Lille - 22 to 24 February 2017Livestock housing: let's build the future 2

Summary

1. Porc.Spective: Expertise in pig veterinary medicine

2. Impact of livestock housing on the health and well-being ofpigs

3. Effects on health related to a ventilation problem

4. Reflections for efficient livestock housing of the future

5. Porc.Spective’s involvement in new projects

Porc.Spective: the firm



Porc.Spective: the firm

Porc.Spective: 18 years of expertise in veterinary medicine– Advanced Veterinary Studies Certificate (CEAV)– European College of Porcine Health Management (ECPHM)

Within Chêne Vert Conseil (Veterinary group)

• Specialized in organized animalindustries

• 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

Impact of livestock housing on the health and well-being

of pigs


Clinical observations related to the housing


The parameters to be taken into account

• Age• Flooring / type of

housing• Air speed• Type of air inlet• Heating

Perceivedtemperature

• Humidity• Gas and dust

concentrations• Air renewal

Air quality

• Isolation• Air-tightness

Flooring, wallsand pretanks

Effects on health related to a ventilation problem

Illustration by a clinical case: actinobacillose during fattening



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

VentilationSlaughter data analysis


• 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

Recommendations and results

Ventilation Slaughter data analysis


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

Reflections for efficient livestock housing of the

future



What requirements?

Adapted to today to be ready for tomorrow!

• Sizing• Biosecurity

• Ergonomics• Eco-responsibility


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


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!

To respect internal biosecurityMilestone 1: To establish the project specifications

Wash basin at each station, boot washer


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

Allows even air distribution in the roof space

Allows cold air to mix with hot airEasily adjustable or automaticallyEASY MAINTENANCE

Does not allow using the corridor as cold zoneNear obstaclesAir speed at pig levelHealth problems and abnormal behaviour

Sizing and position of air inlets Milestone 2: to avoid design pitfalls

• Severe cases of streptococcal in post-weaning


• Air inlet too small and subject to winds− Only one gable open− Aspiration in the building − Cold

10 to 15% loss/batch

Construction: 2015


Sizing of extraction Milestone 2: to avoid design pitfalls

• Zootechnical and health consequences:– Change in feeding behaviour– Digestive and respiratory diseases– Decreased yield

Insufficient Excessive Fans and turbines

Centralized ventilation hatches

Heat in summer Difficulty of maintaining temperatures in winterAir speed at pig levelDifficulty setting at minimum flow

Design of extraction Milestone 2: to avoid design pitfalls


• Easy to maintain• Automatic sliding windows• Centralized ventilation: hatch size


Heating sizing and location Milestone 2: to avoid design pitfalls

• Energy recovery?• Power?• Adjustment?• Positioning in the hall

– Disruption of air circuits– Insufficient heat input

Upkeep!


Consequences of design errors on well-being Milestone 2: to avoid design pitfalls

Hoof and leg injuries

Thermal discomfort…

Overcrowding Cannibalism

Through design it is won!Milestone 2: avoid the pitfalls of design
