Hitherto, the classification of the teratology of chick embryo which died during the normal incubating condition has been made on the basis of major deformities even if the abnormal structures were found in several parts of body. By a close examination of large numbers of abnormal embryos it was indicated that the deformities could not be classified into a limited number of types. The importance to inspect and describe systematically the variouse abnormalities was postulated. The items for such a systemic inspection were proposed.A card with those items for checking may enable even the not well trained examiners to inspect the teratology of many chick embryos. This inspecting system may provide the facilities for study of deformities of chick embryo in the ordinary local poultry breeding stations and contribute for the accumulation of the basic data on the occurence of abnormal development. |
