Abstract: Improved feedstuffs and methods for obtaining them. One embodiment relates to the selection of a feedstuff for use in an animal feed, and enhancing batches of the feedstuff with one or more nutrients to obtain an improved feedstuff. Other embodiments of the invention relate to the improved feedstuff, an animal feed comprising the feedstuff, and a method of feeding an animal with the feedstuff. The improved feedstuff possesses consistent, desired levels of nutrients with a lower than natural variance in those levels.

Abstract: A method of selecting and enhancing of feedstuffs for use in an animal feed product by analyzing the statistical distribution of the nutritional content of batches of the feedstuff and calculating the number of batches within a predetermined range of a desirable nutrient composition. The cost of enhancing the feedstuff by adding nutrient additives is calculated and batches of the feedstuff are accepted or rejected, with the enhancement step only applied to the accepted batches. The method can be applied to products such as soyabean meal and corn which are major constituents of animal feed. It produces a feedstuff with a lower than natural variance in nutrient composition and a guarantee of a desired nutritional composition without the need for systematic overformulation of the product.
