Table 2.

The eggshell translucency of different hen strains in the late-phase laying cycle.

Strain	Week	Number of eggs/hen		Score of shell translucency
		Translucent	Opaque	Translucent	Opaque
Rhode Island Red-White (N = 116)	67	2.46 ± 0.90	2.61 ± 0.67	3.34 ± 0.46^ax	1.93 ± 0.40^z
	75	2.60 ± 0.93	2.81 ± 0.60	3.21 ± 0.71^abx	2.21 ± 0.57^z
	79	2.16 ± 1.14	2.33 ± 0.91	3.12 ± 0.66^abx	2.58 ± 0.96^z
	83	2.22 ± 1.31	2.19 ± 1.29	2.86 ± 0.72^bx	2.08 ± 0.75^z
Dwarf Layer-White (N = 116)	67	2.41 ± 0.84	2.69 ± 0.55	3.19 ± 0.51^x	1.92 ± 0.32^az
	75	2.78 ± 0.61	2.73 ± 0.72	3.04 ± 0.75^x	2.57 ± 0.71^bz
	79	2.16 ± 1.17	2.46 ± 0.99	3.07 ± 0.74^x	2.43 ± 0.64^bz

^{a, b}Within each column, there were statistical differences in the score of shell translucency among the same strain at different weeks of age. ^{x, z}Within each row, there are statistical differences in the score of shell translucency among the same strain for translucent and opaque groups per age week. The score of shell translucency was per a 1–4 scoring system (score 4 is most translucent). All values are mean ± standard deviation.
