seeking advice from
the University of
Florida's Institute of
Food and
Agricultural Sciences
and the Florida
Extension Service
can get it fast from
the IFAS-Extension
Bookstore's 2001
catalog and
redesigned Web site.

"In response to public demand, we're
making our products more accessible to customers
outside the Gainesville area," said Eva Squires,
marketing coordinator for the IFAS-Extension
Bookstore. "We've also simplified the ordering

Squires said the catalog and Web site offer
more than 200 books, videotapes, computer
software items and other resources, many of them
updated for 2001. The catalog will be available in
early June; the Web site is already functional.

To aid customers, the catalog and Web site
are organized identically. All resources are
grouped into topics, including agriculture,
education, fruits and vegetables, home and
community, landscape and lawns, natural
resources and wildlife, livestock and poultry,
pesticide training and management guides, she

"We redesigned the Web site for easier
use," she said. "Every product is accessible with a
maximum of three mouse clicks. We tried to make
the site equally convenient for customers seeking
a specific item, and those who want to browse."

Squires said both the Web site and catalog
will be supplemented as new items become
available. Customers can request to receive
product updates by e-mail.

To help customers select resources to meet
their needs, IFAS-Extension Bookstore
representatives can answer questions by telephone.
Five ordering options are available, including
secure online credit card ordering with same-day
shipping, she said.

"Many of our customers requested online
credit card ordering because it's so much faster,
and we're very pleased to have it now," Squires
said. "We accept VISA and MasterCard."

Some IFAS-Extension Bookstore resources
are available from other distributors, she said.
Most major retailers can order out-of-stock
IFAS-Extension products using International
Standard Book Numbering (ISBN) identification

"We believe IFAS-Extension Bookstore
products offer Florida residents the best possible
value," Squires said. "They're developed from
research by UF and extension scientists."

She said IFAS-Extension Bookstore
products demonstrate the partnership between UF
research and extension.

"Together, we find out what works for
Florida," she said. "Extension helps researchers
understand what the public needs, researchers help
extension provide solutions for the public. It's a
winning combination."

Squires said extension services throughout
the Southeast look to UF for innovative programs
and products.

"We get phone inquiries all the time from
extension personnel who have seen our
publications and want to adapt them for their own
states," she said. "It's great to know our work is
well-regarded outside of Florida."

The U.S. Department of
Agriculture (USDA) continues to be vigilant in its
efforts to prevent the introduction of
foot-and-mouth disease (FMD) into the United
States. USDA's Animal and Plant Health
Inspection Service (APHIS) is working with the
U.S. military on Exercise Roving Sands, an annual
military exercise involving international
participants. Military personnel and
equipment from the United Kingdom, the
Netherlands, and Germany are headed to Texas,
Louisiana, and New Mexico to attend the U.S.
exercise June 15-24.

Because of active FMD outbreaks in the
United Kingdom and the European Union, USDA
is requiring that these three regions comply with
stringent agricultural safeguards to protect against
the introduction of FMD. USDA allows the
importation of military equipment from countries
affected by FMD, but only after they have been
thoroughly cleaned and inspected. USDA will not
accept any equipment that has been used in the
control or clean up of FMD outbreaks.

While Germany has not suffered from an
FMD outbreak, the country is subject to the same
strict entry requirements as countries currently
affected by the disease because it is part of the
European Union. U.S. military customs inspectors
and APHIS personnel have already precleared
Germany's equipment for the exercise, and the
equipment is currently enroute to the United States.

U.S. military customs inspectors and
APHIS personnel will be in the Netherlands and
the United Kingdom monitoring the cleaning and
inspection of all equipment from those regions
scheduled to participate in the Exercise Roving
Sands activities. The equipment will also be

Equipment from all three regions will be
reinspected upon arrival in the United States. Any

equipment that does not meet 'APHIS' cleanliness
standards will be refused entry and returned to the
ship. All personnel and their baggage will be
subject to inspection before their departure and
again upon arrival in the United States to protect
against the threat of FMD.

USDA takes every precaution, including
inspections, use of canine teams, and x-rays, to
ensure that military equipment from foreign
countries meets all required safeguards.

For more information about FMD, visit the
USDA website at www.usda.gov. For recorded
traveler information call 1-866-safguard.

APHIS Background
May 2001



We have conducted many trials on the
preconditioning calves with feed after weaning. In
three trials with Lykes Brothers Ranch in the
1970's, steer calves were fed 25 days after weaning
in covered, dirt pens at Wild Island. Pay weights
(liveweight less 3%) at weaning and out of the
preconditioning pens showed that calves gained 25
pounds. Each calf ate 205 pounds of a
preconditioning feed with free access to hay. Death
loss in Florida was 1%. Calves preconditioned
with feed in Florida subsequently gained faster and
had less sickness and deaths when finished in a
Texas feedlot than similar calves shipped direct
tothe feedlot at weaning.

In two trials in 1986 steer calves were fed
a commercial preconditioning feed 21 days after
weaning. In trial 1, calves shipped from Belle
Glade were fed in covered, concrete pens at Ona.
In trial 2, calves raised at Ona were fed in open,
dirt pens. In both trials, pay weight gains were 30
pounds per steer or 1.4 pounds per day. It required
273 pounds of preconditioning feed per calf.

In the 1990's Dr. Bill Brown conducted six
trials at Ona with heifer calves fed 30 days after
weaning in open, dirt pens. Feed treatments
included soybean hulls, soybean hulls + cottonseed
meal, and a commercial weaning feed. Pay weight
gain was 27 pounds per heifer with no difference
among the three types of feed. Preconditioning
required 275 pounds of feed per heifer.

In summary, calves preconditioned with
feed 4 weeks after weaning in Florida gain 30 to 40
pounds of pay weight. Adding feed, equipment,
vaccines, medications, facilities, and death losses,
it will cost $30 to $35 to precondition a calf four
weeks after weaning. With $100 per cwt for 500
pound calves and 1.25 pounds per day gain, one
would breakeven on a similar feeding program.

Will buyers pay a premium for calves
preconditioned with feed after weaning to provide

6 June 2001

a profit incentive? Dr. Michael King at Colorado
State University analyzed four years of sales data
accumulated by Superior Livestock Video
Auctions throughout the U.S. (King, et al., 1996,
1997, 1998, 1999, CSU Beef Program Reports).
The study involved a huge amount of data with
6,800 lots and 832,000 calves. Calves averaged
537 pounds when sold at a mean price of $67.21
and $74.16 per cwt for heifers and steers,

Dr. King compared sale prices of calves
receiving all vaccinations and sold at weaning with
that of calves similarly vaccinated but fed 45 days
after weaning (Vac-45). Calves fed 45 days after
weaning bought a $1.94 per cwt premium. With
current calf prices and a similar premium it is
marginally profitable to precondition calves with
feed four weeks after weaning in Florida. With a
lower price for feeder calves preconditioning with
feed becomes questionable.

Even if preconditioning is not profitable on
a pay weight plus a premium basis, it may be cost
effective to feed retained-ownership calves after
weaning because of production advantages
obtained later in the feedlot.

If calves are preconditioned with feed in
south Florida, be certain that they are fed in a high,
dry area. Heavy rains in July, August, and
September can result in standing water, muddy
conditions, low feed intake, poor gains, and
increase sickness and death losses.

An alternative is to contract feeding calves
with a commercial backgrounding operation 45 or
more days. A second alternative is to background
calves 45 or more days on good quality, well
drained pasture and a limited amount of dry
concentrate supplement, preferably during the early
fall months after the rainy season.

The important thing is to get calves on dry
concentrate feed and good quality forage (pasture
or hay) immediately after weaning whether shipped
or retained. Calves retained on the ranch, including
replacement heifers, should be fed dry concentrate

feed 3 to 4 weeks after weaning to maintain health.
When feeding is discontinued calves should have
access to good quality pasture.

'. 2001 PASTURE TO
Steer Performance
Evaluation in the Feedlot
& on the Rail

Florida's beef cattle industry with 975,000
cows ranks 12th in the U. S. and has the third largest
cow herd east of the Mississippi. The inventory
value of all cattle and calves in Florida on January
1, 2001, was $1,134,000,000 and produced cash
receipts of $309,852,000 in 1999. The Florida
beef industry must continue to be competitive and
we must improve the quality of our calves to
maintain our market share and value. Also
knowing the performance of your cattle on the rail
and in the feedyard is important when evaluating
new marketing alternatives that are being offered.

The first step in this process is to determine
what you are presently producing and where
improvement is needed. Pasture to Plate is a
program designed to give cattle producers valuable
information about their cattle that will enable them
to build on the strengths, as well as pinpointing
their weaknesses, in breeding, health and/or
management practices.

Pasture to Plate is an educational program
for cattle producers. The purpose is to give

7 June 2001

cattlemen the opportunity to: (1) evaluate the
feedlot performance of their cattle, (2) obtain
individual carcass quality and cutability
information on their cattle, (3) become familiar
with custom feeding practices and procedures, and
retained ownership without the investment and risk
involved in feeding an entire pen of cattle.

This program is sponsored by the
Marketing Committee of the Florida Cattlemen's
Association in cooperation with the Florida
Cooperative Extension Service.


1. Cattle will be custom fed at a commercial
feedyard after a 45 day commingled
backgrounding in Florida.
2. A consignor may enter a minimum of 5 head of
home raised steers averaging between 500 and 600
3. Consignments are due June 30, or Septermber
1, 2001 with a consignment fee of $100.00 per
head for trucking, feed cost and administrative
costs associated with collection and dissemination
of the performance and carcass data.
4. All cattle will be fed as a group. Each
consignor's cattle will be individually identified
with a numbered ear tag and a tattoo in the ear.
5. Each steer will be weighed and a market value
assigned by representatives of the Federal-State
Market News service to allow economic evaluation
of each steer in the lot and on the rail.
6. Cattle will be fed to an estimated low choice
carcass quality grade, or to a point of maximum
return potential, as determined by the feedlot
7. Steers remain the property of the consignor
and the CONSIGNOR assumes responsibility for
loss by death or injury.
8. The FCA Marketing Committee, its members,
members of the Florida Cooperative Extension
Service and the FCA staff are only a facilitator
who will arrange transportation, backgrounding
and coordinate the shipping, data handling and
dissemination of the data.
9. The feedyard will receive, process, feed and
market the cattle the same way they and the rest of

the industry routinely do. They will market the
cattle when they are finished and contract for the
collection of the carcass data at the packing plant.
They will individually weigh the cattle upon arrival
and again approximately halfway through the
feeding period. The cost of feed will be pro-rated
among the cattle and the feed bill (including
interest) plus the cost of carcass data collection
(approximately $6.00/head) and any medication
required will be deducted from the proceeds when
the cattle are marketed.
10. Only information pertaining to the entire pen,
or generic divisions thereof, will be made available
to the public and data from individual animals will
be kept confidential.


All steers must be:
Dehorned, castrated and healed.
Dewormed treated for lice and grubs.
Vaccinated twice for:
* Haemophilus Somnus
* Pasteurella (toxoid+cell antigen)
* 5 way Leptospirosis
* 7 way Clostridia blacklegg)

The second round of vaccinations must
be administered 15 days before the consignment
deadline with at least 21 days between the first
and second.

The steers must be weaned and taught to
eat from a bunk or tough and drink from a water
tank. The calves will be commingled and given
appropriate preventative health measures upon
arrival. Actual assembly dates are planned
approximately 15 to 30 days after the consignment
deadline. Shipment to the feedlot will be
approximately 45 days after assembly.


Don't send only your best or worst calves,
send a representative sample of your herd. If
trying to evaluate a bull for feedlot and carcass
traits you need to accumulate data on a minimum

8 June 2001

of 16 progeny. They do not all have to be fed in
the same year.
