Abstract

his study was conducted to determine the effect of dietary garlic supplementation on the growing performance and activity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase in broiler chicks from 3 to 5 wk post hatching. Fifty chicks were divided into 5 groups with 10 replicates per treatment and placed in a wire battery cage. Five levels of dietary garlic(0, 0.1, 0.3, 0.6 and 1.0%) were provided in an one way analysis. Feed and water were given ad libitum. Feed intake, weight gain and feed conversion rate(FCR) were not affected by the garlic supplementations. The HMG-CoA reductase activity decreased significantly(P<0.05) with the supplementation of garlic powder, compared to the garlic free group. As the dietary garlic level was increased, chicks showed decreased lipid contents in liver and blood serum. The results of this study indicate that blood cholesterol of chicks fed garlic supplemented diet might be reduced by inhibition of RMG-CoA reductase activity.

본 연구는 사료내 마늘의 첨가가 육용계의 생산성 및 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA) 환원효소에 미치는 영향을 구명하고자 실시하였다. 3주령의 육용계(Abor Acres) 50수를 처리구당 10수씩 마늘 0%, 0.3%, 0.6%, 1.0%를 첨가한 5개의 처리구에 배치하여 사료와 물은 자유채식시켰다. 사료섭취량, 중체량, 사료효율에 있어서 마늘 첨가에 의한 영향은 없었다. HMG-CoA 환원효소의 활성 및 간장과 혈청내 지질함량은 마늘 첨가에 의해 유의하게 감소되었다. 따라서 본 연구결과 마늘이 첨가된 사료를 급여한 육계의 혈액내 콜레스테롤의 감소는 HMG-CoA 환원효소 활성의 저하에 기인되는 것으로 사료된다.
