A General Overview of Poultry Diseases

Poultry diseases are a big problem for chickens and other birds raised on farms all over the world. These diseases can make birds sick, which affects their health and reduces how many eggs or how much meat they produce. It is important to learn about the different types of diseases, what their symptoms are (the signs of sickness), and how to prevent them to keep poultry healthy. This guide explains the main types of poultry diseases, common symptoms to watch for, and simple ways to help prevent these illnesses.

Classification of Poultry Diseases

• How they affect poultry: These can cause anything from mild to serious infections.
• Examples:
  • Salmonellosis: Can cause diarrhea and make birds weak.
  • Colibacillosis: Often causes breathing problems.
  • Mycoplasmosis: This can lead to breathing issues and swollen eyes.

Fungal Diseases

• What they are: Diseases caused by fungi (a type of mold).
• How they affect poultry: Usually affect the lungs or skin.
• Examples:
  • Aspergillosis: Causes breathing problems.
