Salgen Vaccine – The Smart Way to Control Salmonella/Paratyphoid in Pigeons

Salmonella (also known as Paratyphoid) remains one of the most damaging and persistent diseases affecting racing and breeding pigeons worldwide. Despite modern hygiene, nutrition, and loft management, the disease continues to surface year after year – often when fanciers least expect it.
Veterinary field experience and laboratory data consistently show that over 40% of pigeons are natural carriers of Salmonella, frequently without obvious symptoms. These healthy‑looking birds are the silent source of repeated infections within lofts.
Because Salmonella cannot realistically be removed from the pigeon environment, long‑term control depends on vaccination – not just treatment.
Extreme care should be taken when introducing new birds into your loft, as Salmonella is highly contagious and can have a devastating impact on the health and performance of your birds. It is a naturally occurring disease, and studies show that up to 40% of birds can be carriers without showing obvious symptoms.
How Salmonella Affects Pigeons
Salmonella is a bacterial infection that primarily targets the digestive system but can spread to the liver, joints, reproductive organs, and bloodstream.
It is often triggered by:
Racing stress
Breeding pressure
Transport
Moulting
Overcrowding
Poor immunity
Once active, it spreads rapidly through droppings, contaminated drinkers, feeders, baskets, and direct contact between birds.
Droppings – The First Visible Warning Sign
One of the earliest and most reliable indicators of Salmonella infection is a change in droppings.
Healthy pigeon droppings should be:
Firm
Well‑formed
Brown with a white urate cap
When Salmonella becomes active, droppings often change colour and consistency:
Typical Salmonella Dropping Colours
🟢 Green droppings
Very common
Indicates liver involvement and systemic infection
🟡 Yellow‑green or mustard coloured droppings
Suggests bile disturbance and intestinal inflammation
💧 Watery droppings
Sign of gut infection and dehydration
🟤 Pale brown or foamy droppings
Poor digestion and bacterial imbalance
⚪ Excess white urates
Kidney stress and toxin involvement
These changes are often accompanied by:
Weight loss
Ruffled feathers
Reduced appetite
Wing or joint swelling ("boils")
Poor breeding results
Dead‑in‑shell eggs
Young bird mortality
Decline in racing performance
Importantly, many carrier birds may show no visible signs at all, while still infecting the rest of the loft.
Why Antibiotics Alone Are Not Enough
Antibiotics can be useful during acute outbreaks, but they do not solve the problem long‑term:
They may suppress symptoms temporarily
They do not prevent reinfection
They do not stop carrier birds from spreading bacteria later
Repeated use increases resistance
Many lofts fall into a cycle of:
Outbreak → Antibiotics → Temporary improvement → New outbreak
This cycle only ends with proper vaccination.
What Is Salgen Live Vaccine?
Salgen is a live attenuated (weakened) Salmonella vaccine developed specifically for pigeons.
It contains a real Salmonella strain that has been carefully weakened in the laboratory so that:
It cannot cause disease
It cannot invade organs normally
It cannot multiply aggressively
But it still trains the immune system exactly as a natural infection would
This creates strong and long‑lasting protection in both:
The bloodstream (systemic immunity)
The digestive tract (intestinal immunity – where Salmonella lives)
Key Benefits of Salgen Live Vaccine
Strong, broad immune response
Major reduction in bacterial shedding in droppings
Lower infection pressure in the loft
Protection against clinical disease
Control of silent carrier birds
Improved breeding success
Improved race performance
Long‑lasting protection with booster programs
Is a Live Vaccine Safe?
Yes – when used correctly.
Salgen is produced by:
Selecting a pigeon‑specific Salmonella strain
Weakening it through attenuation
Freeze‑drying it under sterile conditions
Storing and transporting under cold‑chain control
Vaccinated birds may shed tiny amounts of the weakened strain for a few days, but:
It is non‑virulent
It cannot cause outbreaks
It does not create carriers
It is rapidly cleared by the immune system
In commercial poultry farming, similar live Salmonella vaccines have been used for decades, routinely vaccinating flocks of 25,000 chicks or more with outstanding safety and disease-control success.
These large-scale vaccination programs have been in place for many years and have proven hugely successful. Without live vaccination, Salmonella outbreaks in poultry production would be widespread, persistent, and extremely difficult to control.
25,000 chicks or more with outstanding safety and disease‑control success. Without these programs, Salmonella outbreaks would be widespread and economically devastating.
The same science applies to pigeons.
Safe Use Guidelines
To ensure maximum safety and effectiveness:
Vaccinate only healthy birds
Do not vaccinate during antibiotic treatment
Wait at least 10 days after finishing antibiotics
Avoid vaccinating sick, stressed, or very young birds
Maintain normal loft hygiene
The Professional Veterinary View
Senior veterinary and medical advisers with decades of experience in:
Immunology
Microbiology
Virology
Pathology
Poultry and avian medicine
consistently agree that vaccination is the cornerstone of Salmonella control.
Treatment manages outbreaks.
Vaccination prevents the next one.
Final Thoughts
If you regularly see:
Green droppings
Yellow or watery droppings
Poor condition
Joint problems
Breeding failures
Or unexplained performance drops
Salmonella should be high on your list of suspects.
Testing confirms the problem.
Treatment controls the immediate damage.
But only vaccination – especially with a proven live vaccine like Salgen – delivers lasting protection for your birds and your loft.
With over 40% of pigeons naturally carrying Salmonella, vaccination is no longer optional.
It is simply part of responsible, modern pigeon management.
