577 Herd Production Medicine
Getting Connected to Information Pipelines
Version 3.3 Updated
The objective is to help students begin identifying and using sources of current
herd production medicine information, particularly
via the Internet, that they will need in practice to solve problems and
remove bottlenecks in client's
herds and to begin networking with innovative colleagues.
need efficient ways to keep up on developments in agricultural animal veterinary
medicine. Professional knowledge is constantly advancing, new diseases are
recognized or old ones emerge in a new form, technology is constantly evolving (e.g., ultrasound)
and the livestock industry changes rapidly because of the great economic
pressure of low margins and price volatility. This advancing knowledge may come from bench research, field
studies, collective practitioner experience or the allied industries and may
appear in the primary scientific literature, proceedings of professional
organizations, proceedings of trade meetings, trade publications, or industrial
sources. Because the need for an update on a given topic is most often driven by the
immediate need to solve a particular problem occurring in a
client's herd, the ability and means to do this both efficiently and timely is
very important. Now being available in the remotest of areas, the Internet
provides the most rapid access to information.
For the purposes of this class, the following is focused primarily on the bovine.
Books provide the fundamentals for approaching herd problems.
However, due to the time required for the writing and
publishing process, books are usually not current in all the areas they cover.
The fundamental core is a large animal medicine text, such as Blood and
Radostit's "Veterinary Medicine: A Textbook of the Diseases of Cattle,
Sheep, Pigs, Goats and Horses", Rebhun's "Diseases of Dairy
Cattle", or Smith's "Large Animal Internal Medicine".
Herd Production Medicine Texts:
The next level are those texts targeted specifically at
dealing with herd-level rather than individual problems.

From the Publisher: Herd Health offers integrated coverage
of all aspects of herd animals-dairy and beef cattle, calves, sheep, and
swine-in one volume. It provides effective new strategies for herd health
management. It gives veterinary students the basic knowledge and framework for
production-oriented animal health management and also gives veterinary
practitioners information to provide animal health management services to
every segment of the livestock industry. It integrates veterinary medicine,
animal husbandry, nutrition and housing, and animal welfare as they relate to
production management, acquaints veterinarians with economical programs that
allow for the most effective production of healthy livestock, resulting in the
best-quality food products, and offers an invaluable grasp of crucial issues
such as how to avoid contamination of meat and milk with antimicrobial
residues, antimicrobial-resistant bacteria, growth-enhancing hormones, and
other potential health hazards.

From the publisher: The main aim of this book is to
teach students, practitioners and farm advisors how to give management
support to the dairy farmer in order to optimize the health, productivity
and welfare of the herd. Management practices and farm conditions which
have both positive and negative influences on these aspects are covered,
rather than a more traditional focus on specific diseases. The core
element in this methodology is the protocol. In order to illustrate the
standard protocol the practitioner and farm advisor are taken through a
farm visit, during which operational and problem-solving issues are
addressed. These issues include: nutrition, health care, reproduction,
milk production, replacement rearing and farm economics.

Animal Husbandry and Management Texts:
Given that your "competition" (e.g., your
client's other information providers - feed company reps.,
pharmaceutical company reps., university extension personnel) often have at least
undergraduate training in animal science and that your clients expect you
to have at least the same level of understanding, you should be familiar with
the material in the capstone animal science courses for that industry.

For the purposes of this class, you are expected to complete the
following connection activities.
- Join the American Association of Bovine Practitioners as a student member
(students $15 / year).
Professional associations are one of the major ways that
practitioners keep up to date, to share ideas and to network with innovative
practitioners pushing the envelope of herd production medicine.
The AABP is an international association of
veterinarians organized to enhance the professional lives of its members
through relevant continuing education that will improve the well-being of
cattle and the economic success of their owners, increase awareness and
promote leadership for issues critical to cattle industries, and improve
opportunities for careers in bovine medicine. The AABP has a particularly
strong seminar series associated with their annual meeting. Annually the AABP
recognizes innovative beef and dairy practitioners who are widely esteemed by
their peers through sponsored awards at the national meeting.
The AABP has a page of topics and links for students at http://www.aabp.org/;

Join the Academy of
Veterinary Consultants as a student member. The AVC is an
association of veterinarians involved in beef cattle medicine, herd health
programs and consultation. The AVC mission is to provide continuing
education, member support and leadership among various entities of the beef
cattle industry. Membership in the AVMA is required.
To join as student member, contact Dr.
Dee Griffin 402-762-4500 and provide him information on your student
status, career intentions and so on.
If you have interests in other production species, such
as small ruminants or swine, you should join the respective professional
organizations for practitioners interested in those species.
- Sign on to AABP-L discussion list (requires membership
in AABP), set it to the digest mode and learn to use keywords to search the AABP-L archives.
E-mail discussion lists are a great way for practitioners to
exchange ideas and to obtain input on a problem in a client's herd from fellow
practitioners who have seen similar problems or from academicians doing
research in the area. This list is archived, meaning that you can search for
previous discussions on a particular subject.
For information on how to sign on to AABP-L, go to the AABP
website and click on "AABP Resources" then "AABP-L
List Server". For information on how to set AABP-L to the digest mode (to
avoid being buried by e-mails) and how to search the archives, click on "AABP-L
Help Area (for current subscribers)" at the top of the "AABP-L
List Server" page and read "Help, I have too many messages! -
Take the Digest Mode Cure".
- Subscribe to producer-oriented trade magazines in your area of interest:
For several reasons, subscribe to the trade magazines in your area of
interest. First, many new ideas are written up in trade
magazines before they appear in the professional refereed journals. These
ideas may not prove out but you need to know what innovations are being tried. Second,
trade magazines cover the economics of the industry, consumer trends and other
issues impacting your clients. The better you understand these issues, the
better you can tailor your services and understand client decisions. Finally,
because many of the articles are about diseases and animal health issues and
your clients expect you to be knowledgeable in these areas, you need to see what
your clients are reading about diseases
that you are dealing with in their herds. Many of these trade magazines have
websites as well.
For dairy (selected):
For beef (selected - free to qualified):
I recommend that you organize among yourselves, make a list of
addresses for all the people that want a particular magazine and have one
person make the contact. You will need to explain that you are veterinary
students intending to practice in this particular industry. You are not
limited to these particular trade magazines.
- Join American Dairy Science Association ($10/year) or American Animal
Science Association ($20/yr).
Given that many production medicine problems involve nutrition,
that feed is the single largest expense
and that animal science journals contain considerably more nutrition research than
veterinary journals, these journals are worthwhile to subscribe to. Student
membership allows access to the 1995 to date Journal of Dairy Science
or Journal of Animal Science articles as PDF files. On-line access to
the JDSA articles will be particularly useful during your senior Food

Excellent papers on important topics from national authorities.
Economic and Production Benchmarks:
Having economic and production benchmarks is very
important for you and your clients as they provide a basis for comparison
to identify areas of strength, weakness and opportunity. Benchmark
comparison between herds is a important motivator for top end producers.
for National Animal Health Surveillance (CNAHS)
USDA APHIS CNAHS regularly performs statistically
valid surveys of randomly selected livestock enterprises (e.g., beef
cow-calf, feedlot, dairy, swine) across the major states to determine
production losses, such as calf mortality, producer management practices,
such as transition cow management, health practices, such as what vaccines
producers actually used on what animals, and many other items. This is an
excellent source to determine what proportion of producers have adopted a
particular management practice advocated by veterinarians as well as
production and reproduction benchmarks. Click on a species in the top row
to view reports from all surveys dealing with that species or issue.
