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
Diagnosis

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

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

What requirements?
Adapted to today to be ready for tomorrow!
• Sizing• Biosecurity
• Ergonomics• Eco-responsibility
Lille - 22 to 24 February 2017Livestock housing: let's build the future 17
Batch management?Leaving age and weight per stage?Size of halls?
Cost of design?Manpower, automation, materials needed? Housing maintenance and ageing?
Typology of the livestock farmer?Prospects of expansion?Quality approach?
Milestone 1: To establish the project specifications
Lille - 22 to 24 February 2017Livestock housing: let's build the future 18
Get the big picture of the farm.
To respect external biosecurityMilestone 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

Biosecurity, easy if planned!

Sizing of air inlets Milestone 2: to avoid design pitfalls
Insufficient ExcessiveCompetition between hallsHeat in summerUnder 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 winterAir speed at pig level-Degradation of the Index-Risk of respiratory problems-Risk of emergence of streptococcal-Risk of digestive problems-Carcass fatness-Abnormal behaviour

Position of air inlets Milestone 2: to avoid design pitfalls
Suitable UnsuitableAdjustable Provided with flangesMultiple
Unprotected and subject to windsNear risk areasPositive pressure

Sizing and position of air inlets Milestone 2: to avoid design pitfalls
• Severe cases of streptococcal in post-weaning
Lille - 22 to 24 February 2017Livestock housing: let's build the future 24
• Air inlet too small and subject to winds− Only one gable open− Aspiration in the building − Cold
