Electrical wiring for swine buildings
Publish Date: June 3, 2006
Proper design and installation of swine facility electrical systems are crucial to using electricity efficiently, providing safety for workers and animals, and minimizing potential fire loss. A majority of all farm fire losses are related to electrical system failure (Figure 1). Many wiring practices that are acceptable for use in our homes are unsafe when used in livestock housing because of exposure to dust, moisture, corrosive gases, and physical damage. Inferior wiring causes hazardous conditions for livestock and humans, expense of early rewiring of many buildings, and possible fires. Even when fires do not occur, poor wiring may contribute to higher maintenance costs. The mere fact that a system works doesnt speak for its safety. Special wiring methods and components are needed for swine structures.

Recirculation Systems for Manure Removal
Publish Date: June 3, 2006
Recirculation systems involve the addition of varying amounts of dilution water in order to improve the removal of manure from the animal area. The two types of recirculation systems used in pork production facilities are underslat flushing and pit recharge systems. Both systems use a shallow gutter that is flushed or drained periodically to remove waste from the building to the lagoon or storage basin. Open gutter systems have been used in the past but are no longer recommended because of concerns with disease transmission.

Managing Market Pigs in Hoop Structures
Publish Date: June 3, 2006
Pork producers in the United States who are looking for lower cost structures for raising pigs have shown a great deal of interest in hoop structures or hooped shelters as facilities for housing market or finishing pigs. Producers need to be aware of the advantages and disadvantages of this type of housing. A number of manufacturers offer these units for sale, but little objective data are available to help producers decide if a hoop structure is a good investment. The information in this publication is intended to help producers and designers resolve some of the issues involved in using a hoop structure. The fact sheet discusses some of the management techniques that hoop structures require, and it presents economic factors that can be used to analyze the alternatives.

Shallow Gutter Manure Collection Systems
Publish Date: June 3, 2006
Research has shown and field experience has verified that corrosive and odorous gas production increases with storage time and storage temperature. Manure can be removed from a swine barn by: (1) manual or mechanical scraping, (2) gravity draining, (3) flushing with dump tanks, siphons or pumping systems with automatic or manually controlled valves, or (4)…
