CDCB Health Traits

In April 2018, CDCB launched genetic and genomic evaluations for Holstein males and females, for six of the most common and costly health events impacting dairy herds.

These new predicted transmitting abilities (PTAs) are presented as percentage points of resistance above or below the breed average. Larger, positive values are favorable.

There are no changes to the net merit index in April 2018. Development of a health-enhanced net merit is expected in the future (date to be determined).

These resources are available to help dairy producers and industry personnel understand the new CDCB health traits.
