Fig. 4

Histological observation of myofibers in grass carp fed different levels of vitamin D. A Hematoxylin-eosin staining results in cross-sections of fish muscle (200×; n = 6); B Myofiber diameter; C Frequency of distribution (%) of myofibers in different diameter classes; D Transmission electron microscope image; E Sarcomere length of myofibers in fish supplemented with 15.2 (control) and 1,167.9 IU/kg vitamin D (n = 3). M line, Z disk, and sarcomere are shown to represent myofiber structure. Values are shown as means ± SD. Different letters above bars indicate significant differences (P < 0.05)
