为了研究棉子糖对草鱼生长和血清生化指标的影响,选取初均重(69.51±6.29)g的草鱼288尾,随机分为6组,每组3个重复,每个重复16尾鱼.对照组饲喂基础饲料,试验组分别饲喂含200、400、800、1200和2000 mg/kg棉子糖的试验饲料,试验期为70 d.结果显示:与对照组相比,1)添加棉子糖能够提高草鱼的特定生长率,降低饲料系数,其中1200 mg/kg组与其余各组差异显著(P<0.05);2)各试验组蛋白质沉积率均有所提高,但无显著差异(P>0.05);脂肪沉积率除400 mg/kg组外,其余各试验组均显著升高(P<0.05);尤以1200 mg/kg组的蛋白质沉积率和脂肪沉积率最高;3)各试验组血清甘油三酯含量显著升高(P<0.05),高密度脂蛋白、低密度脂蛋白含量均显著降低(P<0.05).由此得出:1)棉子糖能够提高草鱼对饲料的吸收利用,增强鱼体对脂肪的吸收并节约蛋白质,从而促进草鱼生长;2)棉子糖可以明显的起到调节草鱼脂质代谢的作用.

The aim of this experiment was to investigate the effects of raffinose on growth performance and biochemical indi?ces in serum of grass carp. Two hundred and eighty-eight grass carp with average body weight of (69. 51± 6. 29) g were ran?domly allocated into 6 groups with 3 replicates of 16 fish. The control group was fed with the basal diet, while trial groups were fed with the experimental diets which contained 200, 400, 800, 1 200 and 2 000 mg/kg raffinose, respectively. The ex?periment lasted for 70 days. The results showed that, compared with the control group, 1) specific growth rate and feed conversion ratio were improved by adding different levels of raffinose, and the group of 1 200 mg/kg was significantly in?creased (P<0. 05); 2) protein deposition rate was improved by adding different levels of raffinose, but the differences were not significant ( P > 0. 05) ; the fat deposition rate was also increased significantly ( P < 0. 05), except the group of 400 mg/kg; the protein deposition rate and fat deposition rate of the group of 1 200 mg/kg were the highest; 3) triglyceride was significantly improved (P<0. 05), and high-density lipoprotein, low-density lipoprotein were decreased significantly (P<0. 05). In conclusion: 1) raffinose could improve the growth performance by promoting absorption and utilization of grass carp and promote the absorption of the fat through economizing the protein; 2) raffinose could play a significant role in grass carp by regulating lipid metabolism.
