The document outlines the layout design and essential components of a modern abattoir, detailing its engineering aspects, site selection criteria, and operational considerations for effective animal slaughter and waste management. It emphasizes the importance of social acceptance, specialized facilities, and adherence to hygiene standards. Additionally, it provides specifications for the physical design, including minimum space requirements and height regulations for different areas within the slaughterhouse.

2. ABATTOIR
Slaughter house – technically referred as Abattoir.
Traditionally called- butcheries, giving negative feeling
due to foul smell, unhygienically disposal of wastes.
meant for human
SH- place where animals consumptions are sacrificed.
Public acceptance - concern

3. TYPES OF ABATTOIR
Modern abattoir
Semi-modern-Facilities for slaughter and bleeding on the floor but subsequently entire
dressing, washing, halving and quartering takes place on the rails in hoist position
Traditional abattoir

4. CONSIDERATIONS
Policy decisions-
Site, size, trade practices and range of byproducts
Engineering aspects- layout plan
Cost consideration
Infrastructure depends upon the-
• Maximum daily kill
• A regular full time operation
• Disposal & treatment of waste
• Byproducts utilization

5. SELECTION OF SITE
Outskirt of the town or city
Elevated ground for easy draining
Adequate and potable water
Concrete road facilities for transportation
Uninterrupted electric supply
Space for future expansion
Away from airport
Social and religious acceptance
Free from pollution, odour, chemical plants etc

6. CONTD--
Availability of skilled manpower
Availability of meat animals
Soil quality- to support good foundations and pillars of the buildings
Separate entity i.e. reasonable distance from other buildings
Separation of clean and dirty area

7. SIZE
Depends on the number of animals of each species to be
slaughtered everyday
Range of operation (slaughter/ dressing/ deboning/ packaging)
Availability of fund
Byproduct processing

8. Civil Infrastructure
Lairage
AM examination
Humane slaughter
Flaying, dressing and washing of the carcasses
Hanging carcasses and edible offals
Byproducts handling
Inspection of meat and disposal of condemned carcasses or part there of
Staff welfare

10. DESIGNINGSTANDARDSANDGUIDELINES
A minimum site area of 1800 square meters will be required to accommodate all modules.
The abattoir layout presented is based on a rectangular site 30 meters by 60 meters.
The required minimum height for processing is 3m.
The slaughter area for large animals, which include wench, should be 4.5m.
The windows should be high enough to prevent children from looking in and walls should be tiled
to height > 2m.
