{"doi":"10.30782/uluvfd.434395","title":"The Influence of Calving Year on Milk and Milk Components in Dairy Cattle","abstract":"<jats:p xml:lang=\"en\">The aim of this study was to identify the effect of calving year on milk yield and milk composition traits in Holstein and Jersey cattle raised in Marmara and the Black Sea Regions of Turkey, respectively. The data set consisted of 582 dairy cows, which were 306 Holstein raised and 276 Jersey cows calving from 2011 to 2013. In this study, animals were identified and selected to be genotyped for the DGAT1 gene based on farm records. Except for fat yield, the effect of calving year on test day milk yield (TDMY), 305-day milk yield (305 DMY), fat percentage, protein percentage and protein yield of Jersey cows were affected by calving season. The effect of calving year on TDMY, 305 DMY, fat percentage, fat yield, protein percentage and protein yield of Holstein cows were found to be statically significant. In conclusion, in 2011 to 2013, milk yield and its composition in both Holstein and Jersey cows were significantly related to calving years. </jats:p>","journal":"Uludağ Üniversitesi Veteriner Fakültesi Dergisi","year":2018,"id":677143,"datarank":0.10397207708399181,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"self_citation_contribution":0.10397207708399181,"citation_network_contribution":0.0,"self_endowment_contribution":0.10397207708399181,"citer_contribution":0.0,"corpus_percentile":21.9,"corpus_rank":10026,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":true,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1769259,"name":"Ertuğrul KUL","orcid":"0000-0003-4961-5607","position":1,"is_corresponding":false},{"id":1769257,"name":"Özden ÇOBANOĞLU","orcid":"0000-0001-9633-634X","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"resolved":true,"title":"The Influence of Calving Year on Milk and Milk Components in Dairy Cattle","abstract":"<jats:p xml:lang=\"en\">The aim of this study was to identify the effect of calving year on milk yield and milk composition traits in Holstein and Jersey cattle raised in Marmara and the Black Sea Regions of Turkey, respectively.
