Abstract
Biljka kukuruza je najvažnija silažna kultura koja se koristi kao glavno voluminozno krmivo u hranidbi visokomliječnih krava. Konzerviranje biljke kukuruza se postiže u anaerobnim uvjetima fermentacijom ugljikohidrata u kiseline. Cilj ovog diplomskog rada bio je utvrditi hranidbenu vrijednost i kvalitetu fermentacije 124 uzoraka kukuruznih silaža s 20 farmi muznih krava koji su analizirani NIR spektroskopijomu laboratoriju pokušališta Agronomskog fakulteta Centar za travnjaštvo na Medvednici obzirom na slijedede kemijske parametre: suha tvar(ST), kiselost (pH vrijednost), metabolička energija (ME), organska tvar (OT), probavljivost OT u ST (D – vrijednost), škrob, sirovi proteini (SP) i neutralna detergentvlaknina (NDV). Rezultati istraživanja ukazuju na prosječan visoki sadržaj ST analiziranih uzoraka kukuruznih silaža (379,13 g ST kg-1 svježeg uzorka), visoku D-vrijednost (74,06 %), poželjan sadržaj ME (11,53 MJ kg-1 ST) i škroba (349,46 g kg-1 ST). Obzirom na procijenjene vrijednosti kemijskih parametara, analizirani uzorci kukuruznih silaža (n=124) ukazuju na visoku hranjivost.
Abstract (english)
Most of the maize produced is used for feeding livestock. Maize silage is the most important forage in the feeding programme of dairy farms. The aim of this graduate paper was to determine the nutritional value and quality of the fermentation of 124 samples of maize silage from 20 dairy farms analysed by NIR spectroscopyin the Grassland Research Center of the Faculty of Agriculture. The following chemical parameters were peredicted: dry matter (DM), acidity (pH), metabolic energy (ME), organic matter (OM), the digestibility of OM in DM (D-value), crude proteins (CP) and neutral detergent fiber (NDF). The analysed maize silage samples were in average of high DM concentration (379,13 g DM kg-1fresh samplehigh D-value (74,06 %), recommended ME (11,53 MJ kg-1DM) and starch (349,46 g kg-1DM). It was concluded that, considering the predicted analytical parameters, the analysed maize silages were of high nutritive value.
