Learn about the impact of feed price increases on horse pasture management, rotational grazing techniques, stocking rates, rest periods, and forage growth to maintain healthy pastures and reduce costs.

Horse Pasture Management • New Era: • Increase Feed Prices • Corn price 100 % increase ($2.50 to $5.00) • Wheat Price 200% increase ($3.50 to $10.00) • Soybeans 150 % increase ($6.50 to $14.00) • Reasons: • World Demand-Standards of Living Increases • Declining $ Value –makes our grain cheaper by 33% • Bio-fuels-Ethanol and Bio-Diesel
Horse Pasture Management • New Era Affects: • Expect increases in Hay Prices • Current Hay Prices for Western Dairy Hay-$265/ton • Local Hay Supply very low-Little Carryover • Diesel Fuel is $4 per gallon-costs more to harvest and transport • Competition for acres-corn, wheat, soybeans • Winterkill of alfalfa in some areas • Land values increasing 15-18% last 5 years-in central Wisconsin
Horse Pasture Management • Pastures for horses now need to provide more of the horses annual needs • Is it possible to graze horses on pasture from May-December? 8 months • Hay at $4-6 per bale in 2009 or forage costs of $2-3 per day for a horse

Grazing Formula Sunlight + Rain + Green Plants = Plant Growth Plant Growth + Grazing Animals = $$$ The Grazing formula involves: • What’s best for the grass • What’s best for the livestock • What moves you toward your goals!!!
Traditional Pastures are often “Continuously Grazed” This usually means: • Lower yields • Serious weed pressure • Erosion problems • General “poor” management
In Rotational Grazing... • Pastures are subdivided into smaller areas (or paddocks) • A portion of the pasture is grazed while the remainder “Rests” • Paddocks are allowed to: • Renew energy reserves • Rebuild plant vigor • Improve long-term production
Intensive Rotational Grazing... Involves a higher level of management • Greater paddock numbers • Shorter grazing periods • Longer rest periods
W S Many 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
Rotational Grazing • Pastures are subdivided into smaller areas (paddocks) • A portion of the pasture is grazed while the remainder “rests” Lane Rest allows pasture to: • Recover from grazing, • Rebuild energy reserves & plant vigor • Increase forage production
W W W W Management 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 Corral Lane
Strip Grazing Recommened for fall pasture since no regrowth occurs

How much forage is out there? Rule of thumb: Figure about 400 pounds dry matter per acre per inch of cool season pasture. L. Paine
The 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
Relationship of rest period to pasture mass during periods of rapid vs. slow growth Lbs. DM / acre Optimum Rest Period 0 5 10 15 20 25 Period of fast plant growth (days) 0 10 20 30 40 50 Period of slow plant growth (days)
Stocking Rate (animals/acre) • Can use formulas for actual numbers • Thumb rule; one 1000 pound horse per 2-4 acres • Intensive Rotational Grazing = one mature, non-producing horse to 1-1.5 acres • Traditional “Under-managed” pastures = one horse to 5-10 acres
Stocking Rate (animals/acre) • Can use formulas for actual numbers • Thumb rule; 1000 pound animal per 2-4 acres • Intensive Rotational Grazing = 1000 pound horse to 1-1.5 acres • Traditional “Under-managed” pastures = 1000 pound horse to 4-6 acres
Which will cause more overgrazing? The stocking rate of both paddocks is identical: 100 Animal Days per Acre. The effect on the paddocks will be much different.
How much do my animals need? Rule of thumb: Horses Figure 3 to 4% of body weight dry matter per animal per day. L. Paine
Pasture Needs Calculation • 1000 horse needs-3.5% of body weight • Pasture is 8 inches tall • Graze to 3 inches • 5 inches x 400 lbs/inch=2000 of DM forage • 2000 divided by 35 lbs(needs per day)=57 days of forage • Pasture can supply 2 months of grazing

FROST SEEDING Adding new seed to a pasture by broadcasting on frozen ground in early spring, letting frost & snow incorporate the seed.
Frost Seeding in Snow Frost Seeding
FROST SEEDING • Improves Pasture Quality & Yield • Lower Cost Than Annual Nitrogen Application ($9 vs. $42) • Works Best On Loams & Clay Soils or Fields With Natural Moisture • Clovers Recommended, Birdsfoot Trefoil & Certain Grasses Can Work
Horses & Pasture • A grass-legume pasture can produce enough to meet the maintenance requirements of most adult horses • In general, horses are more destructive to pasture than cattle • Horses are natural “nibblers”
Horses & Pasture A Pennsylvania study showed horses preferred: • Grasses over legumes • Bluegrass over taller grasses • Clovers over alfalfa and birdsfoot trefoil The study also showed that horses’ made satisfactory progress on all pasture mixtures
If at all possiblegraze cattle with horses Because: • It reduces parasitic infestation • Each will eat around the others’ droppings • It assures more uniform use of the pasture • Cattle will graze otherwise wasted feed
