ABSTRACT
Pigs are often perceived as dirty animals, hygiene and cleanliness are considered the cornerstones of herd health management on every pig farm rearing large numbers of animals in a building. Hygiene refers to science of the establishment and maintenance of health in both humans and animals. Hygiene–or more accurately the lack of it–is cited as one of most important factors in disease transmission. The hygiene level and kind of sanitation measures that have to be applied differ according to the disease's features. Pig diseases can be classified into different categories. Good reproductive performance depends on the good health of the urinary and reproductive tracts of breeding animals. Urogenital disease may be responsible for production and economic losses and may in turn impact herd profitability. Lameness is a major health problem in sows reared indoors under confined conditions, resulting in painful movement. Keeping large pig populations healthy is a daily challenge for every farmer to ensure high technical and economic performance.
