5. ID and Cross Ref – ITB 03.06 (5)G.R. Wiggans and P.M. VanRaden 20042006 How invalid ID’s are detected  CAN provides all valid ID’s – Used to correct country code  Detect similar ID 1 digit difference, and shifts – old ID replaced  USA or CAN ID not already present in domestic tables

6. ID and Cross Ref – ITB 03.06 (6)G.R. Wiggans and P.M. VanRaden 20042006 Interbull data integrated with domestic data  Allows calculation of Net Merit for all bulls  Allows calculation of parent averages for use where evaluations are missing  Same edit checks applied to domestic and Interbull ID’s and pedigree

7. ID and Cross Ref – ITB 03.06 (7)G.R. Wiggans and P.M. VanRaden 20042006 Processing Interbull pedigree  Pedigree and aliases stored in keyed access tables of just Interbull  Records from authoritative source added to domestic pedigree tables  Pedigree added for non-USA bulls with evaluations Web source if CAN or GBR  Table of primary Interbull ID’s maintained to identify international ID

13. ID and Cross Ref – ITB 03.06 (13)G.R. Wiggans and P.M. VanRaden 20042006 Normal edits  Match birth date with dam’s calving  Compare with other sources (e.g. breed association)  Investigate maternal sibs born within 9 mo (may assume ET)  ID’s within 100 with same sire, dam, and birth assumed to be twins

14. ID and Cross Ref – ITB 03.06 (14)G.R. Wiggans and P.M. VanRaden 20042006 Normal edits cont.  Require reasonable intervals between birth dates of parents and progeny 18 mo to 18 yrs  Internal animal key assigned  All ID’s with same key are aliases  Preferred ID designated

15. ID and Cross Ref – ITB 03.06 (15)G.R. Wiggans and P.M. VanRaden 20042006 Problems  Missing birth date of dams  Missing twin or ET designation  Breed codes not same on all occurrences of animal (Better in Feb)  IDs reported as invalid continue to be submitted  IJE Country code; FH0 breed code

16. ID and Cross Ref – ITB 03.06 (16)G.R. Wiggans and P.M. VanRaden 20042006 Problems cont.  International ID not accepted by US industry for all bulls  Resistance to change bull ID once he has been marketed  More than 1 evaluation for bull because of missing cross reference or ID error  Retain one with highest reliability

17. ID and Cross Ref – ITB 03.06 (17)G.R. Wiggans and P.M. VanRaden 20042006 Proposals  Provide birth dates of bull dams  Provide twin or ET designation  Prevent invalid ID’s from appearing in Interbull output files (i.e. reject records of such bulls)  Facilitate sharing of pedigree data between countries
