why is Permanent grassland?
Leaves develop on grass and stem remains near the base
What is the vegetative stage?
Refers to taste - how appealing the grass is!
What is palatability?
measurement of livestock grazing.
What is a livestock unit?
High in protein and carbohydrates
High palatability, productivity (high Sr) and
Digestibility (high DMD)
Don’t need to reseed
Good tillering ability
Advantages of what grass species?
What are advantages of PRG?
The number of animals grazing a certain area of land
Why is the meaning of Stocking rate
Stem begins to grow, lengthens between the upper nodes and seed head starts to emerge
What is the elongation stage?
the ability of a grass to produce large amount of herbage.
What is productivity?
division of the land into parts that are of equal size.
What is paddock grazing?
Crossed to produce plants with hybrid vigour (best traits from both)
What id hybrid ryegrass?

What is a ley?
Adding N fert, rolling the grass, topping land and grazing sheep to 4cm encourages this?
The matter remaining in a sample of food after the water has been removed.
Meaning of dry matter (DM)
21 days - 3 weeks
How long does grass re-growth take
combination of different species of grass and clover.
What is a seed mixture?
Gorse, bent grass and moor grass are all examples
What are examples if rough mountain species?
The development of side shoots
What is tillering?
The amount of feed an animal consumes excluding its water content.
What is the meaning of DMI?
stock have access to all grazing land over one continuous area for the grazing season
What is set stocking?
swards that have a variety of plants - typically a mix of grasses, legumes, and herbs.
What are multispecies swards?
Italian RG, PRG and clover are examples of these
What are examples are permanent and ley grassland species?
Seed head develops and the stem becomes fibrous and strong enough to support seed head
What is the reproductive stage
represents the proportion of food that can be potentially digested by the animal
What is the meaning of digestibility?
A software package used to track the grass cover each paddock.
What is spring rotational planner/feed wedge
Anthelmintic properties
Drought tolerance
Tap roots
3-4 year persistency
