Interpretive Summary: The Animal Improvements Programs Laboratory assumed responsibility for conducting the national genetic evaluation for calving difficulty (dystocia) and maintaining the associated database in 1999. The dystocia data were migrated to a relational database that is integrated with the AIPL national database of production data including lactations and pedigree back to 1960. A major goal of this effort was to increase the maternal grandsire (MGS) identification (ID) rate by utilizing production pedigree information. Nearly 70% of the dam ID could be matched to the production pedigree table. By integrating pedigree information from production data, the rate of MGS ID was increased from 57 to 73%.
