| 摘 要： | 对幼建鲤维生素C需要量的确定标识进行了研究 ,选择初始体重为 12g左右 (P >0 0 5 )的健康幼建鲤 5 76尾 ,平均分成 6组 ,每组 96尾 ,每组设 3个重复 ,每个重复 32尾 ,分别饲喂含维生素C为 10mg/kg、2 5mg/kg、4 5mg/kg、6 0mg/kg、90mg/kg、12 0mg/kg的半纯合饵料 70d。结果表明 :增重、状态系数、肝胰重与饵料维生素C水平呈极显著二次回归关系 (P <0 0 1) ,饵料系数、体长和后肾维生素C含量与饵料维生素C水平呈显著的二次相关(P <0 0 5 ) ,当饵料维生素C分别为 6 6 6 0mg/kg、6 1 74mg/kg、6 1 6 4mg/kg、6 9 5 1mg/kg、6 0 5 6mg/kg和 10 3 73mg/kg时 ,分别达到最佳增重、最佳状态系数、最大肝胰重、最低饵料系数或最佳饲料利用率、最佳体长和最大后肾维生素C含量

| Abstract: | The required index of vitamin C (VC) for juvenile jian carp were studied in this lecture. 576 healthy juvenile jian carp were divided into six groups, with feeding the semi-purified diets containing 10?mg/kg, 25?mg/kg, 45?mg/kg, 60?mg/kg, 90?mg/kg, 120?mg/kg of VC respectively for 70 days. The results show that the VC in diets significantly influnce feed intake, body length, body weight, weight gain/feed intake, hepatopancrease weight and condition factor (P<0.01), and significantly influence VC contend in post kidney (P<0.05) too, The significant quadratic regression relationship between weight gain, weight gain/feed intake, condition factor, body length, VC content in post kidney, hepatopancrease weight and the dietary VC levels is observed (P<0.05). With diet containing VC 66.60?mg/kg, 69.51?mg/kg, 60.56?mg/kg, 61.74?mg/kg, 61.64?mg/kg and 103.73?mg/kg, the weight gain, feed utilization, body length, condition factor, hepatopancrease weight and VC content in post kidney are the best. |
