Abstract

An improved 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) electronic or other automatic individual animal identification (3) multiple measurement and remeasurement systems with automatic data input means 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 physiological characteristics and historical data on the animals, 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. The computer system also calculates from the individual animal data and other data (g) each animal's pro rata share of the actual feed intake for the group with which it is being fed. The computer system (h) stores individual animal measurement, performance and location data, which is used by management to (i) select animals for shipment from the feedlot for slaughter at the optimum time. Following an animal's shipment to a slaughter facility, its identification in the computer system is used to (j) correlate the live animal physical characteristics and performance data to the measured and evaluated carcass characteristics data obtained during the slaughter process and (k) build a data base to more accurately identify and measure value based characteristics in subsequent animals produced and fed for more effective value based selection and management of those animals.
