The term "Health" means different things to different people. Absence of diseases is clearly a prerequisite but in pigs it means more than that. It is a state of physical and psychological well-beings that allows the pig to express its genetic potential for maximising productivity, reproductive performance and lean meat production.
The term "disease" means an unhealthy disorder of body and mind, sometimes with pain and unease, that is likely to prevent the pig from exploiting its genetic potential resulting in lowered productivity.
The level of clinical disease is described by the term morbidity. Disease can be clinical (i.e. the affected pig shows clinical signs) or sub-clinical (the affected pig shows no obvious clinical signs). Sub-clinical disease can also have an adverse affect on productivity. You should distinguish between sub-clinical disease and sub-clinical infection,. Every healthy herd, without exception, carries a multitude of potentially pathogenic infections, mainly in the gut but also in the nose, throat, skin and genitals, which are not causing disease either clinical or sub-clinical.
There is a delicate balance between these potential pathogens and the pigs' immunity to them. Any physical or psychological disturbance of this immunity may render the pig susceptible.

康健之謂，人之所見不一也。疾病者不可謂康健，此亦明矣，然康健于彘之所謂，非無疾病可盡之也，實乃言其身心逸豫之態(tài)利其遺傳潛力之表達(dá)，由此而極生產(chǎn)率、繁殖與瘦肉產(chǎn)量之所用。
