Study Notes
Types of Grazing
- Rough mountain/hill grazing involves permanent grassland on peaty, difficult-to-cultivate soil, which can be improved by liming and reseeding.
- Leys are temporary grasslands with variable botanical composition, medium stocking rates, and production levels.
Grass Growth Phases
- Vegetative phase: tillers form
- Elongation phase: stem growth occurs
- Reproductive phase: seed head emerges, and growth slows down
Grass Quality
- Palatability: measures the taste of grass, affecting grazing preference and intake
- Productivity: measures the quantity of herbage produced, with higher productivity providing more available for grazing
- Digestibility: proportion of food assimilated vs. consumed, crucial for livestock nutrition
- Dry Matter (DM): remaining matter after water removal, impacting nutritional value
- Dry Matter Digestibility (DMD): percentage of dry matter digested by animals
- Dry Matter Intake (DMI): amount of feed consumed excluding water content
Seed Selection
- Options include Perennial RyeGrass, Italian RyeGrass, White Clover, and Red Clover for different grazing needs
Grazing Methods
- Paddock Grazing
- Strip Grazing
- Block Grazing
- Zero Grazing
- Creep Grazing
- Mixed Grazing
- Extended Grazing
Livestock Units
- 1 Livestock Unit (LU) = 12 tonnes of herbage annually, used to measure grazing needs
Silage and Hay Production
- Silage production: fermentation of grass for preservation, affected by factors like pH, DM%, and DMD%
- Hay production: dehydration of grass for preservation, inhibiting microbial activity
Silage Production Steps
- Field preparation
- Cutting at the vegetative stage
- Wilting
- Chopping
- Compacting
- Covering with polythene
