عنوان مقاله [English]
A 12-week feeding trial was conducted to examine the effects of replacement of fish
meal with poultry by-product meal (PBM) in diets on growth, survival and blood parameters
of Acipenser stellatus in Khozestan province. Five experimental diets (isoenergetic and isonitrogenous pelleted diets) were formulated to contain graded levels of PBM at proportion
0, 25, 50, 75 and 100% (PBM0, PBM25, PBM50, PBM75, PBM100 respectively). The starry sturgeon were accidental distributed into groups of 5 Kg per m3 fish (1200±20 g) in 2×2×2 sediment pools. Each diet was fed to groups 3 times daily to apparent 1.5% of body weight. The highest levels of lactate dehydrogenase (LDH), alanine aminotransferase (ALT), alkaline phosphatase (ALP), glucose, cholesterol, triglyceride and albumin were 167.57±26.96 U/L, 3.25±0.44, respectively U/L, 391.63±77.44 U/L, 51.82±4.14 mg/dl, 54±8.32 dl, 354.68±56.16 mg/dl and 0.61±0.6 g/dl. The results of this study showed that diets containing poultry waste powder are an appropriate alternative to fish flour in fish diets because of a significant decrease in growth efficiency and food use following the use of this alternative, without The use of amine acid supplements was not observed in fish.
