Quail farming is an emerging industry that offers benefits such as high productivity, fast growth rates, and low space requirements. However, just like other poultry species, quails are susceptible to various diseases that can negatively impact growth, egg production, and overall health. Understanding common quail diseases, their symptoms, causes, prevention, and treatment methods is essential for maintaining a healthy flock and ensuring farm profitability.
This article provides an in-depth look at the most common diseases affecting quails, how to prevent them, and available treatment options.

Common Bacterial Diseases in Quails
a) Ulcerative Enteritis (Quail Disease)
Cause: Clostridium colinum bacteria.
Symptoms:
Loss of appetite and weight loss.
Watery or bloody diarrhea.
Depression and ruffled feathers.
High mortality rate, especially in young quails.
Treatment:
Use of antibiotics like Bacitracin, Penicillin, or Tetracycline in drinking water.
Proper sanitation and biosecurity measures.
Prevention:
Maintain a clean environment and proper waste disposal.
Avoid overcrowding and provide stress-free conditions.
Use probiotics to improve gut health.

b) Colibacillosis (E. coli Infection)
Cause: Escherichia coli bacteria.
Symptoms:
Diarrhea and dehydration.
Swollen joints and respiratory distress.
Reduced egg production in layers.
Death in severe cases.
Treatment:
Antibiotics such as Enrofloxacin, Tylosin, or Neomycin.
Electrolyte therapy to prevent dehydration.
Prevention:
Maintain clean water and food sources.
Proper ventilation and hygiene in housing.
c) Salmonellosis (Pullorum Disease)
Cause: Salmonella pullorum bacteria.
Symptoms:
White diarrhea in young chicks.
Weakness and reduced activity.
Swollen liver and spleen.
Increased mortality rate in chicks.
Treatment:
Antibiotics like Furazolidone and Sulfa drugs.
Supportive therapy with vitamins and electrolytes.
Prevention:
Implement strict hygiene and biosecurity protocols.
Source chicks from disease-free hatcheries.
Vaccination programs where applicable.
Common Viral Diseases in Quails
a) Newcastle Disease
Cause: Newcastle disease virus (NDV).
Symptoms:
Respiratory distress (coughing, sneezing).
Twisted neck and paralysis.
Drop in egg production.
Greenish diarrhea.
Treatment:
No specific cure; supportive care and antibiotics for secondary infections.
Prevention:
Vaccination at an early age.
Proper biosecurity and controlled farm access.
b) Quail Pox
Cause: Avipoxvirus.
Symptoms:
Scab-like lesions on the face, beak, and legs.
Respiratory distress in wet forms of the disease.
Reduced feeding and egg production.
Treatment:
No specific treatment; apply iodine or antiseptics to lesions.
Provide vitamin A and multivitamins for immune support.
Prevention:
Vaccination against fowl pox.
Reduce mosquito populations, as they transmit the virus.

c) Infectious Coryza
Cause: Avibacterium paragallinarum bacteria.
Symptoms:
Swelling around the eyes and face.
Nasal discharge and sneezing.
Difficulty breathing.
Drop in egg production.
Treatment:
Antibiotics like Streptomycin and Sulfadimethoxine.
Prevention:
Maintain dry and clean bedding.
Quarantine new birds before introducing them to the flock.
Common Parasitic Diseases in Quails
a) Coccidiosis
Cause: Eimeria species (intestinal parasites).
Symptoms:
Bloody diarrhea and dehydration.
Loss of weight and ruffled feathers.
Reduced feed intake and weakness.
Treatment:
Coccidiostats such as Amprolium and Sulfaquinoxaline in drinking water.
Provide electrolyte therapy to counter dehydration.
Prevention:
Use anticoccidial feed additives.
Keep litter dry and clean.

b) Lice and Mites Infestation
Cause: External parasites such as Dermanyssus gallinae.
Symptoms:
Feather loss and irritation.
Restlessness and reduced egg production.
Visible mites on the skin.
Treatment:
Dusting powders containing Permethrin or Malathion.
Neem oil or Diatomaceous earth as organic alternatives.
Prevention:
Regularly clean and disinfect the coop.
Avoid overcrowding.
c) Worm Infestation
Cause: Internal parasites such as roundworms and tapeworms.
Symptoms:
Weight loss and poor growth.
Diarrhea and reduced feed efficiency.
Treatment:
Deworming with Levamisole, Piperazine, or Ivermectin.
Prevention:
Rotate grazing areas and maintain sanitary conditions.
Prevention and Biosecurity Measures
Prevention is more effective and economical than treating diseases. Here are key biosecurity measures:
a) Good Hygiene Practices
Regular cleaning and disinfection of cages, feeders, and drinkers.
Proper disposal of manure and waste.
b) Quarantine New Birds
Isolate new birds for at least two weeks before introducing them to the flock.
c) Vaccination Programs
Follow a vaccination schedule for Newcastle disease, Quail pox, and Infectious bronchitis.
d) Proper Feeding and Nutrition
Provide balanced diets with adequate vitamins and minerals to boost immunity.
e) Control of Vectors and Rodents
Prevent mosquitoes, mites, and rats, as they can spread diseases.
f) Limit Farm Visitors and Equipment Sharing
Restrict access to essential personnel only to reduce disease introduction.
Conclusion
Understanding and managing common quail diseases is essential for successful quail farming. By implementing preventative measures, proper hygiene, vaccination, and timely treatment, farmers can ensure healthy and productive flocks.
A well-maintained biosecurity system, combined with good feeding practices and veterinary care, is the best strategy to reduce mortality rates and maximize production efficiency.
