Effects of Dietary Pectin and Lactobacillus salivarius ATCC 11741 on Growth Performance, Immunocompetence, Gut Microbiota, Antioxidant Capacity, and Disease Resistance in Narrow-Clawed Crayfish, Postantacus leptodactylus

Table 2

Growth performance indices of narrow-clawed crayfish (Postantacus leptodactylus) fed with basal diet and supplemented with LS1 (L. salivarius,  CFU/g), LS2 (L. salivarius,  CFU/g), PE1 (Pectin, 5 g/kg), and PE2 (Pectin, 10 g/kg), LS1PE1 (L. salivarius,  CFU/g + Pectin, 5 g/kg) and LS2PE2 (L. salivarius,  CFU/g + Pectin, 10 g/kg) for 18 weeks.
