Ecoshelters®
- History & development:
To
the current date approx 1189 Ecoshelters® have been
manufactured for the Australasian farm sector. They
house mostly pigs, calves, sheep, etc. in fact most
livestock can utilize an Ecoshelter®.
The
concept began back in 1992 when Redpath Ideal were approached
to design a building for the pig industry. After about
two years of trials & development the project was
made public and the Ecoshelter® was released to
the farming sector.
Such
was the success that research was under taken by the
Dept. of Agriculture based in Western Australia, at
their research unit at Medina. Some data supplied in
the following information is sourced from that research
work.
An
Ecoshelter® is a steel framed building designed
for low cost entry into the animal industry ( mainly
pigs). They are a quick build solution to expanding
existing piggeries & intensive stock farming. Organic
matter is usually added to each Ecoshelter® to use
as a bedding base.
Ecoshelters®
have been designed to provide maximum opportunity for
ventilation. In each end above the eave line a screen
vent is located to allow air flow 24 hours per day therefore
minimizing condensation and humidity. Both ends and
both sides have roll up/ down blinds to control air
flow. Optional fixed or adjustable awnings are available
if required.
Continuous
air movement is important as it helps equalize carbon
dioxide and humidity levels within the Ecoshelter®.
With improved environmental conditions healthier pigs/
animals can be grown compared with sheds associated
with high humidity. Although the optimum air flow has
never been established it is suggested that a minimum
air flow of 12m/m be considered, below this level air
flow is unpredictable.
An
Ecoshelter® with blinds should easily achieve this
air flow even on a calm day. To achieve this air flow
blinds are important.
Ecoshelters®
are available in the following span widths. Spans
may be gutter connected to create multi-bay width units.
Lengths of structiures is at (3m increments) (9'11").

Many

the individual site location.
Also
available is the Redpath Ecoark® - A re-locatable
8m (26'3") x 6m (19'10") animal cover structure.

info continued…………
Pigs
are generally housed in the Ecoshelter® at 3 – 4
weeks of age until sold at about 95 - 125 kg (281 lb).
Indicators from pig producers indicate this is about
3 weeks faster than normal.
As
the effluent is absorbed in the straw there is no need
for containment ponds/ dams.
Pigs
are housed in more environmentally friendly conditions
with animal welfare concerns are minimized.
Cleaning
out of the bedding is only at the end of each growing
cycle and may have a re sale re use value.
Stocking
rate is typically at 1 pig per square metre (square
yard) of Ecoshelter® (based on grower finisher).
It
is now common for pig producers purchasing an Ecoshelter®
to lay a concrete floor with bedding or pens. An Ecoshelter®
is extremely cost effective in comparison to conventional
buildings.
A
9.1m (29'10") x 45m (147') Ecoshelter® can be constructed
in as little as 5 days, pending weather site & design.
