The serum concentrations of lipid metabolites were also investigated at the fecal collection dates. Serum and feces from the ewe-reared groups at 33, 48, and 63 days of age were used as controls. The alpha diversity increased significantly after weaning and with the aging of the lambs. Levels of Ruminococcaceae, Lachnospiraceae, and Ruminococcus varied significantly according to the weaning treatment in lambs (P < 0.05). Butyrate-producing gut bacteria such as Ruminococcaceae_UCG-010, Ruminococcaceae_UCG-013, Ruminococcaceae_UCG-014, Ruminococcaceae_UCG-005, Ruminococcaceae_UCG-002, Lachnospiraceae_AC2044_group, and Lachnospiraceae_NK4B4 were identified as significantly increased genera (P < 0.05) in the feces of weaned Chongming white lambs. Additionally, the abundance of fiber degradation-associated bacteria including Ruminococcaceae_UCG-005, Ruminococcus_1, and Ruminococcus_2 significantly increased with lamb weaning age (P < 0.05). Correlation analysis showed that Lachnospiraceae_AC2044_group, norank_f__Bacteroidales_S24-7_group, and Ruminococcaceae_UCG_005 were negatively correlated, and Lachnoclostridium was positively correlated with levels of cholesterol, while Blautia showed positive correlation with low-density lipoprotein cholesterol in serum samples from weaned lambs. This study helped to understand the maturing development of gut microbiota in Chongming white goats under weaning stress. KEY POINTS: • Effects of weaning age on the gut microbiota diversity in Chongming white goat lambs were studied. • Some butyrate-producing gut bacteria were significantly increased after weaned. • Correlations of gut microbiota and lipid metabolites were analyzed.","is_dataset_classified":null,"base_score":3.7612001156935624,"endowment":3.7612001156935624,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"33885927","pmcid":null,"openalex_id":"https://openalex.org/W3156507053","authors":[],"funders":[{"funder_name":"National Natural Science Foundation of China","grant_id":"31902149","title":null},{"funder_name":"Shanghai Agriculture Applied Technology Development Program","grant_id":"Z20200105","title":null},{"funder_name":"Shanghai Committee of Science and Technology","grant_id":"19140900100","title":null}],"total_grants":3,"fwci":2.2205,"citation_percentile":0.88991012,"influential_citations":0,"citation_trend":[{"year":2022,"count":10},{"year":2023,"count":8},{"year":2024,"count":12},{"year":2025,"count":12}],"oa_status":"closed","license":"https://www.springer.com/tdm","oa_locations":[{"url":"https://link.springer.com/content/pdf/10.1007/s00253-021-11301-2.pdf","host_type":"publisher"},{"url":"https://link.springer.com/article/10.1007/s00253-021-11301-2/fulltext.html","host_type":"publisher"},{"url":"https://doi.org/10.1007/s00253-021-11301-2","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/33885927","host_type":"repository"}],"fields_of_study":["Gut microbiota and health","Ruminant Nutrition and Digestive Physiology"],"mesh_terms":["Gastrointestinal Microbiome","Animals","Feces","Goats","RNA, Ribosomal, 16S","Sheep","Weaning"],"keywords":["Lachnospiraceae","Ruminococcus","Weaning","Biology","Feces","Gut flora","Endocrinology","Microbiology","Bacteria","Firmicutes","Biochemistry","16S ribosomal RNA","Goat","16S rRNA","Gut","Microbiota","Weaning Stress"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Zero hunger"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-03T04:55:48.012190Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
