20.500.12556/DKUM-66774 The Influence of various origins of first calving Simmental and Black-White cows on production and content of milk Utjecaj podrijetla simentalske i holstein pasmine krava na proizvodnju i sastav mlijeka u prvoj laktaciji A total of 1 070 Simmental and Black-White first calving cows and the same number of mother cows were investigated. The first calving cows originally arrived from Slovenia, the Netherlands, Germany and Denmark. No statistically significant differences were established in the milk production and quality of milk between the first calving cows from abroad compared to the first calving Slovenian cows. Statistically significant higher milk production (8 004 ± 981 kg; P ≤0.001) had mother cows of the imported Black-White compared to the Slovene (6 514 ± 1 142 kg) ones. There were no statistically significant differences, in the milk production and quality of milk, between the imported mothers of first calving cows of Simmental breed comparing with Slovenian mothers of first calving cows of the same breed. The milk production between the mothers and their Simmental daughters had a statistically significant correlation (rp = 0.125; P ≤ 0.01). The higher correlation coefficient for this characteristic was established between the Black-White mothers and their daughters (rp = 0.302; P ≤ 0.001). Among the milk production of first calving cows and protein content in milk a statistically negative significant correlation (rp = -0.198; P ≤ 0.001) was established. This result confirmed that the purchase of more expensive animals with better genetic potential is economically unjustified for the breeder who does not reach intensive technology of basic quality voluminous fodder. Cilj istraživanja bio je utvrditi, da li su krave u prvoj laktaciji stranog podrijetla usporedive s kravama prve laktacije iz slovenskog uzgoja. Analizirano je 1 070 krava simentalske i holstein pasmine u prvoj laktaciji i jednaki broj njihovih majki. Po podrijetlu krave su bile iz Slovenije, Nizozemske, Njemačke i Danske. Nismo utvrdili statistički signifikantne razlike u proizvodnji i sastavu mlijeka između stranih i domaćih krava u prvoj laktaciji. Statističko signifikantno (P ≤ 0,001) višu mliječnost imale su majke holstein pasmine iz uvoza (8 004 ± 981 kg; P ≤ 0,001) u usporedbi sa slovenskim (6 514 ± 1 142 kg). Kod simentalske pasmine stranih i slovenskih majki nije bilo statistički signifikantnih razlika u proizvodnji i sastavu mlijeka. Utvrđena je signifikantna korelacija (rp = 0,302; P ≤ 0,001) između mliječnosti majki i njezinih kćeri kod simentalske pasmine. Viši korelacijski koeficient za to svojstvo utvrđen je između majki i kćeri holstein pasmine (rp = 0,302; P ≤ 0,001). Utvrđena je negativna statistički signifikantna korelacija (rp = -0,198; P ≤ 0,001) između proizvodnje mlijeka krava u prvoj laktaciji i sadržaja bjelančevina. Ovi rezultati pokazuju, da je nabava skupih životinja s boljim genetskim proizvodnim potencijalom ekonomski neopravdana za proizvođače, koji ne mogu savladati tehnologiju intenzivne proizvodnje voluminozne krme visoke kakvoće. cattle Simmental Black-White milk production protein fat govedo Simental Holstein črno-bela proizvodnja mleka beljakovine maščobe true false true Angleški jezik Hrvaški jezik Znanstveno delo 2017-07-10 09:38:08 2017-07-10 09:39:14 2022-08-01 13:09:20 2019-07-11 15:58:29 2004 0 0 str. 275-283 št. 4 Letn. 54 2004 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0026-704X 636.2:637.12 85783 2196268 0026-704X URN:SI:UM:DK:VIVQDP8M Mljekarstvo_2004_Janzekovic,_Skorjanc,_Smolinger_The_Influence_of_various_origins_of_first_calving_Simmental_and_Black-White_cows_on_pro.pdf Mljekarstvo_2004_Janzekovic,_Skorjanc,_Smolinger_The_Influence_of_various_origins_of_first_calving_Simmental_and_Black-White_cows_on_pro.pdf 1 A6D495615BF832B2EF6EA9A58C7637DA 42933641dbbf5b4b4c2964e55a312846b7a0fd32abb2c9a508032a1123a5a5a0 62c12ca9-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/782a737c-1876-4596-9ead-89bac13a6674 https://dk.um.si/Dokument.php?lang=slv&id=113930 http://hrcak.srce.hr/1653 1 https://dk.um.si/Dokument.php?lang=slv&id=113929 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
