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

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
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
Diet Selection of Livestock a A mixture of grass and legumes b Woody material
Pasture Types • Kentucky bluegrass • Very palatable and nutritious • Will withstand close grazing • Produces high-quality turf • Produces less forage per acre then other grasses • Grows slow during hot dry weather
Pasture Types • Orchard grass • If managed, is as palatable and nutritious as bluegrass • Will withstand closer grazing than other tall grasses • Produces more forage per acre then bluegrass
Pasture Types • Legumes • Any legume that is adapted to your area can be used successfully • Are higher in protein • Grow when grasses are going dormant • Nitrogen fixing capacity reduces fertilizer costs Some suggest using only one grass and one or two legumes in a mixture
Grazing Management Tips • For rotational grazing to be successful you must be flexible • If you don’t want to make hay during periods of rapid forage growth, move animals faster • Provide free choice salt & minerals
Grazing Management Tips • Avoid over or under grazing • Clip pastures regularly during the growing season • Drag pastures with a chain link harrow at least once per year • Apply fertilizer as needed (take a soil test) • Re-seed pastures if necessary
