FOWL CHOLERA IN POULTRY: SIGNS, CAUSES, AND EFFECTIVE TREATMENT
Fowl cholera in poultry is one of the most dangerous infectious diseases commonly found in chickens, ducks, geese, and other waterfowl. The disease spreads rapidly, causes high mortality rates, and leads to severe production losses if not detected and treated promptly.
So, what causes fowl cholera in poultry? How can it be recognized early and treated effectively? Let’s explore in detail below.
What is fowl cholera in poultry?
Fowl cholera is an infectious disease caused by the bacterium Pasteurella multocida. This bacterium can survive in the farming environment, drinking water, feed, or in carrier animals that show no symptoms.
When weather conditions change suddenly, immunity is weakened, or farm hygiene is poor, the bacteria multiply rapidly and spread across the flock.
The disease can affect poultry at any age but is more common in adult birds and densely stocked flocks.
Causes of fowl cholera in poultry
Several factors increase the risk of outbreaks:
Poor hygiene and damp housing conditions
High stocking density
Sudden weather changes, especially during rainy seasons or seasonal transitions
Contaminated feed and drinking water
Stress due to transport or environmental changes
Incomplete vaccination programs
These conditions create an ideal environment for bacterial growth and rapid transmission.
Signs of fowl cholera in poultry
Symptoms vary depending on disease severity.
Peracute form
This is the most dangerous form:
Sudden death without obvious symptoms
In some cases, high fever before death
Acute form
Common signs include:
Loss of appetite and lethargy
High fever (42–43°C / 107–109°F)
Difficulty breathing, rapid breathing
Nasal discharge
Bluish comb and wattles
Green or yellow diarrhea
Death within 1–3 days if untreated
Chronic form
Typical symptoms include:
Joint inflammation and lameness
Swelling of head and face
Sinusitis
Stunted growth
Reduced egg production
Typical lesions observed during necropsy
When examining dead birds, common findings include:
Enlarged liver with gray-white necrotic spots
Hemorrhages in the heart and myocardium
Congested lungs
Enlarged spleen
Petechial hemorrhages in abdominal fat
These lesions help confirm the disease diagnosis.
How does fowl cholera spread?
Pasteurella multocida can spread through:
Direct contact with infected birds
Contaminated feed and water
Unclean equipment and farming tools
Wild birds and rodents
Farm workers moving between poultry houses without biosecurity measures
Because of its rapid transmission, early detection and control are extremely important.
Effective treatment of fowl cholera in poultry
When disease is suspected, farmers should apply multiple measures:
Isolate infected birds
Separate sick birds immediately to prevent spreading to healthy flocks.
Use appropriate antibiotics
Depending on veterinary guidance, VietVet provides several treatment solutions such as:
SULTRIM INJ
FLOVET ORAL
CEFAXIM NEW
These products help control bacterial infections caused by susceptible pathogens, including fowl cholera.
Supplement vitamins and electrolytes
Support recovery and immunity:
Vitamin C (15%) helps reduce stress, boost immunity, and improve recovery
Gluco K.C Electrolyte – Ginseng helps restore energy, balance electrolytes, and reduce dehydration
These supplements improve feed intake and speed up recovery.
Disinfection and farm sanitation
Disinfect the entire farm area:
Poultry houses
Walkways
Feeders
Drinkers
Waste and manure areas
This helps reduce environmental bacterial load.
Prevention of fowl cholera in poultry
Prevention is more effective and economical than treatment.
Vaccination
Proper vaccination helps build immunity and reduce outbreak risk.
Biosecurity measures
Restrict visitors to farm areas
Disinfect vehicles and equipment regularly
Quarantine new birds before mixing with the flock
Proper nutrition
Balanced feed improves immunity and resistance to disease.
Regular cleaning
Remove manure frequently
Keep housing dry
Control insects and rodents
Economic losses caused by fowl cholera
If not controlled, the disease can cause:
High mortality rates
Reduced growth performance
Decreased egg production
Increased treatment costs
Significant economic losses for farms
Large-scale farms may suffer losses worth tens to hundreds of millions VND per outbreak.
Fowl cholera in poultry is a highly contagious disease that spreads quickly and causes severe economic damage. Early detection, proper treatment, and preventive vaccination programs are essential to protect poultry flocks.
Combining treatment solutions such as those from VietVet with strict biosecurity practices will significantly improve disease control efficiency and farm productivity.
