A Natural Gas Fermentation Bacterial Meal (FeedKind<sup>®</sup>) as a Functional Alternative Ingredient for Fishmeal in Diet of Largemouth Bass, <i>Micropterus salmoides</i>
A 10-week growth study was conducted to evaluate the effect of a natural gas fermentation bacterial meal (FeedKind<sup>®</sup>, FK) as a fishmeal (FM) alternative in largemouth bass (<i>Micropterus salmoides</i>) (48.0 ± 0.03 g). Four isonitrogenous and isoenergetic diets wer...

| description | A 10-week growth study was conducted to evaluate the effect of a natural gas fermentation bacterial meal (FeedKind<sup>®</sup>, FK) as a fishmeal (FM) alternative in largemouth bass (<i>Micropterus salmoides</i>) (48.0 ± 0.03 g). Four isonitrogenous and isoenergetic diets were formulated including one commercial control (C, 42% FM) and three experimental diets with gradient FK of 3% (FK3, 29%FM), 6% (FK6, 26%FM) and 9% (FK9, 23%FM), respectively. FK-fed groups showed significantly higher SR than that of C group. The WGR and SGR of fish fed FK3 and FK6 were significantly higher than those of FK9, but not statistical different from the C group. FK-fed groups showed higher apparent digestibility coefficients of dry matter and nutrients. Further, FK-fed groups increased the ratio of SOD/MDA in the plasma and liver, and the upregulation of intestinal <i>Keap1</i> and downregulation of HIF1α was found in FK3. Furthermore, FK-fed groups showed higher microbial richness and diversity. Pearson correlation analysis found that antioxidant relevant biomarkers were negatively correlated with the relative abundance of certain potential beneficial bacteria. In conclusion, supplemented up to 3–6% FK replacing FM in a low FM diet of largemouth bass could increase growth, survival rate, antioxidant capacity, and improve gut microbiota. |
