Water Requirement for Pig in Abattoir

Recommended water requirement for a pig per day in an abattoir is:

Correct Answer: 450 Litres

As per FAO (1978) recommendations, the water requirement for both clean and unclean operations in an abattoir per animal per day:

Water Requirements in Abattoir (FAO, 1978)

• Cattle/Buffalo: 1000 Litres/day
• Pig: 450 Litres/day
• Sheep/Goat: 100 Litres/day

Why This Data Matters

• Large quantities of water are needed for scalding, cleaning carcasses, sanitation, and effluent management.
• The BOD (Biochemical Oxygen Demand) of abattoir effluent: 1500–2000 mg/litre.
• Primary treatment reduces BOD by 75–80%; biological filters reduce BOD by 95%.

Memory Tip

Cattle = 1000 L, Pig = 450 L, Sheep/Goat = 100 L — each is roughly less by the number of livestock units: Cattle=1 unit, Pig=0.5 unit (450≈half of 1000), Sheep=0.2 unit (100≈1/10th of 1000).
