Chicken diseases and treatment pdf
Poultry Diseases and Their RemediesRemember that the respiratory system of a bird includes lungs, air sacs and hollow bones. Therefore, keep dust and ammonia levels low which will help the health and welfare of poultry since ammonia paralyses the small hairs cilia which act like an escalator to move normal mucus up the trachea before being swallowed. If these are impaired, viruses, bacteria and fungi have a greater chance of colonising the bird in its air sacs, lungs and bones and causing disease which is therefore very difficult to eradicate. Free-range birds are considered to have a high risk of infection from wild birds carrying the virus. There are several viruses that cause concern in poultry e.

Sporulated oocysts have the ability to survive outside the host for very long periods. Sporulation can continue when temperatures increase, although prolonged periods at low temperatures can destroy the viability of the oocytes. This may be an important factor for outdoor poultry systems.
