DETAILED VACCINATION SCHEDULE FOR CHICKENS – THE SECRET TO A HEALTHY, HIGH-PRODUCTIVE FLOCK - GREENFEED - GIẢI PHÁP CHĂN NUÔI

To ensure healthy chicken growth, reduce disease risk, and achieve optimal productivity, adhering to a chicken vaccination schedule is paramount in poultry farming. At each stage of development, from chicks to laying hens, immune requirements differ, necessitating a suitable vaccination program.

This article will help farmers understand the chicken vaccination schedule for each stage, along with vaccination techniques and important considerations to increase disease prevention effectiveness.

1. Vaccination schedule for chickens according to development stages

The vaccination schedule for chickens is developed based on their physiological characteristics and the risk of common diseases at each stage. Vaccinating at the right time will help chickens develop active immunity and minimize the risk of disease outbreaks.

Vaccination Schedule for Broiler Chickens

Timing	Disease Prevention Vaccine	Administration Route
1–3 days old	Coccidiosis vaccine (applies only to floor-raised poultry)	Oral
5–7 days old	Newcastle disease vaccine (Lasota strain)Infectious Bronchitis (IB) vaccine	Eye/nasal drops
10–12 days old	Gumboro disease vaccine	Eye/nasal/oral administration
14–18 days old	Newcastle + IB booster (1st booster)	Eye/nasal drops
14–18 days old	Fowl Pox vaccine	Wing-web puncture
14–18 days old	Gumboro booster (1st booster)	Oral
21–28 days old	Newcastle disease vaccine (highly virulent Genotype VII strain)	Intramuscular injection
25 days old	ILT (Infectious Laryngotracheitis) vaccine	Subcutaneous injection
42–45 days old	Avian Influenza vaccine	Intramuscular injection

Vaccination schedule for laying hens

Timing	Disease Prevention Vaccine	Administration Route
1 day old	Marek’s disease vaccine	Subcutaneous injection (back of the neck)
1–3 days old	Coccidiosis vaccine (applies only to floor-raised poultry)	Oral
5–7 days old	Newcastle disease vaccine (Lasota strain)Infectious Bronchitis (IB) vaccine	Eye/nasal drops
10–12 days old	Gumboro disease vaccine	Eye/nasal/oral administration
14–18 days old	Newcastle + IB booster (1st booster)	Eye/nasal drops
14–18 days old	Fowl Pox vaccine	Wing-web puncture
14–18 days old	Gumboro booster (1st booster)	Oral
21–28 days old	Newcastle disease vaccine (highly virulent Genotype VII strain)	Intramuscular injection
25 days old	ILT (Infectious Laryngotracheitis) vaccine	Subcutaneous injection
42–45 days old	Avian Influenza vaccine	Intramuscular injection
140 days old	Booster vaccination for Newcastle disease, IB, and Gumboro disease	Subcutaneous injection
150 days old	Booster vaccination for ILT and Avian Influenza	Subcutaneous injection

2. Secrets to using vaccines for chickens effectively

Vaccines are only maximally effective when used correctly. Important notes:

Maintain proper temperature: always keep the vaccine at 2-8°C, avoid direct sunlight, and do not freeze.
Dilute the vaccine with clean water: use boiled and cooled water, free of chlorine or disinfectants.
Inject at the correct site:
- Chicks: eye, nose, or subcutaneous injection in the neck.
- Adult chickens: intramuscular or under the wing.
Inject at the correct time: it should be done early in the morning or late in the afternoon to minimize stress.
These factors directly affect the ability of the flock to develop immunity.

3. Common mistakes when vaccinating chickens

In practice, many errors in the vaccination process can reduce the effectiveness of the vaccine, including:

Injecting in the wrong site or dosage, causing swelling at the injection site and reduced appetite.
Diluting the vaccine too early or leaving it for too long before use.
Not adhering to the booster schedule, leading to interrupted immunity.
Not sanitizing injection equipment, leading to secondary infections.
Avoiding these mistakes will help the vaccination program achieve optimal effectiveness.

Conclusion

Adhering to the chicken vaccination schedule is the most proactive and effective disease prevention solution in poultry farming today. A scientifically-designed vaccination program not only reduces treatment costs but also enhances productivity and long-term profitability.

With proper vaccination schedules, techniques, and good care, farmers can build healthy flocks with high resistance and stable growth.

Proactive and timely vaccination is a crucial step in maintaining a healthy flock and improving farming efficiency. If you need advice on a suitable vaccination plan for your specific model, the Greenfeed team of experts is always ready to support you in optimizing productivity sustainably.

FAQ

1. Is it mandatory to strictly follow the vaccination schedule for chickens?

It doesn't need to be absolutely precise to the day, but it's recommended to vaccinate within the recommended timeframe to ensure the chickens develop immunity at the right stage. Vaccinating too late or too early can reduce the effectiveness of disease prevention.

2. Should chickens with mild illnesses be vaccinated?

No. Only vaccinate healthy chickens in stable condition. Vaccinating sick chickens will reduce the chances of developing immunity and may cause shock to the flock.

3. Why is booster vaccination necessary for chickens?

Booster vaccinations help maintain stable antibody levels in the chickens' bodies. If booster shots are skipped, immunity will gradually decrease, and the flock will be more susceptible to disease.

4. Is it possible to combine multiple vaccines in a single injection?

It depends on the type of vaccine. Some vaccines can be combined, but you need to follow the manufacturer's instructions or consult your veterinarian to avoid interactions that may reduce effectiveness.

5. How should chickens be cared for after vaccination?

It is recommended to supplement with vitamins and electrolytes and maintain a well-ventilated environment for 1-2 days after vaccination to reduce stress and help the chickens recover quickly.

6. How to create a vaccination schedule suitable for each farm?

In addition to the basic schedule, farmers should base their decisions on the local epidemiological situation, farming model, and expert advice. You can also seek technical support from organizations like Greenfeed to develop a more optimal treatment plan.
