Abstract
본 연구는 한국 토종닭의 국가 주권 확보를 목적으로 DAD-IS에 등재된 한국 토종닭 여섯 품종의 성장 및 산란 능력을 조사하고, 품종 간 특성 차이를 평가하고자 실시되었다. 시험계는 국립축산과학원 가축유전자원센터에서 보존하고 있는 한국 레그혼, 경북 아라우카나, 한국 재래종, 한국 오계, 현인닭, 그리고 횡성약닭이다. 수컷 토종닭의 생체중은 전체 조사 기간 동안 경북 아라우카나가 가장 높았고, 한국 레그혼과 한국 오계가 낮았다(P<0.0001, 수컷 횡성약닭 데이터 미포함). 암컷 토종닭의 생체중은 경북 아라우카나가 가장 높고, 횡성약닭이 연구에 이용된 모든 품종 중 현저하게 낮았다(P<0.0001). 품종 간 산란 능력 비교 결과로는 한국 레그혼 품종이 산란율이 가장 높았으며, 횡성약닭이 가장 낮았다(P<0.0001). 24∼40주령의 평균 난중은 경북 아라우카나 품종이 가장 높았으며, 현인닭이 제일 낮고 그 다음으로 횡성약닭이 낮았다(P<0.0001). 또한, 토착종의 평균 난중이 재래종보다 유의적으로 높았다(P<0.05). 산란율과 난중을 함께 고려한 산란량은 한국 레그혼이 가장 높았고(P<0.0001), 모든 재래품종과 비교하였을 때 유의적으로 높았다(P<0.05). 본 연구 결과를 종합해 보면, 성장 및 산란 능력의 품종에 의한 차이는 뚜렷하였고, 조사된 품종 중 성장 능력은 경북 아라우카나가 가장 뛰어났으며, 산란 능력은 한국 레그혼이 가장 좋았다. 이는 경제성이 뛰어난 토착종에 대한 지속적인 국가 데이터 확보와 이를 통한 국가적 주권 확보의 중요성을 암시한다.
Following the Animal genetic resource for food and agriculture (AnGR) is considered as an independent resource for the possessing country, ensuring the sovereignty of AnGR is important. The present study investigated the growth and egg production performance of six breed enrolled in DAD-IS for the purpose of securing scientific data on AnGR in Korea. A total of 323 chickens (female 181, male 142) were used in this study, with the following six breeds: Korean Leghorn (LEG), Gyeongbuk Araucana (ARA), Korean native chicken (KNC), Korean Ogye (Ogye), Hyunindak (HIL), Heongseongyakdak (HYD). The body weight of male ARA from hatching to 32 weeks of age was the highest among the breeds, and LEG and Ogye were relatively lower (P<0.0001, excluded body weight data of HYD). The body weight of female ARA was the highest and HYD was significantly the lowest among the female chicken breeds (P<0.0001). The laying percentage was the highest in LEG and was the lowest in HYD among the breeds (P<0.0001). The average egg weight from 20 to 40 weeks of age was the highest in ARA, followed by LEG and was the lowest in Ogye (P<0.0001), and the adapted breed including LEG and ARA was higher than indigenous breed (P<0.05). Egg mass production was the highest in Korean Leghorn. Collectively, these results show that ARA has the best growth ability, and LEG has the best egg production performance among the used breeds. This suggests that the adapted breed with high commercial performance is important AnGR in Korea.
