Table 4.

Percentages of PepT1-expressing region lengths, relative to total villi lengths of control and in-ovo feeding (IOF) -treated chicks (%).^1,2

Item	Treatment	PepT1+ region
E 17	Pre-IOF	94.4 ± 1.7a
E 19	Control (non-injected)	85.8 ± 2.4a
	IOF-NaCl	72.5 ± 1.9b
	IOF-Leu	64.8 ± 2.3b
	IOF-Gln	90.6 ± 1.5a

PepT1 = peptide transporter 1; E 17 = embryonic d 17; E 19 = embryonic d 19.

^{a, b} Different uppercase letters mark significant differences by Tukey–Kramer HSD, P < 0.05.

¹Percentage of region length = 100 × [PepT1+Segment length (μm)/Total villus length (μm)].

²Values are means ± SEM.
