Abstract
Hygienic issues are important in environmental surfaces of animal houses because of food quality and animal welfare. The aim of this study was to review methods in cleanability research of cattle barns and piggeries. Surface materials, animal welfare and hygiene are also discussed. Concerning different detection methods of cleanness, visual methods have dominated in field studies, but some successful attempts to use optical methods are also presented. A wider selection of different kinds of instrumental, microbiological and visual methods and their combinations have been used in laboratory studies. Radiochemical methods have been demonstrated to be suitable as quantitative laboratory methods. In the case of material studies, laboratory experiments are important prior to field experiments in order to screen potential materials, whereas the field studies provide practical information about the behaviour of the surface materials. The importance of cleanness of environmental surfaces in cattle barns and piggeries is also discussed in the context of material development.
Highlights
Hygienic issues are important in environmental surfaces of animal houses because of food quality, animal welfare and even safety of the personnel
The cleanness of surfaces in cattle barns and piggeries is affected by many factors e.g. size, lay-out and surface materials of pens and other sections (Aarnink and Wagemans 1997, de Belie et al 2000b, Barker et al 2007)
A few of the studies presented in the tables focus purely on cleanability issues, but details relating to cleanability were selected from the studies
Summary
Hygienic issues are important in environmental surfaces of animal houses because of food quality, animal welfare and even safety of the personnel. Belie et al 2000b, Calleja Carrete 2005, Aarnink and Verstegen 2007). Environmental conditions such as indoor temperature and moisture content as well as cleaning methods and frequency affect cleanness of the surfaces. The main aim of this survey is to review detection methods of cleanability, because farm hygienic measures are important criteria for the safety and quality of both meat
