Abstract

ABSTRACT This study investigated the effects of dietary mixed and sprayed of Bacillus subtilis subsp. inaquosorum IS02 (B.s.i. IS02) on growth performance and digestive enzyme activity of whiteleg shrimp. Three different dosages of B.s.i. IS02 were applied via two application methods: mixed with (TM) and sprayed on (TS) feed containing 108 (TM1 and TS1), 107 (TM2 and TS2), 106 (TM3 and TS3) CFU Kg−1. Compared to control groups, growth performance was significantly higher in treated shrimp. There was a significant difference in survival rate between TM1 (94.44 ± 1.57%) and TM2 (87.78 ± 1.92%) compared to the other diets. Furthermore, the activity of digestive enzymes was significantly higher in TS1. Overall, it can be concluded that spraying B.s.i. IS02 at the dosage of 107 or 108 CFU kg−1 on feed can be a useful method in the farm; also, mixing at the dose of 108 CFU kg−1 may prove effective in feed factories.

饲料中混合和喷洒益生菌可改善白对虾幼虾的生长性能和消化酶(凡纳滨对虾，Boone, 1931)

摘要本试验研究了饲粮中混合和喷洒枯草芽孢杆菌的效果。inaquosorum IS02 (b.s.i. IS02)对白对虾生长性能和消化酶活性的影响。采用两种不同剂量的施用方法，分别与(TM)混合和喷洒在含有108 (TM1和TS1)、107 (TM2和TS2)、106 (TM3和TS3) CFU Kg−1的(TS)饲料上。与对照组相比，处理对虾的生长性能显著提高。与其他饲粮相比，TM1(94.44±1.57%)和TM2(87.78±1.92%)的成活率差异有统计学意义。此外，TS1的消化酶活性显著提高。综上所述，在饲料中喷洒107或108 CFU kg - 1 b.s.i. IS02是一种有效的方法;此外，在饲料工厂中，以108 CFU kg - 1的剂量混合可能是有效的。
