Pig skin diseases refer to a range of conditions that affect the skin of pigs, which can be caused by various factors such as genetics, environmental factors, and病原体 infection. These diseases can range from relatively mild conditions to severe health issues that can lead to high mortality. In this article, we will discuss some common pig skin diseases and their symptoms.
Greasy Pig Disease (Facial Dermatitis/Exudative Epidermitis)
Greasy Pig Disease, also known as Pig Facial Eruptions and Exudative Eczema, is a skin condition characterized by redness, scales, and exudates on the pig's face, ears, and body. The condition usually affects neonatal piglets, but it can also occur in older pigs. The exudates from the Lesions can have a greasy texture, and if left untreated, the lesions can progress to form thick scabs and crusts.
Symptoms of Greasy Pig Disease
- Redness and scales on the face, ears, and body
- Exudates that give the skin a greasy texture
- Lesions that develop rapidly and can become extremely painful
- Ulcers or open sores on the skin
- Depression in the spirit and脱水 in severe cases
Treatment of Greasy Pig Disease
Treatment for Greasy Pig Disease typically involves antibiotics to fight off the bacterial infection caused by Staphylococcus hyicus. Affected pigs should be hydrated using an electrolyte solution. The condition can often be controlled by identifying and managing the underlying causes of the skin lesions, such as excessive fighting in piglets.
Lice
Lice are external parasites that feed on the blood of pigs and can cause significant discomfort and skin irritation. Pigs are most commonly infested with Haematopinus suis, which are typically found in the skin folds around the neck and jowl, the ears, the legs, and the flanks.
Signs of Lice in Pigs
- Yellow-brown Colouration
- Visible with the naked eye, especially in white pigs
- Rubbing and scratching of the skin
- Hair loss and irritation
Treatment of Lice
Infected pigs should receive immediate treatment with an injectable.Avermectin. For pigs closer to slaughter, it may be necessary to consider meat withdrawal. All animals in the herd should be treated immediately to prevent further spread.
Mange
Mange is a skin parasitic disease caused by either Sarcoptes scabiei var. sui or Demodex phylloides mites. Sarcoptic mange is present in almost all countries where pig farming is practiced and is considered the most important ectoparasite of pigs (Desrosiers, 2011). Mange causes skin lesions, discomfort, and can reduce both growth rates and feed efficiency.
Signs of Mange in Pigs
- Ear shaking and rubbing of the skin against the pen sides
- Sensitivity and irritation of the skin
- Thickened, crusted skin with secondarily infected due to scratches
- All.age groups may be affected
Treatment of Mange
Mange should be treated immediately, without delay, using an avermectin. Ideal treatment regimens involve at least two separate treatments 14 days apart to manage any newly hatched adult mites that may emerge after the first treatment.
Ringworm
Ringworm is a common fungal disease in pigs that causes crusting lesions around the base of the ear, head, and flanks. The disease is usually caused by the Dermatophyte fungus Trichophyton verrucosum.
Symptoms of Ringworm in Pigs
-Circular, red, or yellow-white crusting lesions around the ears
- Lesions that can spread and eventually coalesce
- A self-limiting disease that can resolve over time
Treatment of Ringworm
Ringworm can be self-limiting, but severe infestation can be treated with disinfectants such as 1% savlon or hexetadene. In some cases, enilconazole may be prescribed by your vet under the Veterinary Medicines Directive (VMD) cascade, but it is important to consider a 28-day meat withholding period. Your vet can provide further guidance on this treatment.
Swine Pox
Swine pox is an acute, highly contagious viral disease that causes red, raised circular lesions on the pig's abdomen, flank, face, and pinna. The virus is carried by the pig as an asymptomatic carrier
Symptoms of Swine Pox
- Lesions appear in the early stage as small circular or ovoid Vesicles containing straw-colored fluid
- Lesions enlarge over time and crust forming
- Pigs tend to self-heal within three weeks
Treatment of Swine Pox
There is currently no specific treatment for swine pox, its impact is limited, and it mainly affects younger piglets.
##.Ticks
Ticks can become a significant problem in the US
Signs of TICK Infestations in Pigs
- Redness, swelling, or inflammation at the site of the tick bite
- Engorged ticks may fall off and remain in the area
- Ticks may be found in clusters
Treatment of Ticks
Small-scale infestations can be手动_removed and pigs removed from the contaminated habitat. Currently, there are no topically or parenteral treatments licensed for use in the UK.
Table of Contents, pig skin diseases are diverse and can have significant impacts on pig health and performance. Pig farmers should recognize these conditions and implement appropriate control measures to prevent and mitigate their effects.
