20.500.12556/DKUM-20981 Mlečnost krav po spremembi sistema reje Milk yield after the change of farm system Cilj naloge je bil prikazati spremembo v mlečnosti v času selitve živali iz hleva z vezano rejo in molžo na mlekovod v hlev proste reje in molžo v molzišču. V obdobju šestih mesecev smo opazovali 22 krav molznic. V raziskavo so bile vključene le živali, ki so bile v omenjenih šestih mesecih v stadiju laktacije. Nadalje smo prikazali tudi mlečnost kmetije po letih pred in po selitvi, na podlagi česar smo ugotovili, da se je mlečnost po selitvi v hlev s prosto rejo zmanjšala, vsebnost beljakovin in maščob v mleku pa povečala. Porast maščob in beljakovin je tudi posledica kakovostnejšega krmnega obroka, ki se živalim v novem hlevu poklada z mešalno prikolico. The aim of the thesis was to show the change in milk yield during the migration of animals from the tied breeding barn and milking by circulating milk-gauge to the free range system and milking in milking parlor. We observed 22 cows for six months. The study included only animals which were in those six months in stage of lactation. Furthermore, we have shown yearly milk yield of the farm before and after the move. On the basis of which we have found that after moving to the free-range stable the milk yield has reduced, while protein and fat content of milk has increased. Increase in fat and protein is probably caused by more high-quality feed which is added to the animals by mixing trailer. mlečnost krave molznice vezana reja prosta reja milk yield cow cows range bound free range true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-10-13 19:29:55 2011-11-14 14:09:44 2022-04-14 08:26:15 2023-12-27 03:27:11 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:6ICOLMUN UNI_Marin_Polona_2011.pdf UNI_Marin_Polona_2011.pdf 1 C1A24B99EF198B801BA6D35ADEB375B5 408887eac05584455e9711dc06ba210d66c2f56f2e019203ccbf4073b164387c c10a4727-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/5f6cc93f-1d6c-4a08-9a5c-9d6070c9eb4c https://dk.um.si/Dokument.php?lang=slv&id=26376 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
