| 摘 要： | 本研究旨在确定中华鲟幼鲟对维生素C(VC)的营养需要量。配制含VC分别为0.5、59.8、119.5、239.1、478.1和956.2 mg/kg饲料的6组日粮(分别编号为C0.5、C59.8、C119.5、C239.1、C478.1和C956.2),连续投喂中华鲟幼鲟8周后,以生长速度、组织VC含量和部分相关酶活性来确定中华鲟对VC的需求量。结果表明,C0.5和C59.8组鲟鱼的增重率、饲料效率、蛋白质效率都低于C119.5组,进一步提高饲料VC含量,也没有显著变化(P>0.05);C478.1组的肝脏和肌肉组织VC含量达最高水平;C239.1组血清溶菌酶活性最高;C239.1组SOD活性最低。根据平均增重率和饲料效率做折线法分析表明,维持中华鲟最佳生长的饲料VC含量为108.5 mg/kg;肝脏中VC含量达最大时饲料VC添加量为309.4 mg/kg;肌肉中VC含量达最大时饲料VC添加量为273.3 mg/kg。 |

| Abstract: | To study optimal dietary vitamin C requirement of Chinese sturgeon(Acipenser sinensis),an experiment was carried out to determine the dietary vitamin C requirement of juvenile Chinese sturgeon(Acipenser sinensis).Six diets containing vitamin C 0.5,59.8,119.5,239.1,478.1 and 956.2 mg/kg diet(C_(0.5),C_(59.8),C_(119.5),C_(239.1),C_(478.1) and C_(956.2))were used to feed the fish for 8 weeks.The optimal dietary vitamin C requirement was evaluated based on growth performance,tissue vitamin C content and some related enzyme activity.The results showed that fish fed C_(0.5) and C_(59.8) diets had lower weight gain(WG),feed efficiency and protein efficiency rate(PER) than those of the C_(119.5) diet.With the increase of dietary vitamin C content from 119.5 mg/kg to 956.2 mg/kg,above results were not changed significantly(P>0.05).The highest lysozyme activity and the lowest superoxide dismutase(SOD)activity were found as feeding the C_(239.1) diet. According to broken-line analysis,the minimum dietary VC supplementation for maximum average gain rate and feed conversion rate of juvenile Chinese sturgeon was 108.5 mg/kg.In order to get the optimal VC concentration in liver,the VC supplementation in diet was(309.4 mg/kg) based on the broken-line analysis of liver VC concentration.In order to get the optimal VC concentration in muscle,the VC supplementation in diet was 273.3 mg/kg based on the broken-line analysis of muscle VC concentration. |
