This paper describes the production of specific-pathogen-free chicks at the research station over a five-year period. The birds are housed in commercial-type, controlled environment houses, and the aim has been to eliminate, by management, infectious bronchitis, avian encephalomyelitis. M. gallisepticum, Staph. aureus, Salmonella and pathogenic strains of E. coli. The flock has been freed from M. gallisepticum, salmonella and CELO virus; it has also been possible to produce RIF-free birds.
