The Data Integrity report is a useful tool to improve plan accuracy. To quickly identify missing or incomplete animal data, download the Data Integrity Report from the Genetic Dashboard. For the most accurate and comprehensive herd analysis, be sure to add parentage details for the animals in your herd. VAS recommends adding the data for all animals for the following standard PULSE/DairyComp 305 items:
- Sire ()
- Dam ()
- Maternal grandsire (MGS)
- Maternal great-grandsire (MGGS)
This data is used to assess the herd's genomic profile and is the basis of calculations made for specific animal traits and potential improvements.
The breed average is also incorporated into the assessment calculations, but having specific parentage data for the animals in your herd greatly increases the accuracy of the analysis process:
- Three-generation parent average: If a proof is not available for a female, trait data is used from three previous sire generations (sire, maternal grandsire, and maternal great-grandsire) to calculate the female's trait averages. Alta BLUE LINK calculates the trait values using weighted percentages of the three-generation parent averages and the breed average:
- 50% sire
- 25% maternal grandsire
- 12.5% maternal great-grandsire
- 12.5% breed average
- One-generation parent average: To calculate a potential progeny's trait averages, trait data is used from the progeny's parents (sire and dam).
- Breed average: When parent data is unavailable, a progeny's trait averages are based on the breed average.
