Table 5.

The muscle fiber diameter (DI, μm) and density (DE, n/mm²) of hybrid catfish fed diets containing graded levels of Leu (g kg^-1) for 8 weeks.

Leu	10.0	15.0	20.0	25.0	30.0	35.0	40.0
DI	28.85 ± 0.42^a	29.36 ± 0.92^a	34.35 ± 2.92^ab	38.48 ± 1.85^b	33.31 ± 1.64^ab	29.74 ± 0.31^a	28.63 ± 0.77^a
DE	64.00 ± 1.79^a	79.4 ± 3.97^b	88.4 ± 4.53^bc	103.5 ± 7.58^c	90.6 ± 2.5^bc	95.4 ± 1.81^bc	87 ± 6.82^bc

Values are means ± SEM (n = 3, 18 fish per treatment). Mean values with different superscripts in the same row are significantly different (P < 0.05).
