After a week’s delay due to a data submission error, the April 2022 U.S. genetic evaluations are now officially available. This information replaces the data originally released last week on April 5.
That release mistakenly utilized data from December 2021 for Holstein bulls. Other breeds were not affected. The error significantly affected the Predicted Transmitting Abilities (PTAs) of recently classified cows, genomic evaluations for bulls that added many newly classified daughters, and their descendants, said the Council on Dairy Cattle Breeding (CDCB). The correct data has now been processed.
A few important trait updates were implemented for this month’s proof run. Read about the changes and their expected impacts from CDCB here.
Additionally, this month’s triannual genetic evaluation is the first since the national cooperator database reached 6 million genotypes on February 19, 2022. Although it took seven years for the first 1 million genotypes to be recorded, in recent years 1 million records are being added about every 12 months.
By the numbers
A.I. organizations reported 5,767 bulls active in April, 3,933 of which were genomic young bulls. This gives genomic sires a 59% market share, which is down from the 68% they held in both the December and August 2021 runs. Holstein sires numbered 4,685 in all, and 794 Jersey bulls were included in the total.
You can access the full sire rankings for genomic and proven bulls of all breeds now.
