During outbreaks of notifiable diseases in poultry measures are taken to restrict the spread of the disease. Mass on-farm killing of birds using gasfilled foam is such a measure. This study examines the method and technologies involved using gas-filled foam and looks at the problems involved by scaling up the procedure. Methods and results are discussed in relation to poultry physiology and behaviour monitored during controlled studies. Recommendations are made for system design and an operational protocol is provided for practical on-farm implementation.
