English, abstract: Poultry provide globally important sources of
animal protein and are amongst the most intensively reared of all
livestock species. Diseases of poultry are therefore of major
concern, both locally and on an international scale. Poultry
production have been brought to the edge, because of the large
numbers of infectious diseases outbreaks; that strikes the poultry
farms from time to time in the absence of good hygiene. It is also
important to consider the concept of, and the need for, biosecurity
or the range of management procedures designed to protect livestock
from infection. The low productivity in traditional systems is
mainly due to high mortality, which is caused by mismanagement,
diseases, lack of nutritional feeding and predators. In traditional
systems the mortality has been estimated to be in the range of 80 -
90% within the first year after hatching, (Permin and Bisgaard,
1999). Diagnosis, treatment and/or prevention of diseases are of
major importance to any attempts at increasing productivity.
Backyard poultry production systems (BPS) are an important and
widespread form of poultry production. There is a common perception
that biosecurity standards in BPS are generally poor and BPS are
usually associated with poultry diseases and zoonoses,
(Hamilton-West, et al, 2011) The structure of the poultry meat and
egg production industries provides both challenges and
opportunities in the area of poultry health; one of these
challenges is the existence of very high-density populations of
commercial poultry. Such circumstances provide an ideal medium for
multiplication and spread of all kinds of micro-organisms including
pathogens, such as Salmonella spp that can strike all ages
specially chicks and still considered one of the most important
