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>0.05)的健康幼建鲤576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、25mg/kg、45mg/kg、60mg/kg、90mg/kg、120mg/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<0.01),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<0.05),当饵料维生素C分别为66.60mg/kg、61.74mg/kg、61.64mg/kg、69.51mg/kg、60.56mg/kg和103.73mg/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.
