| 摘 要： | 提出以稳定态的ＬＡＰＰ代替一般维生素Ｃ添加在配合饲料中饲喂对虾，指出：在１００ｇ饲料中含ＬＡＰＰ４００ｍｇ时，其体长增长率和体重增重率最高，存活率最佳．饲料中ＬＡＰＰ浓度大小影响对虾的蜕壳频率和蜕壳周期，当饲料中ＬＡＰＰ缺乏时，对虾的蜕壳频率降低，蜕壳周期延长；过量的ＬＡＰＰ也会使对虾的蜕壳频率相对降低，但比缺乏或不足的要高。维生素Ｃ在对虾肝胰脏中的积累以ＬＡＰＰ含量４００ｍｇ／１００ｇ饲料组为最高。

| Abstract: | Vitamin C is an essential nutrient in the diet of prawn, Penaeus chinensis. In the present study, L-ascorbic acid polyphosphate (LAPP) was served as a stable vitamin C source in the purified diets. The results obtained from the study are summarized as follows: The best growth and the high survival were observed in the group maintained on 400mg LAPP per 100g dry diet. The dietary LAPP levels had apparent effects on the molty frequency and the molty cycle of the test prawn. The prawn fed on a LAPP-deficient diet showed the smallest molty frequency and the longest molty cycle. Also,the prawn maintained on a diet with a high LAPP level exhibited relatively smaller molty frequency. The optimum level of the dietary LAPP was found to be approximately 400mg LAPP per 100g dry diet on the basis of the growth, survival, and the molty frequency of the test prawn. The prawn fed 400mg LAPP per 100g dry diet had the highest content of vitamin C in hepatopancreas. |
