초록

본 시험은 육계에 뽕잎과 민들레 추출물을 각각 1%와 2%를 급여하여 5주간 사육한 육계의 생산성과 계육의 일반성분, 가열 감량, 육즙 손실 및 혈액성상을 조사하였다. 실험구는 뽕잎과 민들레 추출물을 급여하지 않은 대조구, 뽕잎 추출물 1% 급여구는 T1, 뽕잎 추출물 2% 급여구는 T2, 민들레 추출물 1% 급여구는 T3 그리고 민들레 추출물 2% 급여구를 T4 등 5개 처리구로 나누어 4주간 냉장 온도($4{\pm}1^{\circ}C$)에서 저장하면서 실험하였다. 육계의 증체량 및 사료 요구율은 T2가 유의적으로 높았다. 가열 감량은 저장 기간이 경과하면서 증가하였고, 처리구간에는 유의성이 없었다. 육즙 손실은 저장기간이 지남에 따라 증가하였으며, 뽕잎과 민들레 추출물의 급여는 육즙 손실이 감소되는 경향이나 유의성은 없었다(P>0.05). 혈액 조성 중 GOT, GPT, 총콜레스테롤은 뽕잎과 민들레 추출물 급여구에서 낮아지고, 특히 민들레 추출물 2% 급여구에서(T4) 유의적으로 감소하였다(P<0.05). HDL-cholesterol은 대조구보다 T1, T2, T3 및 T4에서 증가하고, 특히 T3와 T4에서 유의적으로 증가하였다(P<0.05). LDL-cholesterol은 처리구간에 유의성이 없었다. 중성지방은 대조구와 T1 및 T3는 유의적인 변화가 없었으며, T2와 T4에서 유의성 있게 낮아졌다(P<0.05). 결론적으로 민들레 추출물 2% 급여는 총콜레스테롤, 중성지방을 감소시키고, HDL-cholesterol을 증가 시킴으로 혈액 조성을 개선할 가능성이 있는 것으로 판단된다.

This study was conducted to investigate the effects of dietary supplementation of mulberry leaves and dandelion extracts on performance, proximate composition, heating loss, drip loss, and blood characteristics of chickens. One hundred sixty broiler chicks were fed diets for five weeks containing 1% mulberry leaves extracts (T1), 2% mulberry leaves extracts (T2), 1% dandelion extracts (T3), and 2% dandelion extracts (T4). At the end of five week feeding experiment, broiler were slaughtered, and stored at $4^{\circ}C$. T2 resulted in much better weight gain and feed conversion than other treatment groups. As storage time increased, all treatment groups resulted in increased heating loss and drip loss (P<0.05) but no significant difference were observed among the treatment groups. In blood composition, GOT (glutamic oxaloacetate transaminase), GPT (glutamic pyrubic transaminase), total cholesterol, and triglyceride were significantly decreased by the supplementation of mulberry leaves and dandelion extracts compared to the control (P<0.05). Especially, T4 was significantly (P<0.05) more effective in improving blood composition compared to other treatment groups. However, no significant difference (P>0.05) were found in LDL-cholesterol among all treatment groups. In conclusion, these data indicate that compared to other treatments, supplementation of 2% dandelion extracts (T4) were most effective in decreasing total cholesterol and triglyceride and increasing HDL-cholesterol.
