch grains under a pressure of 50-150 MPa, degreasing the crushed starch by using a 70-90% methanol-water solution, and accelerating hydrogen ions in sulfuric acid to rapidly penetrate into the starch grains to be subjected to restrictive hydrolysis under a 0.06-0.1MPa negative pressure condition, so as to prepare the nanocrystal. Through the technical measures, the hydrolysis period of the starch is shortened to be 48-72 hours, the starch nanocrystal yield is greatly improved to be 19-25%, and the particle size distribution is 20-300nm.

The present invention eliminates the need for power used for roll milling by significantly reducing the hardness of rice, and provides fine rice powder with good quality even when the rice is ground only with a jet mill. The present invention includes: a preprocessing step (5) of creating a number of fine cracks on the surface of an uncooked rice grain; a water-adding step (12) of increasing the water content of the rice grain having the fine cracks formed on the surface thereof; and a grinding step (19) of grinding, with a jet mill, the rice grain having absorbed water. That is, when water is added after the fine cracks are formed on the surface of the rice grain, the swelling of a compound starch grain proceeds remarkably faster than in the case of water being absorbed gradually through a germ. The rapid swelling increases the amount of strain in the structure of a cell wall, making it easy to break the strong structure of the cell wall and significantly reducing the hardness of the rice. At the time of grinding, due to the significant reduction in the hardness of the rice, the structure of the cell wall is easily broken and even a starch grain is finely ground.
