Abstract: (2301 Views) |
In this study, effect of replacement of fish meal by Poultry by product meal on growth index, biochemical and immune parameters of Huso huso with average weight 108.83±5. 9gr ± SD that reared in fiberglass tank (2000 lit) for 8weeks were investigated. Six test diets (contain 42% protein and 18.5 Mj kg-1 energy) were prepared. Fish meal substituted by poultry by product at 20% (PBM20), 40% (PBM40), 60% (PBM60), 80% (PBM80) and 100% (PBM100), respectively. In the end of nutrition period no significant difference were detected between Final weight (FW), Weight gain (WG) and Specific Growth Rate of fish fed (PBM0), (PBM20), (PBM40), (PBM60) and (PBM80) respectively )P>0.05(. Also, no significant difference by body protein were recorded between PBM00, PBM40, PBM60, PBM40 and PBM100, respectively) P>0.05(. but increasing of replacement led to decreasing of body lipid (P<0.05) .Catabolic enzymes (Aspartat amino transferase and Alanin Amino Transferase) were not affect by inclusion of poultry by product but plasma lysosyme was significantly higher than in PBM20compared to PBM 80 and PBM 100 (P<0.05). The result showed that high replacing of fish meal by poultry by product were not negative effect on growth index, biochemical and immune parameters of Huso huso in growth stage.
