This study was carried out to investigate alternative instead of corn gluten meal in diets and the effects of this substitution on blood biochemical and hematological parameters of common carp juvenile. Juvenile's carp with an average 11.5 ± 0.5g, 9 ± 1cm weight and length respectively, were fed with experimental diets for 8 weeks. Diets with 31% crude protein and 3100 kcal kg-1 raw energy alternative levels of 150, 270 and 490 (gr kg-1) and a control diet without corn gluten was made. At the end of the experiment, blood biochemical parameters, including glucose, cholesterol, triglycerides, and hemoglobin, hematocrit, white blood cells (WBC) and red blood cells (RBC) in juveniles fed the experimental diets compared with the control group showed a significant difference (P0.05). Also with replacement value of corn gluten in experimental diets, it was concluded that growth and nutritional factors treatments compared with control group significantly decreased (P

The objective of this study was to evaluate the performance of nutritional programming on growth and hematological indices of sterlet sturgeon (Acipenser ruthenus) during the larval stage by partial replacement of fish meal (FM) with soybean meal (S). Sterlet sturgeon with initial mean weight of 0.32 ± 0.01 g were randomly distributed into twelve circular concrete tanks (260 fish per each tank) and fed four experimental diets with substitution levels of 0 (control/FM), 15% (S15), 30% (S30) and 45% (S45) of fish meal with soybean meal during three phases in three replicates. In phase 1 (programming), fish were fed four different diets for 28 days. All the groups were then fed with FM during phases 2 (intermediate) and S45 at phase 3 (challenge) for 28 days. At the end of each phase, growth indices were measured. Hematological indices including red blood cell, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were assessed at the end of the challenge phase. The growth performance was not significantly different in either phases 1 or 2 (P > 0.05); however, final weight, weight gain, specific growth rate, and average daily growth were significantly higher in S45 than FM during phase 3 (P < 0.05). Moreover, no significant difference was indicated among the groups in hematological indices (P > 0.05). According to the obtained results, early nutritional programming could effectively enhance the adaptation of sterlet sturgeon to plant-based protein later in life.
