Bovine Ulcerative Mammary Dermatitis (BUMD) is a relatively rare but serious skin condition affecting the mammary glands of dairy cows. This disease is characterized by the development of ulcers and inflammation in the mammary tissue, leading to discomfort, reduced milk production, and potential secondary infections. Early detection and management are crucial to prevent severe complications and ensure the health and productivity of the affected cows. (Source)
How It Is Spread
Bovine Ulcerative Mammary Dermatitis is not a contagious disease; rather, it is typically associated with environmental factors, poor hygiene, and underlying health issues. The condition can arise when the mammary skin is exposed to irritants or becomes compromised due to trauma, leading to ulceration and infection.
Transmission
BUMD is not transmitted from cow to cow. Instead, it develops in individual cows due to factors such as:
- Poor Sanitation: Dirty and damp bedding can harbor bacteria and other pathogens that contribute to the development of ulcers on the mammary glands.
- Injuries: Physical trauma to the mammary tissue, such as scratches or cuts, can create entry points for bacteria, leading to infection and ulceration.
- Compromised Immune System: Cows with weakened immune systems are more susceptible to developing skin conditions, including BUMD.
- Inadequate Nutrition: Nutritional deficiencies can weaken the skin’s integrity, making it more vulnerable to damage and infection. (Source)
Symptoms
The symptoms of Bovine Ulcerative Mammary Dermatitis can vary in severity but often include the following:
- Ulceration: Open sores or ulcers on the mammary skin, often with a raw or necrotic appearance.
- Redness and Swelling: Inflammation around the affected areas, causes the skin to appear red and swollen.
- Discharge: Pus or other exudates may be present in severe cases, indicating a secondary bacterial infection.
- Pain and Discomfort: The cow may exhibit signs of pain, such as reluctance to be milked or restlessness.
- Reduced Milk Production: Due to discomfort and potential mastitis, milk yield may decrease. (Source)
How It Is Caused
Bovine Ulcerative Mammary Dermatitis is caused by a combination of factors, including:
- Environmental Conditions: Unsanitary living conditions, particularly wet and dirty bedding, can lead to prolonged exposure of the mammary glands to irritants and pathogens.
- Trauma: Physical injuries to the mammary tissue can initiate the formation of ulcers, which can become infected if not properly treated.
- Bacterial Infections: Secondary bacterial infections, often involving common environmental bacteria such as Staphylococcus and Streptococcus species, can exacerbate the condition.
- Immunosuppression: Cows with compromised immune systems due to stress, illness, or poor nutrition are more prone to developing BUMD. (Source)
Who Is Vulnerable
All dairy cows are potentially vulnerable to Bovine Ulcerative Mammary Dermatitis, but certain factors increase the risk:
- Older Cows: Aging cows may have thinner, more fragile skin that is more susceptible to injury and infection.
- High-Milk-Producing Cows: Cows that produce large quantities of milk may experience more stress on their mammary glands, making them more vulnerable to skin conditions.
- Cows in Poor Environmental Conditions: Cows kept in unsanitary or overcrowded conditions are at a higher risk of developing BUMD.
- Cows with Poor Health: Animals with pre-existing health issues or weakened immune systems are more likely to develop this condition. (Source)
Problems It Can Cause
If left untreated, Bovine Ulcerative Mammary Dermatitis can lead to several serious problems:
- Secondary Infections: Open ulcers can become infected with bacteria, leading to severe infections that may spread beyond the mammary gland.
- Mastitis: BUMD can predispose cows to mastitis, a painful inflammation of the mammary gland that further reduces milk production.
- Chronic Pain: The condition can cause significant discomfort, leading to chronic pain and affecting the cow’s overall well-being.
- Economic Losses: Reduced milk production, veterinary treatment costs, and potential culling of severely affected cows can result in substantial economic losses for dairy farmers. (Source)
Treatment
Treating Bovine Ulcerative Mammary Dermatitis involves addressing both the ulcers themselves and any underlying causes:
- Wound Care: Regular cleaning of the affected area with antiseptic solutions is essential to prevent infection and promote healing.
- Antibiotics: In cases where secondary bacterial infections are present, a veterinarian may prescribe antibiotics to control the infection.
- Topical Treatments: Application of medicated ointments or creams can help soothe the skin, reduce inflammation, and promote healing.
- Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) may be used to alleviate pain and reduce inflammation.
- Improving Environmental Conditions: Ensuring clean, dry bedding and maintaining good hygiene practices are critical to preventing recurrence. (Source)
Vaccines
Currently, there is no specific vaccine available for Bovine Ulcerative Mammary Dermatitis. However, maintaining overall herd health through regular vaccinations against common bovine diseases can help reduce the risk of secondary infections and improve the cows’ immune response.
Prevention
Preventing Bovine Ulcerative Mammary Dermatitis involves several key management practices:
- Maintaining Cleanliness: Regularly clean and change bedding to keep the environment dry and free from contaminants.
- Proper Nutrition: Ensure cows receive a balanced diet with adequate vitamins and minerals to support skin health and immune function.
- Monitoring and Early Intervention: Regularly inspect the mammary glands for early signs of ulceration or injury, and address any issues promptly.
- Minimizing Trauma: Take care to avoid injuries to the mammary glands during milking or handling, and ensure that milking equipment is well-maintained. (Source)
Home Remedies
While professional veterinary care is essential for treating Bovine Ulcerative Mammary Dermatitis, some home remedies can help support the healing process:
- Aloe Vera Gel: Applying aloe vera gel to the affected area can soothe the skin and promote healing due to its anti-inflammatory and moisturizing properties.
- Calendula Cream: Calendula cream has natural antiseptic and healing properties that can aid in the recovery of minor skin injuries.
- Honey: Raw honey has antibacterial properties and can be applied to ulcers to help prevent infection and promote healing. (Source)
How Humans Can Protect Their Dairy Cows
Farmers can protect their dairy cows from Bovine Ulcerative Mammary Dermatitis by:
- Ensuring Good Hygiene: Keep the cow’s environment clean and dry to minimize the risk of skin infections.
- Regular Monitoring: Inspect cows regularly for signs of skin injuries or ulcers, particularly during high-risk periods such as calving or peak lactation.
- Prompt Treatment: Seek veterinary advice at the first sign of ulceration to prevent complications and promote quick recovery.
- Education and Training: Educate farm workers on the importance of early detection and proper management of BUMD. (Source)
Cure
While there is no single “cure” for Bovine Ulcerative Mammary Dermatitis, the condition can be effectively managed with prompt treatment, good wound care, and by addressing the underlying causes. Preventative measures, such as maintaining cleanliness and minimizing trauma, are key to avoiding the development of the disease in the first place.

Global Organizations and Expert Opinions
Global organizations like the World Organisation for Animal Health (OIE) and the Food and Agriculture Organization (FAO) emphasize the importance of good animal husbandry practices in preventing skin conditions like Bovine Ulcerative Mammary Dermatitis. Veterinary experts from institutions such as the American Veterinary Medical Association (AVMA) and the European Food Safety Authority (EFSA) advocate for improved hygiene, regular monitoring, and early intervention to protect dairy cows from such conditions.
Conclusion
Bovine Ulcerative Mammary Dermatitis is a serious condition that can impact the health and productivity of dairy cows. By understanding the causes, symptoms, and treatment options, dairy farmers can take proactive steps to prevent and manage this disease. Ensuring good hygiene, providing proper nutrition, and seeking prompt veterinary care are essential for maintaining the well-being of the herd. With the right management practices, the risk of BUMD can be minimized, ensuring healthier and more productive dairy cows.
