A paradox when the natural resources available for animal feed chickens, are sufficient and continuous available
but its immunity are often encounter problems. Small-scale chicken farms, are often get into this problem. These
type of farms are common found in many humid tropical regions, which maintained by the community of low or
middle economic level. Their hope is to improve the business to the higher scale, but in reality this expectation is
difficult to be realized because of farm health problem. In Indonesia, for example, the large scale of chicken farms is
not common when compared to the small-scale farm (Prayogi, 2011). Among the poultry farming, the native
chickens is the most promoted by the farmer in the villages (Adjid et al., 2006).
The Healt problems in small-scale poultry farmsare very generally comming from the direct contact of animals to
the ground in a semi-intensive poultry farms, which allow all animals to be infected by pathogenic microbes and
other various types of parasites. Small-scale chicken farms like this are very common cultivated by the people in the
village. The most part of this livestock type is possessed by the people in a low or middle of economic level with
their limit of skills.
