Evolution of Diseases in the Intensive Livestock Industries. Is the Poultry Industry a Viable Model?

The occurrence of disease is a direct manifestation of the failure of a production brn to provide adequate compensation for increased physiological demands on the ,iock in that system. The long term control of disease requires an holistic approach to the “ecopathology” he biosystem. The development of this approach typically follows an evolutionary cess including a number of phases that are conceptually distinct. This paper contends f the evolutionary process is sufficiently generic that empirical evidence from the lltry industry may used as a model for other intensive industries.
