Newcastle Disease: Prevention Starts Before the Outbreak

Newcastle Disease: Prevention Starts Before the Outbreak

Newcastle disease (ND) is one of the most contagious viral diseases affecting poultry, causing severe economic losses due to increased mortality, poor growth, reduced egg production, and decreased flock performance.

 How Does It Spread?

The virus spreads rapidly through:

• Respiratory secretions and feces.
• Contaminated feed, water, equipment, and clothing.
• Direct contact with infected birds.
• Wild birds and live bird markets.

⚠️ Key Clinical Signs

• Respiratory distress (gasping, coughing, sneezing).
• Green watery diarrhea.
• Depression and reduced feed intake.
• Nervous signs such as twisted neck, tremors, paralysis, and circling.
• Sharp decline in egg production and poor shell quality.
• High mortality in virulent outbreaks.

Why Is Newcastle Disease Dangerous?

The disease can result in:

• Significant mortality.
• Reduced weight gain and feed efficiency.
• Poor flock uniformity.
• Severe losses in egg production.
• Increased susceptibility to secondary bacterial infections.

🛡️ Protect Your Flock

✔ Implement a strategic vaccination program.

✔ Maintain strict biosecurity and regular disinfection.

✔ Minimize stress through proper ventilation, nutrition, and management.

✔ Monitor flock health and investigate any unusual respiratory or nervous signs promptly.

 

 KORVAC ND (LaSota): Your First Line of Defense

KORVAC ND (LaSota) is a live attenuated Newcastle disease vaccine containing the LaSota strain, developed to stimulate a strong immune response and provide reliable protection against Newcastle disease in healthy chickens. Live LaSota vaccines are widely used because they induce robust local respiratory and systemic immunity and are commonly administered by eye drop, spray, or drinking water, depending on the vaccination program.

 Why Choose KORVAC ND (LaSota)?

• Rapid induction of protective immunity.
• Strong local and systemic immune response.
• Suitable for routine vaccination and booster programs.
• Helps reduce the impact of Newcastle disease and improve flock performance when used as part of a comprehensive vaccination and biosecurity program.

Medical Tip

A healthy flock begins with prevention. Combining KORVAC ND (LaSota) with proper biosecurity and good farm management is the most effective strategy to protect poultry from Newcastle disease and reduce production losses.
