Abstract

Effects of dietary taurine on the abdominal fat weight and serum and liver concentrations of cholesterol were investigated with male broiler chicks. One-day old chicks were allocated to one of three taurine supplemented diets: 0 (control), 1 and 2%. Body weight gain of chicks fed the diet supplemented with 2% taurine decreased by 6% compared to the control (P$\prec$0.05). However, feed conversion ratio was not different among treatments. Liver weight and ratio of liver weight to body weight showed no difference among treatments. Abdominal fat weights were lower in 1% and 2% taurine supplementations by 14% and 20%, respectively, than that of the control (P$\prec$0.05). Serum concentrations of triglyceride, glucose, glutamic oxaloacetic transaminase and glutamic pyruvic transaminase were not different among treatments. However, serum concentrations of total cholesterol were higher in 1% and 2% taurine supplementations by 10% and 12%, respectively, than that of the control (P$\prec$0.05). Also serum concentrations of HDL-cholesterol increased in 1% and 2% taurine supplementations by 20% and 34%, respectively, compared to the control (P$\prec$0.05). Concentrations of total cholesterol in liver decreased in 1% and 2% taurine supplementation by 9% and 13%, compared to the control (P$\prec$0.05). Also concentrations of HDL-cholesterol in liver were lower in 1.0% and 2.0% taurine supplementation by 20% and 38%, respectively, than that of the control (P$\prec$0.05). These results showed that taurine supplementation decreased the fat storage in abdominal cavity and affected on the cholesterol metabolism in liver of broiler chicks.

타우린 첨가가 복강지방 및 간과 혈청 중 콜레스테롤 농도에 미치는 영향을 육계 수컷병아리에서 조사하였다. 1일령 병아리를 사료에 타우린을 첨가하지 않은 대조구와 1% 그리고 2%를 첨가한 3가지 시험구에 균일하게 분포시켰다. 2% 타우린 첨가 시 육계의 증체량은 6% 감소하였으나, 사료효율은 처리구간 차이가 없었다. 간 중량과 체중대비 간 중량도 처리구간 차이가 없었으나, 복강지방은 1%와 2% 타우린 첨가구가 대조구에 비하여 각각 14%와 20% 낮았다. 혈청 중 중성지방, glucose, GOT, 및 GPT 농도는 처리구간 차이가 없었으나, 혈청 중 총 콜레스테롤 농도는 1%와 2% 타우린 첨가구가 대조구에 비하여 각각 10%와 12% 증가하였다. HDL-콜레스테롤 역시 1%와 2% 첨가구가 대조구에 비하여 각각 20%와 34% 높았다. 간의 총 콜레스테롤 농도는 1%와 2% 첨가구가 대조구에 비하여 각각 9%와 13% 낮았으며, 간의 HDL-콜레스테롤 농도 역시 1%와 2% 첨가구가 대조구에 비하여 각각 20%와 38% 낮았다. 본 연구의 결과는 타우린 첨가가 육계의 복강지방의 축적을 억제시키며 콜레스테롤 대사에 영향을 미친다는 것을 보여준다.
