CDCB-AJCA Genetic Evaluations



SITE NOTES, Tuesday, September 3, 2019:  The September monthly genomic reports are now available in PDF and excel files. 

Also posted is an article from CDCB explaining the changes coming in the fertility evaluations. What does this mean for Jerseys? You will likely notice changes in the DPR, CCR and HCR traits that are a result of modifications made by CDCB to stabilize and improve the accuracy of these evaluations. How does this impact JPI? DPR is included as 7% of the Jersey Performance Index (JPI). CCR and HCR are included at 2% each in JPI.

Changes in PTAs in fertility traits of Jerseys between the April 2019 and August 2019 runs WITH JPI IMPACT

CCR -1.63 -1.72 -2.10 -2.22
HCR -0.22 -0.33 -0.33 -0.50


A change in DPR of -0.61 equates to -2.92 JPI points. A change in CCR of -1.72 equates to -2.22 JPI points. A change in HCR of -0.33 equates to -0.50 JPI points. On average, the JPI of the April 2019 Genomic Tested Young Sires decreased by about 6 JPI points with their August 2019 evaluations. Individuals may be impacted to a greater or lesser degree.  



NEW WEBINAR POSTED:  On April 12, 2019, AJCA staff discussed the new genetic summaries with the first multi-breed evaluations in this webinar.


AJCA BOARD ACTIONS REPORTED:  The November meetings of the AJCA and NAJ Boards of Directors are reported on Actions include new registration rules for Generation Count and JX males; naming and genetic evaluations for animals that have UR (unregistered) status; to remove Jersey Haplotype 2 (JH2); to recognize Holstein haplotypes affecting fertility; and adoption of budgets for 2019.
