Abstract: A method is described comprising stunning a ruminant at a packing plant, and thereafter measuring tissue characteristics of the ruminant using a tissue imaging and analysis device prior to processing the ruminant to a carcass. Working embodiments of the method have used an ultrasound tissue imaging and analysis device, although other analyses also can be performed. The method can be used to, amongst other things, measure backfat and rib eye dimensions, obtain an ultrasound image, and determine rib eye area and marbling using the measured tissue characteristics. A method for processing and managing ruminants and ruminant products in feedlots and packing plants also is described comprising first measuring internal tissue characteristics and/or external body dimensions of ruminants at a feedlot. These ruminants are then fed at the feedlot, and then shipped to a packing plant where tissue characteristics of stunned ruminants are measured using a tissue imaging and analysis device.

Abstract: A computer-based system for providing up-to-date health histories of animals, for example, in a feedlot. The system includes indicia means associated with each animal for identifying the animal and data entry means coupled to a computer for reading the indicia means to identify the animal to the computer. The data entry means also communicates to the computer treatment data comprising the animal's physical condition and any treatment administered to the animal. The computer is programmed to record the identity and associated treatment data and collect the data with previous data to provide the animal's health history. The system also displays the identified animal's prior health history at the animal's location for the operator's benefit, which location is typically an animal hospital remote from the computer's location. The system may include a second data entry means for determining the net amount of drugs taken for animal treatment from an inventory.

Abstract: A highly automated method and system for providing individual animal electronic identification, measurement and value based management of cattle in a large cattle feedlot. Through the use of (1) a computer system integrated with (2) automatic individual animal identification (3) multiple measurement and remeasurement systems with automatic data input and (4) a cattle handling and sorting system, animals are individually (a) identified and (b) measured by weight, external dimensions and characteristics of internal body tissue. With this information together with animal physiological characteristics and historical data, the computer system calculates the optimum (c) slaughter weight, (d) economic end point and (e) marketing date for shipment to a packing plant. After measurement, individual animals are (f) sorted by direction of the computer in response to calculations from the measurements.

Abstract: A recycling system particularly useful for using, sorting and reusing large quantities of animal identification tags for use by producers, feedlots and packing plants is described. In one aspect of the invention, a plurality of unsorted, previously used and cleaned identification tags are passed through a tag aligner that aligns the tags in series. The aligned tags are fed to a tag sorter that includes a plurality of sorting bins for storing the sorted tags. A tag reader reads the identification tags and passes identification information stored on the tags to a controller. The controller analyzes the identification information from the tags and determines in which one of the sorting bins each tag should be stored. When each tag is adjacent the proper sorting bin, the controller signals the sorter to eject the tag into such bin. After sorting, the tags are redistributed to their original users for reuse.

Abstract: A method is described comprising stunning a ruminant at a packing plant, and thereafter measuring tissue characteristics of the ruminant using a tissue imaging and analysis device prior to processing the ruminant to a carcass. Working embodiments of the method have used an ultrasound tissue imaging and analysis device, although other analyses also can be performed. The ultrasound analysis can be performed by one operator, or plural operators. For example, if the device is an ultrasound tissue analysis device, the step of conveying may first comprise conveying the ruminant to a position adjacent a first operator. The first operator applies an ultrasound image enhancing fluid to the ruminant's hide, and a second operator places the ultrasound tissue analysis device adjacent the enhancing fluid and performs ultrasound tissue imaging and analysis on the ruminant.

Abstract: An automated tissue analysis system is described comprising a conveyor for delivering a feed animal to a tissue analysis zone, an ultrasound transducer designed to conduct tissue analysis on feed animals, and a remotely actuated positioner for placing the transducer on the feed animal. The ultrasound transducer is coupled to the positioner. One embodiment of the positioner comprises a saddle, a longitudinal slide frame, a dorsal/ventral slide frame and a pivot frame for accurately positioning the transducer on the animal for conducting tissue analysis. A transducer housing is provided that includes a built-in fluid passage and dispenser for dispensing conductive fluid onto the animal from a remote fluid reservoir. A fluid pump is fluidly coupled to both the reservoir and the dispenser in the transducer housing so that fluid can be pumped from the reservoir to the dispenser.

Abstract: Methods for maintaining and for preparing at a livestock feedlot a concentrated suspension of bacteria at a known, accurate concentration and for storing the prepared suspension for prolonged periods at the feedlot in a ready-to-use condition without significant loss of viability, allowing feedlot operators to conveniently administer such bacterial supplements to large numbers of livestock as a probiotic on a regular basis in accurate dosages. The method of administering the bacterial supplements includes, an insulated liquid-holding vessel cooled by refrigeration appliance, and mixing and recirculating appliances to ensure temperature and concentration homogeneity of the bacterial suspension. The vessel and contents are gravimetrically monitored to ensure accuracy of bacterial concentration.

Abstract: An apparatus for preparing at a livestock feedlot a concentrated suspension of anaerobic bacteria at a known, accurate concentration and for storing the prepared suspension for prolonged periods at the feedlot in a ready-to-use condition without significant loss of viability, allowing feedlot operators to conveniently administer such bacterial supplements to large numbers of livestock as a probiotic on a regular basis in accurate dosages.

Abstract: A method and apparatus whereby livestock and poultry are administered feed additives in their feed ration. The apparatus stores additive concentrates separately until just prior to use, then on demand dispenses the additive concentrates into one or more weigh hoppers for weighing therein. The weighed contents of the weigh hoppers are discharged into a liquid carrier within a mixing vessel where the dispensed additives are diluted, suspended, and dispersed by mixing. The resulting carrier-and-additive slurry is pumped to a receiving station for mixing with a feed ration. The weighing components are isolated from movements that would affect additive weight determinations during the weighing process so that accurate measurements of additive weights are obtained. Dispensing and weighing of multiple additives within a single weigh hopper are sequential. Each additive may be weighed and discharged from the hopper individually or cumulatively with other additives.
