20.500.12556/DKUM-15683 PRIMERJAVA ENERGETSKE UČINKOVITOSTI DVEH MOLZNIH SISTEMOV ENERGY EFFICIENCY COMPARISON OF TWO MILKING SYSTEMS V raziskavi smo merili količino porabljene vode, čas in električno energijo med molžo na dveh kmetijah z različnim sistemom reje in načinom molže. Kmetija 1 ima privezan način reje z mlekovodom na štiri molzne enote, kmetija 2 pa ima prosto rejo z molziščem autotandem (2 x 3). Povprečni čas molže posamezne krave je bil pri mlekovodu 7.46 min, na molzišču autotandem pa 6.42 min. Povprečna porabljena električna energija glede molže je bila na mlekovodu 0,0882 kWh/kravo, na molzišču autotandem pa 0,083 kWh/kravo. Povprečna porabljena električna energija glede namolzenega mleka je na mlekovodu 0,0092 kWh/kravo, na molzišču autotandem pa 0,0073 kWh/kravo. V vseh izbranih parametrih po porabi električne energije ni prihajalo do statistično značilnih razlik. Porabljena količina vode je v obeh molznih sistemih znašala 70 l vode za eno pranje molznega sistema. In the study, the quantity of water, the time and the energy used during milking were measured on two farms with different livestock housing system and different milking method. The farm 1 uses the tied-stall system with milk pipeline per 4 milking units, while the farm 2 uses the free-housing system with auto tandem milking parlour (2 x 3). The average time of milking an individual cow was 7.46 minutes on the milk pipeline and 6.42 minutes on the auto-tandem parlour, which is almost a minute less than on the milk pipeline. The average amount of the electricity spent per a cow regarding the time of milking was 0.0882 kWh on the milk pipeline and 0.083 kWh on auto-tandem parlour. The average electricity spent per a cow regarding its quantity of milk is 0.0092 kWh on the milk pipeline and 0.0073 kWh on the auto-tandem parlour. In all chosen parameters according to the use of electricity no statistically significant differences occurred. The quantity of water consumed was equal in both milking systems, i. e., 70 l of water for one washing of the milking system. mlekovod/ autotandem/ poraba vode/ poraba električne energije milkpipeline auto tandem parlour water consumption electric currend consumption true true false Slovenski jezik Angleški jezik Diplomsko delo 2010-09-16 18:45:55 2010-10-13 09:19:37 2022-04-13 07:30:12 2023-12-19 03:27:10 2010 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:TPUO4GCN UNI_Plibersek_Marko_2010.pdf UNI_Plibersek_Marko_2010.pdf 1 65031C5A2FCB35B6D9B148C2A6FE525A 14830dcdd732e5957de04977204aff56d6ae96a689e9aef5122fa12eedb73a07 75e7f830-7c04-11eb-bb7a-00155d0001ca 20.500.12556/dkum/e22cd20d-835a-4b38-94a1-197d3a2b0dc0 https://dk.um.si/Dokument.php?lang=slv&id=17372 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
