|---|---|---|---|---|---|
| Fertility (%) | 87.85 ± 1.37 | 89.28 ± 2.95 | 84.29 ± 4.44 | 80.67 ± 0.79 | 86.67 ± 1.78 |
| Hatch of incubated eggs ( % ) | 76.31 ± 8.90 | 87.86 ± 2.15 | 81.91 ± 2.93 | 78.37 ± 0.49 | 76.42 ± 4.10 |
| Hatch of fertile egg ( % ) | 85.42 ± 2.20b | 96.0 ± 2.35a | 96.22 ± 2.19a | 95.03 ± 1.77a | 91.64 ± 1.48a |
| Embryonic mortality ( % ) | 12.59 ± 2.92a | 3.57 ± 2.14b | 4.81 ± 1.65b | 4.48 ± 1.50b | 7.14 ± 0.83ab |
Means ± SE within a row without a common superscript differ significantly (p < 0.05). T1, T2, T3, T4 and T5 represent the birds in the treatments supplemented with vitamin E at levels of zero (control), 30, 60, 120 and 240 mg kg-1, respectively.
