Common Goat Skin Diseases and Their Treatments
Like any animal, goats can suffer from a variety of skin diseases and conditions. Some are caused by bacteria or fungi, while others are due to parasites, wounds, or even allergies. Thankfully, most goat skin diseases can be effectively treated if caught early.
Fungal Infections
Fungal infections are common in goats, especially during warm, wet weather. Ringworm and dermatophytosis are two of the most widespread fungal skin diseases in goats.
Ringworm
Ringworm is not actually caused by worms, but is the general name for a contagious fungal infection of the skin. It often first appears as small patches of hair loss that eventually develop into larger lesions with scaly skin and red rings around the edges.
To treat ringworm in goats, antifungal medications can be applied topically or given orally if the infection is widespread. Keeping goats' living areas clean and dry is also key to preventing fungal growth. In severe cases, infected animals may need to be isolated from the herd until the ringworm clears.
Dermatophytosis
Similar to ringworm, dermatophytosis is a general term for skin infections caused by fungi of the dermatophyte family. Lesions often begin small and round, eventually growing into patches of rough, thick, hairless skin that can cover large areas of the body.
Topical antifungal ointments containing miconazole or thiabendazole can be used to treat mild cases. More serious widespread infections may require injectable antifungal medications prescribed by a veterinarian. Keeping goats clean and dry is also important for prevention and control.
Bacterial Infections
Several types of bacterial skin infections are seen in goats, with abscesses and dermatitis being some of the most common.
Abscesses
Abscesses develop when bacteria invade a wound or damaged skin and multiply, causing a pocket of pus under the skin. Common visible symptoms include hot, swollen areas on the skin that are painful and eventually rupture to release the trapped pus.
Treatment involves cleaning and draining the abscess, flushing it with an antiseptic solution, and sometimes placing a drain. Antibiotics may also be prescribed to clear the systemic infection. Prompt treatment of any wounds can help prevent abscesses from developing in the first place.
Dermatitis
Dermatitis refers to skin inflammation and can have many underlying causes. When due to a bacterial infection, common symptoms are redness, itching, crusting scabs, hair loss, and oozing sores.
Bacterial culture and sensitivity testing can identify the specific organism causing infection. Antibiotics are then selected accordingly to treat both skin lesions and any underlying systemic infection. Keeping goats' skin clean and dry is also key to preventing secondary bacterial overgrowth.
Parasitic Infections
Goats frequently suffer from skin conditions related to parasites such as lice, mites, and ticks burrowing into their skin.
Lice
Goat lice feed on skin and cause intense itching, rubbing, scratching, and hair loss. Close examination often reveals groups of small lice gathered at the base of hairs. Topical insecticides like permethrin can kill lice, and may need to be reapplied regularly until all life stages are eliminated.
Mange Mites
Mites burrow into the skin and cause crusty scabs, severe itching, and hair loss, mainly concentrated on the body instead of the extremities. Skin scrapings viewed under a microscope can identify mites. Injectable or pour-on parasiticides like ivermectin provide systemic treatment to kill mites.
Ticks
Ticks pierce goat skin with their mouths to suck blood, injecting toxins that often cause swelling, tenderness, and irritation around the bite. Manual tick removal followed by disinfecting the site can treat mild infestations. For heavy tick loads, commercial pesticides or parasiticides may be required.
Other Skin Conditions
Goats can suffer other types of skin wounds, growths, and allergic reactions unrelated to infections as well.
Injuries and Wounds
Scrapes, bites, cuts, and puncture wounds are common skin injuries in goats that require first aid treatment. Careful wound cleaning, disinfecting, bandaging, and monitoring for signs of infection are important. Antibiotics may be needed if infection develops.
Abscesses and Hematomas
Hematomas occur when blood pools under the skin, usually from blunt trauma. Firm, fluid-filled swellings develop that may eventually harden and slowly shrink over time. Hot compresses can encourage faster absorption of hematomas.
Abscesses not arising from overt skin wounds can also develop from underlying infections and need draining by a veterinarian.
Skin Cancer
Squamous cell carcinoma is the most common skin cancer in goats, appearing as irregular masses that fail to heal. Surgical removal is the standard treatment. Sunscreen and shade can help protect light colored goats that are at increased risk.
Allergic Dermatitis
Just like humans, goats can develop skin allergies to things like plants, chemicals, metals, and more that trigger intense itchiness. Antihistamines and corticosteroid creams relieve mild allergic reactions, while severe cases may warrant allergy testing and immunotherapy injections.
By recognizing common goat skin conditions early, goat owners have the best chance of treating them quickly and effectively for the health and welfare of their herd.
FAQs
What are the most common fungal skin infections in goats?
The most widespread fungal skin diseases affecting goats are ringworm and dermatophytosis. Both cause hair loss and scaly skin lesions that require anti-fungal medications to treat.
How can I prevent bacterial skin infections in my herd?
Keeping your goats' living environment clean, dry, and well-ventilated is key to preventing bacterial overgrowth that can lead to skin infections. Promptly treating any wounds can also reduce abscess development.
What parasites commonly infest goat skin?
Lice, mange mites, and ticks often burrow into goats' skin, causing intense itchiness, irritation, and hair loss. Topical or systemic parasiticides are used to kill the parasites.
What first aid should be provided for goat skin injuries?
Carefully clean and disinfect any skin wounds, then bandage them to keep clean until healed. Monitor for signs of infection like pus, heat, or redness, which would require antibiotic treatment.
How can I protect my light colored goats from skin cancer?
White or light colored goats are at increased risk of developing squamous cell carcinoma. Providing shade and applying goat-safe sunscreen can help prevent skin damage from sun exposure.
