Sridhar, Manpal and Sridhar, N and Robertson, P A W and Austin, B (2006) Role of Gut Probionts in Enhancing Growth and Disease Resistance in Rainbow Trout (Oncorhynchus mykiss, Walbaum) Fingerlings. Asian Fisheries Science , 19 (1). pp. 1-13.
Seven out of 34 isolates were selected as putative probionts. These were mixed with an equal volume of a lipid oralizer and incorporated into compounded feed pellets to achieve a dose of 5 x 107 bacterial cells•g-1 of fish food and fed to Rainbow trout Oncorhynchus mykiss fingerlings (average weight 23.69 g) for a period of 25 days. Superior growth (SGR) ranging between 0.32 to 0.57 (P<0.05) as compared to 0.05 of the control group was obtained in fingerlings maintained on the probiotic incorporated diets. A comparatively lower growth of 0.12 was obtained in group F5 but this was still higher than that of the animals maintained on a feed devoid of probiotics. Feed efficiencies ranging between 0.36 for group F5 to 1.03 for group F7 (P< 0.05) as compared to 0.08 of the control group were obtained in animals fed the probiotic feeds.
