| 摘 要： | 选用牛磺酸作为饲料添加剂,以0.2%、0.4%、0.6%、0.8%的剂量将牛磺酸添加到基础饲料中,以基础饲料为对照饲喂鲫鱼(45￣52g)15d后,测定蛋白质消化吸收率。结果表明:牛磺酸可以显著提高鲫鱼对蛋白质的消化吸收率(P<0.05),其中,添加0.60%组效果最佳,比对照组提高6.65%。蛋白质消化率的提高,是牛磺酸促进鱼体生长速度加快的主要原因之一。

| Abstract: | Crucian carp (body weight 45~52 g) was fed by formalated diet which added with taurine at different levels of 0.20%,0.40%,0.60%,0.80%,respectively. Protein digestibility was determined in 15 days.The result showed that taurine significantly increased crucian carp's protein digestibility(P<0.05). The protein digestibility of the group fed on formulated diet which added with taurine at levels of 0.6% was 6.65% higher than that of the control. Promotion of protein digestibilities was an important factor to increase fish growth. |
