QC Metrics for Genomic Nominators¶
The performance metrics constitute the quality control standards that the CDCB expects nominators to meet. Certification status can be promoted/demoted from current status based on the periodic performance review. Nominators can review their performance in a monthly report card which includes their performance statistics.
The following list indicates the report card metrics and descriptions. It also shows thresholds to determine if your submission succeed/failed for each metric.
No nomination when loading¶
- Number of genotypes missing a nomination when loaded. Nominators are required to submit a nomination for each animal whose genotype will be submitted to the CDCB database (including the animal pedigree if it is not yet in the CDCB database), since the information must be present when the genotype arrives from the lab. Please see Metrics section on the Quality Certification Requirements for Genomic Nominators
Unknown animal ID¶
- Number of genotypes with unknown animal identification(ID) or the genotype conflicts with another genotype assigned to the same animal, so it has been assigned a negative key. This occurs when the animal has not been nominated and the genotype submission is missing the animal ID or the animal ID has not been entered in the CDCB database.
IDs with 573/574 (OBSOLETE) This will only continue to apply to Zoetis¶
- Number of genotypes having animal IDs with American ID numbers beginning with "000 057 3” or "000 057 4”. IDs in this range are assigned only by those authorized to use this range and typically these IDs are not attached to the animal. The preferred solution is to identify the animal by a tag attached to itself.
CDCB blanked dams due to conflict¶
- The nominator provided the dam information, but it was rejected and not stored due to a conflict.
Common reasons for CDCB blanking are:
- Animal birth date does not agree with dams calving date
- A maternal sibling has a birth date within 9 months of the animal submitted.
Note: These checks are bypassed for embryo transfer genotypes.
Usability code = N¶
- Number of genotypes with conflicts, preventing the genotype from being usable for genomic evaluation purposes. This count includes only those cases that have not been corrected at the time the report was created.
Fee code = N¶
- Number of genotypes with genomic fee code N
Most common causes are:
- No fee code was assigned to the individual, therefore it remains with the default value N
- A fee code N was intentionally assigned to the individual
- Number of genotypes that were withdrawn during the reference month. The withdrawal is appropriate only for unusual cases in which the genotype is not expected to ever become usable (e.g. submission of genotype not intended for CDCB, non dairy cattle genotype, etc.)
- Genotypes reassigned to a new animal due to an incorrect initial assignment.
Changes in pedigree¶
- Changes in the pedigree of the animal that occurred during the reference month.
Sire pedigree missing¶
- This metric counts genotypes without pedigree information of the corresponding sire ID in the CDCB database.
This can occur when:
- The sire ID is invalid
- A herd bull is not registered in a breed association
- A foreign bull pedigree has not been provided.
Dam pedigree missing¶
- This metric includes genotypes without pedigree information of the corresponding dam ID in the CDCB database. Unfortunately, this information is not always available on the farm. A high value in this metric may suggest that additional work with customers is needed.
Herd reason codes (HRC)¶
- Represents the number of cases in which Herd difference reason code (HRC) has been used.
Nomination Fee Codes Changed¶
- Number of changes in Nomination Fee Codes
