The avian respiratory system is particular in many ways. First of all it is equipped with a unique set of so-called "air sacs" which are a collection of thinwalled bubble-like pockets that work as a system to circulate oxygen throughout the body. Because they're poorly irrigated it's very hard to rech them with classical theraputics like antibiotics who must travel through the blood....Also, in contrast to the mamalian respiratory system, birds have a relatively much lower number of free surface pulmonary macrophages.
Besides, and in some cases, due to this extraordinary design many viral and baterial diseases in poultry use this same respiratory system as port of entry, so keeping this system in optimal form and health state is like a must for anybody working with poultry on a professional level.
