[Diagnostic value of symptoms in chick embryo pathology]

The diagnostic significance (quantitative value, weight) of the symptoms in a broad sense (pathologicoanatomic, clinical, laboratory and other data) in the diseases of the bird embryo was studied. On the basis of a complex of criteria an expert rating from 1 to 4 to 342 symptoms in 58 diseases of the bird embryo was given. The interpretation of the symptoms which are evaluated, gives an opportunity for a more precise diagnosis in comparison with the classical method, in which the symptoms are not evaluated. The quantitative exactness of the diagnostic significance according to the 4th rating scale represents an important precondition for developing algorithms, planning and computerizing of the diagnostic process in the diseases of the bird embryo.
