ND: No development; PD: Positive development; BWE: Blastoderm without embryo; D1–5: Died on day 1 to 5 of incubation; D6–10: Died on day 6 to 10 of incubation; D11–15: Died on day 11 to 15 of incubation; D16–20: Died on day 16 to 20 of incubation; D21–27: Died on day 21 to 27 of incubation; AE: Abnormal embryo; Perinatal death: Drowned in the egg; Hatched: Hatched chicklings; Σ: All incubated eggs. Pairwise comparisons (Chi-squared tests) between pairs of proportions were performed to compare the four experimental groups in every column (p < 005 was considered significant).
