摘要
An 8-week growth trial was undertaken to evaluate the effects of dietary lysine (Lys) levels on growth, feed utilization and related gene expression of juvenile hybrid grouper (Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂). Six isonitrogenous (53.5% of dry matter) and isolipidic (7% of dry matter) were formulated to contain 1.74%, 2.18%, 2.94%, 3.28%, 3.66% and 3.99% dietary Lys levels. Triplicate groups of 15 fish (average initial body weight: 11.44 ± 0.07 g) were fed each experimental diet to apparent satiation by hand twice daily (08:00 h and 16:30 h). Results showed that weight gain % (WG%) were significantly (P
