A highly automated system of measuring and managing individual animals in a grazing animal production environment comprising: a transmitter is one of attached, implanted and ingested on or by a particular animal which identifies the particular animal by a unique signal, a measurement unit (8, 8') on which measurement devices are mounted, the measurement unit (8, 8') comprising: a receiving device that receives the unique signal from the transmitter, a weighing device that measures a partial body weight of the animal, a consumption dispensing station that supplies substances to the specific animals, a microprocessor that receives, processes and transmits and controls signals from devices attached to the measurement unit (8, 8'), a communication device (18A, 18B) that receives and transmits signals from the measurement unit (8, 8') to other measurement units (8, 8'), and at least one of locally and remotely positioned computers via at least one of local, satellite, cellular and Internet communication networks, the computer that is local or remotely situated and receives the signals and which also collects measurements from other devices and uses statistical methods, mathematical formulas, and algorithms to estimate, calculate, predict, monitor, evaluate, store and reevaluate animal, plant, soil, environment, operation and industry values, metrics, parameters and interactions with degrees of confidence, and the consumption dispensing station being variably actuatable by the computer to supply variable formulations and amounts of the substances to the particular animal currently located at the measurement unit (8, 8') based on the values, the metrics, the parameters and the interactions. a transmitter is one of attached, implanted and ingested on or by a particular animal which identifies the particular animal by a unique signal, a measurement unit (8, 8') on which measurement devices are mounted, the measurement unit (8, 8') comprising: a receiving device that receives the unique signal from the transmitter, a weighing device that measures a partial body weight of the animal, a consumption dispensing station that supplies substances to the specific animals, a receiving device that receives the unique signal from the transmitter, a weighing device that measures a partial body weight of the animal, a consumption dispensing station that supplies substances to the specific animals, a microprocessor that receives, processes and transmits and controls signals from devices attached to the measurement unit (8, 8'), a communication device (18A, 18B) that receives and transmits signals from the measurement unit (8, 8') to other measurement units (8, 8'), and at least one of locally and remotely positioned computers via at least one of local, satellite, cellular and Internet communication networks, the computer that is local or remotely situated and receives the signals and which also collects measurements from other devices and uses statistical methods, mathematical formulas, and algorithms to estimate, calculate, predict, monitor, evaluate, store and reevaluate animal, plant, soil, environment, operation and industry values, metrics, parameters and interactions with degrees of confidence, and the consumption dispensing station being variably actuatable by the computer to supply variable formulations and amounts of the substances to the particular animal currently located at the measurement unit (8, 8') based on the values, the metrics, the parameters and the interactions.
