BROILER CHICKEN SICKNESSES: Identification, Treatment, and Prevention
Broilers are susceptible to various diseases due to their rapid growth and environmental conditions. Below is a guide to common broiler diseases, symptoms, treatments, and prevention strategies.
1. Coccidiosis
Cause: Parasitic protozoa (Eimeria species).
Symptoms:
Bloody or watery diarrhea.
Lethargy and loss of appetite.
Drooping wings and ruffled feathers.
Treatment:
Administer Amprolium or Sulfaquinoxaline in drinking water for 3β5 days.
Use Toltrazuril (Baycox) for severe cases.
Prevention:
Keep litter dry and clean.
Add anti-coccidials like Amprolium to water weekly as a preventive.
Rotate litter regularly to reduce parasite load.
2. Newcastle Disease
Cause: Newcastle Disease Virus (NDV).
Symptoms:
Greenish diarrhea.
Respiratory distress (gasping, coughing).
Twisting of the neck (torticollis).
Treatment:
No cure; supportive treatment with Multivitamins and antibiotics for secondary infections.
Prevention:
Vaccinate at Day 7 and Day 21 (Lasota).
Strict biosecurity to prevent virus introduction.
3. Infectious Bursal Disease (Gumboro)
Cause: Virus affecting young broilers (1β6 weeks).
Symptoms:
Ruffled feathers, reluctance to move.
White or watery diarrhea.
Swollen cloaca.
Treatment:
No direct treatment; administer Multivitamins and electrolytes for recovery.
Use antibiotics to prevent secondary infections.
Prevention:
Vaccinate at Day 14 and booster on Day 28.
Maintain clean and disinfected housing.
4. Chronic Respiratory Disease (CRD)
Cause: Mycoplasma bacteria, often linked with poor ventilation.
Symptoms:
Nasal discharge and watery eyes.

6. Infectious Coryza
Cause: Bacteria (Haemophilus paragallinarum).
Symptoms:
Swollen face and eyes.
Nasal discharge and foul smell.
Reduced feed intake and weight gain.
Treatment:
Use Tylosin, Erythromycin, or Sulfa drugs in water.
Prevention:
Maintain clean housing and avoid overcrowding.
Isolate sick birds immediately.
7. Fungal Infections (Aspergillosis)
Cause: Fungal spores from damp litter or feed.
Symptoms:
Gasping and respiratory issues.
Weakness and reduced growth.
Treatment:
No direct treatment; administer Copper sulfate in water.
Remove and replace moldy litter and feed.
Prevention:
Store feed in a dry place.
Regularly replace wet or damp litter.
8. Heat Stress
Cause: High environmental temperatures.
Symptoms:
Panting and spreading of wings.
Reduced feed intake and growth.
Treatment:
Provide Electrolytes (e.g., Stress pack) in water.
Increase ventilation and reduce stocking density.
Prevention:
Install fans or wet curtains in the poultry house.

This is a very big INSULT to the great people of OSUN...

@davido@AAdeleke_01 lets show the world how shameless those AMBO squad is
Aregbesola did not promote any Osun state worker in his 8yrs even while paying them half salaries for 4yrs.
Oyetola came, did promotions once without renumeration. Wetin be the meaning of that one?
Osun State Local Government have been in a comatose in the last 12-16yrs. Gone are those days people go to their LGAs to ask for replacement of a faulty transformer here.
Local Government Offices have been shut or partially opened since February 2025 because we now have 2 sets of Chairmen fighting for the offices here.
Omoor, the State is b leeding o, courtesy of APC.
