配制5种饲料,速大肥(Stafac500)的添加量分别为0,20,40,60和80mg·kg-1,于室内水泥池(0.90m×0.60m×1.0m)分组进行实验,每池养凡纳滨对虾60尾,初始体重为0.22g,每组饲料3个平行,养殖时间8周。增重率(%)分别为1105±43,1115±33,1150±22,1192±53和1272±33;饲料系数分别为1.56±0.11,1.51±0.02,1.45±0.01,1.42±0.10和1.49±0.02。结果表明,投喂添加速大肥添加剂饲料的对虾生长性能优于对照组,对虾摄入不同剂量的速大肥对全虾的营养组成没有显著性差异。
Five kinds of feed were formulated. Stafac 500 was added into the indoor cement pool (0.90m × 0.60m × 1.0m) at 0, 20, 40, 60 and 80 mg · kg-1, respectively. Each pool The raising of Litopenaeus vannamei 60, the initial weight of 0.22g, 3 sets of feed each parallel, breeding time of 8 weeks. The weight gain rates (%) were 1105 ± 43, 1115 ± 33, 1150 ± 22, 1192 ± 53 and 1272 ± 33, respectively. The feed coefficients were 1.56 ± 0.11, 1.51 ± 0.02, 1.45 ± 0.01, 1.42 ± 0.10 and 1.49 ± 0.02. The results showed that the growth performance of shrimp fed diets supplemented with instant fertilizer was better than that of control. The fast fat manure with different doses of shrimp had no significant difference in the nutritional composition of whole shrimp.
