Introduction to Pasture Management ANSC 110 August 31, 2010
The basics… • Pasture is healthy for your animal • Sunshine • Room to roam, play, socialize with others • Allows for natural eating behaviors • Nutritious
The basics… • Properly maintained pasture: • Can provide adequate energy, protein, vitamins and minerals to maintain most animals • A cheap source of feed for your animal
What is a High Quality Pasture? • Characteristics - • Dense • Diverse • Weed-free (relatively) • Well-drained • Crumbly, porous soil • Palatable
Advantages of Pasture • Promotes normal healthy behavior • Providing space for play and exercise • Promotes social interaction • Reduces development of vices
Advantages of Pasture • Reduces likelihood of colic • Lowers incidence of gastric ulcers • Decreased incidence of chronic obstructive pulmonary disease (Heaves) • Increases bone mineral content in young horses
Advantages of Pasture • Can produce 1-4 tons of forage matter/acre/growing season • Reduces hay costs by approx. $60-100/month
Advantages of Pasture • Reduces fertilizer costs when manure spread properly during year • Pasture recycles nutrients from dropped manure • Reduces need to manage bedding from stalls and drylots • $avings
Advantages – Environmental Returns • Reduces erosion • Recycles nutrients • Supplies land surface for ground-water recharge • Provides an aesthetically pleasing environment for rural and residential neighbors
Disadvantages of Pasture • Some weeds, grasses, and legumes contain toxic compounds: • Weed examples: • Jimsonweed, yellow star thistle, pokeweed • Grass examples: • Tall fescue • Legume examples: • Aslike clover, red clover
Disadvantages of Pasture • Spread of gastrointestinal parasites • Infective stage of parasites shed in feces • Optimal conditions for larval development • High stocking rates increased risk of infection • Manure management, appropriate stocking density, and deworming important for horse health on pasture
Disadvantages – Pasture Associated Laminitis • Condition of the foot characterized by inflammation of the tissues connecting the hoof wall to the major bone of the foot • Severe cases may result in rotation of coffin bone • High prevalence in overweight animals • Hereditary trait in ponies
Creating a Quality Pasture • Things to consider… • Management of the animals • Grazing management • Pasture management • Timing • Utilize your growing season • Optimize the stocking rate
Horse Grazing Behavior • Time spent grazing varies • Weather • Forage availability • Alone vs. with pals • Flies • Age • Will consume approximately ~ 2 – 2.5% BW in DM on a daily basis
Horse Grazing Behavior • 40-80% time spent grazing • 9% of a horse’s time is spent walking • 5-10% time spent lying down • Primarily 3-4 hours before dawn • SELECTIVE GRAZERS
Grazing Management • Optimize forage available • Leave some for later. Avoid overgrazing. • Know when to graze, when to rest • Grazing Systems • Continuous • Rotational • Strip
Grazing Management • Periods of occupation • Recovery periods • Stocking rate and density • Paddock/pasture design • Climate considerations
Optimize the stocking rate • Stocking Rate - a measurement of the long-term carrying capacity of a pasture; the number of animals on the entire grazing unit for the entire grazing season • Stocking Density - the number of animals on a given unit of land for a specific amount of time (short-term measurement).
Pasture Management • Obtaining that optimal pasture requires management of the: • PLANTS • SOIL
Pasture Management • Species Selection • Pasture Ecology • Water requirements • Temperature • Plant anatomy/growth factors • Pest control
Pasture Management • Pasture Nutrition • Sunlight / Water • Nitrogen • Potassium • Phosphorus • Other nutrients required • Soil acidity (pH level) • TIMING!
Timing • TIMING IS EVERYTHING!!!! • Seeding • Grazing • Resting • Irrigation • Fertilization • Climate-dependent
Utilize your growing season • Different species of plants have different growth curves • Variety healthy pasture year-round
