Abstract: (10086 Views) |
| In this study, feasibility of replacing fish meal with poultry by product was examined. Six test diet were
prepared based on anchovy fish meal (contain 45% protein and 20mj/ kg-1) and poultry by product
substituted at levels of 0, 20, 40, 60, 80 and 100%, respectively.180 fingerling Huso huso were stocked
(28.42±0.17gr average initial weight) in 18 fiberglass tanks (six treatments and eighteen replicate) and
were fed to satiation. At the end of 8 weeks feeding period, there were not significant differences between
the final weight, increase body weight and specific growth rate of fish fed to (control), (PBM20), (PBM40)
and (PBM60) (P>0.05), but growth performance were depressed significantly for Huso huso fed PBM80
and PBM100 compared with other treatments (P<0.05). Replacement of fish meal with poultry by product
at level of 60% had not negative effect on total protein (TP), Albumin (AL), Triglyceride (TG) and
Cholesterol (CL). Also, it was not found any significant increase or decrease in liver catabolic enzymes
(Aspartat amino transferase and Alanin Amino Transferase) for fish fed with PBM100 compared to other
treatments (P>0.05). Also, lysozyme were similar between PBM0, PBM20, PBM40 and PBM60 (P>0.05).
The result showed that up to 60% fish meal can be replaced with poultry by product with no adverse effect
on growth and feed conversion ratio, immune system, and liver enzymes and is a suitable source for
replacement with fish meal for feeding Huso huso in fingerling period. |
