Egg Drop Syndrome (EDS)
Symptoms include a sudden drop in egg production and soft-shelled eggs. No specific treatment exists; vaccination of breeding stocks can help prevent the disease.
Omphalitis
Symptoms include unhealed, infected navels and poor growth. Management includes proper incubation and hatchery sanitation; antibiotics may be used for treatment.
Infectious Bronchitis
Symptoms include coughing, sneezing, and nasal discharge. Vaccination is the best preventive measure; antibiotics may be used to prevent secondary infections.
Blackhead Disease
Symptoms include sulfur-yellow droppings, listlessness, and darkening of the skin (hence 'blackhead'). Antiprotozoal drugs are used for treatment; management of cecal worms and good litter management helps prevent it.
Marek's Disease
Symptoms may include paralysis, irregular pupil shape, and vision impairment. Treatment is not available; prevention through vaccination is recommended.
Fowl Pox
Symptoms range from cutaneous lesions to diphtheritic membranes in the mouth. Vaccination can aid in prevention and control of the virus.
Necrotic Enteritis
Symptoms are severe diarrhea, lethargy, and necrosis of the intestines. Prevention includes good management and diet; antibiotics may help during outbreaks.
Infectious Bursal Disease (IBD)
Symptoms include immunosuppression, watery diarrhea, and swelling of the bursa of Fabricius. Vaccination is critical for prevention.
Infectious Coryza
Symptoms are swelling of the face, nasal discharge, and foul-smelling discharge from the nostrils. Antibiotics can help manage the disease; vaccination for prevention.
Newcastle Disease
Symptoms involve respiratory distress, nervous manifestations, and drop in egg production. Vaccination is the primary treatment approach.
Infectious Laryngotracheitis
Symptoms cover coughing, gasping for air, and the presence of blood-stained mucus. Vaccination is the main preventive strategy; antibiotics help against secondary infections.
Aspergillosis
Symptoms encompass labored breathing, gasping, inappetence, and lethargy. Treatment involves antifungal medications and improving environmental conditions.
Mycoplasmosis
Symptoms include sneezing, nasal discharge, and chronic respiratory disease. Antibiotics may control the disease if used early; good management and biosecurity practices are recommended.
Botulism
Symptoms include flaccid paralysis and death can occur. Treatment is supportive care and antitoxin administration; preventing access to toxic carrion is crucial.
Ulcerative Enteritis
Symptoms are weight loss, ruffled feathers, and blood-stained droppings. Control methods include good husbandry and antibiotics to manage infections.
Avian Influenza
Symptoms include coughing, sneezing, respiratory distress, and sudden death. Treatment is usually not practical; focus is on prevention via biosecurity measures.
Lymphoid Leukosis
Symptoms might be difficult to observe but can include weight loss and decreased egg production. There is no treatment; prevention is through good husbandry and buying from disease-free stock.
Coccidiosis
Symptoms include bloody diarrhea, dehydration, and weight loss. Anticoccidial medication is used for treatment and prevention.
Fowl Cholera
Symptoms include swollen wattles, limping due to joint inflammation, and sudden death. Antibiotics can treat the disease, and vaccine is available for prevention.
Pullorum Disease
Symptoms are white diarrhea, poor growth, and high mortality in chicks. Treatment is not usually attempted; eradication of the disease in breeder stock is the preferred control method.
