摘要: 为研究青鱼鱼种饲料中不同剂型维生素C的适宜添加量,采用600尾平均体重为2.5 g的青鱼鱼种,在精制饲料(对照组)中添加不同水平的包膜VC(VC添加量分别为100mg/kg,200mg/kg,400mg/kg,600mg/kg,800mg/kg)和VC-2-多聚磷酸酯(VC添加量分别为100mg/kg,200mg/kg,400mg/kg,600mg/kg),饲养青鱼鱼种5周。结果发现,当饲料中缺乏VC时,青鱼鱼种表现出生长缓慢,脊柱弯曲,体表出血等症状,随饲料中VC添加量的增加,青鱼鱼种的增重率和肝脏VC含量也增加,当饲料中VC添加量分别达到200mg/kg(VC-2-多聚磷酸酯)和400mg/kg(包膜VC)以上时,青鱼鱼种的增重率和肝脏VC含量基本达到稳定。表明青鱼鱼种饲料中VC的适宜添加量为200mg/kg(VC-2-多聚磷酸酯)或400mg/kg(包膜VC)。

Abstract: To determine the proper addition of different style VC, 600 fingerling black carp with an average weight 2.5 g, were fed purified diet without(control) or with coated ascorbic acid(CAA, 100, 200, 400, 600, 800 mg VC/kg diet), L-ascorbyl-2-polyphosphate(LAPP, 100, 200, 400, 600 mg VC/kg diet) for five weeks. Retarded growth, hyperemia and spinal deformities were observed when fingerling black carp were fed without supplemental VC. With the increase of supplemental VC in diets, growth rate and VC content of liver also increased, and kept constant until supplemental VC in diets were more than 400 mg/kg(CAA) or 200 mg/kg(LAPP). The results above show that the addition of VC in diets of fingerling black carp is 200 mg/kg(LAPP) or 400 mg/kg(CAA).
