What is Poultry Disease?
Poultry Disease is defined as the deviation from the normal state of health which may be characterized by impaired body functions, a decrease in production, mortality, and morbidity of the poultry population
Introduction of poultry diseases
Poultry diseases are susceptible to birds which are in several types of infectious and/or non-infectious diseases. The most common infections are a virus, bacteria, fungus, protozoa, Mycoplasma, Rickettsia, and chlamydia. This infectious causing disease is the same as human beings.
Sometimes, Poultry viral diseases are causing higher mortality due to respiratory infection, enteritis, bloody diarrhea, paralysis, and prostration. above mention, clinical sign cause huge production losses and enhance the production cost
Poultry disease Classification
There are ways, we can classify the poultry diseases. Such as based on infectious category, organ, body system, symptoms. But broadly, we can divide into two classes
1. Infectious disease
It is defined as a disease caused by the live pathogen or microorganism. such as virus, bacteria, fungus, etc. according to the spread of disease, infectious diseases are classified into three groups.
- Contagious disease
It is defined as a disease that can be spread to one place to another place by the physical and non-physical means. For instance, Avian Influenza spread pandemically inside the country and worldwide by the airborne transmission. It also spread by infected birds, humans, vehicles, etc.
- Non-Contagious disease
It means the disease which does not transmit to one location to another location by any means. Such as brooder pneumonia is a non- contagious disease in poultry Because it can not transmit from one person to another person or another place.
- Zoonotic disease
Zoonotic disease refers to a disease which transmits from the animal to human. For instance, Newcastle disease found in poultry only. But it can be transmitted to humans causing conjunctivitis.
- Non-infection disease
Non-infection disease defined as a disease caused by non-infectious agents. such as vitamin and mineral deficiency belong to this group. hypocalcemia, cage layer fatigue, fatty liver syndrome, etc.
The most common Poultry diseases
Poultry diseases are originated mainly from the six infectious agents and non-infectious groups. We can discuss the categories in a separate from
A) Viral diseases
B) Bacterial Diseases
