用酪蛋白作为蛋白源、制成含肌醇及含氯化胆碱的饲料,对中国对虾进行饲喂试验,通过存活率等指标探讨了中国对虾对肌醇和氯化胆碱的营养需要。结果表明,含肌醇0.4％的饲料饲喂的对虾,有三项指标均为最佳,其中蜕壳率随饲料中肌醇含量的增加而上升,用含氯化胆碱0.4％和0.6％的饲料饲喂的对虾,存活率都为最高,增重率、增长率及蜕壳率以含氯化胆碱0.4％的饲料饲喂的对虾最高,体内含量随饲料中氯化胆碱含量的增加而上升。在本实验条件下,中国对虾饲料中肌醇和氯化胆碱的适宜添加量均为0.4％。还讨论了肌醇及氯化胆碱的缺乏与对虾死亡的关系。
Using casein as a protein source, a feed containing inositol and choline chloride was prepared to feed Chinese shrimp. The nutritional requirements of Chinese shrimp for inositol and choline chloride were discussed through the indexes of survival rate and the like. The results showed that 0.4% of inositol diet fed shrimp, the three indicators are the best, wherein the molting rate with the feed inositol content increased, with 0.4% and 0.6% of choline chloride The feedstuff prawn had the highest survival rate, the highest weight gain rate, the growth rate and the exfoliation rate. The shrimp fed with 0.4% choline chloride had the highest body feeding, and the content in vivo increased with the increase of choline chloride content And rise. Under the experimental conditions, the appropriate amount of inositol and choline chloride in shrimp feed was 0.4%. The relationship between the absence of inositol and choline chloride and the death of shrimp was also discussed.
