Metabolomics to elucidate the effects of novel sustainable feed additives in the feed of farmed salmon (HoloFood Trial D - fermented seaweed open water-dose response)
Ontology highlight
ABSTRACT: Testing the effect of seaweed as a novel cost-efficient feed source for Atlantic salmon feed. Fermentation of novel raw materials for fish feed is a new practice with little prior experience of direct relevance to aquaculture and fish farming. In Trial D, an alternative marine compound is included in the feed, which is based on seaweed. HoloFood Trial D - fermented seaweed open water-dose response is reported in the current study MTBLS6733. HoloFood Trial A - seaweed-dose response is reported in MTBLS4381. HoloFood Trial B - blue mussel-dose response is reported in MTBLS4382. HoloFood Trial C - blue mussel ensilage-dose response is reported in MTBLS4384. HoloFood Trial 1/2/3 is reported in MTBLS6988. Linked cross omic data sets: Nucleic acid data associated with this study are available in the European Nucleotide Archive (ENA): accession number PRJEB43192. Metagenomic data associated with this study are available from MGnify under the Super Study 'holofood'.

Project description:<p>Chicken farming is critical for future food security, yet there is still a need for improving animal welfare and optimised feeding strategies. HoloFood will explore the interaction and impact of the microbiome together with the host (animal) in response to different feeding strategies already implemented commercially. Chicken farming has recently made huge efforts towards healthy, natural food production without using chemicals or antibiotics in food systems. As such natural alternatives, such as prebiotic and probiotic additives to chicken feed, have been a huge improvement. Nonetheless, the full impact of these natural alternatives and the variation in chicken growth is still poorly understood. HoloFood aims to investigate the effect and interplay between the host (chicken) - microbiome in response to different dietary additives.</p><p><br></p><p><strong>HoloFood Trial 1/2/3</strong> is reported in the current study <a href='https://www.ebi.ac.uk/metabolights/MTBLS6988' rel='noopener noreferrer' target='_blank'><strong>MTBLS6988</strong></a>.</p><p><strong>HoloFood Trial A - seaweed-dose response</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS4381' rel='noopener noreferrer' target='_blank'><strong>MTBLS4381</strong></a>.</p><p><strong>HoloFood Trial B - blue mussel-dose response</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS4382' rel='noopener noreferrer' target='_blank'><strong>MTBLS4382</strong></a>.</p><p><strong>HoloFood Trial C - blue mussel ensilage-dose response</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS4384' rel='noopener noreferrer' target='_blank'><strong>MTBLS4384</strong></a>.</p><p><strong>HoloFood Trial D - fermented seaweed open water-dose</strong> response is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS6733' rel='noopener noreferrer' target='_blank'><strong>MTBLS6733</strong></a>.</p><p><br></p><p><strong>Linked cross omic data sets:</strong></p><p>Nucleic acid data associated with this study are available in the European Nucleotide Archive (ENA): accession number <a href='https://www.ebi.ac.uk/ena/browser/view/PRJEB43192' rel='noopener noreferrer' target='_blank'>PRJEB43192</a>.</p><p>Metagenomic data associated with this study are available from MGnify under the Super Study '<a href='https://www.ebi.ac.uk/metagenomics/super-studies/holofood' rel='noopener noreferrer' target='_blank'>holofood</a>'.</p>

Project description:<p>Testing the effect of blue mussel ensilage as a novel cost-efficient protein feed source for Atlantic salmon feed. Fermentation of novel raw materials for fish feed is a new practice with little prior experience of direct relevance to aquaculture and fish farming. In Trial C, alternative processing of the raw blue mussel meat was tested where the protein was ensilaged before use instead of processed into a dry meal. By using this preservation process, a significant part of small peptides and free amino acids is generated. This trial aimed to examine whether the provision of better protein utilisation and a different microbiome in the gut of the fish can lead to a satisfactory utilisation of this ensilaged protein source by salmon. Earlier published results have shown that ensilaged fish protein provides better protein utilization and growth in Atlantic salmon. It is our assumption that the nutrient value of this product, therefore, is different compared to the more traditional protein meal tested in Trial B. It may also influence the microbiota in the gut differently based on the same arguments. The results from trial C will be very important as this ensilage-based treatment has not yet been used at a routine level, so any new information on its effect on fish health and growth will be highly useful to the aquaculture industry at large.</p><p><br></p><p><strong>HoloFood Trial C - blue mussel ensilage-dose response</strong> is reported in the current study <a href='https://www.ebi.ac.uk/metabolights/MTBLS4384' rel='noopener noreferrer' target='_blank'><strong>MTBLS4384</strong></a>.</p><p><strong>HoloFood Trial A - seaweed-dose response</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS4381' rel='noopener noreferrer' target='_blank'><strong>MTBLS4381</strong></a>.</p><p><strong>HoloFood Trial B - blue mussel-dose response</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS4382' rel='noopener noreferrer' target='_blank'><strong>MTBLS4382</strong></a>.</p><p><strong>HoloFood Trial D - fermented seaweed open water-dose response</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS6733' rel='noopener noreferrer' target='_blank'><strong>MTBLS6733</strong></a>.</p><p><strong>HoloFood Trial 1/2/3</strong> is reported in <a href='https://www.ebi.ac.uk/metabolights/MTBLS6988' rel='noopener noreferrer' target='_blank'><strong>MTBLS6988</strong></a>.</p><p><br></p><p><strong>Linked cross omic data sets:</strong></p><p>Nucleic acid data associated with this study are available in the European Nucleotide Archive (ENA): accession number <a href='https://www.ebi.ac.uk/ena/browser/view/PRJEB43192' rel='noopener noreferrer' target='_blank'>PRJEB43192</a>.</p><p>Metagenomic data associated with this study are available from MGnify under the Super Study '<a href='https://www.ebi.ac.uk/metagenomics/super-studies/holofood' rel='noopener noreferrer' target='_blank'>holofood</a>'.</p>

We also used LipidCreator's relative fragment intensity prediction model to generate a custom spectral library for the light and heavy mediators.

Project description:<p>The biogeography of tropical Andean plants and the effects of altitudinal barriers as evolutionary constraints have been the focus of great debate. Although genetic markers have provided evidence for the geographic isolation of Andean-endemic groups, even highly variable molecular markers commonly used to assess biogeography do not have the resolving power needed for a fine geographic discrimination in some Andean taxa. We present a metabolomics approach based on ultrahigh-performance liquid chromatography-mass spectrometry combined with multivariate statistical methods and machine learning algorithms of multiple species and populations of Espeletiinae (Asteraceae) to provide metabolomic evidence for biogeographic segregation in this Andean-endemic subtribe. Our approach allows the discrimination of Espeletiinae taxa at different geographic scales with characteristic metabolic fingerprints related to their country of origin on a global scale, to their páramo massifs on a regional scale and to their páramo complexes on a local scale, revealing inter- and intraspecific metabolic variations. Our results, together with previous studies, suggest that Andean geography and Pleistocene glacial cycles not only shaped the evolutionary history of Espeletiinae but also its metabolic fingerprints, demonstrating the potential of metabolomics for understanding biogeographic patterns in recently diversified plant groups where genetic divergence is still at an early stage.</p><p><br></p><p><strong>Intraspecific chemical variability assay</strong> protocols and data are reported in the current study <a href='https://www.ebi.ac.uk/metabolights/MTBLS943' rel='noopener noreferrer' target='_blank'><strong>MTBLS943</strong></a>.</p><p>I<strong>nterspecific chemical variability assay</strong> protocols and data are reported in study <a href='https://www.ebi.ac.uk/metabolights/MTBLS944' rel='noopener noreferrer' target='_blank'><strong>MTBLS944</strong></a>.</p>
