The Need for a Holistic View on Disease Problems in Free-range Chickens

چکیده
THE NEED FOR A HOLISTIC VIEW ON DISEASE PROBLEMS IN FREE-RANGE CHICKENS. In contrast to modern poultry production, village-based poultry production is often characterised by a range of diseases occurring at the same time. Most often free-range poultry have sub-clinical infections with a high number of endoand ecto-parasites. The significance of these infections is not known in detail, but there are some indications that parasites have an immuno-suppressive effect on the animals thus enhancing the pathogenicity of other diseases. Further, it is postulated that other diseases than Newcastle disease (ND) are present in free-range poultry production systems and that a successful development of this production system is only achieved when the exact causes of death and the effect of concurrent diseases are known.
