Fig. 1

The length (L) and width (w) of proximal villi were measured and used to obtain length by width ratios for each villus.

Fig. 2

Relative gene expression of the group is represented as a fold change relative to the negative control group (fold change = 1). Values provided are mean fold change + S.E.M (standard error of the mean). Results of One-way ANOVA and LSD test are shown on graphs when significant. Significant differences (p < 0.05) between groups are represented by different letters.

Fig. 3

This figure presents two histological samples from the proximal intestines of zebrafish. Fig. A is a sample from the (−) Control group and Fig. B is from the Ala-Glu group. These images were obtained using LAS V4.4 software (Leica Camera, Wetzler, Germany, www.leica-microsystems.com).

Fig. 4

The concentration of indispensable free amino acids (μmol/g) in zebrafish muscle. Bars represent level (± std. dev) at 3 h after feeding. Line represents level at 24 h after feeding reflecting the baseline. Results of One-way ANOVA and LSD test are shown on graphs when significant. Significant differences (p < 0.05) between groups are represented by different letters.

Fig. 5

The concentration of dispensable free amino acids (μmol/g) in zebrafish muscle. Bars represent level (± std. dev) at 3 h after feeding. Line represents level at 24 h after feeding reflecting the baseline. Results of One-way ANOVA and LSD test are shown on graphs when significant. Significant differences (p < 0.05) between groups are represented by different letters.
