| description | An eight-week feeding trial was performed to evaluate the effects of yeast hydrolysate (YH) supplementation in a low-fishmeal diet on the growth, immune responses, intestinal histology and disease resistance of whiteleg shrimp (<i>Litopenaeus vannamei</i>). Five experimental diets were produced by supplementing YH at 0 (CON), 0.5 (YH<sub>0.5</sub>), 1 (YH<sub>1</sub>), 2 (YH<sub>2</sub>) and 4 (YH<sub>4</sub>) % to a basal diet containing 10% fishmeal and compared with a positive control with 25% fishmeal (FM<sub>25</sub>). Shrimp with an initial average weight of 0.43 ± 0.005 g (mean ± SD) were stocked in 18 tanks and fed the experimental diets (38% protein and 8% lipid) four times a day. Results showed that shrimp fed the FM<sub>25</sub> diet exhibited significantly higher final body weight, weight gain, specific growth rate and protein efficiency ratio than those fed CON, YH<sub>0.5</sub>, YH<sub>1</sub> and YH<sub>2</sub> diets (<i>p</i> < 0.05). However, there were no significant differences between shrimp fed the YH<sub>4</sub> and FM<sub>25</sub> diets (<i>p</i> > 0.05). In addition, there were no significant differences in whole-body proximate composition, hemolymph biochemical parameters and non-specific immune responses among treatments. Intestinal villi length and muscular layer thickness of shrimp fed the YH<sub>4</sub> and FM<sub>25</sub> diets were significantly higher than the other groups. At the end of the bacterial (<i>Vibrio parahaemolyticus</i>) challenge test, shrimp fed YH<sub>4</sub> and FM<sub>25</sub> diets showed a significantly higher survival rate than those of shrimp fed CON, YH<sub>0.5</sub> and YH<sub>1</sub> (<i>p</i> < 0.05). These results suggest that supplementing 4% YH in diet containing 10% fishmeal could beneficially influence growth, intestinal morphology and disease resistance of whiteleg shrimp. |
