摘要
为了研究饲料中添加不同剂型维生素C对锦鲤生长性能及其组织中维生素C含量的影响,按饲料中维生素C有效含量为50、100、150、200 mg/kg的剂量分别添加维生素C多聚磷酸酯和包膜维生素C,进行为期60 d的锦鲤饲养试验。结果表明,当分别在饲料中添加维生素C多聚磷酸酯100～200 mg/kg和包膜维生素C 150～200 mg/kg (均以有效维生素C含量计)时,锦鲤生长速度较快,成活率较高,尤其是有效维生素C含量分别在150 mg/kg和200 mg/kg时,锦鲤肌肉和肝脏组织维生素C含量最高,且肝脏的维生素C含量高于肌肉;饲料中添加维生素C多聚磷酸酯对锦鲤的生长促进效果优于添加包膜维生素C。
To clarify the effects of vitamin C supplement in diet from different sources on the growth performance and tissue vitamin C content of Cyprinus carpio ,four levels of coated-ascorbic acid(CAA)or ascorbic acid polyphosphate(LAPP)(50,100,150,and 200 mg/kg,vitamin C effective content in diet)were used.The experiment period was 60 d.The results showed that the optimal vitamin C effective content of LAPP and CAA requirements were 100~200 mg/kg diet and 150~200 mg/kg diet in koi juveniles,respectively.The fish groups of 150 mg(LAPP)/kg diet and 200 mg(CAA)/kg diet had the maximal vitamin C content in muscle and liver.And the liver vitamin C concentrations were higher than that of the muscle vitamin C concentrations.In conclusion,LAPP had advantage over CAA in promoting the growth of Cyprinus carpio.
