GRAZING FOR PROFIT Consider the impacts of your decisions
Four Primary Process’s to Consider � � � Water Cycle Mineral Cycle Energy Flow Community Dynamics Resource Concerns � Soil � Water � Plant � Animal � Air � Human � Energy
Water Cycle
Mineral Cycle
Community dynamics is all species or populations living in an area Aggregate Stability
Energy Flow Through the Ecosystem Sun Heat Producers Heat Consumers Inorganic Minerals Decomposers Heat
Infiltration Runoff 3) Continuous Grazing 1) Pasture with 2) Rotational Longer Recovery Grazing Period
Rainfall Simulator Tilled w/ No-Till Residue 3” Grass 8” Grass
Manage Soil Temperature with Cover � 20 degree difference in area with cover of plant and residue versus tilled soil
When Soil Temperature Reaches (F degrees) : � � 140 130 Soil bacteria die, soil sterilization 100% of soil moisture is lost through evapo-transpiration 100 15% of moisture is used for growth 85% of moisture is lost 70 100% of soil moisture is used for growth

What Are The Benefits of Grazing Management? Producer Benefits � Increased production per acre- increased energy efficiency � Increased organic matter � More available water � Drought tolerance � Lower cost � Less hay needed � More cow comfort Society Benefits � Improved water quality- lower cost to purify water � Improved soil quality- cheaper than CRP and better soil � Reduced flooding � Less CO 2 emissions � Lower temperature of environment � More energy captured
Ending Height is very important!!!

Cool-season grass-clover pasture, 10 inches tall at grazing. 4. Roots equal top growth at grazing.
Reading the Land What’s the Grazing Prescription? � � � Recovery- Rest Disturbance- Impact Cover- Vegetative and/or Residue Fertility –Manure C: N Ratio 25: 1
Bale Grazing. Creep Grazing Hay � � Continue to get benefits of manure distribution outside of the growing season Creep Grazing allows growing animals more choice.

ORCHARDGRASS GRAZING RESPONSE Dr. Ray Smith Laura Schwer Tom Keene
Methods Two similar orchardgrass plants were chosen from greenhouse. � Both were managed the same for 6 months: � �Clipped ~once per month �Supplied with good fertility (N, P, K) and water
Methods � Left plant simulates continuous grazing. � Initially clipped to a 1 inch height � Then clipped weekly for the next 4 weeks at a 1 inch height � Right plant simulates rotational grazing. � Initially clipped to a 3. 5 inch height � Then clipped again at 3. 5 inches four weeks later � Time lapse photography started at the beginning of the fifth week (day 29) for both plants.
Day 1 (24 hours after clipping) 1” Continuous 3. 5” Rotational
Day 2 1” Continuous 3. 5” Rotational
Day 3 1” Continuous 3. 5” Rotational
Day 4 1” Continuous 3. 5” Rotational
Day 5 1” Continuous 3. 5” Rotational
Day 6 1” Continuous 3. 5” Rotational
Seasonal grazing: Buying light weight stockers in December, Selling heavy weights in August

Basic Steps to Improve Pastures � � Fertilize by soil test, hopefully most P and K provided by cycling nutrients through livestock Control weeds – hopefully out compete weeds or turn weeds into forbs by using high density short duration grazing or grazing multi-species livestock
Top Grazing Practices � � � Grazing Height Seeding Legumes High Density Short Duration Grazing Lime: P and K not N Fence � � Water Management Stockpiling tall fescue Multi-Species Grazing Timing: April 1, July 1 and Oct 1
Farm Considerations and Layout Corral as hub, fence for flow of livestock Determine “Acres per Paddock” for location of fence and water Topography ultimately determines location of Watering Facilities
BASIC PADDOCK LAYOUT 16 PADDOCK with 4 WATERING POINTS (funneling animals) Temporary fence Permanent fence Water point Permanent fence corral
Gate Arrangements 16’ gates 90 degree = 22. 5’ gate openings No post in center To layout stake with string in center where gates swing together
2 Gates Four fields if rotational grazed, bungy gates can be different widths
Trails commonly form between water source and feed area
Traditional Pond Potential Diseases � � � E-coli � Samonella � Coccidiosis � Leptospirosis � Foot rot Anthrax Brucellosis Erysipolis Other
Summary � � � Most Pastures need Recovery- Rest Disturbance- Impact a tool especially at beginning of growing season Cover- Vegetative and/or Residue most abused, how can you grow grass if you don’t capture energy Fertility –Manure management JUST DO IT!
