Lumpy Skin Disease in Cattle

Lumpy Skin Disease (LSD) is becoming a growing threat to cattle worldwide, especially in tropical regions like Southeast Asia. If you’re a farmer, veterinarian, or livestock trader, early recognition and prevention of LSD is crucial to minimize financial loss and safeguard your herd’s health.

What is Lumpy Skin Disease?

Lumpy Skin Disease (LSD) is a viral infection affecting cattle and buffalo, caused by the Capripoxvirus. It leads to the formation of skin nodules, fever, reduced milk production, and significant economic impact.

Symptoms of LSD

• High fever (up to 41°C)
• Firm skin nodules on neck, limbs, udder, and genitalia
• Swollen lymph nodes
• Decreased milk yield and appetite
• Eye and nasal discharge
• Abortion in pregnant cows

How it Spreads

LSD is mainly spread by biting insects such as mosquitoes, flies, and ticks. It can also spread through direct contact with infected animals, contaminated tools or facilities, and infected milk or semen.

Treatment and Prevention

No specific antiviral treatment is available. Supportive care includes anti-inflammatory drugs, antibiotics for secondary infections, and proper nutrition and hydration.

Prevention includes:

• Vaccination with live attenuated vaccines
• Vector control (insecticides, repellents)
• Isolation of infected animals
• Strict biosecurity protocols

Economic Impact of LSD

LSD can cause severe economic damage due to:

• Decreased milk production
• Weight loss and poor meat quality
• Damaged hides and skins
• Costs for treatment and vaccination
• Trade and transportation restrictions
