dc.description.abstractThe present study was conducted to examine the effects of evening primrose (Oenothera odorata) extract (EPE) on growth performance and carcass characteristics in broiler chickens. One hundred twelve one-day-old commercial male broilers (Indian river) were randomly distributed to five experimental groups: Control (without administration), IV (Intravascular administration), IP (Intraperitoneal administration), IV(2x) (Intravascular administration with double dose) and IP(2x) (Intraperitoneal administration with double dose). The methanolic extract of whole plant (seed/flower/leaf/stem/root) of Oenothera odorata was administered to chickens by intravascular and intraperitoneal injection during 3-7 weeks of the experiment period.
There were significant increases in body weight and weight gain in all treatment groups compared to control group at 6-7 weeks of age (p<0.05). Also, significant higher feed intake at 5 and 7 weeks of age and lower feed conversion ratio at 7 weeks were observed in EPE treatment groups (p<0.05). In addition, the administration of EPE positively influenced the carcass yields such as breast muscle and drumstick (p<0.05).
The present study suggested that the extract derived from whole plant of evening primrose had a potential for improvement of growth performance and thereby could be used as a potential growth promotor for productivity and quality of meat in broiler chickens.

dc.description.abstract달맞이꽃 추출물이 육계의 성장능력과 도체성적에 미치는 영향을 조사하기 위하여 본 연구를 수행하였다. 112수의 1일령 상용 (인디안 리버 종) 수컷 육계를 5개의 실험군으로 나누어 임의 배치하였다: 대조 (투여 없음), IV (정맥 내 투여), IP (복강 내 투여), IV(2x) (정맥 내 2배 투여), IP(2x) (복강 내 2배 투여). 달맞이꽃 (Oenothera odorata)의 전초 (종자/꽃/잎/줄기/뿌리)의 메탄올 추출액을 3-7 주의 시험기간 동안 달맞이꽃 추출물 처치군의 육계에 정맥 내 주사와 복강 내 주사의 방법으로 투여하였다.
6-7주령의 모든 달맞이꽃 추출물 처치군에서 대조군에 비하여 체중과 증체량에 유의한 증가가 있었다 (p<0.05). 또한 달맞이꽃 추출물 처치군에서 사료섭취량이 5주와 7주령에 유의하게 증가하였고, 사료 전환율은 7주령에 유의하게 감소하였다 (p<0.05). 뿐만 아니라, 달맞이꽃 추출물의 투여는 가슴육과 앞다리의 도체성적에도 긍정적인 영향을 주었다 (p<0.05).
본 연구는 달맞이꽃의 전초에서 얻어진 추출물이 육계의 성장능력을 개선하는데 잠재력이 있으며, 따라서 고기의 생산성과 품질을 위한 식물성 성장촉진제로서 이용될 수 있음을 보여 주었다.
