The California DHIA is a federation of large herd local DHI associations located predominantly in California but also including parts of Nevada, Arizona, New Mexico, and Oregon. The California DHIA addresses the large herd perspective in matters related to dairy herd improvement nationally.

Traditionally among the DHI innovators, CDHIA has piloted such projects as the Verified Records Program, the lab sample comparison project, the electronic milk metering monitoring report, and most recently, the production string sampling method.  This backed by a strong program of monitoring Quality Certification parameters and effective communications.

The California DHIA provides highly qualified, friendly service to member organizations for a modest monthly fee based on the number of herds tested each month.
