It is the place where animals are being slaughters or we can say that slaughter house of the animals. Livestock processing industries comprising commercial operations that:
(1) Slaughter animals including poultry with all processing capacity of animals
(2) Manufacture products derived from the slaughter of animals including:
(a) Tanneries, fellmongeries; or
(b) Rendering or fat extraction plants with an intended production capacity
The main and the major activities involved in the operation of an abattoir are:
- receiving and holding of livestock
- slaughter and carcass dressing of animals
- chilling of carcass product
- carcass boning and packaging
- freezing of finished carcass and cartoned product
- rendering processes
- drying of skins
- treatment of wastewater
- transport of processed material
A vast/mass animal disposal area must be identified in case there is an outbreak of exotic disease. This area should be away from watercourses and groundwater. The soil should be suitably friable for digging but also as impermeable as possible.
Because of hygienic reasons abattoirs use large amounts of water in animal processing operations. This produces large amounts of wastewater that must be treated.
Two treatments are given as first effective primary treatment before secondary treatment will increase the overall effectiveness and efficiency of wastewater treatment systems, as it is cheaper to remove physically the fat and solids than to treat later in secondary and tertiary treatment facilities.
Skin protection or preservation by dry salting is a common process at small abattoirs that are remote from tanning operations and often export their hides and skins for tanning. After salting, often in converted cement truck mixers, the hides are hung to dry for a minimum of 5 days. During this period, the salt draws the moisture out of the hide, together with the protein-filled fluids contained in the attached flesh. |
