<p><P>PROBLEM TO BE SOLVED: To provide a livestock product tracking system capable of actively tracking livestock products. <P>SOLUTION: A process management database 25 stores records including a manufacturing process name with which a livestock product is manufactured, a manufacturing time when the livestock product is manufactured, a material process name with which the livestock should be used as materials and a use time when the livestock product is used for each livestock product. A CPU 11 specifies a record wherein a manufacturing process name shows a process in which a particular livestock individual is raised and a manufacturing time includes a time when the livestock individual is raised as a processing target record on the basis of the process and the time. Then, the CPU 11 performs a tracking subroutine which specifies a record having a manufacturing process name that coincides with a material process name in the processing target record and a manufacturing time included in a use time in the record as a new processing target record until a processing target record can not be specified any more. <P>COPYRIGHT: (C)2004,JPO</p> |
