Impact of Germinated Wheat Greens and Seeds on Fish Health and Performance

This study investigated the impact of dietary supplementation with different portions of germinated wheat on the growth performance, health status, and physiological parameters of common carp (Cyprinus carpio L.). A six-week feeding trial was conducted using 128 fish distributed into five treatment groups: a control group (Group 1), diets supplemented with 5g or 10g of germinated wheat green parts (Groups 2 and 3), and diets supplemented with 5g or 10g of whole germinated wheat seeds (Groups 4 and 5) .The results demonstrated that growth performance was significantly influenced by the supplement type; Group 5 (10g seeds) exhibited the highest weight gain (8.35 g) and relative growth rate (38.85%), while Group 3 (10g green part) showed the poorest weight gain (0.76 g) and the highest Feed Conversion Ratio (FCR) of 16.46.  Biological analysis revealed that Group 3 had significantly higher kidneysomatic and intestine length indices, suggesting physiological adaptations to the green part supplement. Hematological profiles showed that Group 5 achieved the highest hemoglobin levels (15.47 g/dL), whereas Group 3 had significantly lower hematocrit and platelet counts. Biochemical analysis indicated a significant reduction in serum glucose levels in Groups 4 and 5 compared to the control. Furthermore, liver health was positively affected, as ALT and AST enzyme levels were significantly lower in all germinated wheat groups, indicating a potential hepatoprotective effect. While total protein was highest in Group 5, lipid profiles remained stable across all treatments. In conclusion, supplementation with 10g of whole germinated wheat seeds optimizes growth and physiological health in common carp, whereas high concentrations of the green portion may negatively impact feed efficiency and development.
