The total meat production in
2002 is projected by the USDA to
be about 84 billion pounds
nationally, up one percent from a
year ago. Beef production is
expected to remain nearly
unchanged from last year, but
pork production are expected to be up
Drought conditions are forcing more cattle into
feedlots. The weather is possibly delaying herd
expansion for at least another year.
Conditions coming out of the winter, without
improved soil moisture conditions or snow pack to fill
reservoirs, have raised even greater concerns for spring
and summer forage and grazing prospects.
Projected meat exports in 2002 are expected to fall
about two percent from last year. All major meats are
expected to register declines. A stronger U.S. Dollar is
also contributing to the decline in export potential.
Greater meat production, however minor, and
lower exports are pressuring domestic prices downward.
Although fed steer prices are expected to register a year-
over-year price gain, the projected increase is below
earlier expectations as larger than expect placements
boost beef production.
July 2002 3
Beef cow slaughter, while below the large levels of
a year earlier, are above 2000 slaughter levels. Dairy
cow slaughter is historically low and consequently total
cow slaughter continues to decline.
Beef production estimates have been increased for
the year because of the larger numbers of cattle forced
into feedlots and continued record slaughter weights.
Beef production in the second and third quarters is
now expected to exceed year-earlier levels. Fourth-
quarter production is expected to average below a year
earlier. Continued poor grazing prospects and even
larger feed lot placement could push production up.
Dressed weights remain sharply above the weather;
reduced weights of the first half of 2001 are declining.
Fed cattle prices have remained relatively firm this
year, however well below the weather induced levels of
a year earlier. Increasing slaughter weights and numbers
in later April and May have pressured prices downward.
Cattle prices in 2003 are currently projected to
increase from the anticipated 2002 levels. Smaller
inventories and stronger demand will drive prices. Cow-
calf operators can expect to profit from the price run up.
The weather is already causing concerns about the
summer of 2002. Pasture conditions in the panhandle
have been adequate, but with the shortage of rain, higher
than normal temperatures in May are raising doubts
about the forthcoming summer.
The lack of rain is causing critical conditions for

2002 Pasture To
Florida's beef cattle industry, with 958,000 cows,
ranks 12th in the U.S. and has the third largest cowherd
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 producer's 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

Pasture to Plate is an educational program for
cattle producers. The purpose is to give 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.
The Marketing committee of the Florida
Cattlemen's Association in cooperation with the Florida
Cooperative Extension Service sponsors this program.

Pasture To Plate Program
For 2001-2002 Completed
It seems like it has taken a long time to get the
Pasture to Plate cattle finished aid harvested this year.
The cattle were assembled in October and harvested in
late May. Given the volatility and depression in the fed
cattle market all spring, I kept hoping it would rebound
by the time our cattle were ready. It didn't, but the good
news is we marketed the cattle before the market
bottomed, if it has. The cattle were marketed to Excel on
a grid with a Choice,Yield Grade 3 base at $110.00/cwt.
of carcass. This equated to $72.10/cwt. (based on their
dressing % or yield) live when the cash market was
$67.00 or $64.00 depending on which week you price
them. When Excel got through with the discounts and
premium adjustments we were paid $107.17/cwt.
dressed or $70.21/cwt. live. The cattle did well, better
than any previous Pasture to Plate group, 69% Choice,
27% Select and 4% no roll or Standard quality grades
and yield grades were 46% YG 2 and 46% YG3,
4%YG1 and 4% no grade. The overall performance of
the group was depressed by one carcass that was no roll
(Standard) and light weight (less than 550 lbs.).
The cattle's health in the feed yard was excellent
since they did not treat a single animal, though the poor
performance of the one animal suggests that at some
point in its life it must have been sick and just didn't
show it. They averaged a daily gain of 2.81 lbs which is
below the industry minimum target of 3.0. One of the
consequences of a slower rate of gain is generally poor
feed conversion and in this case this is true. The cattle
converted 8.4 lbs. of feed as fed to a pound of gain or on
a dry matter basis 6.7 lbs. of feed per pound of gain. The
industry target is to be below 6, preferably below 5.5.
This impacts the cost of gain and in this case the cost of
gain (total pounds gained/total feed yard charges) is
$0.54 according to my figures. The feedlot manager told
me they closed out 7 lots at that time and 4 were less
than 50 and 3 were over.
In summary, the cattle did very well in the packing
house and only fair in the feed yard. Financially they lost
$30.27 per head when all costs are considered compared
to their value at the start. While this is not good, we were
successful in getting good individual animal data in the
feed yard and in the packing plant, and they were not the
100 to 200 dollars per head losses we have been reading
about. If you have any questions, don't hesitate to call.

UF Researchers Develop
Biocontrol For Destructive
It sounds like the name of an exotic new drink, but
tropical soda apple has been more aptly described as the
"plant from hell," say University of Florida researchers
who have developed a natural way to control the rapidly
"The highly invasive plant, which forms a dense
and thorny thicket that is impenetrable to animals and
people, has been classified by the federal government as
one of the nation's most noxious weeds," said Raghavan
Charudattan, professor of plant pathology with UF's
Institute of Food and Agricultural Sciences. "In Florida
and seven southeastern states, it's literally taking over,
displacing native plant species in infested areas."
He said the weed, native to South America, is a
serious environmental threat to natural areas, and it's
become a major problem for the beef and dairy cattle
Sharp thorns make the plant's foliage unpalatable,
but livestock, wild animals and birds that eat the fruit
help spread the seeds. Mature plants can produce 50,000
seeds that germinate under a wide range of conditions.
Seeds also can be spread by compost, sod and moving
water, Charudattan said.
Another concern, he said, is that cattle shipped out
of Florida may harbor plant seeds in their digestive tracts
and spread the weed to neighboring states. To stop the
spread of seeds, Georgia, South Carolina and other
southeastern states may require Florida cattle to be held
on weed-free pastures for 10 days before being shipped
to nearby states.
"Pastures infested with the weed have less area
available for cattle grazing, which means the stocking
rates the number of animals per acre must be
reduced," Charudattan said.
Wade Grigsby, vice president of the cattle division
for Alico Inc. in LaBelle, said the weed is an economic
and environmental headache for the livestock industry.
"It may be impossible to eradicate tropical soda
apple, but Charudattan's new biocontrol is the best
option we have for bringing the weed under control,"
July 2002 5
Until now, the only way to control the weed was
with repeated mowing and chemical herbicides. But,
Charudattan said, applying herbicides is a problem for
the cattle industry because of possible chemical residues
in milk and meat.
Charudattan's research has shown that a common
plant virus can be used to kill tropical soda apple, and he
is seeking commercial partners to produce and market
the virus as a natural biocontrol or bioherbicide.
"During a routine examination of several plant
pathogens for their ability to cause disease on tropical
soda apple, we discovered that tobacco mild green
mosaic virus (TMGMV) kills the weed," he said. "Tests
in two pastures demonstrated the virus kills up to 97
percent of the weed."
To determine which plants may be vulnerable to
the virus, Charudattan is testing the virus on some 200
different plant species, including other weeds and
cultivated plants. The virus does not affect people or
animals, he said.
"We know that some varieties of tobacco and
peppers are susceptible, but the virus can be used safely
in areas where tobacco and peppers are not grown," he
The virus, which can be applied easily and
inexpensively with a portable back-pack sprayer, is
effective against tropical soda apple under a wide range
of temperatures and year-round growing conditions.
Charudattan said the bioherbicide would be easy to
produce. "High concentrations of the innoculum can be
produced inexpensively in tobacco plants and stockpiled
for use. It remains effective for decades," he said.
Susceptible tobacco plants could be used to mass-
produce a commercial bioherbicide. As they mature,
infected leaves are harvested, freeze-dried and ground
into a fine powder for storage at room temperature, he
"To demonstrate how easily the bioherbicide could
be produced, we are establishing a pilot production
facility at UF," Charudattan said. "The prototype
production system could be established as a self-
sustaining service from UF or licensed to a commercial

4, 2002. Charudattan, a plant pathologist, has developed a natural way
to control the rapidly spreading weed without pesticides or mowing. He
said a common plant virus, which is not harmful to people or animals,
killed the weed in the container. Tropical soda apple forms a dense
and thorny thicket that is impenetrable to animals and people, and it
has been classified by the federal government as one of the nation's
most noxious weeds. (AP photo: University of Florida/IFAS/Thomas

Both EEE and WNV are mosquito-bome illnesses,
said Florida Agriculture Commissioner Charles H.
Bronson, who explained that the cases being detected
now are happening before the onset of Florida's
traditionally rainy season when mosquito populations
increase, and that could suggest that the state is in for a
tough year in terms of mosquito-bome illnesses.
Visitors to Florida, as well as residents, are
encouraged to take precautions against mosquitoes,
Bronson said, including avoiding outdoor activities after
dark, wearing long sleeves and long pants when it is
necessary to be outside during non-daylight hours, and
wearing insect repellent while outside. Certain types of
mosquitoes are active biters during the day, so
precautions against mosquitoes should be taken at all
times. Bronson also suggested removing standing water

the U.S. Department of Agriculture is releasing
$2,231,451 to the state of Florida to bolster food and
agricultural homeland security protections, out of a total
of more than $43 million being provided to states. The
resources are part of $328 million approved by President
Bush and the Congress earlier this year to strengthen
USDA's homeland security preparedness.
"These grants are an important component of the
Administration's continued efforts to strengthen
homeland security protections for America's food and
agriculture," said Hawks. "States, local communities,
academia and the private sector are all critical partners in
making sure we are prepared in the event of an

Under Secretary Hawks was joined by Florida
Agriculture Commissioner Charles Bronson in
announcing the state's homeland security funding. This
week, Agriculture Secretary Ann M. Veneman and
Under Secretary Hawks, along with several USDA
subcabinet members, are traveling to nearly a dozen
states to discuss the importance of homeland security
with Congressional, State and local officials and actions
that federal, state, private sector and academia are taking
to improve agriculture protection systems.
The state of Florida will receive $2,231,451 in
funding. Of that, $1,650,000 will be used for rapid
detection and diagnostics network, $350,000 will be for
plant pest and disease detection, $162,045 will be for
animal disease response, and $69,407 will be for animal
Earlier this year, USDA also announced additional
homeland security allocations which include:
S$177 million to make physical and operational
security improvements at key USDA locations. This
provides $64 million at the animal disease center in
Ames, Iowa to relocate labs from leased space into the
main Ames campus and includes funds for a new facility
for sensitive diagnostic work, which will be completed
in 18 months.
$23 million for USDA's Plum Island laboratory,
pending an independent review of the critical needs and
options for the facility.
$35 million to strengthen the Agricultural
Quarantine Inspection program to exclude agricultural
pests and diseases at the borders. These funds are being
used to expedite development of an automated system of
inspections in coordination with the U.S. Customs
Service. In addition, USDA is purchasing 100 rapid
pathogen identification devices and hiring additional
$16.5 million for the Food Safety and Inspection
Service to increase monitoring, provide training to
inspectors and expand technical capabilities. $1.5
million of these funds are being used to hire additional
inspectors for imported meat and poultry.
$15.3 million for the Agricultural Research
Service to improve rapid detection technologies for foot
and mouth diseases as well as other animal diseases.
