Common Poultry Diseases and Their Treatment

Common Poultry Diseases and Their Treatment: A Farmer’s Guide

Raising healthy poultry is every farmer’s goal, but even with the best care, diseases can strike. Poultry illnesses not only reduce egg and meat production but can also spread quickly through a flock if left untreated. As a poultry farmer, knowing the common poultry diseases and their treatments can save you from costly losses.

In this guide, we’ll look at the most frequent poultry diseases, their symptoms, and how you can prevent and treat them.

1. Newcastle Disease (ND)

Cause: A highly contagious virus.

Symptoms: Sneezing, coughing, twisted necks, greenish diarrhea, sudden drop in egg production.

Treatment:

There is no direct cure. Vaccination is the most effective method.

Infected birds should be isolated to prevent spreading.

Provide supportive care with clean water, vitamins, and electrolytes.

Prevention Tip: Always vaccinate chicks at an early age and maintain strict biosecurity on your farm.

2. Infectious Bursal Disease (Gumboro)

Cause: Viral infection common in young birds (3–6 weeks old).

Symptoms: Depression, ruffled feathers, watery diarrhea, trembling.

Treatment:

No specific cure exists, but good management helps.

Give multivitamins (especially Vitamin C and K) to reduce mortality.

Keep birds hydrated and stress-free.

Prevention Tip: Vaccinate at the right age and maintain good hygiene in the poultry house.

3. Coccidiosis

Cause: Parasite (protozoa) that thrives in wet litter.

Symptoms: Bloody droppings, weakness, weight loss, drooping wings.

Treatment:

Final Thoughts

Every poultry farmer should understand the common poultry diseases and their treatments. While some infections have no cure, prevention through vaccination and good farm management is the key to success. Always consult a qualified veterinarian before administering any treatment, and invest in biosecurity—it’s cheaper than treating a sick flock.

With the right knowledge, you can keep your chickens healthy, productive, and profitable.
