Effects of Artemisia argyi leaf water extract (AWE) on growth performance, muscle quality, intestinal microbial, and metabolomics of common carp (Cyprinus carpio)
This study aimed to investigate the impact of Artemisia argyi leaf water extract (AWE) on the growth and metabolism of common carp (Cyprinus carpio). Over a period of 56 days, varying concentrations of AWE—0 % (A0), 0.1 % (A1), 0.2 % (A2), and 0.4 % (A3)—were incorporated into the feed for carp. The...

| Summary: | This study aimed to investigate the impact of Artemisia argyi leaf water extract (AWE) on the growth and metabolism of common carp (Cyprinus carpio). Over a period of 56 days, varying concentrations of AWE—0 % (A0), 0.1 % (A1), 0.2 % (A2), and 0.4 % (A3)—were incorporated into the feed for carp. The effects of AWE supplementation were assessed through various parameters including growth performance, flesh quality, biochemical indices, tissue structure, intestinal microbiota composition, and metabolomics analysis. Notably, treatment with A1 significantly enhanced the growth performance of carp while increasing body fat content and reducing protein levels (p < 0.05). Furthermore, A1 led to a significant increase in intestinal villi length (p < 0.05) and a reduction in liver fat deposition levels. Additionally, A1 concentration elevated protease activity within the intestine, with Trypsin exhibiting markedly higher activity compared to other groups (p < 0.05). The antioxidant capacity was also significantly improved across experimental groups (p < 0.05). Analysis of intestinal microbiota revealed that Cetobacterium and Aeromonas may play crucial roles as genus-level microorganisms in modulating metabolic processes associated with AWE in carp intestines. Metabolomic analyses indicated that pathways related to valine, leucine, and isoleucine biosynthesis were among those most profoundly affected by AWE supplementation. This experiment demonstrates that AWE exerts a growth-promoting effect on common carp at an optimal concentration near 0.1 %. These findings enhance our understanding of the potential applications of AWE in aquaculture practices and provide a theoretical basis for its utilization. |
