20.500.12556/DKUM-75309 Prehranski parametri travne silaže za krave molznice Nutritional parameters of grass silage for dairy cows Namen diplomske naloge je primerjava in analiza prehranskih in kakovostnih parametrov travnih silaž pridelanih na severovzhodu Slovenije. Primerjavo parametrov smo izvedli z analizami iz prejšnjih let in s Hoffmanovimi (2017) priporočili za kakovostne silaže. Zatem smo poiskali korelacije med dobljenimi parametri. Zbrali smo 77 analiz silaž, ki so bile analizirane v nemškem laboratoriju Landwirtschaftliche Kommunikations und Service (LKS)po metodi NIRS in minerali po klasični metodi. Silaže so bile analizirane na naslednje parametre: suha snov, surov pepel, surove beljakovine, surove maščobe, sladkor, HFT, pH, amoniak, topnost beljakovin, količina pepsinsko netopnih beljakovin in na minerale kalcij, fosfor, natrij, kalij, klor in žveplo. Podatke smo vstavili v excel in jih nato obdelali z SPSS 25.0. Naše analize smo primerjali z analizami iz prejšnjih let, vsebnosti pri parametrih so bile podobne. Vsebnost sušine iz naših analiz so bile pri prvem odkosu 42,8 % in pri drugem 42,2 %, silaže iz obdobja 2000 do 2010 so pa imele vsebnosti 44,2 % in v letu 2014 40,8 %, silaže iz leta 2016 pa so imele 43,2 %. Silaže so po Hoffmannovih (2017) priporočilih vsebovale preveč sušine, saj Hoffmann (2017) priporoča 30 – 40 % sušine. Pri ugotavljanju korelacij smo našli veliko korelacij, korelacije med nekaterimi parametri so pozitivne druge negativne. Korelacije so pomembne, da lahko predvidevamo vsebnost parametrov katerih nismo analizirali. The thesis deals with the nutritional and quality parameters of grass silage grown in the northeast of Slovenia. The analyzes we made are compared to analyzes from previous years and to Hoffmann‘s (2017) recommendations and we also look for correlations between different parameters. In the diploma, we collected 77 analyzes, which were sent to the German laboratory Landwirschaftliche Kommunikations und Service (LKS), where silage was analyzed by the NIRS method and minerals by the classical method. The samples were analyzed for the following parameters: dry matter, crude ash, crude protein, crude fat, sugar, HFT, pH, ammonia, protein solubility, amount of pepsin-insoluble protein, and minerals calcium, phosphorus, sodium, potassium, chlorine and sulfur. Data were inserted into the excel and then processed with the SPSS 25.0. We compared the analyzes from previous years with our analyzes. The contents of the parameters were similar. The drought content of our analyzes was 42.8 % in the first and 42.2 % in the second harvest, while the silage from 2000 to 2010 had 44.2 %, in 2014 it was 40.8 %, the silage from 2016 had 43.2 %. According to Hoffmann our silages contained to much dry matter because he recommends 30 – 40 %. As correlations go, we found many correlations, some were positive and some negative. Correlations are important so we can predict the content of parameters that we have not analyzed. siliranje prehranski parametri povezave med parametri vsebnosti silaž ensiling nutritional parameters parameter correlation silage content true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2019-10-15 08:45:07 2019-11-19 10:23:02 2022-08-09 11:11:08 2019-12-10 08:32:26 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:UWQRSWFN VS_Prah_Tomaz_2019.pdf VS_Prah_Tomaz_2019.pdf 1 EC9F52DA3BAE9FF658A968E849714092 b8e7e13a6477b0d813b20eecc46ef3e05c449691ff84ae41fc45c5d0fa26da62 1c92b230-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/a1543efa-056c-492c-8172-ffbafd215af3 https://dk.um.si/Dokument.php?lang=slv&id=139255 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
