- Improved soluble carbohydrate levels
- Lowest aftermath heading cultivar available in
mid-season heading class.
- Very high dry matter production
- Novel endophyte - has shown resistance to Black
Beetle, Argentine Stem Weevil and Pasture Mealy Bug
New technology perennial ryegrass with AR6 novel
endophyte for no risk of staggers.
EXTREME™ is a medium-broad leaved, densely tillered perennial
ryegrass. EXTREME™ has been bred for high dry matter
production, cool season activity and has very low aftermath
heading. EXTREME™ is a non-staggering ryegrass that does not
contain Lolitrem B.
EXTREME™ has shown improved resistance to Black Beetle
damage over cultivars containing AR1. This insect protection
occurs because EXTREME™ contains Ergovaline, with
concentrations being highest in the crown of the plant (where
insect damage occurs) and lowest in the leaves, minimising
intake of Ergovaline by grazing animals. The ‘Grazing
Management’ section below recommends practices to minimise
stock intake of Ergovaline.
In preliminary trials EXTREME™ has shown improved levels of
water soluble carbohydrates. Higher water soluble carbohydrates
in combination with reduced aftermath heading can improve
rumen efficiency, and therefore animal performance.
GRAZING MANAGEMENT
Extreme contains a novel endophyte (AR6), which produces
Ergovaline (which has shown resistance to Black Beetle
damage). Ergovaline levels are highest in the crown of the
plant during the summer and autumn.
Ingestion of Ergovaline can affect animal performance and
health. To minimise any adverse effects, avoid prolonged set
stocking, or grazing fresh regrowth, of such pastures during
summer and autumn.
Set stocking can occur during winter and spring, but for best
pasture production, persistence, quality and best animal
condition and performance, research indicates that farmers
should practice rotational grazing. If in doubt, always seek
professional advice.
What the producers say...
Beau Gooch, Devonport TAS
Two years ago Beau sowed about 60 ha to Extreme perennial ryegrass as
part of a mix. “The Extreme has done really, really well”. “It’s been a bit of a shock just
how much feed we have run into,” Beau said. “Because of all the rain, we’ve had about 90 per cent of the stock on
these ryegrass paddocks just to keep on top of the feed. It’s been
absolutely incredible just watching it grow.”
“We were able to lamb down all the ewes on two paddocks of Extreme
which supported the ewes and lambs through to weaning,” Beau said.
Beau is planning to replace more of the property’s old pastures with new
perennial ryegrasses, in particular Extreme, which has proven its worth in
terms of quality and quantity and favoured by the Gooches because of its
persistence.
Dave Ingpen
“When you look at the amount of feed from these new ryegrasses and
what we get from the other grasses, there is just no comparison,” Dave
said. “And considering the amount of growth in those paddocks, I probably
could have done two cuts,” Dave said. The large square bale silage will
be fed to the ewes in autumn to act as a feed wedge. “What I like about these ryegrasses is that they can be sown in autumn
and you achieve full utilisation by spring. And they respond so well to
urea.”
“The feed growth is phenomenal. You give it a hit of urea, lock it up and
it just takes off.”
Michael, Kim and Wayne Blake, Busselton WA
“The move from annual to perennial has produced results beyond our
expectations,” he said. “The Extreme is performing better than any
annual we've seen. Apart from having to spray for red-legged earth mite,
which is pretty normal for this area, the only problem with it is that we
literally have too much feed. “The cows milk really well off it too.”
“We plan to install another pivot system in a year or two, and we’re going
to continue using Extreme under irrigation as we expand our herd and
production.”
