| Abstract | ||
| A total of 1050 Sudany duck eggs were used in this experiment. Eggs were divided randomly into 7 treatments with three replicates each to study the influence of iron in different forms In-Ovo injection on hatchability traits and post- hatch performance of Sudany ducklings. The first group (G1) was served as control, (without injection); the eggs in 2nd (G2) and 3rd (G3) groups injected with 0.1 and 0.2 ml saline solution contains 10 and 20 ppm Nano organic iron. The eggs in 4th and 5th groups were injected with 0.1 and 0.2 ml saline solution contains 10 and 20 ppm Nano inorganic iron. The eggs in 6th group was injected with 0.1 saline solution contain 10 µg organic iron, while the eggs in 7th group was injected with 0.1 ml saline solution contain 10 µg inorganic iron. The results indicated that, no significant differences of different forms of iron on hatchability traits. At hatch, ducklings hatched from eggs in groups G2 and G3 recorded significantly high values of A/G ratio, MDA and HDL. Ducklings hatched from eggs injected with different forms of iron had significantly higher values of plasma IGF1 and T3 hormone and lower values of LDL than the control group. Ducklings hatched from eggs in group (G6) resulted in significantly higher values of plasma RBCs, HB and heterophiles than the control group. Also, all treated groups had high values of plasma WBCs compared to control except G7. Duckling in G2,G5 and G6 gave high LBW at 12 and 16 weeks of age . Also, duckling in (G2) recorded significantly high values of BWG throughout the trial period. These results suggest that, pre incubation In-Ovo injection with different forms of iron improved some blood plasma constituents of chicks at hatch and enhance post-hatch productive performance of Sudany ducklings from hatching until 16 weeks of age | ||
