A standard poultry vaccination schedule in India starts with Marek’s Disease vaccine on day 1 (usually at the hatchery), followed by Ranikhet/Newcastle Disease (Lasota) between days 4-10, Gumboro (IBD) between days 14-21, and booster doses through the following weeks. Broilers follow a condensed 3-4 week schedule due to their short lifespan, while layers follow an extended schedule through 17+ weeks that also includes Fowl Pox and Infectious Bronchitis vaccination. Exact timing can vary slightly by hatchery, region, and disease pressure, so schedules should always be confirmed with a veterinarian.
Introduction
Vaccination is the single most important disease-prevention tool in commercial poultry farming. A missed or delayed vaccine dose can expose an entire flock to diseases like Newcastle Disease or Gumboro, both of which spread fast and can cause significant mortality and financial loss.
This guide lays out the standard poultry vaccination schedule in India for broilers and layers, based on established veterinary and government animal husbandry references, along with practical guidance on storage, administration, and common mistakes to avoid.
Why Poultry Vaccination Matters: The Scale of the Industry
India’s poultry sector isn’t a small operation — it’s one of the largest in the world, which is exactly why disease control at scale matters so much:
- India ranks among the top 3 egg producers globally, with annual egg production exceeding 149 billion eggs (2024-25, DAHD/BAHS data).
- India produces approximately 4.5-5 million tonnes of broiler meat annually.
- The Indian poultry market was valued at approximately USD 32.9 billion in 2025.
- Commercial poultry accounts for roughly 84% of total egg production in the country, meaning the vast majority of India’s egg supply depends on organised, vaccination-protected flocks.
At this scale, a single disease outbreak in an unvaccinated or improperly vaccinated flock doesn’t just affect one farmer — it can disrupt local supply chains and prices. This is why a consistent, correctly-timed vaccination schedule is non-negotiable for commercial poultry operations.
Poultry Vaccination Schedule for Broilers
Broilers are typically raised for only 5-8 weeks before reaching market weight, so their vaccination schedule is short and focused on the highest-impact diseases.
| Age | Vaccine | Disease Protected Against | Route |
|---|---|---|---|
| Day 1 | Marek’s Disease | Marek’s Disease (fowl paralysis) | Subcutaneous (usually at hatchery) |
| Day 3-5 | Lasota (RD/Newcastle, F strain) | Ranikhet/Newcastle Disease | Intraocular / Intranasal |
| Day 7-9 | IBD (Gumboro) | Infectious Bursal Disease | Intraocular / Drinking water |
| Day 16-18 | IBD Booster | Infectious Bursal Disease | Drinking water |
| Day 24-26 | Lasota Booster | Ranikhet/Newcastle Disease | Drinking water |
Poultry Vaccination Schedule for Layers
Layers are kept for a much longer production cycle, so their schedule extends further and includes additional vaccines not typically needed for broilers — Fowl Pox and Infectious Bronchitis.
| Age | Vaccine | Disease Protected Against | Route |
|---|---|---|---|
| Day 1 | Marek’s Disease | Marek’s Disease | Intranasal / Intraocular (at hatchery) |
| Day 5-7 | Lasota (RD, F strain) | Ranikhet/Newcastle Disease | Intraocular |
| Day 14-16 | IBD | Infectious Bursal Disease | Intraocular / Drinking water |
| Day 24-26 | IBD Booster | Infectious Bursal Disease | Drinking water |
| Day 30 | Lasota Booster | Ranikhet/Newcastle Disease | Drinking water |
| Week 5-6 | RD Booster | Ranikhet/Newcastle Disease | Drinking water |
| Week 7 | Fowl Pox | Fowl Pox | Wing-web / Scratching, 0.2 ml |
| Week 8-9 | R2B Strain | Ranikhet/Newcastle Disease | Subcutaneous/Intramuscular, 0.5 ml |
| Week 9 | Deworming | Internal parasites | Oral |
| Week 14-16 | Infectious Bronchitis Booster | Infectious Bronchitis | Drinking water |
| Week 16-17 | Fowl Pox Booster | Fowl Pox | Scratching/Intramuscular |
Broiler vs Layer Vaccination: Key Differences
| Factor | Broilers | Layers |
|---|---|---|
| Total lifespan | 5-8 weeks | 18+ months (production cycle) |
| Vaccination schedule length | ~4 weeks | 17+ weeks |
| Number of core vaccines | 3-4 | 6-8 |
| Fowl Pox vaccination | Not typically required | Required (week 7 and booster) |
| Infectious Bronchitis | Not typically required | Required |
| Deworming included | No | Yes, around week 9 |
Vaccine Storage and Handling — Why It Matters as Much as Timing
A correctly-timed vaccine that has been mishandled is often as ineffective as no vaccine at all. Key practices:
- Store vaccines at 2°C to 8°C from the point of manufacture through to farm use — never freeze liquid vaccines.
- Use insulated cool boxes with ice packs when transporting vaccines to the poultry shed; avoid direct sunlight exposure.
- For drinking-water vaccines, use chlorine-free water — chlorine and disinfectant residues can inactivate the vaccine. Adding skim milk powder to the water is a common practice to help protect vaccine viability.
- Always check the expiry date before use, and never use a vaccine beyond its stated shelf life.
- Dispose of any leftover reconstituted vaccine — it should not be stored for later use once mixed.
Common Mistakes in Poultry Vaccination
- Delaying the first dose — even a few days’ delay in early vaccination (Marek’s, Lasota) can leave chicks vulnerable during their most susceptible period.
- Using chlorinated water for oral vaccines — this is one of the most common, and most avoidable, causes of vaccine failure.
- Skipping booster doses — a single dose without the scheduled booster often provides incomplete or short-lived immunity.
- Inconsistent administration route — switching routes (e.g., intraocular vs drinking water) without following manufacturer guidance can affect how evenly the flock is protected.
- Not adjusting for regional disease pressure — some regions have higher prevalence of specific diseases, and local veterinary guidance may recommend additional or earlier vaccination for those risks.
Why Schedules Can Vary Slightly
The schedule above reflects widely-used Indian government and veterinary references, but it’s worth understanding that hatcheries, state animal husbandry departments, and individual veterinarians sometimes adjust exact day-ranges based on:
- Breed and hatchery-specific protocols
- Regional disease prevalence
- Flock health history
- Vaccine manufacturer recommendations
This is exactly why the schedule should be treated as a reliable framework, not a rigid one-size-fits-all rulebook — always confirm specifics with your veterinarian or hatchery before finalising a farm’s vaccination calendar.
FAQs
Q1. What is the poultry vaccination schedule in India for broilers?
Broilers typically receive Marek’s Disease vaccine on day 1, Lasota (Newcastle Disease) around day 3-5, Gumboro (IBD) around day 7-9 with a booster at day 16-18, and a Lasota booster around day 24-26 — a condensed schedule matching their short 5-8 week lifespan.
Q2. What is the poultry vaccination chart for layers in India?
Layers follow an extended schedule from day 1 through week 17, covering Marek’s Disease, Newcastle Disease (with boosters), Gumboro, Fowl Pox, Infectious Bronchitis, and an R2B strain Newcastle booster, along with deworming around week 9.
Q3. Which poultry vaccine is given first in India?
Marek’s Disease vaccine is typically given first, usually on day 1 at the hatchery before chicks are transported to the farm, since Marek’s Disease is highly contagious and most dangerous to very young chicks.
Q4. Can poultry vaccination schedules vary by region in India?
Yes. While the core schedule is broadly consistent nationally, exact timing can be adjusted by hatcheries, state animal husbandry departments, or veterinarians based on regional disease prevalence and flock-specific health history.
Q5. Why do layers need more vaccines than broilers?
Layers are kept for 18+ months of egg production, giving diseases like Fowl Pox and Infectious Bronchitis more time to affect the flock. Broilers are typically processed within 5-8 weeks, so their vaccination program focuses only on the highest-risk early-life diseases.
Q6. What happens if a poultry vaccine dose is missed?
A missed dose leaves the flock without adequate immunity against that specific disease during a vulnerable window, increasing outbreak risk. If a dose is missed, consult a veterinarian promptly to determine whether it can still be administered or if additional precautions are needed.
