| 摘 要： | 分别用0%(对照组)、4%、8%和12%玉米蛋白粉替代饲料中0%、33.33%、66.67%和100%的鱼粉配制4种等氮、等能的试验饲料,在室内循环养殖系统中饲养初始体质量为(13.68±1.77)g异育银鲫60d,研究玉米蛋白粉替代鱼粉对异育银鲫生长的影响,同时以15d为采样间隔研究鱼体血清中三碘甲腺原氨酸(T3)和甲状腺素(T4)含量的变化。结果表明:对照组与8%替代组的饲料系数无显著差异,且均显著低于4%和12%替代组;玉米蛋白粉对异育银鲫生长无显著影响;饲养30到60d对血清中T3含量无显著影响,而15d对照组血清中T3含量显著高于其余各替代组;30d时4%和8%替代组血清中T4含量与对照组无显著差异,而12%替代组显著低于对照组,而60d时与对照组无显著差异;60d时,各组鱼体的生长与T3、T4含量变化趋势相同。在本实验条件下,玉米蛋白粉在异育银鲫饲料中的适宜用量为4%～8%,对鱼粉的适宜替代量为33.33%～66.67%。 |

| Abstract: | An experiment was conducted to evaluate the use of corn gluten meal(CGM) as a dietary protein for Carassius auratus gibelio.Four kinds of isocaloric,isonitrogenous diets were formulated to contain 0%(control),4%,8% and 12% of corn gluten meal(CGM),replacing 0%,33.33%,66.67% and 100% of fish meal respectively.The fish with initial average body mass of(13.68±1.77) g were fed in a recirculation aquaculture system indoors for 60 days.The growth,serum triiodothyronine(T3) and thyroxine(T4) contents of C.auratus gibelio were determined.The results showed that feed conversion ratio(FCR) of control and 8% CGM groups were significantly higher than that of 4% and 12% CGM groups(P<0.05).CGM did not significantly affect on growth of allogynogenetic silver crucian carp.CGM did not significantly affect T3 content in serum from 30th to 60th day,but T3 content of the control group was significantly higher than the other groups(P<0.05) in 15th day.During the first 30 days in the experiment,T4 content in serum of the control group was significantly higher than that of 12% CGM group,but had no significant difference compared with 4% and 8% CGM groups.There were no significant effects on T4 contents among each group in 60th day.At the end of the feeding test,the growth and T3,T4 contents in serum of C.auratus gibelio among four groups had same trends.All the results indicate that the appropriate dosage of CGM is 4%-8%,replacing 33.33%-66.67% of fish meal of the diets in this experiment. |
