The diseases that are of the highest risk of accidental intro- duction into farms are denoted by ». These pathogens possess inherent properties of high transmissibility, and have enhanced resistance to inactivation (loss of infectivity) due to environmen- tal temperature and sunlight. Such pathogens therefore tend to occur more frequently on poultry sites. Table 2 summarizes the major route(s) of transmission for each of the major pathogens. Knowing the means of spread of any pathogen is fundamental to the development of a plan of action to prevent spread of the pathogen and outbreak of the disease within a production site.

Range Poultry Housing Livestock Production Guide By Robert Plamondon Edited by Anne Fanatico and Richard Earles NCAT Agriculture Specialists June 2003 Experienced pastured-poultry producer Robert Plamondon 1 discusses housing designs for outdoor production. Introduction In this document I will describe housing designs that give chickens access to green plants in yards or pastures as opposed to confinement or bare-yard systems. There are a variety of housing styles commonly used for ranged chickens each of which is associated with a particular management style that I will also describe. My wife Karen and I have been raising free-range hens in Oregon since 1996 and pastured broilers since 1998. We have 700 hens and will raise over 1 500 broilers this year. We have tried many different techniques and I hope this will allow me to speak clearly about the key points and trade-offs in each of the major range management styles. I discuss a variety of housing types in this document. I ve necessarily placed an emphasis on the ones I have used myself since I have a better understanding of these. The detail or sketchiness of different sections will generally correspond to the amount of hands-on experience I have with a particular style and shouldn t be interpreted as a value judgment.
