Introduction – elevated broiler house


Elevated Slatted Floor means raised on plastic flooring which commonly used in broiler houses.

100% plastic slatted floor

The height of shed is raised by 6ft -7ft from the ground level using either concrete pillars or steel column to allow

accumulation manure below the slats area.

The distance between two pillars are 10ft (3m)

This system saves on litter, reduces contact between birds and manure, and allows manure removal without

disturbing the hens.

Lower ventilation cost due to reduced tunnel speed as the slatted floor is cooler compared to deep litter house.

Introduction


Eliminates the need to use litter such as sawdust and wood chips on the floor.

Go green - Save environmental resource

The manure droppings are much drier and concentrated between flock

The floor is drier and cooler

Low moisture level significantly reduces ammonia gas and nitrogen production, thus

reducing bacterial growth and minimize risk of infection of intestinal parasites and disease

Improved FCR with better growth weight between 10-15% Vs conventional deep litter house

and broiler cage.

Benefits of Elevated Slatted Floor System


No chance of litter born disease

Easy collection of dropping

Hygiene

Lower mortalities, faster growth, quicker to the market, better carcass quality

and drastically improved paw quality.

keep the flocks healthier that require less medication use, which improves the

live cost of production.

Benefits of Elevated Slatted Floor System


We are different from other poultry house builders.

Against the continually rising energy costs (propane gas and electricity),

we build energy efficient housing to save operating cost.

We build ENERGY EFFICIENT POULTRY SYSTEM

We save energy cost by providing:-

Insulated building

Vapor barrier

Airtight finishing

Attic ventilation / Natural ventilation

Ceiling inlets

Solar Reflectance Roofing

Structure – Codes of pratices

INTRODUCTION

The intention of this Part is to ensure that the structure of an agricultural Class 2 building is safe. The

safety of a structure depends on several factors and the following criteria are relevant in design

consideration:-

• Code of practice

• Design Loading

• Safety Factors

• Structural Analysis

• Properties of Materials

DESIGN INFORMATION AND CRITERIA

Codes Of Practice

BS 5950 Structural Use of Steelwork in Building

• BS5950 Part 1 : 2000 – Code of practice for design in simple and continuous

construction

• BS5950 Part 5 : 1998 – Code of practice for design of cold formed sections

Loads

BS6399 : Part 1 : 1996 – for dead load

BS5502 : Part 22 : 1993 – for loading of any building for agriculture

CP3 : Chapter V : Part 2 : 1972 – for wind load


Structure – Design Loading

Load factor and combinations of the following loads are complying to the Table 14 for BS 5502 : Part 22 :

1993 : Section 16

a. Maximum Permissible Wind Load

Wind loads acting on each roof level will be computed from a basic 3 second gust wind speed.

b. Maximum Permissible Vertical Superimposed Dead Load

c. Maximum Permissible Vertical Superimposed Live Load

Superimposed Dead Load kN/m2

Roof 0.15

Ceiling & Services 0.20

Building insulation value reading

Ceiling recorded uniformity of temperature. Cooler buildings increase liveability

End Wall Cooling Pad and Fan Design Theory

Design Theory

- End wall and side wall cooling pad minimum distance can’t below 5ft, if too near

will cause the turbulence between the cool pad and reduce the air flow.

- End wall and side wall fan minimum distance can’t below 5ft, to avoid the

fan scrambling the air and reduce the air flow.


Insulation Door

These insulation doors are all

aluminium constructed with .050

aluminium extruded frame, inner and

outer, injected with a two-pound

density polyurethane foam core and

cover use the same material with

incubator. Door frame use 2 layer of

rubber sealant to prevent air leak.


Insulation Door

Air leaking will cause the static pressure drop and affect internal temperature.
