Hard concrete floors with a wooden float finish are ideal. Depending on resources the floors can be fully slated or partially slated. Fully slated floors are hygienic but can be expensive to install. The floors should be easy to clean because clean floors help to prevent the build-up of disease causing pathogens and parasites. Too smooth floors should be avoided, as they are slippery especially when they are wet. Rough surfaces cause injuries to the pig’s legs and udder.
