A system and method are provided for administering micro-ingredient feed additives or supplements to feed rations. The amount of each particular micro-ingredient to be delivered to a feed ration may be determined by a bulk density measurement. Alternatively, bulk density measurement may be used in combination with existing weight measurement and volumetric metering methods for multiple micro-ingredients. Delivery by bulk density requires determination of a bulk density value along with use of a dispensing device that dispenses a calculated amount of the micro-ingredient ration. The dispensing calculation may be achieved by analysis of delivery time, pulse count, or some other quantitative measure such as magnitude. Use of bulk density as a measurement technique eliminates the requirement for use of scales in the micro-ingredient delivery system.

What is claimed is: 1. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of: determining a bulk density for at least one micro-ingredient; assigning a base value to the bulk density; dispensing the micro-ingredient from a dispensing device; recording the length of time in which the dispensing device operated to dispense the micro-ingredient; calculating an amount of the micro-ingredient delivered taking into account the bulk density value and the length of time; determining a compensation factor without weighing the micro-ingredient, said compensation factor being derived from consideration of at least one factor of a plurality of factors including temperature, viscosity, and loose/hard packed packaging and storage conditions; adjusting the base value of the bulk density by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value and the length of time. 2. A method, as claimed in claim 1, wherein: said dispensing step is achieved by use of at least one of an auger and a pump. 3. A method, as claimed in claim 1, further comprising the step of: validating the bulk density value by comparing the calculated amount of the micro-ingredient dispensed to a weight of the micro-ingredient dispensed. 4. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of: determining a bulk density for at least one micro-ingredient; assigning a base value to the bulk density; dispensing the micro-ingredient from a dispensing device; recording dispensing of the micro-ingredient, said recording being a count of units; calculating a revised amount of the micro-ingredient delivered taking into account the bulk density value and the recorded units; and determining a compensation factor without weighing the micro-ingredient, said compensation factor being derived from a calculation of at least one factor of a plurality of factors including temperature, viscosity, and loose/hard packed packaging and storage conditions; adjusting the base value of the bulk density by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value and the recorded units. 5. A method, as claimed in claim 4, wherein: said recorded units comprise pulse counts. 6. A method, as claimed in claim 4, wherein: said dispensing step is achieved by use of at least one of an auger and a pump. 7. A method, as claimed in claim 4, wherein said recording step is achieved by use of at least one of a flow meter and a sensor. 8. A method, as claimed in claim 7, wherein said sensor includes at least one of a capacitive sensor, an inductive sensor, and a laser sensor. 9. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of: determining a bulk density for at least one micro-ingredient; assigning a base value to the bulk density; dispensing the micro-ingredient from a dispensing device; recording dispensing of the micro-ingredient, said recording being a count of units; calculating an amount of the micro-ingredient delivered taking into account the bulk density value and the recorded units; and validating the adjusted bulk density value by comparing the calculated amount of the micro-ingredient dispensed to a volume of the micro-ingredient dispensed. 10. A method of measuring micro-ingredients delivered to a feed ration, said method comprising the steps of: determining a bulk density for at least one micro-ingredient; assigning a base value to the bulk density; dispensing the micro-ingredient from a dispensing device; sensing the micro-ingredient as it is dispensed; calculating an amount of the micro-ingredient delivered taking into account the base value of the bulk density and a signal generated in response to the sensing step; and determining a compensation factor without weighing the micro-ingredient, said compensation factor being derived from consideration of at least one factor of a plurality of factors including temperature, viscosity, and loose/hard packed packaging and storage conditions; adjusting the base value of the bulk density by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value. 11. A method, as claimed in claim 10, wherein: said sensing step incorporates a laser sensor to provide said signal, said signal being used to correlate a volume of the micro-ingredient to an amount of the micro-ingredient delivered. 12. A method of measuring micro-ingredients delivered to a feed ration, said method comprising: determining a bulk density of at least one micro-ingredient; assigning a base value to the bulk density; dispensing the micro-ingredient from a dispensing device; determining an amount of the micro-ingredient delivered taking into account the base bulk density value; determining a compensation factor, said compensation factor being derived from a consideration of a boundary layer comprising at least two different micro-ingredients and without weighing the micro-ingredients; adjusting the base bulk density value by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value. 13. A method of measuring micro-ingredients delivered to a feed ration, said method comprising: determining a bulk density of at least one micro-ingredient; assigning a base value to the bulk density; dispensing the micro-ingredient from a dispensing device; determining an amount of the micro-ingredient delivered taking into account of the bulk density value; determining a compensation factor, said compensation being derived from a consideration of proportional amounts of at least two different liquid micro-ingredients and without weighing the micro-ingredients; adjusting a base value of the bulk density by the compensation factor; and calculating a revised amount of the micro-ingredient delivered taking into account the adjusted bulk density value.
