Changes of Plasma Growth Hormone, Insulin-Like Growth Factors-I, Thyroid Hormones, and Testosterone Concentrations in Embryos and Broiler Chickens Incubated under Monochromatic Green Light

Figures & data

Figure 1. Plasma growth hormone in late embryonic (E15, E17 and E19 d of age) and posthatched chickens (H1, H3, H5, H7, H21, H35 and H42 d of age) incubated under green light or dark condition. Values are presented as mean±standard error; n=6 (not sexed) from 15 to 19 d of incubation; n=6 (males) from 1 to 42 d posthatch. Asterisks indicate a significant difference among treatments at the same age (P<0.05).

Figure 2. Plasma insulin-like growth factor-I in late embryonic (E15, E17 and E19 d of age) and posthatched chickens (H1, H3, H5, H7, H21, H35 and H42 d of age) incubated under green light or dark condition. Values are presented as mean±standard error; n=6 (not sexed) from 15 to 19 d of incubation; n=6 (males) from 1 to 42 d posthatch. Asterisks indicate a significant difference among treatments at the same age (P<0.05).

Figure 3. Plasma thyroxine in late embryonic (E15, E17 and E19 d of age) and posthatched chickens (H1, H3, H5, H7, H21, H35 and H42 d of age) incubated under green light or dark condition. Values are presented as mean±standard error; n=6 (not sexed) from 15 to 19 d of incubation; n=6 (males) from 1 to 42 d posthatch.

Figure 4. Plasma triiodothyronine in late embryonic (E15, E17 and E19 d of age) and posthatched chickens (H1, H3, H5, H7, H21, H35 and H42 d of age) incubated under green light or dark condition. Values are presented as mean±standard error; n=6 (not sexed) from 15 to 19 d of incubation; n=6 (males) from 1 to 42 d posthatch.

Figure 5. Plasma testosterone in late embryonic (E15, E17 and E19 d of age) and posthatched chickens (H1, H3, H5, H7, H21, H35 and H42 d of age) incubated under green light or dark condition. Values are presented as mean±standard error; n=6 (not sexed) from 15 to 19 d of incubation; n=6 (males) from 1 to 42 d posthatch.
