| Popis: | This study aimed to evaluate the use of protein hydrolysate of poultry by-product and swine liver in the diet of Litopenaeus vannamei and its effect on the intestinal microbiota and on the enzymatic activity of the hepatopancreas. Shrimp (10.94 ± 0.90 g) were fed with diets containing 0%, 25%, 50%, 75% and 100% of replacement of salmon by-product meal by protein hydrolysate, in triplicate. The hepatopancreas enzymatic activity and composition of intestinal microbiota was studied. It was observed that the protein hydrolysate in the diet changed the enzymatic activity of the shrimp when compared to the control group (p < 0.05). Amylase activity increases directly with the percent of protein replacement in the diet. Metagenomic analysis revealed change in the gut biome of the shrimps. The increasing levels of protein replacement provided greater richness in the 75% and 100% treatments, were mainly related to changes in the abundances in the families Rhodobacteraceae and Flavobacteriaceae. A reduction in the abundance of the Vibrionaceae family was observed with the inclusion of protein hydrolysate in the diet. These results indicate that the protein hydrolysate demonstrated beneficial changes when added at concentrations of 25% in the diet of L. vannamei. |
