The Basics of Swine Barn Maintenance
Publish Date: September 1, 2020
The transition in the swine industry to confinement production, where extensive mechanical systems are used automate many routine processes, has created new management needs and challenges. These mechanical systems wear and are prone to failures; therefore, they must be maintained to keep the facility functioning correctly. The cost of the repairs and maintenance can vary widely based on the maintenance program followed and the original equipment installed. Iowa State Extension estimates that the cost of repairs and maintenance annually is 1.5% of the barns original cost, although the type of maintenance program is unknown (Christensen, 2019). To minimize the cost and maximize the barn’s efficiency and lifespan, a maintenance programs must be created and implemented. The different electromechanical systems in a barn (ventilation, feed, water, etc.) all have components that could lead to system failure, thereby having a negative impact on production and pig welfare. For example it has been noted that a feed outage lasting 24 hours can cost at least $1.00 per head in finishing situation (Hollis, 2006). This could be caused by an equipment failure in the feed system and the costs would likely increase rapidly if compounded with multiple equipment failures.

The Environment in Swine Housing
Publish Date: November 1, 2019
Economies of scale and the greater need for efficiency have resulted in the vast majority of pigs being raised indoors. These artificial environments have a great impact on production performance and the health status of both the pig and the worker. With the pork industry becoming more integrated, uniform-style barns are built in multiples, and an error in design can be multiplied many times over. This situation highlights the continued need for adhering to basic design principles in ventilation and environmental control.

Basic Management Practices to Mitigate and Control Odors from Swine Operations
Publish Date: April 9, 2010
Pork producers that have facilities with odor problems or want to be proactive in management approaches to prevent odors have a variety of options. Some of these options are easily implemented, while others are more of a challenge. The cost and benefit of any approach should be carefully considered before implementation.

Biofilters for Odor Control at Swine Facilities
Publish Date: June 3, 2006
Biofiltration can reduce odor and hydrogen sulfide emissions from livestock facilities by as much as 95% and ammonia by 65% (Nicolai & Janni, 2000) This method of odor control has been shown to be both economical and effective in swine raising systems. Biofilters are most easily adapted to mechanically ventilated buildings or on the pit fans of naturally ventilated buildings. Biofilters can also treat air vented from under manure storage covers.
