초록

다기능성 지질물질로 알려진 CLA가 육계의 증체 및 체지방 대사작용에 미치는 영향을 조사하기 위하여, 대조구인 CORN(corn oil 1.5%), CLA I(corn oil 0.75%+CLA 0.75%) 및 CLA II(CLA 1.5%) 등 3 처리구를 설정하여 증체, 사료요구율, 혈중 생화학적 성분과 leptin 및 체 조직의 leptin mRNA 수준에 대하여 조사하였다. 본 시험 결과, CLA 첨가에 따른 체중, 일당 증체량 및 사료요구율 등은 통계적으로 유의한 영향을 받지 않았다. 또한 간, 소장, 췌장 및 체지방(복강 및 넓적다리 지방)의 상대적 무게 역시, CLA 첨가에 따른 유의적 효과가 없었다. 혈중 glucose, triglyceride 및 cholesterol 수준은 대조구인 CORN구에 비해 CLA 1.5% 급여구에서 유의적(P<0.05)으로 감소하였으나, NEFA는 모든 구에서 비슷한 수준을 보였다. CLA 첨가사료 급여는 간 조직내 total lipid 및 NEFA 함량을 유의적으로(P<0.05) 감소시키고, triglyceride 수준은 통계적 차이는 없었지만 CLA II구에서 약 23% 감소하는 경향이 있었다. 혈중 leptin은 대조구에 비해 CLA I 및 II구에서 감소하는 경향이 있었으나, 유의적 차이는 없었다. 간 및 복강지방 조직내 leptin mRNA 발현은 CLA II구에서 대조구에 비해 유의적(P<0.05)으로 감소되었다. 이러한 결과로 보아, 사료내 1.5% 수준의 CLA 첨가는 간 조직의 지방대사 경로에 유의적인 영향을 미칠 수 있는 것으로 사료된다.

Abstract

The current study was conducted to investigate the effects of dietary conjugated linoleic acid(CLA) on growth performance and body fat metabolism in broiler chickens. A total of 48 male birds aged 3 days were randomly allotted into three dietary groups; CORN(corn oil 1.5%), CLAⅠ(corn oil 0.75%+CLA 0.75%) and CLA II(CLA 1.5%) groups. After feeding commercial diet ad libitum for 3 weeks, eight selected birds on the basis of body weight were housed, two birds in a cage, and continuously given ad libitum corresponding experimental diet for another 2 weeks. As a result, dietary addition of CLA did not influence on body weight, gain and feed conversion rate. The relative weights of the liver and deposited fats(abdominal and thigh fat pads) were not also affected by the dietary treatments. Serum glucose, triglyceride and cholesterol levels markedly(P<0.05) decreased in CLA II compared with those in CORN group. However, serum nonesterified fatty acid(NEFA) was not altered by dietary CLA. Serum leptin level was tended to be decreased by dietary CLA without statistical difference. The diet supplemented with CLA caused a significant(P<0.05) decrease in hepatic total lipid and NEFA without changing triglyceride level. Also, feeding dietary CLA at the level of 1.5% reduced leptin mRNA expression in the liver and abdominal fats compared with feeding corn oil. In conclusion, our results suggest that dietary 1.5% CLA may affect, at least in part, lipid metabolism in the liver of broiler chickens.
