Effects of dietary alphamion probiotic on growth, hematological indices and proximate composition of Huso huso

Abstract

This experiment was conducted to examine the effect of dietary alphamion probiotic on growth, hematological indices and body composition of Huso huso fingerlings. A basal diet supplemented with 0 (control), 0.5, 1, 1.5 and 2 percent probiotic to formulate five experimental diets. Each diet was randomly allocated to triplicate groups of fish with initial average weight of approximately 192±3.2 g. After 8 weeks of feeding trial, fish fed diets with probiotic showed the highest final weight and SGR, and lowest in fish fed the control diet (P < 0.05). The feed conversion ratio (FCR) was better when the fish were fed diet with 2 percent prebiotic. There were significant differences in cortisol and lysozyme in fish fed by dietary probiotic (P < 0.05). At the end of feeding trial, the fish fed 1% diet showed higher whole body protein. The fish fed 2% diet exhibited lower levels of lipid and ash. The results suggest that administration of dietary alphamion probiotic at 1-2 percent exerted positive effects on growth, hematological indices and body composition in Huso huso.
