Study Notes
Livestock Units and Herbage
- One Livestock Unit (LU) is equivalent to one dairy cow.
- Annually, one Livestock Unit is associated with 12 tonnes of herbage.
Clover Varieties
- Red Clover is recognized for its long growth period.
Grass Plant Functions
- The primary role of grass plant roots is to anchor the plant and absorb water and nutrients.
- Grass leaves are essential for photosynthesis and transpiration.
Grass Production Terms
- The term "productivity" refers to the amount of plant material produced by grass that is available for grazing.
- Dry Matter Digestibility (DMD) measures the proportion of dry matter in grass that can be digested by an animal.
Dry Matter Considerations
- Dry Matter Intake (DMI) quantifies the amount of feed consumed by animals excluding water.
- Palatability assesses how pleasant the grass is to taste, influencing livestock consumption.
- Digestibility impacts the efficiency of nutrient assimilation in grazing animals.
Grass Characteristics
- Italian RyeGrass is characterized by its growth rate during colder months compared to Perennial RyeGrass.
- The grass plant's stem supports upright growth and new tillers.
Measurements and Management
- Livestock Units are relevant to herbage availability; herbage requirements increase proportionally with livestock units.
- Permanent grassland can sustain livestock throughout the year when managed appropriately.
Nutrient and Dry Matter Analysis
- Dry matter signifies the grass weight after removing water content.
- Dry Matter Digestibility (DMD) indicates the proportion of dry matter digestible by an animal.
Evaluating Grass for Livestock
- Palatability is critical as it affects the livestock's willingness to consume grass.
- Productivity in grassland is measured by the quantity of herbage produced for grazing.
