The farms included in the study are divided in diet and breeding. The animals were divided into groups according to age at first calving. The age of first calving for each group in the two farms has been traced. This study aims to track the age of first calving in cows of Holstein-Friesian breed and milk quantity on first lactation in both farms. The survey results indicate an optimal age for first calving at Farm A - 24 months of age, and for Farm B - 29 months of age. In the respective ages the total milk is highest.","is_dataset_classified":null,"base_score":1.3862943611198906,"endowment":1.3862943611198906,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"26207759","pmcid":null,"openalex_id":"https://openalex.org/W2561363825","authors":[],"funders":[],"total_grants":0,"fwci":0.2733,"citation_percentile":0.73374277,"influential_citations":0,"citation_trend":[{"year":2018,"count":1},{"year":2020,"count":1},{"year":2025,"count":1}],"oa_status":"gold","license":"cc-by-nc-sa","oa_locations":[{"url":"https://doi.org/10.20546/ijcmas.2016.503.031","host_type":"journal"},{"url":"https://doi.org/10.20546/ijcmas.2016.503.031","host_type":"publisher"}],"fields_of_study":["Genetic and phenotypic traits in livestock","Reproductive Physiology in Livestock","Effects of Environmental Stressors on Livestock"],"mesh_terms":[],"keywords":["Ice calving","Breed","Animal science","Lactation","Holstein Cattle","Biology","Dairy cattle","Pregnancy"],"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":"2026-08-17T01:04:07.338736Z","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":[]}
