A method for selectively enhancing animal feed by the addition of feed supplements to raw materials in accordance with a determination of the improvement in homogeneity of the physiological response of animals fed with the feedstuff. Batches of raw material for the feedstuff which have a nutritional value below a threshold are supplemented with a feed supplement, whereas batches already high in nutritional value are not supplemented. This reduces the variance in nutritional value of the feedstuff, and improves homogeneity in the physiological response of the animals to the feedstuff. The nutritional value is measured in terms of the amino acid content, and the feed supplement is an enzyme which improves the digestibility of the amino acid. |
