Development of Low Cost
Methods to Farm
Swiftlets
Definition & Issues
“Swiftlet farming” can be defined as a production system of edible bird’s nests
using specifically-designed buildings for the swiftlets to roost and nest. Just like bees, the swiftlets are free to roam and forage
anywhere outside, only returning to roost at night.

Farming in Specifically-Designed
Buildings, The Ingenieur, April 2007, pp.

Issues
• Lucrative industry which attracts non-sustainable practices with those trying to maximise returns
• High failure rates of 70-80%• One of the fastest growing indusries in S.E. Asia• No accepted code of practice• Lack of opportunity for “low income groups” to
benefit from the industry• Lack of research into breeding biology of the
swift, low cost farming methods, etc• A number of “unknowledgeable” advisors and
consultants in the industry.
Objectives
• To understand swiftlet nesting behaviour under captivity more thoroughly
• To develop low cost methods of swiftlet farming
• To research and develop sustainable practices and promote a code of practice
• To disseminate this information to rural communities
• To look at potential breeding practices

Conventional Thinking Based on Observation
Swiftlets are at home nesting on many different materials in “unrecommended”
conditions
The classic style (unofficial industry standard)
Our Hypothesis
Appears Swiftlets like to nest near people
Do not have to be massive buildings
Not necessary to construct using materials and methods most
“consultants” are recommending

Land DevelopmentMaterial Cost
• Clay• Sand
• CementLabour Cost
Risk Management
• Proper survey of area before building
• Construct proper conditions for nesting
• Use correct acoustics (part of project will be to record bird sounds for distribution)
• Sustainable harvesting
• Prevent predators entering
Power Supply
The next stage would be to build swiftlet houses from pre-cast ferro-cement sheets which
could be assembled on site.
This building method could support 2 story construction
