• Our strengths:
– Observing pigs and the anticipating health problems
– Solid experience in the ventilation of livestock housing
Creation of charts for the ‘intermediate’ stages and
‘non-developed’ stages

Presentation of the farm and context
• 130 farrowing-fattening sows, 480 places for post-weaning and 880
fattening places
• Context
– Summer and end of 2015: cough and mortality at the end of fattening associated with
seizures
• Finding: Actinobacillus pleuropneumoniae and PRRS
• Expertise:
– Health measures taken
– Bacterial problem fostered by an atmosphere error
• Analysis of UNIPORC data on slaughter
• Ventilation control

13. Diagnosis

• Monolithic brick building
• 4 rooms with different air intakes
• Air intakes: inadequate sizing and
distribution
• Faulty fans room 2
• 40 respiratory seizures + total
seizures from March to Nov 2015

14. Recommendations and results

VENTILATION CONTROL = PREVENTION
Reflections on the livestock housing
of the future
• Open the outdoor/indoor air
intakes
• Size and improve air intakes in
the room
• Change a fan
• Use sliding windows

Get the big picture of the farm.
To respect external biosecurity
Milestone 1: To establish the project specifications
• External biosecurity right
from the first plans!
– Location of the housing on the site
• Proximity of risk elements
– Prevailing winds
– Movements of animals and people

Sizing of air inlets Milestone 2: to avoid design pitfalls
Insufficient Excessive
Competition between halls
Heat in summer
Under ventilation
-Decrease in consumption
-Risk of respiratory problems
-Risk of emergence of streptococcal
-Risk of digestive problems
-Hoof lesions and lameness
-Risk of choking
Difficulty of maintaining temperatures
in winter
Air speed at pig level
-Degradation of the Index
