The relative abundance of (A) testosterone, (B) androstenedione, (C) etiocholanolone, (D) progesterone, (E) pregnonelone, and (F) 11β-hydroxy-progesterone/11-deoxycorticosterone in the yolk of commercial male and female meat-type chickens at embryonic day (ED) 0 (n = 10), ED 5 (n = 10), ED 15 (n = 40), and hatch (n = 40). Embryos were exposed to a CON or CORT solution via the chorioallantoic membrane at ED 11. Values are mean ± SEM. Quantified normalized area refers to the integrals of the area under the chromatographic peak. * Indicates statistical (P < 0.05) significance.
