PDF files are coming to DHIA

PDF is the acronym for portable data
format. These files are "read only" and can be
used to provide information in a form that will
remain in tact while being printed and viewed by
PDF files are the proprietary product of
Adobe, a software company that specializes in
graphics and document editing. One of their
products, Adobe Acrobat ReaderC is required to
view or print PDF files. This reader is readily
available on numerous web sites and is
distributed with PCDART-7 for windows.
One of the primary advantages of PDF
files is their "portability" in that they view and
print nicely on any Microsoft WindowsO system
where video and printer hardware are properly
installed. DHIA uses pdf files as follows:

1. DRMS will soon be providing DHIA
forms in PDF via email.
2. PCDART version 7.5 will allow reports
to be saved as PDF's.
3. Southeast DHIA will be distributing
forms, newsletters and other stuff via
PDF files.
We hope that this discussion of PDF will
allow you to become familiar with this
technology to assist with your DHIA

DHIA Reports By Email
Web Reports is an option that will
enable producers and consultants to access
DHIA reports via the web. Traditional herd
report files will be converted to PDF files. You
will be notified via email when reports are
available. The most recent 2 years of the Herd
Summary (202) and the most recent 3 months of
all other reports chosen will be accessible. Mail
turn-around is eliminated and PDFs can be
printed on most standard printers. To preview
this option, try the DRMS web site at Direct your questions to the
Southeast DHIA office (352-392-5592) or email

Version 7.5 of PCDART will be
available later this spring! This new release will
include a number of enhancements and some
new features. Enhancements will include
improved speed of report retrieval, better
compatibility with Windows XP, additional
flexibility for data input and more efficient
synchronization with Palm computers. One
important new feature will be the expanded
protocol for using various timed AI programs.
Another advancement will provide a new
interface with various automated milk recording
systems. While all DOS functions will continue
to be available, DRMS's Director of Program
Development, Phil Dukas says that most users
will prefer the Windows apps. Field-testing is
under way. You can get an early look at version
7.5 at a special session in Reno on March 14.

What is Standardized 150-day Milk?

Standardized 150-day milk is the
expected production per day at 150 days in milk.
It removes the variation in test day production
due to stage of lactation and it allows production
on one test day to be compared to production on
another test day. Thirty-six standard lactation
curves based upon six seasons, three ages and
two breed groups are used to either project
forward or backward to 150 days in milk. In
order to allow one to compare the production at
150 days for different cows, the values are also
adjusted for age and breed. The standard curves
were established for:

1. Six seasons: Jan-Feb, Mar-Jun, Jul-Aug,
Sep-Oct and Nov-Dec
2. Three ages: first lactation, second
lactation and third or more lactations
3. Two breed groups: Ayrshire-Brown
Swiss-Holstein and Guemsey-Jersey

Standardized 150-day milk is the best
single number to compare your herd's
production from month to month.

PCDART 7.5 on the Horizon

NDHIA Code of Ethics

Several years ago, DHIA in the U.S. changed its concept from that of official rules to one of
standard procedures. At the same time, the Code of Ethics was formulated to provide guidance about
certain aspects of conduct in producing milk production records for the dairy industry. NDHIA's Uniform
Operating Procedures define the methods used in DHIA and the Code of Ethics defines appropriate
conduct of persons involved. The following is taken directly from the NDHIA document.


This Code ofEthics provides guidelines for appropriate conduct in the production, collection, and
distribution of DHIA information for all persons involved with these records.


A. Impairing the reliability ofDHIA information.

B. Not (., 'y, i, lg fully or interfering in use of the uniform data collection procedures to record DHLA

C. Intentionally providing inaccurate information to, or i ,llb ', ir necessary information, from

D. Engaging in management pti IL I L with the intent of misrepresenting the performance of individual
animals or the herd. Among these p, it L // L % is the qI ii 'i ,tI/I movement of animals between herds,
influencing the relative performance ofherdmates, and selective use of management techniques in an
effort to bias the DHIA record. Management pt, iL /I ,L on test day should be 1 Lj L ML i11/ IL of typical
pi L iL L used on other days.

E. PL I ilmi ig the collection ofsupervised data by a technician with a directfinancial or family interest
in the herd being tested.

F. Any faudulent or unethical practice defined by the Board ofDirectors ofNational DHIA.

G. Incomplete release ofproduction data 1 L killing in 11,11 11 L %\L l,,, ,i of DHIA information.

The tone of this document is clear. Any action by herd owners/managers or DHIA personnel,
which serves to misrepresent or overstate the performance of a cow or herd, is unethical.

Lab Hot Sheets by Email

Herds receiving DHIA somatic cell
counts (SCC) can receive a "hot sheet", direct
from the lab immediately after lab work is
completed. This list shows SCC and lab results
for all milking cows and a list of the 20 cows
contributing most to the herd's average cell
count. In the past, this document has been
available only by mail or fax. Now you can
receive it by email. Just tell your DHIA
Technician and provide your email address on
the paperwork that goes to the lab. The lab will
need your DHIA herdcode number and email
address. (dww 2-10-03)

Meter Calibrations Required

One of the most important aspects of
DHIA service is accuracy of meters. Without
some assurance that the milk weights are
accurate, we don't have much. DHIA operating
procedures call for annual calibration checks of
all meters and scales providing data for DHIA.
Meters provided by Southeast DHIA, Inc. are
carefully calibrated annually and at any
additional time as requested by the technician or
when any major repairs are made. Meters owned
and provided by dairymen are subject to annual
calibration checks. Don Shaw, the
SOUTHEAST DHIA meter-man, can calibrate
portable meters such as TruTest or Waikato. SE
DHIA has an approved meter calibration facility
and Don is a certified meter technician.
Dairymen with portable meters are encouraged
to contact Don to arrange for calibration of their
meters. Dairymen using electronic meters should
contact their milking equipment service for
official calibration.

In either case, SEDHIA is asked to report the
calibration status of all meters used in DHIA.
We do this annually as a part of the Quality
Certification process.
