Livestock Summary

The current cattle market is
S presenting some interesting
opportunities for Florida's cow calf
Operators. A rainy year, too rainy
by some accounts, has also offered
some challenges.
Frequently one sector of the cattle industry is
profitable at the expense of another sector. The
Canadian beef situation and the current herd reduction
have created a new profitability dynamic.
So how much higher can beef go? The price ratio
of beef prices as compared to pork and chicken prices

has continued its acceleration of the past few years.
Existing trends suggest that this will continue for a while

The North American beef industry has become
increasingly concentrated over the last ten years. The
two largest beef packers in Canada are two of the
largest packers in the U. S.

Recent years have seen both box beef and cattle
imported from Canada. Likewise, both have been
exported to Canada in smaller quantities.

Cyclical herd liquidation has been underway in the
U.S., Mexico, and Canada. Weather induced cow
slaughter has been large again this year. Dry conditions
and reduced forage has delayed herd expansion for at
least another year.

About eight to 10 percent of U.S. beef imports
are either Canadian cattle or box beef. Removing that
import volume from the marketplace and the current
tight supply for high-quality beef tighten the situation

The earliest that beef production can increase is
2006, and that is only if more heifers are retained and
bred in 2004. Ahard winter will negatively impact the
selling trend and push herd expansion further out.

Beef supplies will decline even more in 2004 and
2005. At the same time, beef supplies will become
temporarily shorter as the herd expansion signals
become stronger and more females are retained.

Florida's cow-calf operators are carefully
observing. Demand and prices for quality feeder cattle
will be strong if the planned herd expansion proceeds.
Weather will play a maj or roll in any trend that develops,
to nobody's surprise.

Other factors that have potential influence on
livestock demand are the economy and eating trends.
A slip or slowing of the general economic recovery will
negatively shift the price of beef, but the prospect for
this happening is marginal.

Another potentially influential factor is eating trends.
Much is currently being said about the collective
waistline of America. To date, beef is still in a favorable
light with most consumers.

* Stocker cattle management
* and nearly 100 more


Cattle Today

National Animal Identification

Since September 11, 2001, our nation has been
on a heightened state of alert. Threats to our livelihood
and way of life not only include direct assaults, which
result in loss of lives, but also assaults on our food supply.
Several foreign animal diseases pose a threat to
production agriculture in the United States. With this in
mind, it has been proposed that the United States needs
a traceback system in place that can identify all animals
and premises potentially exposed to foreign animal
disease within 48 hours after discovery. The only way
to accomplish this goal is with a National Animal
Identification Plan that is mandatory for all producers.
In October of 2003 the National Animal ID
Program was released to the public. The plan was
requested by the United States Animal Health
Association and has been in development phases for a
couple of years. Animal and Plant Health Inspection
Service (APHIS-a branch of the USDA) and over 100
animal industry professionals (representing more than
70 national livestock industry organizations) were
involved in the development of the plan.
Many beef producers may see this as yet another
regulatory hurdle that must be dealt with. Cattle fever
tick and Brucellosis eradication programs were very

much viewed in this light when they began. The US ID
plan encompasses all species including: bison, beef
cattle, dairy cattle, swine, sheep, goats, alpacas, llamas,
horses, domestic deer and elk, poultry (eight species
including game birds) and aquaculture (eleven species).

Implementation of the National Animal ID program
will occur in phases. Phase one will involve a premise
identification system that must be in place by July 2004.
Management of the premise ID is the responsibility of
each state department of agriculture. The premise ID is
needed at all locations in the livestock production chain
including markets, assembly points (order buyers),
exhibitions, processing plants, etc., so that an animal
can be tracked through every location where it may
have come into contact with other animals.

Phase two stipulates all cattle, swine and small
ruminants must possess individual or group lot
identification for interstate movement by July 2005 with
the remaining species in compliance by July 2006.
Individual ID is necessary for tracking animals that are
destined to be commingled with other animals as they
move through the system. Acceptable means of
identification include Visual tags (with a country code
and individual number), however, the accepted means
of ID forbeef producers will most likely be an electronic
ID ear tag. The electronic ear tag will facilitate transfer
of information, remove human error, and allow 48-hour
traceback. Groups of animals that are never commingled
(for example, a load of cull cows that are sold directly
from the ranch to the packer) can be assigned a group
ID and do not need to be individually identified.

Phase three involves enhancing the ability to track
animals through all marketing channels. These date
deadlines were established only as guidelines for imple-
There are still many unanswered questions about
the National ID plan. For instance:
* What is the definition of a premise?
* What if a producer runs cattle in two separate
counties? Does he have two premise ID's?
* What if the producer runs cattle in two separate
states? Does he have to work with the Animal
Health Commission in each state?
* What forms of ID are acceptable?


* Who pays for the electronic tag placed in the left
* What is the producers liability?
* Who polices the program?
Lots of questions remain to be answered but one
thing is for sure, the National Animal ID plan is starting
to take shape and will happen within the next five years
in some form. Additional information and the complete
74-page summary of the National Animal ID Plan is
available at www.usaip. info.

USDA Issues Proposed Rule for
Mandatory Country of Origin

The U.S. Department of Agriculture today issued
the proposed rule for the mandatory country of origin
labeling program as required by the 2002 Farm Bill.

Under the proposed rule, muscle cuts of beef
(including veal), lamb and pork; ground beef, ground
lamb and ground pork; farm-raised fish and shellfish;
wild fish and shellfish; perishable agricultural
commodities (fresh and frozen fruit and vegetables);
and peanuts must be labeled at retail to indicate their
country of origin. In addition, the notice of country of
origin for fish and shellfish must include and distinguish
between wild and farm-raised fish and shellfish, as
required by the legislation.
Covered commodities are excluded from
mandatory country of origin labeling if they are an
ingredient in a processed food item. Examples of
covered commodities excluded under this provision of
the proposed rule would be bacon, orangejuice, mixed

nuts and fruit/vegetable party trays.
Food service establishments, such as restaurants,
lunchrooms, cafeterias, food stands, bars, lounges and
similar enterprises are exempt from the mandatory
country of origin labeling requirements.
Under the proposed rule, a covered commodity
can only bear a "United States country of origin"
declaration if certain criteria are met.

For beef, the covered commodity must be
derived exclusively from animals born, raised and
slaughtered in the United States, including animals that
were born and raised in Alaska or Hawaii and
transported for a period not to exceed 60 days through
Canada to the United States and slaughtered in the
United States.
For lamb and pork, the covered commodity
must be derived exclusively from an animal that was
born, raised and slaughtered in the United States.
Farm-raised fish and shellfish covered
commodities must be derived exclusively from fish or
shellfish hatched, raised, harvested and processed in
the United States.
Covered commodities forwild fish and shellfish
must be derived from fish or shellfish harvested in the
waters of the United States or by a U.S. flagged vessel
and processed in the United States or aboard a U. S.
flagged vessel.
In the case of perishable agricultural
commodities and peanuts, the covered commodities
must be derived exclusively from produce or peanuts
grown in the United States.
The proposed rule also outlines the requirements
for labeling products of mixed origin including products
produced both in foreign markets and in the United
States as well as labeling requirements for blended
products. Additionally, recordkeeping requirements for
retailers and their suppliers are outlined.
The full text of the proposed rule will be published
in the October 30 FederalRegister Comments may
be sent via e-mail to: cool@usda.gov or sent regular
mail to: Country of Origin Labeling Program; USDA
Agricultural Marketing Service; 1400 Independence
Ave., SW Stop 0249; Washington, D.C. 20250-0249,


no later than Dec. 29, 2003. Copies of the proposed
rule and additional information can be found

Finishing Cull Beef Cows on a
High-Grain Diet

Previous research has shown that feeding cull cows
a high-energy diet for 60 to 100 days can be profitable
depending upon the cost of grain in relationship to the
price of cows at the end of the feeding period. In this
Montana study, cull beef cows were allotted to a control
group (no implant) and a group that was implanted with
Synovex-Plus. The obj ective was to determine the
effects of implant, initial body weight (BW), and initial
body condition score (BCS) on feedlot performance
and carcass characteristics. Cows were fed 90 days
on a high-energy, 80-85% concentrate diet.
* Increased initial BW was associated with increases
in final BW, hot carcass weight, ribeye area, and
numerical yield grade. Average daily gain (ADG)
and backfat were not affected by initial BW.
* Initial BCS had no effect on any feedlot or carcass
trait except for an increase in backfat.
* Implant significantly affected all feedlot and carcass
characteristics except for backfat. Implanted cows
had 0.48 lb/d greaterADG 40 lb greater final BW,
40 lb greater carcass weight, 1.3 sq. in. larger ribeye
area, 0.27 increase in marbling score, and 0.24
numerically lower yield grade.
The authors concluded that feeding cull cows for
a period of time before marketing can enhance carcass
quality and may improve profitability. However, the
cost of gain may often be greater than ultimate sale price
of the cows. They added that it is important to consider
seasonality of cull cow prices and the price differential

between cull cow slaughter grades. In this study,
implanting clearly improved feedlot performance and
carcass characteristics (Funston et al. 2003. Prof. Anim.
Sci. 19:233).

Corn vs. Soyhulls as a
Supplemental Source of Energy
for Lactating Beef Cows

Previous research has shown that supplementing
cows in early lactation with high-starch grains (e.g.,
corn) may negatively impact digestion of the forage
portion of the diet, whereas supplementing with low-
starch feeds (e.g., soyhulls) does not interfere with
forage digestion. In this North Dakota study, 78 cow-
calf pairs, fed a basal diet of 75% grass hay, 25% wheat
straw, were allotted to four different supplemental
treatments during early lactation: 1) 10.5# dry rolled
corn (8% crude protein [CP]); 2) 8.1# dry rolled corn
plus 3.4# sunflower meal (8.9% CP); 3) 11.7# soyhulls
(8.9% CP); 4) 9.9# soyhulls plus 2.3# sunflower meal
(10.8% CP). All diets were equivalent in energy. On
July 25, diets were reformulated to meet the lower
energy requirements of late lactation. All cows and
calves were weighed every 28 days. At each weighing,
milk yield was determined on a sample of five cows in
each treatment.
There were no significant differences between any
of the treatments for changes in cow weight, cow
condition score, milk yield, or calfweight. These results
indicate that either corn or soyhulls are suitable as an
energy supplement for the quality of forage used in this
trial. Furthermore, the addition of sunflower meal as a
protein supplement had no effect on cow or calf
performance (Baumann et al. 2003. Proc. Beef Field
Day, Carrington Res. Center, North Dakota State Univ.,
Volume 26).
