Abstract: A mixer/feeder wagon (1) for mixing and dispensing batches of animal feed comprises a device (50) for monitoring operation of the mixer/feeder wagon (1) and for determining instants during a mixing cycle during which ingredients of the animal feed are to be loaded into the mixer/feeder wagon (1). The mixer/feeder wagon (1) comprises a mixing compartment (14) within which a paddle mixer (17) is rotatable for mixing the ingredients of the batch of animal feed therein. Load sensors (9) produce signals indicative of the current weight of the ingredients in the mixing compartment (14) which are read by a microprocessor (55) of the device (50). A proximity sensor (38) counts the number of revolutions of the paddle mixer 17.

Abstract: A method and apparatus for determining a mixing regime for use in the preparation of an animal feed in which a main computer is programmed to store a master list of ingredients which are available to farmers and from which a farmer can select a specific set of ingredients for the preparation of animal feed. The main computer is programmed to store the ingredients in a look-up table cross-referenced with standard mixing periods to which the respective ingredients should be subjected during the mixing regime to produce an animal feed. Additionally, the look-up table contains mixing factors by which the standard mixing periods may be altered in order to take account of non-standard conditions, such as variations of the ingredients, the proportion of the particular ingredient, the average size or weight of the animals and the mixing apparatus and condition thereof in which the animal feed is to be mixed.

Abstract: 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 I00 gms to 550 gms per kg prepared feed. The digestion enhancing forage material of the prepared feed comprises fibres of length in the range of 30 mm to 50 mm and has a primary saturation extent in the range of the order of 680 mls to 820 mls water per litre of digestion enhancing forage material, an uncompressed specific gravity of the order of I 00 gms to 220 gms per litre and a first compression specific gravity of the order of 140 gms to 290 gms per litre and a second compression specific gravity of the order of 150 gms to 500 gms per litre.

Abstract: A batch of animal feed from a plurality of ingredients is prepared in a mixer/feeder wagon (1) where the ingredients require respective predefined mixing periods during a mixing cycle in the mixer/feeder wagon (1). The mixer/feeder wagon (1) comprises a mixing compartment (14) in which a mixing rotor provided by a paddle mixer (17) is rotatably mounted. Stationary chopping blades (42) mounted in a base (43) of the mixing compartment (14) cooperate with the paddle mixer (17) for chopping fibrous material during the mixing cycle. The appropriate predefined mixing periods required for the respective ingredients are determined in order to avoid over-mixing and under-mixing of the ingredients, and the predefined mixing period is defined as the number of revolutions of the paddle mixer (17) to which that ingredient is to be subjected.
