20.500.12556/DKUM-63901 Model za podporo pri odločanju uporabe tehnologij pridelave krme The decision support model for forage production Za iskanje možnosti učinkovitejšega gospodarjenja na živinorejskih kmetijah je prehrana živali zagotovo področje, ki to dopušča. Četudi se številni raziskovalci lotevajo raziskav pridelave travniške krme z njiv le s tehnološkega vidika, se ugotovitve navezujejo tudi na ekonomiko pridelave. Za ocenjevanje ekonomske upravičenosti uporabe tehnologij ali odločitev zanje si pomagamo z uporabo simulacijskih modelov, programskih orodij ter primernih metod. Pri računanju krmnih obrokov prehranske strokovnjake pretežno zanima pokritost potreb živali glede na intenzivnost proizvodnje, medtem ko agrarne ekonomiste zanima zlasti stroškovni vidik v razmerju s prihodki. V nalogi z vidika pogojev za pridelavo travniške krme z njiv ugotavljamo njihov vpliv na sestavo in vrednost krmnih obrokov za krave molznice. Razvito je orodje, ki poleg ocenjevanja ekonomskih vplivov omogoča tudi načrtovanje pridelave krme ter ocenjevanje primernosti tehnologij s stroškovnega vidika. Pri tem je uporabljena metoda klasičnega determinističnega linearnega programiranja. V nalogi je pristop testiran na primeru ravninskega kmetijskega gospodarstva, ki je specializirano v prirejo mleka. Dobljeni rezultati kažejo prednosti in slabosti linearnega programiranja. Hkrati je ugotovljeno, da je linearno programiranje lahko primerno orodje za načrtovanje pridelave krme in ocenjevanje tehnologij, a je pri tem kakovost rezultatov in razpoložljivost vhodnih podatkov pomembna omejitev. In the quest for more effective management of livestock farms, animal nutrition is an area that offers a wide range of possibilities. Although numerous researches focus on the production of forage on temporary grassland (which is part of arable land) only in technological terms, their findings always relate to the economics of production, too. Simulation models, software tools and suitable methods are applied to assess the economic viability of using or deciding for specific technologies. In calculating feed rations, nutrition experts primarily examine the coverage of animal needs in relation to the intensity of production, while agricultural economists are interested in the lowest cost of feed rations. In the thesis, we examine these topics in terms of conditions for the production of temporary grassland forage and their impact on the composition and value of feed rations for dairy cows. We developed a model which, in addition to impact assessment, also helps us plan forage production and assess the suitability of technologies. The method of traditional linear programming is applied. In the thesis, the model and the method are tested for a flatland dairy farm. Based on the results obtained we presented both advantages and disadvantages of linear programming. We found that linear programming can be a suitable tool for the planning of forage production and assessing technologies, with the quality of results and availability of input data being an important limiting factor. travniška krma z njiv krmni obrok za krave molznice ekonomika simulacijski model matematično programiranje linearno programiranje forage from temporary grassland dairy cow ration economics simulation model mathematical programming linear programming true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2016-09-19 10:28:36 2016-10-06 12:16:11 2022-07-04 03:05:48 2019-07-11 13:43:35 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:TG6AATAP MAG_Moljk_Ben_2016.pdf MAG_Moljk_Ben_2016.pdf 1 7EFF90781955E8C1F4449D3093584953 a1e6a4c83b2b918ef2bba2312a38a7cf6b0cfa978d958e2fdb74838b07f2d7d1 91c8f8a2-7c0d-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=105593 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
