Abstract

This study was carried out to evaluate the breeding values for economic traits in Korean native chicken on the basis of 11,583 birds of record along 7 generations collected from 1995 to 2001 at National Livestock Research Institute, Korea. The results obtained are summarized as follows : The breeding value estimates of the body weights at 150 and 270 days in Dark Brown, Light Brown, Gray Brown, Black and White strains were $-16.563\~0.474\;and\;-18.836\~21.700,\;-14.714\~9.272\;and\;-23.025\~11.297,\; -25.186\~12.953\;and\;-28.368\~18.156,\;-15.549\~6.329\;and\;-18.264\~4.963,\;-10.708\~20.284\; and\;-25.112\~10.132g$, respectively. The breeding value estimates of the ages at first egg in Dark Brown, Light Brown, Gray Brown, Black and White strains were $-1.236\~0.047,\;-1.509\~0.298,\;-1.362\~0.114,\;-1.436\~0.199\;and\;-1.385\~0.718$, respectively. The breeding value estimates of the egg weight at first egg and at 270 days were $-0.105\~0.075\;and\;-0.120\~0.398,\;-0.109\~0.042\;and\;-0.205\~0.173,\;-0.166\~0.084\;and\;-0.256\~0.091,\;-0.119\~0.066\;and\;-0.051\~0.132,\;-0.112\~0.027\;and\;-0.070\~0.101g$, respectively. The breeding value estimates of the egg Production to 270 days in Dark Brown, Light Brown, Gray Brown, Black and White strains were $0.298\~l.807,\;-0.049\~l.146,\;-0.396\~l.125,\;-1.206\~l.173\;and\;-0.474\~2.641$, respectively.

본 연구는 축산연구소에서 1995년부터 2001년까지 7세대에 걸쳐 능력 검정된 11,583수에 대한 자료를 이용하여 한국 재래 닭에 대한 경제형질의 육종가를 추정한 바 그 결과를 요약하면 다음과 같다. 육종가의 추정치는 적갈색, 황갈색, 회갈색, 흑색 및 백색계통의 150일령 체중에서 각각 $-16.563\~-0.474,\;-14.714\~9.272,\;-25.186\~12.953,\;-15.549\~6.329$ 및 $-10.708\~20.284g$이었고, 270일령 체중에서 각각 $-18.836\~21.700,\;-23.025\~11.297,\;-28.368\~18.156,\;-18.264\~14.963$ 및 $-25.112\~10.132g$이었다. 산란능력의 육종가 추정치는 적갈색, 황갈색, 회갈색, 흑색 및 백색 계통의 시산일령에서 각각 $-1.236\~0.047,\;-1.509\~0.298, \;-1.362\~0.114,\;-1.435\~0.199$ 및 $-1.385\~0.718$ 일 이었고, 시산난중은 각각 $-0.105\~0.075,\;0.109\~0.042,\;-0.166\~0.084,\;-0.l19\~0.066$ 및 $-0.l12\~0.0279$ 이었고, 270일령 난중은 각각 $-0.120\~0.398,\; -0.205\~0.173,\;-0.256\~0.091,\;-0.051\~0.132$ 및 $-0.070\~0.101g$ 이었으며, 270일령 산란수는 각각 $0.298\~1.807,\;-0.049\~l.146,\;-0.396\~l.125,\;-1.205\~1.173$ 및 $-0.474\~2.641$개 이었다.
