Principles of Air Filtration for Swine Facilities

Publish Date: November 15, 2022

Air filtration is a commonly used biosecurity practice to minimize the spread of airborne diseases. Common airborne diseases include Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Mycoplasma hyopneumoniae, and influenza A virus in swine (IAV-S). These diseases present substantial productivity and economic losses for producers. For example, PRRSV is estimated to cost the US swine industry $664 million per year (Holtkamp et al., 2013). Air filtration systems require careful consideration to determine if they are needed and beneficial. This fact sheet will cover these key topics related to selecting a filtration system and managing the system.

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.

Why, How, and What to Keep? Environmental Records

Publish Date:

Unless you are an accountant, record keeping is probably not your idea of fun. And, unlike your operation’s production records, you may not consider environmental records to be a necessity for your facility’s livelihood. However, kept properly, environmental records are beneficial to your facility, and in many cases, they are a requirement. As discussed here, environmental record keeping refers to items related to manure and nutrient management at and around the production facility. Environmental record keeping is a necessity for regulator-required nutrient and manure management plans (NMP or MMP) or for USDA’s Comprehensive Nutrient Management Plans (CNMP). In this fact sheet we will discuss how keeping environmental records can benefit your facility, what records should be kept, and how you can incorporate the records into the overall management of your facility.

Infiltration: The Hidden Enemy

Publish Date: January 1, 2023

Proper ventilation performance, especially during cold-weather periods, is affected by many factors including the performance of the planned primary inlet system and the hidden, unplanned leakage inlets from cracks and construction gaps (i.e., infiltration). This article will describe research conducted at Iowa State University to determine the extent and influence of infiltration on ventilation performance and some on-farm practices to help reduce the unwanted consequences from excessive infiltration.

Disposal of Mortalities from Swine Production Sites

Publish Date: October 15, 2020

There is no best way to dispose of swine mortality carcasses. While some methods may work well for managing routine mortalities, the ability to scale them up to handle large numbers can be difficult. These methods may not adapt to times when catastrophic mortalities occur. The optimum system for any particular farm location is based on a number of criteria, including the current state of the protein/oil market, the biosecurity required, the distance to processing sites, the local public's perception, the government regulations that apply to that location, the environmental conditions, and the ability of the farm to carry out the different procedures. The death losses at a farm can be classified broadly as one of two types, routine or catastrophic. Routine mortalities represent a small proportion of herd and occur throughout the course of normal production. Catastrophic mortality events involve high death losses within a distinct period of time. These methods can also be used for catastrophic loses but the larger scale in a shorter time frame often increases process intensity. Additionally if losses are due to disease, they have a higher biosecurity risk.
