Biosecurity is the most cost-effective and efficient method for preventing and controlling diseases. Implementing proper biosecurity measures ensures the health and welfare of your flock.

What is Biosecurity?

Biosecurity means protecting your birds from disease by reducing their exposure to vectors or fomites.

Vectors:

Living organisms like rodents, other birds, insects, and pets that can carry diseases.

Fomites:

Non-living objects like shoes, clothing, car tires, equipment, feed, water, dust, people, and even the air that can transmit diseases.

Vectors and fomites help spread viruses, bacteria, parasites, and other harmful microorganisms, impacting your poultry’s health.

 

Key Biosecurity Measures

1. **Quarantine**: Separate new or sick birds from the flock for at least 4 weeks.

2. **Source Birds Carefully**: Purchase birds from National Poultry Improvement Plan (NPIP) approved sources.

3. **Avoid Wild Birds**: Keep your flock away from wild birds, especially waterfowl.

Flock Management Tips

1. **Reduce Stress**: Maintain fresh feed, clean water, good ventilation, and overall bird comfort.

2. **Limit Exposure**: Control access to your birds, especially from people who have been around other birds.

3. **Sanitize Regularly**: Clean and disinfect equipment, coops, and tools frequently.

Components of a Good Biosecurity Plan

1. **Isolation**: Quarantine new birds and isolate sick ones immediately.

2. **Management**: Reduce stressors and ensure proper flock management practices.

3. **Traffic Control**: Limit and monitor the exposure of your birds to people and animals.

4. **Cleaning & Sanitation**: Regularly clean and disinfect all areas and equipment.

 Flock Management Strategies

– **Manure Management**: Properly store and dispose of manure, considering local laws and environmental concerns.

– **Mortality Disposal**: Follow local, state, and federal regulations for disposing of dead birds to avoid attracting pests.

Maintaining Proper Husbandry

– **Vaccination and Supplements**: Use appropriate vaccinations and supplements.

**Regular Monitoring**: Observe birds regularly for signs of illness.

– **Predator and Pest Control**: Implement measures to control predators, rodents, pests, and parasites.

Traffic Control

– **Visitor Protocols**: Ensure visitors follow biosecurity practices like using footbaths or boot covers.

– **Equipment Disinfection**: Disinfect shared tools and equipment before use.

– **Clothing Precautions**: Wear different clothes and footwear when visiting places with other birds.

Cleaning and Disinfection Steps

1. **Dry Clean**: Remove all litter, manure, and debris.

2. **Soap**: Wash surfaces thoroughly with soap.

3. **Rinse**: Rinse off the soap completely.

4. **Dry**: Allow surfaces to dry completely before disinfecting.

5. **Disinfect**: Use effective disinfectants like Quaternary Ammonia or a 10% bleach solution.

Handling Mortality in Your Flock

– **Identify Causes**: Determine if the mortality rate is normal or indicates a larger issue.

– **External Factors**: Address issues like predators or weather if they are the cause of deaths.

– **Record Keeping**: Keep detailed records of illnesses and deaths to aid in diagnosis.

**Report Issues**: Notify animal health officials if you suspect a serious disease.

Reportable Diseases

Certain diseases must be reported to state authorities, such as Avian Influenza, Fowl Typhoid, and Newcastle Disease. Check with local regulations for a complete list.
