title: [Basic principles of preventing infectious diseases in commercial poultry raising].
abstract: Stated are scientific bases of some prophylactic principles taken into consideration in the prevention of infectious diseases in industrial poultry breeding. It has been found that prophylactic activity is aimed at discontinuing the mechanism of transmission between the individual technologic groups and batches; suppressing or limiting the intensity of microbism which by itself is the dynamic state of contamination on a mass scale of the surrounding milieu with various conditionally pathogenic or saprophytic organisms; composing batches that are technologically and epizootiologically homogeneous. Stated are the principles of isolated raising according to: age and trend, black-and-white zones and ways, all in-all out, and creating pathogen-free flocks. Underlined is the necessity of constructive, technologic, and organizational conditions which are indispensable in adhering to the principles of prophylaxis.
