CDCB and USDA Animal Genomics and Improvement Laboratory
November 16, 2023
Changes for the December 5, 2023, CDCB evaluations include updated imputation results for all breeds, new haplotype calls for early onset muscle weakness syndrome in Holsteins, and update to the haplotype calls for cholesterol deficiency in Holsteins.
Researchers at Penn State University have been collaborating with colleagues at USDA’s Agricultural Research Service to study a new genetic defect in Holstein cattle. This defect is characterized by otherwise healthy animals that are unable to stand. This condition, currently called calf recumbency, has proven to be more complex than other known genetic defects.
BH14 has been added to the list of genomic haplotypes reported in the U.S., following USDA AGIL analysis of records in the CDCB database. Routine publication of BH14 status will support breed fertility improvement by allowing appropriate selection and mating of males and females.
Accreditation for Parentage Verification Extended by ICAR
February 10, 2023
CDCB has been re-accredited as a DNA Data Interpretation Center for parentage verification by ICAR. This certification is part of CDCB’s service to U.S.-based genomic nominators and facilitates the export of U.S. genetics.
