Portulaca oleracea L. extract (POE) shows potential for enhancing poultry production, but its effects on Wenchang chickens are unclear. A total of 90 one-day-old female Wenchang chickens were randomly allocated into three treatment groups: a control group (CON) receiving a basal diet, and two experimental groups (POL and POH) receiving the basal diet supplemented with 0.2 % and 0.4 % POE, respectively. Compared to the CON group, the POL group exhibited significantly higher average daily gain (ADG) and lower feed conversion ratio (FCR) (P < 0.05). POL also significantly enhanced immune function: increased serum immunoglobulins (IgG, IgA, IgM), cytokines (IL-1, IL-4, IFN-γ), secretory IgA (sIgA), and spleen index (P < 0.05). Meat quality improved in POL, with reduced drip loss, cooking loss, and shear force, alongside increased flavor-enhancing amino acids and inosine monophosphate (IMP) (P < 0.05). Jejunal morphology (villus height, VH/CD ratio) and tight junction protein (Claudin-1, Occludin, ZO-1) expression were upregulated in POL (P < 0.05). Gut microbiota analysis revealed POL increased Bacteroides and Faecalibacterium abundance while lowering the Firmicutes / Bacteroidota ratio (P < 0.05). Metabolomics indicated enrichment in tryptophan, arginine, and proline metabolism pathways in POL. Dietary 0.2 % POE improved growth, immunity, and meat quality in Wenchang chickens, potentially mediated by enhanced intestinal health and modulation of tryptophan, arginine, and proline metabolism.

View all literature mentionsHigh quality ribosomal RNA databases providing comprehensive, quality checked and regularly updated datasets of aligned small (16S/18S, SSU) and large subunit (23S/28S, LSU) ribosomal RNA (rRNA) sequences for all three domains of life (Bacteria, Archaea and Eukarya). Supplementary services include a rRNA gene aligner, online tools for probe and primer evaluation and optimized browsing, searching and downloading on the website. The extensively curated SILVA taxonomy and the new non-redundant SILVA datasets provide an ideal reference for high-throughput classification of data from next-generation sequencing approaches. Alignment tool, SINA, is available for download as well as available for use online.
View all literature mentionsA multi-institutional effort to identify and quantitate, using a systems biology approach and sophisticated mass spectrometers, all of the major - and many minor - lipid species in mammalian cells, as well as to quantitate the changes in these species in response to perturbation. The goal of their research is to better understand lipid metabolism and the active role lipids play in diabetes, stroke, cancer, arthritis, Alzheimer's and other lipid-based diseases in order to facilitate development of more effective treatments. Resources available include: LIPID MAPS publications, detailed biochemical pathways, improved protocols for lipid separation and quantification, analytical tools for determining lipid quantitation, structure drawing tools for automatically drawing lipid molecular structures in stereochemical detail, and experimental data. The LIPID MAPS organization includes six lipidomics core laboratories, each specialized in extracting, identifying, and quantifying one of the major categories of mammalian lipids: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, sterol lipids, and prenol lipids. Other core laboratories and bridge projects include bioinformatics, mass spectrometric imaging, lipid synthesis, oxidized lipids, and macrophage biology and genomics.
View all literature mentionsCurated collection of human metabolite and human metabolism data which contains records for endogenous metabolites, with each metabolite entry containing detailed chemical, physical, biochemical, concentration, and disease information. This is further supplemented with thousands of NMR and MS spectra collected on purified reference metabolites.
View all literature mentionsIntegrated database resource consisting of 16 main databases, broadly categorized into systems information, genomic information, and chemical information. In particular, gene catalogs in completely sequenced genomes are linked to higher-level systemic functions of cell, organism, and ecosystem. Analysis tools are also available. KEGG may be used as reference knowledge base for biological interpretation of large-scale datasets generated by sequencing and other high-throughput experimental technologies.
