Abstract

This study aims to investigate the effect of the different concentration of RABAL (yeast and lactic acid bacteria) probiotics on the survival, feed conversion, growth and intestinal cells changes of tiger shrimp Penaeus monodon Fab. larvae. This study used a Completely Randomized Design (CRD) method with 4 treatments and 4 replications. Tiger shrimp with average size of 0.02 g was randomly stocked in each container containing RABAL with concentration of 0 ppm (A/control), 75 ppm (B), 150 ppm (C), and 225 ppm (D) with frequency once a day for 30 days. Data were analysed using one way ANOVA. The result showed that the application of RABAL with different doses into the shrimp culture media significantly influences (P0.05) the growth and food conversion ratio of tiger shrimp feed but did not significantly affect (P 0.05) on the survival rate. The value of water quality parameters in this study were still at normal levels for tiger shrimp rearing. As conclusion, the application of probiotics RABAL with different concentrations have positive effect on the absolute weight, absolute length, specific growth rate, feed conversion ratio and intestinal villi surface area of tiger shrimp larvae, without adverse effect on the survival rate of tiger shrimp seed.

酵母和乳酸菌对虎对虾幼虾生长和肠道结构有改善作用。

本试验旨在研究不同浓度的酵母和乳酸菌(RABAL)益生菌对虎对虾(Penaeus monodon Fab)的存活、饲料转化率、生长和肠道细胞变化的影响。幼虫。本研究采用完全随机设计(CRD)方法，4个处理，4个重复。将平均大小为0.02 g的虎虾随机放入浓度为0 ppm (A/对照)、75 ppm (B)、150 ppm (C)和225 ppm (D)的RABAL容器中，每天1次，连续30 D。数据分析采用单因素方差分析。结果表明，在对虾培养基中添加不同剂量的RABAL对虎虾饲料的生长和食物转化率有显著影响(P0.05)，对虎虾成活率无显著影响(P0.05)。本研究的水质参数值仍处于虎虾养殖的正常水平。综上所述，施用不同浓度的RABAL益生菌对虎虾幼虫的绝对重量、绝对长度、特定生长率、饲料系数和肠绒毛表面积均有积极影响，对虎虾种子的成活率无不利影响。
