Effects of diets containing β‐glucan on survival, growth performance, haematological, immunity and biochemical parameters of rainbow trout (Oncorhynchus mykiss) fingerlings

This study aimed to investigate the effect of β‐glucan in rainbow trout's diet on survival, growth performance, haematological, immunity and biochemical parameters. Rainbow trout (Oncorhynchus mykiss) with an average weight of 6.33 ± 0.09 were stocked in 30 fibreglass tanks with a volume of 200...

Description
Summary:This study aimed to investigate the effect of β‐glucan in rainbow trout's diet on survival, growth performance, haematological, immunity and biochemical parameters. Rainbow trout (Oncorhynchus mykiss) with an average weight of 6.33 ± 0.09 were stocked in 30 fibreglass tanks with a volume of 200 L. Four treatments including control group (0%), 0.05%, 0.1% and 0.2% of β‐glucan were considered for 8 weeks. The results showed that the survival and growth performance of rainbow trout in the control group were at the lowest level and showed a significant difference (p
