Of those records that failed, 76.1 percent lacked proper sire identification. Although herd owners and DHIA supervisors are responsible primarily for accuracy and completeness of input data, DRPC's, DHIA management, Extension and AIPL share responsibility for enhancing the process. Each processing center has its own unique way of correcting conflicts in the data and furnishing missing data. In March and September, the AIPL runs semiannual miniruns. These are an effort to detect identification errors before the lactation is completed.
Some centers attempt to correct information when a duplicate identification is detected.
These centers send checklists to supervisors that have cows with conflicting registration or eartag numbers. Only cows with sire identifications on file are included on the list. To correct identification, the supervisor should do the following. The other cow involved in the duplication may or may not be in the same herd. She could be in another herd or even another state.
