How do I review a hog farm’s barn ventilation and manure storage?

Ventilation protects the animals and the building. Ask what system is installed, how old the fans, inlets and controllers are, and what alarms exist. Ask what happens if power fails, and whether a backup generator has actually been tested. Walk the barn on a warm day and a cold one if you can, and notice air quality, humidity and noise.

Manure storage deserves equal attention. Look at the walls, liners and pumps, ask how much capacity remains at the busiest time, and ask what has gone wrong. Find out how the manure is used or moved, who does it, and what equipment that needs. Ask the seller about the neighbours, and talk to them if the seller agrees, since complaints about smell or traffic can affect how the farm operates.

Ask also what the farm’s animal care routines look like, and whether they follow recognized farm animal care practices. Have an independent person review the building, and ask your lawyer to confirm there are no unresolved disputes or orders on the property. Ask a neutral advisor to watch the barn at its busiest, because ventilation problems are most visible when the animals are full-grown and the weather is extreme.

Key takeaways

• Ask for ventilation service records and proof the backup power has been tested.
• Examine manure storage walls, liners, pumps and remaining capacity at peak.
• Ask about complaints, disputes or past problems with neighbours.
• Visit during extreme weather if possible, when systems are under the most strain.
