Correct and regular washing and disinfecting improve hygiene, reduce the disease pressure especially for younger pigs, reduce the need for medication e.g. due to intestinal problems and reduce the amount of liver rejections. Taking the time to wash and disinfect prevents the microbes spreading of from one batch to another.
Remove all extra items and solid dirt by shoveling before washing. It is recommended to empty slurry pits a couple of days before washing. This reduces the content of manure fumes in the air. The use of appropriate protective gear (rain clothes, rain boots, breathing and hearing protectors) improves occupational safety, especially when disinfecting.
Soaking the piggery overnight before washing makes washing faster and easier. The easiest soaking method is to use the section's spraying system. A garden sprinkler equipped with a timer is also a good and economical tool. It should be placed on top of the pen fences in the corridor of the piggery and regularly moved to another location. A suitable sprinkling time, amount of water and drop size will be found through trial and error.
We recommend using a hot pressure washer for the actual washing. Dirt that includes protein is best removed at the temperature of +60°C, as hotter water stains proteins onto the surface. Reasonable pressure should be used when washing. Too hard pressure breaks porous concrete surfaces, making them difficult to clean. Cleaning disinfectants can be used as detergents. First, most dirt is washed from the floor and the pen's walls onto the slats. After this, the ceiling and walls as well as the pen's walls and floor are washed again.
The piggery needs to be almost dry (no surface water) before disinfecting because disinfectants are not as effective on surfaces saturated with water. Floor and section heating systems as well as additional heating (electric fans) can speed up drying time. Disinfecting can be carried out for example with a foam lance. It is possible to use disinfectants in some pressure washers. We recommend disinfecting at least the pen floor and walls as well as feeding troughs which is everything below 1.5 meter. Check the dozing of the product according the instructions. Always use a breathing protector during disinfecting!
The piggery should dry out well after washing and disinfecting because bacteria cannot survive on clean and dry surfaces. Heat speeds up drying and at the same time, the section's temperature is increased for the arrival of transfer pigs
