초록

감귤 껍질 첨가 사료로 사육한 토종닭 계란이 흰쥐의 영양 대사에 미치는 영향을 조사하고자 흰쥐의 식이에 계란을첨가하지 않은 표준군(TS), 감귤 껍질을 첨가하지 않고 사육한 계란을 10% 첨가한 대조군(T0) 및 감귤 껍질을 첨가하여 사육한 계란을 10% 첨가한 감귤 껍질 급여군(T1)의 식이를 제조하였다. 이 식이들은 각각 생후 11주령의 숫쥐에 4주간 급여한 바 다음과 같은 결과들을 얻었다. 흰쥐의 체중 증가량, 식이 섭취량 및 식이 효율은 TS, T0 및 T1 사이에 유의한 차이가 없었다. 흰쥐 간의 무게는 T0 및 T1이 TS보다 유의하게 높았으나(p<0.05), 신장 및 부고환 지방의 무게는 시료들 사이에 유의한 차이가 없었다. 혈청의 총지질, 인지질, 중성지질, 총 콜레스테롤 및 LDL + VLDL-콜레스테롤 농도는 TS, T0 및 T1 사이에 유의한 차이가 없었다. HDL-콜레스테롤 및 HDL-콜레스테롤/총 콜레스테롤의 비율은 T1이 가장 높았고, 동맥경화지수는 T1이 가장 낮았다(p<0.05). 혈청의 총 단백질 농도는 TS가 T0 및 T1보다 유의하게 낮았으며, 알부민 농도는 T1이 가장 높았다(p<0.05). 알부민/글로불린의 비율은 TS가 T0 및 T1보다 유의하게 높았으나, 크레아티닌 농도는 T0가 TS 및 T1보다 유의하게 높았다(p<0.05). 그러나 혈당 및 혈색소의 농도는 TS, T0 및 T1 사이에 유의한 차이가 없었다. 그리고 $\gamma$-GTP는 T1이 가장 낮았으며(p<0.05), ALT, AST 및 ALP는 TS, T0 및 T1 사이에 유의한 차이가 없었다. 이와 같이 감귤 껍질을 급여한 계란이 흰쥐의 지질 조성, 단백질 농도, 혈당, 헤모글로빈 함량 및 효소 활성에서 정상 수준을 유지하여 감귤 껍질의 양계 사료로서의 가능성이 기대되며, 고품질 양계산물의 생산도 가능하리라 사료된다.

In this experiment, three different diets were produced to investigate the effects of Jeju native chicken eggs fed with citrus peel on the profiles of rats. The first diet did not contain any eggs (TS), the second diet contained 10% eggs and no citrus peels (T0), and the third diet contained 10% chicken egg with citrus peels (T1). These diets were provided to 11-week-old male rats for four weeks. The weight gain, feed intake and feed efficiency were not significantly different between the three treatment groups, TS, T0, and T1. The weight of the liver was significantly higher in T0 and T1 than TS (p<0.05), but the weights of the kidney and epididymal fat pad were not significantly different between the TS, T0, and T1 groups. The total lipid, phospholipid, triglycerides, total cholesterol and LDL cholesterol did not significantly difference among the TS, T0, and T1 groups. The HDL cholesterol and HDL cholesterol/ total cholesterol of T1 were the highest among the groups, and the atherogenic index of T1 was the lowest among the groups (p<0.05). The total protein of TS was significantly lower in T0 and T1, and the albumin of T1 was the highest among the groups (p<0.05). The albumin/globulin ratio of TS was significantly higher in T0 and T1, but the creatinine of T0 was significantly higher in T0 and T1 (p<0.05). The blood sugar and blood pigment were not significantly different between the TS, T0, and T1 groups. The $\gamma$-GTP of T1 was the lowest among the groups (p<0.05), but the ALT, AST and ALP did not show significant difference among the TS, T0, and T1 groups.
