본 연구는 한국재래오골계의 외모형질에 대한 특징과 생장을 조사하여 품종학적인 정립과 유전적 개량 및 유전자보존을 위한 기초자료를 얻기 위하여 천연기념물 265호로 지정된 연산오골계 총 1,156수를 공시하여 실시하였다. 조사항목으로써는 우모색과 지수, 정강이와 관의 색과 정강이, 관, 우역에 따른 깃털 생장 및 생존율 등이었으며, 이들에 관한 수치들이 표의 형태로 본문에 제시되었다. 얻어진 결과들을 요약하면, 우모는 정상우에 흑색과 백색으로 구분되었으나 백색우모계의 빈도는 극히 낮고, 지색은 흑색모계에서 흑색지와 백색모계에서 백색지로 구분되고, 관은 암ㆍ수 모두 흑색계통의 단관이고, 각우가 없는 회흑색 정강이에 사지이며 흑색안을 갖는 것으로 요약된다.

More than 1,000 chickens of Korean native Yeonsan Ogolgye (Natural Monument No. 256) were used in this study in order to investigate their various external characteristics. The aims of this study were to define the Ogolgye chicken as a breed, and to provide basal data necessary for the genetic improvement of this breed. The investigated items are as follows : color of feather and toe; presense or absence of shank feather; the number of toes: color of shank and comb; the growth rates of shank, comb and feathers in various feather tracts; and finally, the livability. Data and informations were presented in tabular form in table 1 through 12. In summary, the various external traits of the Korean native Ogolgye breed can be characterized as follows. It has normal feather than silkic one as in the western type, with black color per-dominant. The frquency of white feather color is very low. The color of toes is devided into two categories; black toes in black plumage lines, and white toes in white plumage lines. Both seres have single combs with black color. The shank is gray- black and featherless. The breed has normally four toes. The eye color is black.
