Abstract

This study aims to analyze the performance of the Lactobacillus sp., in the digestive track of the white shrimp after being given various prebiotic in the feed. Test animals used in this study was white shrimp juvenile Litopenaeus vannamei, measured the weight of 1.84±0.23 g/individual with a stocking density of 10 shrimp/container, cultured for 30 days in a tank measuring 50x45x45 cm3 of 12 units, used the recirculation systems and filled 50 L seawater with salinity of 15 ppt. The treatments were four types of feed that is formulated with several of prebiotics i.e. A (without prebiotic), B (lotus seeds), C (sweet potatoes) and D (copra). In These four types of treatments has been added with Lactobacillus sp. with a population density of 1.5x109 CFU/ml. The result showed that the effect of feeding with various prebiotic on the performance of Lactobacillus bacteria population (1.4x104–1.2x105 CFU/ml) were not significantly different, but it was significantly different to the enzyme α-amylase activity, (0.2558 IU/mL/minute), digestibility of carbohydrates (91.89%). The best resulted is feed added with prebiotic copra, while the fat digestibility (83.93%) that resulted in the feed without prebiotic showed the lowest result.
