Introduction
The following identifies and quantifies 10 of the most profitable
management practices for cow-calf production. The techniques were
evaluated in terms of net economic benefit (revenue generated by a
practice less the cost of implementation). Additional comments are
included which describe the impact these management practices may
have on the production system. The physical and economic impact of
the procedures were estimated using assumptions based on a typical
Ontario herd. The results should apply to the majority of those herds
which bear a close resemblance to the example herd. However, managers
must interpret the results with regard to their own specific production
system. The information presented is based on a broad range of sources.
The management practices are presented in approximate order of estimated
economic benefit.
Assumptions
- cow herd calving in spring
- calves weaned in the fall and marketed to feed lot sector
- average 200 day adjusted weaning weight of 550 lbs
- average lbs weaned per cow exposed of 500 lbs
- price received for calves is $1.10/lb
- economic benefit is based only on the increased weight and/or
value of the calf crop available for marketing; other benefits are
listed for interest

Crossbreeding system
to utilize heterosis (hybrid vigour)
- improvement in conception rate, calf survival
- increased weaning weights and cow longevity
- cumulative 15-25% increase in lbs weaned/cow exposed
- $83 - $138 per cow exposed
Costs
- variable; approximately $0 - $40 per cow
- potential of increased management and more record keeping
- potential of increased number of breeding pastures
Net Return: $83 - $98 per cow exposed
Comments:
- adequate planning required to minimize potential problems, for
example calving ease
- not necessary to use breeds with large differences in mature size
- largest benefit comes from use of cross bred cows
- this practice complements # 2 below

Crossbreeding system
to produce a premium feeder calf
Benefits
- a large frame X medium frame calf with a good muscle:bone ratio
commands a premium of approximately 15 %, compared with straightbred
medium frame calves
- premium of 10% compared with straightbred large frame breed calves
- $70 - $110 per cow
Cost
- variable, approximately $20 - $40 per cow
- more record keeping and overall management
Net Return: $ 50 - $ 70 per calf marketed
Comments:
- important considerations for breeding stock selections include
muscling and finish weight
- benefits from selling premium quality calves should be combined
with production system benefits from practice #1; total economic
benefit from crossbreeding is $100 to $170 per cow exposed
- use breeds which complement each other for key traits
| Top of Page |
Compressed Calving Season
Benefits
- more early born calves results in heavier average weaning weight
- reducing calving season from 120 to 90 days would result in an
average weaning age increase of 30 days, or about 65 lbs per calf
( $71 per calf
Cost
- $10 - $40 per cow; more for some situations
- additional feed inputs, herd health program, cow culling, breeding
soundness evaluation of bulls
Net Return: $30.00 - $ 60.00 per
Comments:
- more uniform calf crop to market
- facilitates effective management
- requires careful attention to herd nutrition, health management,
fertility of breeding stock
| Top of Page |
Castrate at an early
age and implant
- market premium of $4.00 - $6.00 per cwt for steers versus intact
males
- implant increases weaning weight 15 - 25 lbs over non-implanted
steer (equivalent to weight of intact males
Cost
- $5.00/hd ($3.00 castration + $2.00 implant)
Net Return: $17.00 - $28.00 / male marketed &
Comments:
- minimal stress and health risk with early age castration versus
older age

Creep feed calves when
pasture quality is poor
Benefit
- increase in weaning weight of 40 - 60 lbs compared with non supplemented
calves
- efficient use of supplementary feed when pasture limited ie. 6
lbs feed : 1 lb of extra gain
Cost
- 300 lbs creep for 50 lbs gain
- 300 lbs at 6 c/lb = $18
Net Return $32 / calf marketed
Comments:
- economic benefit from creep feeding decreases as pasture quality
increases
- unlimited high energy creep may impair udder development of some
small/medium frame heifer calves; may decrease price/lb for small/medium
frame calves
| Top of Page |
Use of a herd sire with
known, superior genetics for preweaning growth
Benefits
- increased weaning weights, compared with average or inferior sire
- known genetic potential reduces risk in selection
- for a + 20 EPD bull, 20 lbs increase in weaning weight per calf,
relative to breed average
- for a + 20 EPD bull, relative to a non-evaluated bull (example
- 20 EPD equivalent), 40 lbs increase in weaning weight
Cost
- $300 - $500 price premium for herd sire
- $4.00 - $6.70 per calf sired
Net Return : $15.00 - $18.00 per calf marketed, compared with
calves of breed average sire.
Net Return : $30.00 - $36.00 per calf marketed, compared with
calves of non-evaluated sire (example used is assumed to be the equivalent
of a -20 EPD for Weaning Gain)
Comments:
- EPD = Expected Progeny Difference (within breed
- ABC = Across Breed Comparison (among breeds
- weaning weights increase with growth EPD of sire
- tested sires also have been evaluated for other traits
- assumes each bull used for 3 years, breeding 25 cows/year
- superior genetics transmitted to replacement heifers
- higher salvage value will offset at least part of purchase price
premium

Dehorn calves at a young
age
Benefits
- properly dehorned calves receive a price premium of $3.00 - $5.00
per cwt compared with horned calves
- early dehorning imposes less stress on calf and avoids weight
loss incurred closer to sale date
Cost
Net Return : $13.50 - $24.50 per calf sold
Comments:
- polled breeding stock (with superior genetics) can minimize the
need to dehorn
- degree of stress and risk of health problems associated with dehorning
increases with the age of the calf
| Top of Page |
Improved Grazing Management
Benefits
- improved calf and cow nutrition resulting in increased weaning
weights and higher conception rates
- average improvement of 15 lbs weaned/cow exposed ( $16 per cow
Cost variable depending on management practice employed
- capital cost of extra fencing for grazing management amortized
over 15 years is approximately $1.50 - $2.50 per cow per year
Net Return: $12.50 - $14.50 per cow
Comments:
- improved cow condition going into winter
- improved carrying capacity of land base
- costs used are for high tensile electric
- assumes good soil fertility management
| Top of Page |
Ration Formulation
Benefits
- improved reproduction
- improved weaning weights
- increase of 10 lbs weaned per cow exposed
- improved growth of female replacements
- $1.00 - $2.00 per cow for feed analysis
Net Return: $10.00 - $12.00 per cow exposed
Comments :
- improved allocation of feed resources
- selection of appropriate feed supplements, including minerals
- feedback on forage management

Pregnancy Checking
Benefits
- culling of open cows reduces feed consumed by non-productive females
- early identification of open cows allows them to be marketed to
best advantage
- $15 - $20 per cow
Cost
Net Return: $13.00 - $17.00 per cow
Comments:
- timely pregnancy checking allows the detection of problem situations
earlier
- open cows may be sold immediately or fed to a higher level of
condition before marketing
- benefits from pregnancy checking decrease as conception rate increases

Background for Ten Top Management Practices
1. Crossbreeding To Utilize Hybrid Vigour
- the improvement in performance of crossbred cattle relative to
their parents (ie. hybrid vigour) for conception rate, calf survival,
growth to weaning and milk production are exceptionally well documented
in scientific literature
- crossbred cows wean approximately 15 % more lbs of calf per mating
opportunity due to higher conception rates, increased calf survival,
and increased milk production
- crossbred calves wean about 10 % heavier than comparable straightbreds
due to a higher survival rate and increased preweaning growth
- when considering breeds which are very diverse in performance
parameters, some "breed effects" will overshadow heterosis
for preweaning growth and milk production, but the most significant
benefits (conception rate and calf livability) will still be realized
- additional revenue calculated as:
500 lbs/cow X $1.10 X 115% = $83
to 500 lbs/cow X $1.10 X 125% = $138
- costs include fencing to provide additional breeding pastures
or purchase of F1 replacement heifers
- net return is:
$83 - $20 = $63
to 138 - $40 = $98 on a per cow basis
- reference OMAF Factsheet "Crossbreeding Systems For Commercial
Beef Production" 420/36
2. Crossbreeding To Produce a Premium Feeder Calf
- premiums exist for crossbred large X medium frame feeder calves
with a good muscle:bone ratio in most Ontario markets
- specific crosses receive larger premiums in some markets
- both straightbred medium frame and straightbred large frame calves
are discounted
- average premium is estimated to be $15/cwt, based on a survey
of Northern Network Feeder Sales
- costs are the same as for (1.) above
additional revenue calculated as:
$605/calf X 115% = $695
$695 - $605 = $90
- net return is
$90 - $20 = $70
to $90 - $40 = $50
- adding the benefits from improved production due to heterosis
and the market price premium gives a huge economic advantage to
crossbreeding ($100 to $170 per cow); it is an essential component
of commercial cow-calf production
3. Compressed Calving Season
- example deals with a herd with a typical calving spread of 4 months
- management can applied fairly easily to reduce this by 30 days
- costs include lab analysis of forages, purchase of some extra
feed supplements, pregnancy testing and some cow culling
- assumes a "normal" (bell curve) distribution of calving
dates>
- assumes the average calving date is moved up by 30 days
- additional calf weight is 30 days X 2.25 lbs/day = 67.5 lbs
- additional revenue is
65 lbs X $1.10 = $71.50 per calf
- net return is
$70 - $40 = $30
to $70 - $10 = $60 per calf
Reference: OMAF Factsheet "Breeding Season Management"
420/10.
4. Castrating At An Early Age And Implanting
- assumes average price premium of $5/cwt for steers relative to
intact males
- assumes that the 5% reduction in preweaning gain of steers relative
to bulls is compensated for by the hormonal implant
- assumes minimal health risk if calves are castrated properly at
a young age
- additional revenue is
$.05 X 550 lbs = $27.50
- cost is $3/head for castration plus $2/head for implant
- net return is
$27.50 - $5 = $22.50 per calf marketed
Reference: OMAF Factsheet "Castration Of Beef Calves"
420/10.
5. Creep Feeding When Pasture Quality Is Poor
This can be a very profitable management technique when applied in
anappropriatesituation. Conversion of creep to extra gain is quite
efficient when pasture is limited in quantity and/or quality (example
conversion of 4-6 lbs feed to 1 lb of gain). Profit is determined
by the cost of creep feed relative to the price for calves. If pasture
is good, then calves will tend to substitute creep for pasture, reducing
the economic efficiency of creep feeding. Conversion of creep to extra
gain may increase to 17:1.
Reference: OMAF Factsheet "Creep Feeding Beef Calves" 420/50.
6. Use Of A Herd Sire With Superior Growth Genetics
This really breaks down into 2 stages:
- use of a sire with knowngenetic potential (applied risk management)
- what is the degree of genetic superiority for growth (balancing
growth potential with other traits ie.calving ease, milk etc.)
To evaluate this practice, we have to compare the expected performance
of calves from the superior sire to calves from a sire with a lower
level of genetic merit. How high and low do we go? I have used a bull
with a Weaning Gain EPD of +20 lbs, and compared him with an average
bull of the breed (EPD of 0), and also with a bull with -20 EPD for
Weaning Gain.. The negative bull would represent the down side of
choosing a non-evaluated bull.
Reference: OMAF Factsheet "Ontario Bull Evaluation Program"
420/41.
7. Dehorn Calves At A Young Age
The example assumes that the dehorning is done correctly, with minimal
stress, to young calves. It assumes that sale weights are not affected
by the procedure, which is reasonable if things are done "right".
Price premiums are from major stocker sale results in Northeastern
Ontario from 1991, 1992 and 1993.
Reference: OMAF Factsheet "Dehorning of Beef Calves" 420/20.
8. Improved Grazing Management
Figure for improvement in lbs calf weaned/cow exposed from analysis
of Red Meat II Herd Health data by Dave Alves, OMAF. Costs for implementing
more intensive grazing management are for subdividing a 50 acre pasture
into 6 paddocks using 2-wire permanent electric fence. Reference for
costs from "Farm Fencing Systems" by Mark Leahy, OMAF.
Reference: OMAF Publication 19 "Pasture Production"
9. Ration Formulation
Increase in lbs weaned /cow exposed from analysis of Red Meat II
Herd Health survey by Dave Alves, OMAF. Cost based on current lab
fees, and assuming 2 feed tests per year. Also assumes that ration
formulation service is available at no cost to the producer.
Reference:
OMAF Factsheet "Basic Beef Cattle Nutrition" 420/10
OMAF Factsheet "Beef Cow-Calf Nutrition" 420/50
10. Pregnancy Checking
This can be combined with other management practices ie. parasite
control, re-tagging etc. to reduce # of trips through the chute. Veterinary
exam of problem breeders etc. at this time can be very helpful. In
some cases it is better to feed out empty cows to a higher weight
and flesh condition to obtain a higher selling price
