4Grazing Economics
- Beef-Cow industry looks very profitable in
2000-2003 based on Cattle-Fax projections - Opportunity to reduce debt
- One of the common pitfalls is increased expenses.
- If income goes up and expenses also increase we
have lost a profit opportunity
5Grazing Economics
- Cow /calf economic factors are
- Reproductive efficiency
- Weaning weight
- Sales price
- Feed Cost
- Market Cycle
- Fixed Costs
6Grazing Economics
- Managed Intensive Grazing (MIG)
- Offers greater management Flexibility
- Comes at an added cost
- Fence
- Water systems
- Labor
- Higher level of management required
- Greater investment per animal
7Make it Profitable
- Stocking Rate Is Critical
- Goal is to maximize production per acre and
production per head - Greatest profits are not generated by the
greatest production - Economically optimum stocking rate will occur
somewhere between the point of maximum output and
maximum per head performance
8Calf gain under various grazing systemsIowa
State University
- Using a 100 cow herd for the analysis
- Return to operator labor, capital and management
per acre - Brome
- 99.53 w/high, 51.30 w/low intensity
- Mixed grass/legume
- 140 w/high, 119 w/low and 108 w/continuous
9Calf gain under various grazing systemsIowa
State University
- Two grazing intensities
- -high with one cow/calf pair per acre
- -low or continuous with 1.67 acres per cow/calf
pair - Two pastures-mixed legume and brome
10Calf gain under various grazing systemsIowa
State University
- Results
- -on mixed grass/legume, ADG was similar but gain
per acre was 100 lbs higher with MIG pasture - -on brome grass , ADG was greater for low
intensity but gain/ac was 60 lbs higher for MIG
pasture
11How Does Grazing Compete with Cropping Operations
and CRP
- ISU Adams County Demonstration Farm
- -- 13 paddock intensive grazing system with
cow/calf pairs was the most profitable option - --less intensive grazing was the 2nd most
profitable system - --CRP was third
- --One cropping option gave a positive return
12Importance of individual animal performance
- Stocker cattle rule of thumb
- It takes 150 lbs of gain for a stocker to cover
its costs -
- 200 lbs of gain returns 50 lbs of profit
- 250 lbs of gain returns 100 lbs of profit
13Many Pastures are Continuously Grazed
- This usually means
- Lower yields due to selective grazing
- Greater weed problems
- Potential for erosion problems in certain areas
-
- No management or poor management of forage
resource
14Rotational Grazing
- Pastures are subdivided into smaller areas
(paddocks) - A portion of the pasture is grazed while the
remainder rests - Rest allows pasture to
- Recover from grazing,
- Rebuild energy reserves plant vigor
- Increase forage production

15Management Intensive Rotational Grazing
Management Intensive Rotational Grazing (MIRG)
involves even greater numbers of paddocks and/or
subdivision within paddocks to increase amount of
rest and decrease days grazing each rotation

Lane
16Stocking Rate (animals/acre)
- Can use formulas for actual numbers
- Thumb rule 1000 pound animal per 2-4 acres
- Intensive Rotational Grazing 1000 pound beef
animal to 1-1.5 acres - Traditional Under-managed pastures 1000
pound animal to 5-10 acres
17Plan Use A Rotational Grazing System to Make
Money!!
- Make pasture foundation of your livestock
production system and use hay as supplemental to
the systems, not vice versa - Pasture 6 - 7 months/year in Southwest WI (April
15 - November 15) with minimal supplementation if
managed properly - Graze hay fields after youve secured your winter
feed supply rather than spending more time
money cutting hay - Stockpile some pastures beginning in mid summer
to use for late season grazing. Plan to stockpile
for 70 - 90 days prior to use so that quality is
acceptable
18Plan Use A Rotational Grazing System to Make
Money!!
- Plan grazing by our pasture seasons
- Spring (April - mid-June)
- Mid-summer (July - August)
- Late summer (September)
- Fall (October - snow)
- REST is a key component to maximize pasture
production - REST PLANT VIGOR MORE PRODUCTION
- Rotation results in better harvest efficiency
than continuous grazing (60-70 versus 30)
19The Rest Period
- Should vary according to plant growth
- In general, must increase as growth rate slows
- Relates closely to seasonal forage growth
- Need to rotate between paddocks every 3-6 days

23Plan Use A Rotational Grazing System to Make
Money!!
- Less hay to make, store feed out (or more hay
to sell!) - Lower feed costs with pasture-based systems
- Other benefits
- Vigorous pastures have fewer weeds
- Use rotation to develop a CLEAN calving area each
year - A more environmentally friendly system for SW
Wisconsins hills than row crops (less erosion) - Match forage supplies to herds nutrient demand
- More options for calves with excess forage/hay,
can carry calves longer on grass or stored
forages and capitalize on those cheap feeds and
better cattle prices at other times of year. Calf
price annual lows are typically in fall when
everyone weans and sells.
24Stretching the Grazing Season with Crop Residues
- Utilize Cornstalks
- 2-2 ½ acres per cow should get you 40-75 grazing
days - Weather will affect grazing conditions
- Cornstalks grazed directly after harvest are
highest in nutrients - Cattle will select grain first, then husk and
leaf and finally cob and stalk
25Use Nitrogen on Pastures
- Use of N in early spring stimulates grass growth,
especially for unimproved (bluegrass/quackgrass)
pastures - Use of N in mid- late June will stimulate summer
grass growth of taller pasture grasses
(orchardgrass, fescue, etc.) - Some folks use N in August on pastures that they
plan to stockpile for fall grazing - 50 -80 N/acre per application is typical and
adequate - Pastures with gt 40 legume may not need N
fertilizer
26Mineral and Salt
- White salt is not enough!!
- Mineral needs will change consider a different
mineral mix during winter hay feeding season. - Work with a nutritionist and test forages if
necessary to get an idea on appropriate mineral
mixes
27Soil Fertility
- Soil test every 3 - 5 years to monitor pH, P, K
- Apply fertilizer as needed
- Pastures will use applied N more efficiently if P
and K fertility is adequate - Maintain pH above 6.0 to keep legumes in mix
- P is important for root vigor of all pasture
species and supports N fixation in legumes
28Consider the New Fencing Technology
29Useful Life of Fencing Materials
30Fencing Cost
- One of the largest expenses in Grazing
- Many different options but some rules apply
- Have secure perimeter fence
- Use temporary or portable fence in cells
- Use the lay of the land to your advantage
- Be flexible in cell sizing
31Cost of Fencing
- Cost of quarter mile of fence(Source Iowa State
University ) - 48 woven wire, one barb-----------1.07/foot
- 5 barbed wire fence------------------0.83/foot
- High tensile 8 strand 12.5 gauge---0.76/foot
- High tensile 5 strand electric(12.5)0.57/foot
- Polywire fence(interior use only)--0.03/foot
- Cost of Pasture Renovation
- Many options
- Complete plowing, disking, drill and pack
- Interseeding using drill or special seeder
- Frost seeding

33Cost of Reseeding
- Most sources recommend frost seeding as the best
and most cost effective method of establishing
and improving pastures - With frost seeding the costs are primarily the
cost of the seed
34Cattle Pasture
- Protein and energy supplements are usually
unnecessary - Provide free choice salt AND minerals
- Be careful not to let cows and heifers get too
fat. Fat cows will have problems at breeding
time, fat heifers will produce less milk as cows
35What about Equipment
- One of the primary benefits of Grazing is the
Machinery necessary - Many producers limit themselves to a
- Tractor with loader
- Manure spreader
- One hay making set of equipment(square bales or
round baler)
36Time Requirements
- Remember Cattle Need to be Moved
- Make sure you have the time and labor to move
cattle to new paddock - You must learn to know when is it time to move
them - Timing will vary with the amount of available
pasture
37Winter Feed Supply
- Winter feeding often accounts for 70 of the
total feed cost for a beef cow-calf operation - As a grazer our goal is to reduce the amount of
feed brought to the cow and to have the cow go
get it herself - this reduces costs
- gets the manure in the field
38Wintering Costs
- Stockpiling forage is recommended
- Set pastures aside for late fall and winter
grazing - Consider corn stalk grazing or other refuse
grazing - Consider windrowing in Nov and let the cows eat
the forage out of the windrow when snow is present
39Reducing Winter Feed Cost
- Purchase cheap hay not suitable for dairy and
horse owners during the summer - Substitute cheap corn and oats for forage
- Remember 10 lbs of a 50/50 corn oats mix is only
.30 with today's grain prices - Look at cheap alternatives, i.e. potato waste,
sweet corn silage, candy waste
40Cutting Winter Feed Cost
- Figure out a way to feed a cow for 100 or less
from Nov-April - Have some pasture available for April 1 grazing
- Try to keep the manure out of the feeding area
and in the pastures where it will fertilize next
years forage supply
41Grazing Management Tips
- Learn To Manage Your Pastures
- Avoid over or under grazing
- Apply fertilizer as needed (take a soil test)
- Re-seed pastures if necessary
42Grazing Management Tips
- Commit Yourself Totally To Making It Work
- Make The Transition Gradually
- Solicit A Lot Of Advice, But Make Your Own
Decisions - Stay Flexible And Keep Investments Low
- Plan, Plan, Re-plan
43Make good quality hay
- Maintain soil fertility and pH levels
- Harvest at proper growth stage to optimize yield
and quality--for beef cattle, you can cut alfalfa
at 1/10th to 1/2 bloom and make good quality hay
while maximizing tonnage
44Consider storage options for hay
- Dry matter losses of 10 - 50 are common in round
bales stored outside - Digestibility also declines with weathering
spoilage - Cover and elevation from soil (i.e. moisture)
contact is important - Barn storage can be cost effective
45(No Transcript)
46Barn Storage Example
- 1000 bale _at_ 85 dry matter and 54 digestibility
- (1000 x .85) x .54 459 digestible dry matter
at baling - Stored outside
- expect 30 dry matter loss, 45 digestibility
- (850 x .70) x .45 268 digestible dry matter
- Effective loss 1 (268/459) 42
47Barn Storage Example
- 50 x 100 barn with 14 sidewalls
- cost 20,000 5,000 ft2 _at_ 4.00/ ft2
- Annual costs
- Depreciation 20,000/20 years 1,000
- Interest (10 of ave. value) 10,000 x .10
1,000 - Taxes Insurance (3) 20,000 x .03
600 - Total Annual Cost of building 2,600
48Barn Storage Example
- Assumptions
- Hay valued at 60/ton of dry matter, storage _at_
85 moisture. - Effective dry matter digestibility loss 42
if stored outside. - Bales are 5 diameter x 4, weigh 1000 and are
stacked 3 high (on end), so that 240 tons can be
stored in barn. - Total dry matter stored 240 tons x .85 204
tons - Forage saved 204 tons x .42 86
tons - Value of forage saved 86 tons x 60/ton 5,160
- Net annual savings 5,160 - 2,600 2,560
49If You Must Store Round Bales Outside...
Bright sunny location, no trees or other objects
to slow drying after rains Storage area located
on gently sloping, well drained
site Hay/soil contact avoided by placing bales
on rock, wooden pallets, etc. Fire risk can be
reduced by storing hay in more than one location
by maintaining a no vegetative zone of at least
3 feet around the storage area
No objects nearby to attract lightening Flat
ends of bales butted tightly together Bale rows
run up down slope with north/south orientation
a southern orientation is best High bale density
resists water penetration Tops sides of bales
can be protected from rain with a number of
different types of covers.
