    Study Notes

    Grassland Types

    • Rough Mountain/Hill Grazing: Characterized by less accessible grazing areas, typically with diverse vegetation suited for paddocks.
    • Permanent Grassland: Maintained over long periods with perennial crops, supporting sustainable livestock rearing.
    • Leys: Temporary fields often established for specific grazing or crop rotations.

    Grass Characteristics

    • Palatability: The taste quality of grass, indicating how desirable it is for livestock.
    • Productivity: Reflects the volume of herbage produced, affecting availability for grazing.
    • Digestibility: Represents the fraction of food that can be absorbed and utilized by livestock compared to what is ingested.

    Nutritional Measures

    • Dry Matter (DM): Represents solid content in feed after moisture removal.
    • Dry Matter Digestibility (DMD): Percentage of DM that can be digested.
    • Dry Matter Intake (DMI): Volume of feed consumed by livestock, not including water.

    Grass Plant Anatomy

    • Roots: Absorb water/nutrients, anchoring the plant.
    • Stem: Supports upright growth, facilitating new tiller development.
    • Leaves: Conduct photosynthesis and assist in water management via transpiration.
    • Inflorescence: Houses the reproductive structures; wind-pollinated and transforms into seed heads post-fertilization.

    Seed Selection

    • Perennial Ryegrass: Ideal for long-term pastures, good for livestock due to high productivity.
    • Italian Ryegrass: Fast-growing, often used for quick forage but has a shorter lifespan compared to perennial varieties.
    • White Clover: Beneficial for nitrogen fixation and improving soil health.
    • Red Clover: Excellent for livestock feed, enhances soil nutrients, and supports biodiversity.

    Livestock Units (LU)

    • Measurement of grazing capacity; 1 LU equals one dairy or suckler cow.
    • Calculation for grazing needs: 1 LU requires 12 tonnes of herbage annually.
    • Classification of Cattle:
      • Dairy/suckler cow = 1.0 LU
      • Yearlings = 0.6 LU
