Beef/Cattle Extension Program
Cows which are adapted to my environment and still
produce calves desired by the customer
by John Paterson, Extension Beef
Specialist, Montana State University, Bozeman
Introduction:
Several beef cattle industry leaders were asked to
respond to this question "How do we produce calves the
customer wants as well as maintain cows which are matched
to my ranch environment?" This article summarizes
their responses as well as a review of articles they
have recently written.
Current Challenges:
Dr. R.J. Lipsey, CEO of American Simmental Association
suggested that ranchers desire a cow herd with 1) low
costs (or at least controlled costs), 2) reasonable
performance (minimal dystocia but explosive growth of
calves), 3) cull cows with value, and 4) market demand
for the calves (top of market and/or everybody wants
your calves).
In 1985 the average rancher spent $267 a year to maintain
each cow in his herd. By 1995 cash costs increased
to $322 per cow and could reach $357 by 2002.
This expense places today's cash costs fully $90/cow
higher than 15 years ago (up 34%; Brink, 2001).
In 1985 the breakeven cost for a 450 lb weaned calf
was estimated to be $.67/lb compared with $.90/lb for
that same 450 lb weaned calf in 2001. Duane Griffith
from Montana State University has tracked 60 Montana
ranches for the past decade to determine costs of production
and profitability. Table 1, shows the differences
between the top and bottom 25% of producers in this
database.

Griffith, MSU Department of Ag Economics and Economics
These data reveal that the top 25% of ranches in this
survey could produce a calf for approximately $.50/lb
while the bottom 25% of the ranches required $1.13/lb
to produce a calf. Expressed another way, the
top 25% of ranches were making a profit with their calves
($135/cow) compared with a significant loss for the
bottom 25% of ranches (-$223/cow).

How is the money spent in maintaining a cow?
The following table presents a generalized accounting
for yearly cash expenses.

The largest expenses were for feed (60 % of total).
Brink (2000) believes that operating a profitable cowherd
breaks down into following three basic rules:
-
Rule 1. Hold your annual cow-carrying costs to
$300 per cow (cash expenses) or less,
-
Rule 2. Keep your calf-crop weaned calf-crop percentage
at 88% of exposed cows or higher,
-
Rule 3. Wean calves that are average or above
for weaning weight (at least 475 lbs.).
Biological Factors Influencing Profitability.
The profitability of a cowherd is directly related to
the reproductive rate of the herd (Hutcheson, 2000).
Although feed costs play the major part of overall cow
costs, keeping a beef cow in adequate body condition
at calving has been shown to have a large impact on
reproductive efficiency. If we assume that a beef
cow needs to be in moderate body condition at calving
(score of 5), then we can predict how much feed will
be necessary if we also understand the relationship
between cow weight and frame size (Table 3).

Hutcheson, 2000
A cow with a frame score of 5 will weigh approximately
1175 lbs at a body condition score of 5 while a frame
score 8 cow will weigh 1400 lbs in the same body condition.
The main reason for getting a cow into a body condition
score of 5 at calving is so she will have a high probability
of rebreeding within 90 days. Cows in adequate
body shape at calving will have the best chance of rebreeding
and producing a calf each year (Table 4).

How does frame score influence the amount of hay required
to raise a cow from a body condition score of 4.5 to
5.5 during the last three months prior to calving?

A cow with a frame score of 8 with a body condition
score of 4.5 will require at least 6% more hay than
a cow with a frame score of 6 and a similar body condition
score.
How does your cowherd production compare to what
the industry is requesting? Green and Dolezal
(2000) summarized the desired reproductive, growth and
carcass traits, which were proposed by the late Robert
Taylor from Colorado State University (Table 6).

Dr. Taylor suggested that a mature cow should weigh
between 900 and 1300 lbs. (editorial observation:
I suspect many ranchers have mature cows that weigh
more than 1300 lbs). With regard to feedlot
and carcass requirements, it is interesting to compare
the results of the 2000 Ranch to Rail program sponsored
by Utah State University Extension (Zobell and Chapman,
2000) to this table. The following table summarizes
the performance of 144 steers from 21 ranches located
throughout Utah.

Zobel and Chapman,
(1999-2000 Utah Ranch to Rail Summary Report, USU
Extension).
Seventy percent of the calves gained more than 3.0
lbs/day while slightly more than 9% gained less than
2.5 lbs/day. Seventy two percent of the steers
graded choice or better with an average yield grade
of 2.10. But, fifty-two percent of the feeder
cattle had a negative return and ranged as high as a
negative $159 loss. However, 48% of the cattle had a
positive net return and ranged as high as $81/head.
If the industry is seeking more consistency in types
of cattle produced, then these results are a good example
of the variation that exists within the industry and
that there is still opportunity for improvement in both
feedlot and carcass performance.
Recently, the NCBA (2001) recommended several goals
for making beef a better product. Among the recommendations
were:
-
Eliminate USDA Standard-grade carcasses
-
Develop and implement a voluntary, industry-driven
and standardized electronic ID system
-
Develop an information system that allows each
producer to conduct a quality audit of his or her
own cowherd.
-
Continue to improve the eating quality of beef.
What are the reasons for not consistently providing
cattle to meet the specifications outlined in Table
6? Green and Dolezal (2000) suggested that the
reasons for inconsistency of the product has included:
-
Too much emphasis on matching the cow to the production
environment vs. matching the calf to the marketing
environment,
-
Fierce pride in producer individuality and independence
vs. strategic alliances and cooperative relationships,
-
Commodity based marketing vs. value based marketing,
-
Consumer preference vs. producer preference, and
-
Systematic crossbreeding vs. mongrelization of
the cowherd.
The value of heterosis in a crossbreeding program
has been known for many years, and the additional
return has been estimated to be between $50 to $100
(Ishmael, 2000). However, the quote by Ishmael
that crossbreeding "may be like managing a three-ton
gorilla in a creep feeder represents the attitude of
many ranchers". Why? Field and Cundiff (2000)
summarized the thoughts of the late Bob DeBaca who believed
that the reason many crossbreeding programs failed was
because:
-
The overuse of individual beef cattle breeds that
have too much in them- too much growth, milk, birth
weight or mature size.
-
The use of poor quality bulls in a crossing system
that did not yield desired results.
-
Seedstock producers failed to develop the expertise
and service orientation to assist their clients
in development of effective crossbreeding programs.
As an example, Harlan Ritchie from Michigan State
University describes a common breeding scheme, often
mistaken for planned crossbreeding. It is using a Continental
bull on some English cows cross breeding seasons and
crops of replacements. The percentage of the Continental
blood in the females rises to the point the producer
figures he needs an English bull. So, the biological
type of the calf crops swing from extreme to extreme
with everything in between, making it difficult to optimize
either production or marketing (Ishmael, 2000).
On the other hand, Dr. Jim Gosey from the University
of Nebraska was recently quoted to say "Many commercial
herds have stacked black bull on top of black bull and
have become high percentage Angus herds; herds which
have lost heterosis and have also lost retail product,
yield, muscle and pay weight" (Peck, 2001).
So how do we get to where we need to be?
Dr. R.J. Lipsey, responded that there are at least six
areas to concentrate breeding efforts on:
-
The herd needs high fertility females (high puberty,
high re-breeding and great longevity with low maintenance
requirements and environmentally adapted.
-
Respectable growth of calves with at least 25%
Continental blood
-
Respectable carcass values; (70% choice; 70% yield
grades 1 & 2; no out cattle
-
Convenient cattle; polled, quiet disposition,
pigment, frame, teats/udder, eyes, feet and easy
to replicate.
-
These cows will be crossbreds just like 100% of
the sows and hens in the U.S.
Specifically, ways to achieve these goals would be
to purchase replacement females and breed to terminal
bulls such as an Angus x Waygu (a cross for high marbling)
or Simmental or Gelbvieh x Angus for all purpose
calves, or Charolais x Piedmontese for a lean market.
According to Don Schiefelbein the executive director
of the American Gelbvieh Association "What's so difficult
about branding a hybrid, documenting the performance
and parentage, then offering it to commercial producers
in a simple, easy-to-use system (Ishmael, 2000
A producer needs to stabilize the ideal percentages
of breeds you need by purchasing, contracting or making
the sires yourself. Examples would be SimAngus,
Balancers (Gelbveih x Red Angus), Leachman Stabilizers
(1/4 Simmental, ¼ Gelbveih, ¼ Angus and ¼ Hereford)
or Rangemakers (Red Angus, South Devon and Continental).
The key is to make it easy and maintain at least 70%
of maximum heterosis and use one composite breed.
Breeding plans must be developed, by geo-climatic region,
for matching of breed resources to environments.
Seedstock suppliers (of both maternal and terminal sire
lines), commercial multipliers, and feedlot professionals
must become better integrated and aligned to make use
of value-added genetics (Green and Dolezal, 2000). The
speed at which the beef industry is changing is breath
taking. It would appear that one of the areas
which has the greatest opportunity to add profitability
to a cowherd is the use of planned crossbreeding to
meet both maternal requirements for your environmental
conditions and also provide calves with excellent growth
and carcass characteristics for the feedlot and packing
plant segments.
