In July we became aware of a new genetic recessive trait with economic significance called HCD (Haplotype Cholesterol Deficiency) which in animals carrying both copies of the recessive gene means eventual death during calfhood. Since the discovery, the University of Liège in Belgium has identified the gene mutation responsible for the genetic defect. With knowledge about the haplotype and a list of known carriers, the researchers were able to identify the corresponding causative mutation. The discovery means that animals can now be tested to determine whether they are a carrier with a reliability of 100%. It’s an important step in reducing the incidence of this – still recently discovered – genetic defect.

WestGen has chosen to identify HCD carriers in its marketing materials to assist producers with their sire selection choices.
