As of September 13, 2001, a total of 82 horses
have tested positive for WNV with an estimated 25-
30% being fatal. In endemic areas, people who have
suspect horses are reluctant to report them due to the
cost of testing. Horse owners in areas where the virus
has not yet been reported, are encouraged to participate
in the surveillance efforts and report the cases. As of
now, the furthest South that an equine case has been
reported, is Marion County (one Citra horse reported
last week), and so far, a total of three cases have been
reported in Alachua County.

A vaccine is now available through your
veterinarian. It has been tested for safety requirements
in trials involving approximately 650 horses, of which
half a dozen experienced minor side effects (i.e. sore
spot at injection site, mild colic, etc.). Due to the need
for early release of the vaccine in the face of the
outbreak, efficacy trials results are pending. Therefore,
the vaccine has been released under a conditional
license meaning it needs to be administered by a vet.
We expect reasonable efficacy due to the company's
record in producing similar vaccines. In the meantime,
the major risk taken by owners when they vaccinate is
lack of efficacy information. That is, we don't know
for sure if it will provide the horses any protection. It is
not labeled for use in pregnant mares because
insufficient numbers of such animals were used in
safety trials. However, five pregnant mares were
vaccinated in the trials with no side effects. Due to the
nature of the vaccine (killed virus), no side effects are
expected in mares or fetuses. In addition, weanlings
may be vaccinated. No competition with passively
acquired immunity is expected because mares were not
exposed to the virus last year (unless they were living
in New York!). Therefore the vaccine should be as
effective in foals as in adult horses. Keep in mind that
all horses will need a booster the first year of
vaccination. Large numbers of horses were probably
exposed to the virus in areas such as Jefferson County
and are likely to have mounted their immune response
by now. Ultimately, it is up to the owner to make a
decision to vaccinate or not. To learn more about the
vaccine, please visit these web sites:

Sprouts, those crunchy little greens that liven up
salads, can make you sick. And the odds are a lot
higher than they are for supposedly dangerous,
pathogen-laden red meat.

Not that the meat industry wants to spread any
bad news, but a new study reported by ABC News
and published in last week's Annals of Internal
Medicine found that more than one-half of confirmed
food-borne illnesses in California were linked to
alfalfa or clover sprouts in 1996 and 1998.

The study investigated six multi-county
outbreaks of bacterial infection in California from
1996 through 1998. There were 600 confirmed cases
of disease, and two deaths associated with eating
sprouts. The study estimates that an additional 22,800
people were infected, but never realized that sprouts
were the cause.

The study's lead author, Janet Mohle-Boetani of
the Los Angeles County Department of Health
Services, reported that during the study period,
sprouts caused more outbreaks than any other food;
though the common perception is that undercooked
meat, and eggs and contaminated water supplies are
usually the at the top of the offender list when it
comes to E. coli 0157:H7 and salmonella.

The seeds from which sprouts are grown are
often the source of the bacteria. The seeds can be
contaminated by irrigation water, fertilizer containing
animal manure, or by grazing livestock.

To grow sprouts, the seeds are put into a rotating
drum and misted with warm water. They are left at
room temperature to sprout, providing a perfect
incubator to increase the population of bacteria that
may be present. The sprouts are most often eaten raw
on salads and sandwiches, leaving the bacteria

The Food and Drug Administration suggests
cooking the sprouts in order to kill any bacteria that
might be present. "In order to minimize risk for food-

borne illness avoid raw sprouts," said a spokesperson
for the FDA.

Washing sprouts is not effective, because
bacteria on the seed can become internalized during

The FDA recently released a consumer advisory
for sprouts. Guidelines were also put in place for
decontamination of seeds. All growers are required to
sanitize the seeds chemically before growing sprouts.
The FDA has also approved irradiation for
decontaminating seeds, but not for sprouts.

The MEATing Place
Release August 30, 2001


Six years ago in 1995 a group of UF/IFAS
extension faculty and Florida cattlemen toured the
feedlot industry in Oklahoma and Texas. At that time
most fat cattle were sold on a cash or weight basis at
the feedlot. Little emphasis was placed on value-
based marketing or carcass merit.

This past March (2001), Payne Midgette and I
toured several feedyards in the Texas panhandle, and
oh what a change. It is estimated that 60% of fat
cattle are now being sold on a grid. A grid is a
formula that pays for carcass merit. Premiums are
paid for high quality grades (choice and prime), high
yielding carcasses (yield grades 1 and 2), large rib
eyes (> 12.5 square inches), and a low back fat
thickness (< 0.5 inches). Grids discount low quality
grades (especially standard), low yielding carcasses
(yield grades 4 and 5), small loin eyes (< 12.5 square
inches), and a high back fat thickness (> 0.5 inches).

October 2001 5

There are several grids, each placing emphasis
on specific quality traits. Most grids heavily discount
dark cutters, and heavy (> 949 lb) and light (< 600 lb)
carcasses. Some grids even discount brands,
implants, and kidney fat.

One Texas rancher-feeder shared a print-out or
spread sheet on a pen of heifers finished at McLean,
Texas and sold on a grid. We were amazed at the
amount of information that the packer provided on
each carcass to establish market value. The spread
sheet gave rib eye area, carcass grade, back fat
thickness, carcass weight, dressing percent, and %
kidney fat. These data can be used back at his ranch
to cull cows, select heifers, and improve his bull
buying plans.

Most interesting about the above carcass data
was the $300 difference in the price paid for the
lowest and highest value carcass. A good proportion
of this value difference was due to carcass weight;
but grade, yield, and muscling (rib eye area) had high
dollar effects.

With the technology to identify calves at birth or
weaning and follow them with scanners and
computers all the way to the rail and meat counter,
value-based marketing is here. More and more
Florida calves will be purchased on their ability to
gain well and efficiently in the feedlot, and produce a
good-quality, high-yielding carcass.

Even for cattlemen that sell small lots of calves
through public auction markets, the technology is
available to identify their calves and follow them to
the rail. This will allow any cattlemen to develop a
sound breeding and production program that will be
recognized by the feedlot and packing industry.
Cattlemen that make an effort to develop good
reputation calves will be rewarded with premiums,
and those that do not will have their calves
discounted accordingly.

6 October 2001


FORT PIERCE, Fla.---Until 1948, it seemed that
Florida cattle production would be forever limited by
the state's withering heat and humidity.

Then came Alto "Bud" Adams, Jr.

Adams understood the problem firsthand.
Growing up on his father's ranch near Fort Pierce
he'd raised the small, hardy Spanish cattle Florida
was known for -- they tolerated the climate but didn't
perform well in the marketplace. Retailers and
consumers favored improved beef breeds like the big
Herefords that thrived in the Midwest.

In 1948, Bud Adams decided to develop superior
beef cattle suited to Florida conditions by
crossbreeding Hereford bulls with Brahman cows, a
breed developed from Indian cattle to withstand hot,
muggy weather.

"Those Hereford bulls came from Kansas, and
they didn't last long in this heat," Adams said. "I
wanted to try using the crossbred bulls as breeding
stock, which was something cattlemen weren't
supposed to do back then."

In the early 1950s, Adams sought advice from
Marvin Koger, a cattle geneticist with the University
of Florida's Institute of Food and Agricultural

"Dr. Koger said it would take about four
generations of crossbred to crossbred matings to
achieve uniformity," Adams said. "By the fourth
generation they were breeding 99 percent true to
type, and I knew we were onto something."

Bud Adams called his cattle Brafords and
standardized them at 3/8 Brahman and 5/8 Hereford,
he said. Heat-tolerant yet growth, the animal
became a favorite of Southern ranchers and one of
the few recognized beef breeds developed in the 20th

Fifty years after he began developing the
Braford, Bud Adams has become a symbol of Florida
agriculture and its ability to cope with change. While
adopting the latest scientific innovations, he remains
a staunch conservationist. Known as one of the state's
premiere cattlemen, he has diversified into citrus
production and ecotourism.

And despite half a century of accomplishment,
Bud Adams remains focused on the future.

"Bud has foresight. If there's a better way to do
something, he'll try it," said Findlay Pate, director of
UF's Range Cattle Research and Education Center in
Ona. "You can't stand still in the cattle business."

Alto "Bud" Adams, Jr., a leading Florida cattleman,
relaxes on the front porch of a replica "cracker" house at
his ranch in Fort Pierce. The house is seen by thousands
of visitors each year during "eco-tours" of the 18,000 acre
ranch. Best known as developer of the Braford beef cattle
breed, Adams has worked with University of Florida's
Institute of Food and Agricultural Sciences for 50 years to
develop and popularize innovative cattle production
methods. (Photo by Milt Putnam, University of

October 2001 7

Over the years, Adams has tried, and
popularized, many production methods developed by
UF scientists. Pate considers him a valuable ally to
the Ona center.

"When Bud Adams talks, Florida cattlemen
listen," he said. "Several years ago we found that you
don't need phosphorus amendments to grow bahia
grass, the state's most popular cattle forage. This was
a break with tradition, but Bud followed our
recommendations and other ranchers followed Bud.
Everyone saved money and helped protect water

In the early 1980s, Adams donated 250 head of
Braford cattle to the Ona center for research
purposes, Pate said. After several generations of
breeding, the Brafords now comprise about half of
the center's 1,019 cattle.

"Those Brafords have been vital to our research,"
he said. "Through his generosity, Bud has helped
IFAS improve the entire Florida cattle industry."

Jim Handley, executive vice-president with the
Florida Cattlemen's Association, said Adams'
attention to the "big picture" is well known to the
state's ranchers. Adams was president of the
association in 1958 and has remained active ever

"Cattlemen need to maintain a positive
relationship with the community at large, and Bud
emphasizes that," Handley said. "He's an outstanding
spokesperson for our industry because he enjoys
educating the public, and he's very conscious of the
rancher's role in protecting the environment.

"Bud will tell you that it all starts with the land,"
he said. "South Florida's cattle industry is successful
because the land here supports great forage grass, so
it's our responsibility to keep nature's balance."

Handley said Adams always looks to nature for
solutions to ranching management problems. Rather
than rely on chemical pesticides to kill insects,
Adams promotes biological pest control using native
predators. To keep pastures healthy, he allows them
to "rest" after cattle have grazed for several weeks.

"Sustainability is becoming more and more
important for ranchers," he said. "Bud has been using
it as the foundation of his business for decades."

There are actually three Adams Ranch operations
in Florida, located in Osceola, Okeechobee and St.
Lucie counties, said Mike Adams, Bud's second-
eldest son. Mike is a third-generation University of
Florida graduate and president of Adams Ranch, Inc.
Lee, the eldest Adams son, manages the Osceola
County ranch. Rob, the youngest, manages the
Adams Ranch Citrus Company, known as ARCCO,
based at the St. Lucie County ranch.

Best known of the three, the St. Lucie County
ranch is where Bud grew up. His father, Alto Adams,
Sr., an attorney and Florida Supreme Court justice,
purchased the ranch in 1937 after his doctor advised
him to spend more time outdoors, Mike Adams said.

Located near Fort Pierce, the 18,000-acre ranch
is headquarters for the family business, where new
ideas are first put into practice. Like the other Adams
operations, the Fort Pierce ranch produces Braford
cattle and sells them as breeding stock, but it also
grows 2,000 acres of citrus and is home to a thriving
ecotourism business.

"When we got into ecotourism it raised a few
eyebrows," Mike Adams said. "After all, this is a
working cattle ranch. But Dad knew it was a good
way to establish a deeper connection with the

Since 1996, the Fort Pierce ranch has hosted
tours from January through June, attracting about
9,000 visitors per year, he said. Traveling in open-air
buses over dirt roads, they get a glimpse of the real
South Florida.

The property looks much the same today as it did
centuries ago, a blend of cabbage-palm hammocks
and open grassland, Mike Adams said. Besides the
dirt roads, fences and spring fed canals, there are few
signs of man's involvement.

Except, of course, for the cattle. Brick-red bulls,
cows and shy calves are everywhere, sometimes
temporarily blocking the roads, always staring
curiously at human passers-by. A surprising number
of cattle lounge in the noonday sun.

8 October 2001

"Brafords are comfortable in the sun," Mike
Adams said. "The short, light-colored hair increases
their heat tolerance."

Cattle are hardly the only creatures present. Deer
and wild turkey feed warily in the pastures, while
red-shouldered hawks and sandhill cranes make
appearances overhead. In the canals, wading birds,
fish and turtles mingle, along with the occasional

Near the garage where the tour buses are stored
is an ordinary-looking pasture that holds the next step
in Adams cattle production. Known as ABEEF, they
are a composite of Hereford, Brahman, Red Angus
and Gelbvieh cattle, developed for faster growth and
better muscling and marbling.

"In 1990, we started asking ourselves what
improvements we could make for the 21st century,
and this is the result," Mike Adams said. "We sold
our first ABEEF bulls last year."

Tim Olson, a UF animal sciences associate
professor, said that so far, the ABEEF cattle are
fulfilling their promise. In the early stages of the
ABEEF project, Bud Adams invited Olson and other
UF beef production experts to a conference where he
explained his goals and asked for input.

"They knew exactly what they wanted to
accomplish to meet the needs of the marketplace,"
Olson said. "And they had done their homework. Bud
has been in this business long enough that he can
anticipate the consequences of research developments
and market trends."

If Bud Adams doesn't have a crystal ball to see
the future of Florida beef production, UF animal
sciences professor Roger West has provided him with
the next best thing. Using medical ultrasound
equipment, West can evaluate the carcass
characteristics of live cattle.

By directing ultra high frequency sound waves
into the animal's body and electronically monitoring
them, a sound "picture" is formed, he said. The
results are then converted to visual data and
interpreted by a technician, who can predict the size
and quality of various cuts of beef the animal will
yield. This information can help breeders maximize
desirable traits.

"This sounds like science fiction to some
people," West said. "But when Bud heard about the
method he immediately recognized its potential.
Today, every Adams Ranch bull gets ultrasound
analysis and we'll probably start using it on the
heifers soon.

"Bud is always looking a little further down the
road," he said. "That's what keeps him on top."
