What is African swine fever (ASF), and what should send you to a veterinarian at once?

It is a viral infection with high lethality and a transboundary animal disease. It presents with high fever, haemorrhagic skin patches and acute death. The treatment direction is that no widely available effective vaccine exists in most regions at present 【Verification note: no fixed figure should be given for this item — vaccine development and regional approval status change rapidly and vary by region, so the latest announcement of the local competent authority must be followed】, with culling-based disease control as the main measure. This row belongs to the group that the source chapter treats as needing prompt handling; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or doses are given here.

What is classical swine fever, and what should send you to a veterinarian at once?

It is a viral infection. It presents with fever, diarrhoea and neurological signs. The treatment direction is that a vaccine is available in some regions, subject to local policy. This row belongs to the group that the source chapter treats as needing prompt handling; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or doses are given here.

What is foot-and-mouth disease (FMD), and what should send you to a veterinarian at once?

It is a viral infection that can cross-infect cattle, sheep, pigs and other cloven-hoofed animals. It presents with vesicles on the mouth, snout and hooves, lameness and salivation. The treatment direction is that it is handled according to local policy and is a major transboundary animal disease. This row belongs to the group that the source chapter treats as needing prompt handling; the actual judgement still rests with a veterinarian assessing the individual case, and no drug names or doses are given here.

One table gathers ten common diseases of pigs (*Sus scrofa domesticus*): African swine fever (ASF), classical swine fever, foot-and-mouth disease (FMD), porcine reproductive and respiratory syndrome (PRRS), erysipelas (*Erysipelothrix rhusiopathiae*), swine influenza, internal and external parasites (mange mites, roundworms and others), obesity-related disease in pet pigs, gastric ulcer and *Streptococcus suis* infection. Each row sets out cause, signs, examination, treatment direction and prevention, with the treatment direction given only as a category and never as a dose. It suits the moment when you take on a new group of animals, or when something looks wrong and you want to narrow down the direction first.

Pigs｜10 Common Diseases (cause → signs → examination → treatment direction → prevention)

This content is compiled from the disease table for pigs (*Sus scrofa domesticus*) in the farm animals and horses chapter of the veterinary animal encyclopedia. The same sign calls for different handling in different species, and copying what is done for another species can be harmful — first confirm which animal you are dealing with.

#	Disease	Cause	Signs	Examination	Treatment direction	Prevention
1	African swine fever (ASF)	Viral infection with high lethality; a transboundary animal disease	High fever, haemorrhagic skin patches, acute death	Virological testing; a notifiable disease	No widely available effective vaccine in most regions at present 【Verification note: no fixed figure should be given for this item — vaccine development and regional approval status change rapidly and vary by region, so the latest announcement of the local competent authority must be followed】, with culling-based disease control as the main measure	Strict biosecurity, immediate notification of suspected cases, no feeding of untreated food waste
2	Classical swine fever	Viral infection	Fever, diarrhoea, neurological signs	Virological testing; a notifiable disease	A vaccine is available in some regions (subject to local policy) 【Verification note: no fixed figure should be given for this item — vaccine availability varies with the policy of the local competent authority, so the local announcement must be followed】	Vaccination, biosecurity
3	Foot-and-mouth disease (FMD)	Viral infection that can cross-infect cattle, sheep, pigs and other cloven-hoofed animals	Vesicles on the mouth, snout and hooves; lameness; salivation	Virological testing; a notifiable disease	Handled according to local policy; a major transboundary animal disease	Strict biosecurity, statutory notification
4	Porcine reproductive and respiratory syndrome (PRRS)	Viral infection	Reproductive failure (abortion), respiratory signs	Virological testing	Supportive care; vaccine availability depends on the region 【Verification note: no fixed figure should be given for this item — follow the local competent authority and veterinary instructions】	Biosecurity, vaccination
5	Erysipelas (Erysipelothrix rhusiopathiae)	Bacterial infection	Diamond-shaped skin lesions, arthritis, acute septicaemia	Bacterial culture	Antibiotics require a veterinary prescription	Vaccination (region-dependent), environmental hygiene
6	Swine influenza	Viral infection carrying zoonotic and reassortment risk	Fever, coughing, reduced appetite	Virological testing	Supportive care	Biosecurity; avoid close contact when handling sick pigs
7	Internal and external parasites (mange mites, roundworms and others)	Inadequate environmental hygiene	Itching, thickened skin, wasting	Skin scraping microscopy, faecal examination	Medication requires veterinary guidance	Environmental hygiene management
8	Obesity-related disease in pet pigs	Overfeeding (see the treatment column)	Increased joint load, reduced activity	Body condition scoring	Dietary adjustment requires veterinary guidance	Control feed volume and treats
9	Gastric ulcer	Associated with stress and excessive stocking density	Reduced appetite, dullness	Requires veterinary assessment	Medication requires a prescription; environmental management is the key measure	Reduce stressors, appropriate stocking density
10	Streptococcus suis infection	Bacterial infection carrying a marked zoonotic risk in some regions	Neurological signs, arthritis, septicaemia	Bacterial culture	Antibiotics require a prescription	Environmental hygiene, avoiding contact through wounds

The ten rows above are copied cell by cell from the encyclopedia chapter, neither rewritten nor condensed; the treatment direction is always given as a category only, never as a drug name or dose, and medication requires a veterinary prescription. The line number and content hash of each row in the source chapter are given in the evidence chain at the end.

Limits of this content

This content comes from the farm animals and horses chapter of the veterinary encyclopedia (see the evidence chain for the original location and content hash). The sources at the end are the authoritative materials cited by that chapter; the correspondence is at chapter level, which does not mean every sentence is traced sentence by sentence back to a given source. This material is for education and cannot replace diagnosis and prescription by a practising veterinarian; in an emergency, seek veterinary care immediately. This text has not been clinically reviewed by a named veterinarian.
