Board Elections

In the recent election conducted by mail-in
ballot, Mark Rodgers, Dale Eade and Gary
Keyes were reelected to the Board. Nine
dairy farmers make up the Board of
Southeast DHIA. These persons spend
valuable time guiding and overseeing the
DHIA program in Florida and Georgia. The
next board meeting is set for mid-January.

Revised Requirements for Recognition

Recognition of high herd production has
been a traditional part of DHIA. While it is
far from the highest priority use of DHIA
data, production recognition continues to be
important to many. Several years ago,
National DHIA gave up the definition of
requirements to the end users. Southeast
DHIA was asked to recommend minimum
requirements for use in our area. The SE
DHIA Board has adopted new requirements
for production recognition. Herds will need
a minimum of 9 DHIA tests days and no test
interval greater than 65 days

Technician Evaluations

Some time ago, DHIA changed from the
term DHIA Supervisor to DHIA Technician.
While DHIA Technicians still supervise the
test-day and provide certification of cow
identity and milk production, the job
description includes much more. Each year,
DHIA Technicians are evaluated for
performance. A part of that evaluation is a
survey of herdowners serviced by each
Technician. Enclosed with this newsletter is
a response card for this purpose. Please take
a minute to provide a response that indicates
your opinion of the performance of your
DHIA Technician.


DHIA Provides Good Reproductive Analysis

Herds on DHIA have receive comprehensive
summary of their herd's reproductive
performance each test-day. The profile of
reproduction can be used to target areas of
management that need attention for
improved profit. In recent months, Herd
Pregnancy Rate has been added to the
information summarized on the DHIA Herd
Summary (DHI-202 form) provided by
DRMS. This calculation is reported to be
the best index of overall reproductive status
of a herd. Take a look at these numbers for
your herd and see what it tells you.

Georgia Milk Producers' Meeting

This year's meeting will be January 27 and 28 in
Perry. Southeast DHIA will have a booth.
