Bacterial Diseases
These are diseases caused by bacteria which are simple, single-cell microorganisms. They can be easily found. Examples of bacterial diseases include fowl cholera, typhoid, contagious abortion, mastitis, tuberculosis, anthrax, etc.
Viral Diseases

Conclusively, when diseases in farm animals are not adequately controlled, they cause a huge economic loss. Managing diseases effectively requires large sums of money, time, and other resources.
