The future of PKE

By products

• Industry question – Market access / public perception
• Use of more cereals (Barley / Wheat / Maize)
• Brewers Grain
• Adult Deer – Cereals
• Young Deer – Cereals + Brewers Grain / Soy meal (Protein)
• Higher quality forages/forage blends specifically grown as crops to

harvest for silage, baleage or hay

• More winter active forages, dry summer tolerant species

Fodder Beet

• Spring Sown / Winter Feed
• Yield range 16 to 30 tonne of DM
• $1750 to $3400 per ha
• Cultivation, precision planted, at least 3 to 5 spray applications
• No transition required with deer
• Deer do extremely well on beet
• Unlike other animals no need for daily shift can be up to a week
• Timing and management is critical in the growing phase

Lucerne

• Quality high performance Spring Summer Autumn Feed
• Perennial legume 7 to 12 years
• Deep rooted, like free draining soils
• 10 day gut adjustment period
• Sound management plan – optimal performance rotation grazing
• 5 to 6 paddock / break rotation
• A significant platform 1 to 2 paddocks hopeless???
• Ideal dryland plant

Red Clover

• High Quality Spring Summer Autumn feed
• Handles heavy soils than Lucerne
• 3 to 4 year option
• Exceptional liveweight growth rates
• Sound management plan – optimal performance rotation grazing
• 5 to 6 paddock / break rotation
• Ideal option under water

Plantain

• Winter active Herb
• Up to 17 tonne of Dry matter
• Handles a range of soil types and environments
• High levels of calcium, magnesium, sodium, phosphorus, zinc, copper

and cobalt

• Ecotain Plantian – Enviromental benefits
• Captain Plantian – Most winter active cultivar on market

Chicory

• One of the forages most preferred by deer (Hunt and Hay, 1990)
• Perennial tap rooted forage herb
• Up to 20 tonne of drymatter
• Spring, Summer and autumn active
• concentrations of all minerals, except for Ca, are 17 to 48% higher (P<

0.05) in chicory than in plantain
