Livestock Summary

Cattle inventories continue to
decline, restricting domestic beef
supplies. In spite of restrictions by
most countries on importing U. S. beef
due to the discovery of BSE, domestic
supplies cannot keep up with demand. Although
prices declined from the fall record, they strengthened
through early spring and the cookout season.
U.S. and Canadian beef face complete bans in
all major markets except the North American Free
Trade (NAFTA) countries of Canada, Mexico, and
the U.S. the NAFTA countries will allow beef imports
from Canada and the U.S. provided its boneless cuts
from animals less than 30 months of age. Canada
allows imports of U.S. cattle, but Mexico does not.
Strong stocker/feeder cattle prices are resulting
in larger imports from Mexico, but their cattle
inventory has also been declining, and availability
of animals for additional imports is limited. Exports
to Mexico resumed in March, but they have gradually
increased to only 50 percent of the pre-BSE levels
by early May.
While exports to Canada have been allowed
since January, they had only reached 6 percent of
year-earlier levels in March. The availability of
Canadian beef suggests it could be a formidable
competitor with U.S. in both the Mexican and
Canadian markets.

Weather conditions will be key to shift toward
broad expansion inbreeding inventories this summer
as restored grazing conditions and at least moderate
feed grain prices are still important variables. Drought
has been a persistent issue since 1998. Much of the
West and Northern Plains remains dry.

Supplies of irrigation water in many areas are
low, and harvest beyond the first hay cutting in all
areas will be important in determining herd expansion
over the next few years, regardless of cattle prices.
Grain prices have favored herd expansion since 1995-
96 when drought and record grain prices set off herd

Per capital beef consumption this year is
expected to rise nearly 2 percent from the low levels
of 2003 due largely to export bans on U.S. beef Total
red meat and poultry per capital consumption are
expected to decline in 2005 due to a decline in beef
and pork supplies and only marginal increases in
poultry production.

Cattle prices are expected to average neat record
levels in 2004 and 2005 due to strong demand from
end users. As prices and demand strengthen, more
cattle will be pulled forward to meet demand, but
the cost will be lighter slaughter weights and fewer
cattle grading Choice and higher.

USDA Veneman Authorizes
S Nationwide
Emergency Grazing
for Drought Relief

Agriculture Secretary Ann M. Veneman has
authorized emergency grazing on Conservation
Reserve Program (CRP) acres to provide relief for
farmers and ranchers in qualifying areas suffering
from this year's extreme drought.

"Emergency grazing on Conservation Reserve
Program acres will allow producers to provide
additional feed and forage for their livestock," said

Much of the western half of the country has been
impacted by severe drought conditions. According
to the U.S. Drought Monitor, a new area of
exceptional drought (the most severe form) was
introduced from southeastern Montana into western
Nebraska during mid-June. Until recently,
occasionally hot weather and short-term dryness in
those areas continued to aggravate the effects of a
multi-year drought.

The Secretary of Agriculture may authorize
emergency grazing of CRP acreage in response to a
drought or similar natural disaster. In addition,


managed haying and grazing of CRP acreage is
allowed under certain conditions.
This announcement authorizes emergency
grazing (including grazing during the nesting season)
of CRP acreage, in eligible counties only, until Sept.
30, 2004. To be eligible, a county must have suffered
at least a 40-percent deviation from normal
precipitation, or be at a D3 or D4 level for drought
as rated by the U.S. Drought Monitor. Under today's
announcement, Farm Service Agency (FSA) state
committees shall consult with the NRCS state
technical committees prior to approving counties for
emergency grazing during the primary nesting season
established for managed haying and grazing.
After a county has been approved, eligible CRP
participants may submit emergency grazing
applications at their local FSA office. CRP
participants who do not own or lease livestock may
rent or lease their grazing privileges. CRP annual
rental payments made to participants will be reduced
by a commensurate 10 percent for the areas grazed.
This reduction takes in to account the extreme
conditions that are prompting this action and is scaled
back from the 25 percent reduction requirement that
was in place in recent years. Haying or any other
harvesting other than grazing is not permitted at this
USDA has a Web site for producers to list
information concerning the need for hay or the
availability of hay for sale. The address for USDA's
Hay Net Web site is: http://www.fsa.usda.gov/haynet.
As indicated, haying is not currently authorized.
However, in qualifying counties, emergency haying
will be authorized after the end of the established
primary nesting season for the area with the same
payment reduction of 10 percent of the annual rental
CRP protects natural resources and improves
the environment. Under CRP, producers voluntarily
retire environmentally sensitive cropland for 10 to
15 years. Land to be enrolled must either be highly
erodible, contribute to a serious water quality
problem, provide important wildlife habitat or
provide substantial environmental benefits if devoted
to certain specific conservation uses. Currently, 34.6

million acres are enrolled in the program.
USDA offers additional programs to help
farmers and ranchers recover from drought and other
natural disasters, including the Emergency Loan
Program, Emergency Conservation Program, Federal
Crop Insurance and the Noninsured Crop Disaster
Assistance Program. More information on these
programs is available at local FSA offices and online
at: http://disaster.fsa.usda.gov.

USDA USDA to Award Up
STo $11.64 Million to
SStates and Tribes
for a National
Animal ID System

The U.S. Department of Agriculture's Animal
and Plant Health Inspection Service announced that
it is accepting funding applications from state and
tribal governments to support the initial
implementation of the national animal identification
system (NAIS). A total of $11.64 million will be
available for implementing an identification system
for all livestock and poultry animals on farms and
"A national animal identification program will
better equip the government and industry with the
means necessary to quickly control a variety of animal
disease outbreaks and reduce the economic impacts
on the market," said W. Ron DeHaven, APHIS
administrator. "This funding we're making available
to states and tribes will help move us toward
achieving this goal."
In April, more than $18 million was transferred
from USDA's Commodity Credit Corporation to
APHIS to begin implementing a national system that


will quickly and efficiently trace diseased or
potentially diseased animals to their point of origin.
Of this amount, more than $11 million is available
for state and tribal governments to focus chiefly on
premises identification. The remainder of the funds
will be used to support the development of the
national animal identification program, including
carrying out outreach activities and building database
In addition to registering premises, states and
tribes will have the option of carrying out field trials
or research for administering animal identification
and collecting animal movement data. APHIS will
distribute the funds through approximately 20
cooperative agreements. USDA aims to get the
components of the national premises system in place
first. Once the agreements are awarded, cooperating
states and tribes can use the funds to begin registering
Funding application packages are available on
the APHIS Web site at http://www.aphis.usda.gov/
mrpbs/fmd/agreements_announcements. html.
Applications can be submitted electronically to
neil.e.hammerschmidt@aphis.usda.gov or through
http://www.grants.gov. Paper applications also can
be mailed to USDA, APHIS, VS, c/o Neil
Hammerschmidt, NAIS coordinator, National Center
for Animal Health Programs, 4700 River Road, Unit
43, Suite 3A54, Riverdale, MD 20737.
The deadline for applications is 4:30 p.m. EST
on July 15. Following the selection process, all
applicants will be notified of their funding status.
APHIS anticipates awarding funds in August 2004.

Listening Sessions
on National Animal

The U. S. Department of Agriculture will hold a
series of listening sessions across the country to
discuss the development, structure and
implementation of a national animal identification
program for all livestock and poultry animals.
"These sessions will provide public forums to
discuss the national animal identification program,"
said Under Secretary for Marketing and Regulatory
Programs Bill Hawks. "A national animal
identification program will help the government and
industry more quickly control outbreaks of a variety
of animal diseases and reduce the economic impacts
on the market."

Agriculture Secretary Ann M. Veneman
announced in December 2003 that USDA would
expedite the implementation of a national animal
identification program. USDA's Animal and Plant
Health Inspection Service has received more than $18
million to begin implementing a national system that
will quickly and efficiently traceback diseased or
potentially diseased animals. Apremise identification
system will be completed this summer, which will
allow for the beginning of pilot programs to test
identification systems.
The first listening session will be held at Crown
Center (formerly known as the Charlie Rose Ag
Center), 1960 Coliseum Dr., Hospitality Suite A, in
Fayetteville, N.C. on June 14 from 1 p.m. to 3 p.m.
For directions, call the Crown Center at (910) 323-
Additional listening sessions will be held in:
Athens, Ga. on June 18; Prineville, Ore. on July 1;

E Research Shows One of
the Keys to Tender Beef

Some beef brands already promise consumers
a steak that is "guaranteed tender" every time. Now,
the results of a five year, checkoff-funded study may
help cattlemen identify the animals that can produce
that tenderness every time.
The Carcass Merit Project used DNA
technology to evaluate 11 regions on various
chromosomes in the cattle genome called
Quantitative Trait Loci. Their effect on heritable traits
such as tenderness, ribeye area, juiciness, marbling
and other qualities was measured across 14 breeds
and 8,500 progeny. With the data collected, the
individual breeds will be able to build expected
progeny differences (EPDs) scores for tenderness, a
quality consumers seek.
Funded by beef producers through their $1-per-
head checkoff, the project was coordinated for the
Cattlemen's Beef Board and state beef councils by
the National Cattlemen's Beef Association (NCBA).
The NCBA serves as one of the Beef Board's
contractors for checkoff-funded programs.
"By improving the average tenderness level of

beef available to consumers, the industry should see
an increase in the value of beef and an overall increase
in consumer expenditures," says Dave Nichols,
Carcass Merit Steering Committee member and a
seedstock producer from Bridgewater, Iowa.
"The National Beef Tenderness study back in
1999 found that except for the tenderloin, there was
a lot of variation for tenderness among beef cuts,"
says Elizabeth Dressier, director, Product
Enhancement Research for NCBA. "If consumers
switch to another meat because their last steak was
too tough, it costs the industry money. We did the
Carcass Merit Project to see if we could help
cattlemen develop genetic selection tools that would
aid in identifying cattle with quality traits that affect
the overall eating satisfaction of consumers."
The research showed that, to varying degrees,
all the breeds identified sires that can pass along
valuable beef quality traits to their progeny. It also
provided helpful information about chromosomal
regions within the bovine genome that influence these
quality traits. That information and the extensive
database will be a valuable tool for the further
identification of genes and the development of
commercially available gene tests for palatability
As part of the study, researchers at Colorado
State University were asked to assess the value of
tenderness. The greatest positive impact tenderness
exerts on retail price seems to be for cuts that would
grade USDA Choice or Select. For instance, a 1
percent improvement in tenderness could result in a
4.2 percent higher price for Select cuts.
Also, researchers believe that improving
tenderness will improve demand, with consumers
spending more for beef.
"While there are technologies that can address
tenderness in the post-mortem phase, they are a
perpetual cost," says Dressier. "Making genetic
improvements with sires that possess the desired
tenderness and quality attributes presents a permanent
fix to an old problem."
By developing a product mix that generally is
more tender, the beef industry could see more market


equilibrium and better revenue opportunities among
Choice and Select grading beef. Colorado State
researchers estimate that a 10 percent improvement
in tenderness would add about $150 to $170 million
to the industry.
The data from the study would suggest there is
room for improvement. The Warner Bratzler Shear
Force test measures tenderness by how much force
is needed to cut a 34-inch core of steak. In this study,
it was determined that consumers consider steak that
requires 11 pounds or more of force as "slightly tough
or tougher."
The results found 26.2 percent of the cattle had
Warner Bratzler scores of 11 pounds or greater. A
sensory panel scored 19.4 percent as slightly tough
or tougher. This is in line with previous studies that
determined that as many as one in four steaks may
be considered too tough to chew.
The results of the Carcass Merit proj ect will play
an important role in the future of genetic technology
and selection for the cattle industry. Cattle breeders
can immediately utilize the results of this study by
computing EPDs for shear force and sensory traits.
As for the future; the information and data collected
for this project will aid the industry as it rapidly
moves in the direction of selecting animals for end
product quality.

Pigs' Mosquito Bites
Hurt Pork Producers

High numbers of mosquitoes
will lead to increased bites on pigs this summer,
costing pork producers money due to greater trim

losses at packing plants, a University of Nebraska
swine specialist said.
"The increased carcass trim will cost producers
anywhere from $5 to $10 per pig," Mike Brumm, an
Institute of Agriculture and Natural Resources swine
specialist, said in a news story published by the
institute. "If you raise pigs in curtain sided barns,
you've seen pigs with more red welts. This is a huge
problem in the industry right now."
Agriculture Department inspectors have asked
plant workers to trim areas with the welts, Brumm
said in the report.
Brumm recommends reducing mosquito-
breeding sites by keeping areas around hog barns
clean, mowed and free of standing water. Livestock
waste lagoons, however, have too much organic
matter and wave action for mosquito breeding.
Mosquito-control insecticides are available as well.
Disease is not a concern, as pigs are not carriers
of West Nile virus, Brumm said. "The main problem
is the bites themselves."

New USDA Lab to
Study Stress
Indicators in

The Agricultural Research Service has opened
a new 2,300-square-foot Farm Animal Behavior and
Well-Being Laboratory today in West Lafayette, Ind.,
for the study of stress indicators in livestock.
Researchers at the new laboratory also study the
relationship between stress and the ability of
pathogenic bacteria to establish themselves in
animals. ARS is the chief scientific research agency
of the U.S. Department of Agriculture.





The new facility adjoins a 10,000-square-foot
laboratory built in 1997 to house ARS' Livestock
Behavior Research Unit, which conducts behavioral
studies of swine, cattle and poultry.
Purdue University animal scientists work
alongside ARS scientists on the Purdue campus and
at the Purdue Animal Science Farm about 15 miles
north of the main campus. Purdue hosted a dedication
ceremony today for its Swine Environmental
Research Building, located on the university farm
near the new ARS laboratory.
ARS Acting Administrator Edward B. Knipling
said the new ARS lab will complement the behavioral
studies under way in the animal lab to find possible
objective measures of animal stress.
"Stress in livestock can lower productivity and
possibly increase the risk of contamination from
Salmonella and other bacterial pathogens," Knipling
Donald C. Lay, research leader and animal
behavioralist at the lab, is working on an imaging
system to show the movement of Salmonella bacteria
through live pigs. He and colleagues are also
researching alternative housing for poultry and
In tandem with the housing research, the ARS-
Purdue team is pioneering the idea of breeding
nonaggressive animals to reduce losses and stress.
This includes selecting sows whose maternal
behavior makes them less likely to injure their piglets,
a problem that costs farmers more than $600 million

S\Senator Says
SVoluntary COOL
SBill Unlikely to
Pass This Year

The status quo on country of origin labeling is
likely to remain through 2004 because of election
issues, Sen. Chuck Hagel, R-Neb., said, according
to the Grand Island (Neb.) Independent.
A recent bill designed to make COOL voluntary
will likely be unsuccessful, especially if the
legislation makes it to the Senate, Hagel said. (See
House Ag Committee introduces voluntary COOL
bill, Meatingplace.com, June 16, 2004) but attempts
to reverse the Sept. 30, 2006, extension of mandatory
COOL will also fail, he said.
"I really don't think you are really going to get
any action this year in the Senate," Hagel said. "There
is going to be very little action on anything here in
the Congress, specifically the Senate, because of
Mandatory COOL was introduced in the 2002
farm bill and slated to go into effect this October.
But a provision in a later appropriations bill pushed
the implementation back until 2006, except for fish
and seafood.
