摘要：
A prepared feed for a ruminant is produced by mixing a plurality of ingredients, at least one of which is a forage material. At least some of the forage material acts to enhance digestion of the prepared feed by the ruminant. The digestion enhancing forage material typically comprises one or more of hay, straw, silage and other stalky material, and constitutes in the range of I00gms to 550gms per kg prepared feed. The digestion enhancing forage material of the prepared feed comprises fibres of length in the range of 30mm to 50mm and has a primary saturation extent in the range of the order of 680mls to 820mls water per litre of digestion enhancing forage material, an uncompressed specific gravity of the order of I 00gms to 220gms per litre and a first compression specific gravity of the order of 140gms to 290gms per litre and a second compression specific gravity of the order of 150gms to 500gms per litre. This produces a prepared feed of primary saturation extent in the range of 675mls to 735mls water per litre of prepared feed, an uncompressed specific gravity in the range of 200gms to 280gms per litre, a first compression specific gravity in the range of 180gms to 300gms per litre and a second compression specific gravity in the range of 270gms to 430gms per litre. The first and second compression specific gravities are determined by subjecting the digestion enhancing forage material and the prepared feed to respective first and second downward forces of 2.41 kg and 7.41kg in a vertical cylindrical container of diameter of 75mm. The digestion enhancing forage material forms a uniform homogenous low density open matrix which extends throughout the rumen liquor within the rumen with particulate and other nutritional ingredients as well as other forage material dispersed throughout the matrix and retained therein for optimising the dwell time of the nutritional and other fibrous ingredients within the rumen for in turn maximising the production of intermediary produ
