Goat Skin Problems and Common Dermatological Conditions
Goats can suffer from a variety of skin problems and dermatological conditions. Some are contagious fungal infections like ringworm, while others are caused by parasites, trauma, or immune disorders. Many goat skin diseases produce visible skin lesions, scabs, and hair loss that can be identified through pictures and physical examination.
Common Goat Skin Diseases
Some of the most prevalent skin conditions affecting goats include:
- Lice infestations
- Mange mites
- Ringworm
- Warts
- Abscesses
- Orf virus
- Dermatophilosis
- Photosensitization
Catching and treating skin problems early can prevent discomfort, complications, and spreading to the rest of the herd. Here is more about some common goat skin diseases and how to identify them.
Goat Lice
Goats can become infested with sucking and biting lice. Heavy lice populations lead to chronic itching, rubbing, and biting that causes hair loss, thickened skin, and anemia.
Signs of lice include:
- Itchy goats constantly rubbing against objects
- Rough, patchy haircoat with areas of hair loss
- Red, inflamed skin lesions from rubbing and bites
- Anemic-looking mucous membranes
- Seeing lice eggs and actual lice crawling on the skin
Mange Mites
Mange is caused by mites that infect the skin. The sarcoptic itch mite burrows into the skin causing severe itching, crusting lesions, and hair loss. Demodectic mange and psoroptic mange mites lead to milder symptoms but still produce dermatitis and hair thinning.
Signs of mange infestation are:
- Intense itching and scratching
- Thick crusty skin lesions
- Scabs and calcified nodules
- Balding patches, especially around the eyes, mouth, ears, chest, and legs
- Thickening and wrinkling of the skin
Ringworm
Ringworm is a contagious fungal infection that passes between goats, other livestock, and humans through direct contact. Spores also survive in the environment. It causes circular bald patches with scaly skin.
Identifying ringworm includes:
- Round, coin-sized lesions on the face, ears, legs, or back
- Crusting skin with hair loss in the patch
- Skin folds or thickens at lesion edges
- Can spread in circular pattern across the body
Warts
Goats commonly develop cutaneous papillomas caused by a virus, which manifest as wart-like growths on the skin. They usually appear where there are breaks in the skin like the teats, udder, ears, eyes, or mouth.
Warts on goats look like:
- Small white/grey bumps on hairless skin
- Cauliflower-like mound shaped lesions
- Pinhead sized to over 1 inch in diameter
- Commonly on udders, teats, face
- Can spread rapidly to cover large areas
Abscesses
Abscesses are pockets of pus under the skin often caused by a bacterial infection. Abscesses typically start as swollen, painful areas that eventually rupture, ooze pus, and scab over.
Signs of an abscess include:
- Initial swelling, hot and tender to touch
- Enlarging area becomes firm and cool
- Eventual rapture releasing yellow/white pus
- Draining sore seals over with a scab
Orf Virus
Orf is a viral infection transmitted through breaks in the skin. It causes blister-like sores around the mouth and muzzle. Kids are most susceptible although adult goats can also be infected.
Orf virus signs are:
- Clustered blister-like lesions on lips, gum, tongue
- Pustules rupture leaving raw ulcerated areas
- Crusty scabs around mouth and nose
- Lesions can spread to teats and udder
Dermatophilosis
Dermatophilosis is a highly contagious bacterial infection leading to crusty scabs mainly on the back, neck, and shoulders. It thrives in warm, humid climates.
Identifying dermatophilosis includes:
- Raised, matted scabs lifting away fur
- Scabs increase in size and thickness over time
- Can cover large portions of skin
- Oozing lesions if scabs removed
Photosensitization
Photosensitization is skin damage as a result of increased sun sensitivity from liver damage, kidney disease, or certain plant toxins. Affected areas do not have pigmentation so burn easily.
The condition appears as:
- Swelling, oozing, scabs on white skin
- Crusting dermatitis on the ears, nose, eyelids
- Lesions worsen with sun exposure
Diagnosing Goat Skin Conditions
There are some steps goat owners can take to try diagnosing skin conditions:
- Visually inspect the goat's skin for any abnormalities
- Look closely at the hair for signs of external parasites
- Take the goat's temperature - many diseases cause fever
- Check for enlarged lymph nodes which may indicate infection
- Submit skin scrapings or lesion samples to a vet for microscopy
- Biopsy suspicious growths for lab analysis
- Consult a veterinarian for conclusive diagnosis
A goat with any signs of skin disease should be isolated from the herd until diagnosis and treatment. Contagious conditions like ringworm, warts, and mange can spread rapidly through a herd.
Veterinary Exam
A veterinarian will perform a comprehensive physical exam of the affected goat's skin. This includes:
- Visual inspection of lesions and distribution pattern
- Palpation to check for swelling or sensitivity
- Microscope analysis of skin scrapings
- Fungal culture or bacterial culture
- Biopsy of growths for histopathology
- Blood tests to assess overall health
Based on clinical signs, lab tests, and response to initial treatment, the vet can provide a definitive diagnosis. They will then outline an appropriate treatment plan.
Lab Tests
Lab tests that help accurately identify goat skin conditions include:
- Microscopy - Scrapings examined under a microscope can reveal mites, fungal spores, or bacteria.
- Fungal culture - Isolating a fungus sample in the lab allows specific antifungal selection.
FAQs
What are some common skin problems in goats?
Goats can suffer from lice, mange, ringworm, warts, abscesses, orf virus, dermatophilosis, and photosensitization. Pictures help identify visible skin lesions, hair loss, and other symptoms.
How can I diagnose a skin issue in my goat?
Visually inspect the skin, check for fever, look for external parasites, take skin scrapings for microscopy, biopsy growths, and consult a vet for diagnosis. Isolate suspect goats.
Why is a veterinary exam important for goat skin disease?
A vet performs a full physical, takes samples for lab analysis, prescribes testing, and provides a definitive diagnosis based on response to initial treatment. This guides appropriate care.
How can I prevent skin diseases in my goat herd?
Practice good sanitation, isolate incoming goats, control parasites, avoid overcrowding, monitor for symptoms, treat conditions quickly, and consult a vet to protect herd health.
