20.500.12556/RUL-188045 Kakovost doma pridelane krme kot osnova za prehod na prirejo senenega mleka diplomsko delo Quality of home-produced feed as a basis for transition to hay milk production B. Sc. thesis Kakovostna doma pridelana krma je ključna za dober osnovni obrok in ustrezno oskrbo krav s hranili. Namen diplomskega dela je analizirati doma pridelano voluminozno krmo in ugotoviti ali je na kmetiji možen prehod na seneno prirejo mleka. Poleg tega smo hoteli ugotoviti tudi ali kakovost krme ustreza sestavi kakovostnega osnovnega obroka. Kakovost različnih vrst krme smo določili na podlagi analiz pri kateri smo ugotovili vsebnost suhe snovi, surove vlaknine, surovih beljakovin, surovih maščob, surovega pepela in mineralov. S pomočjo DLG tabel in prebavljivostnimi koeficienti smo izračunali tudi vsebnost neto energije laktacije (NEL). Rezultate analiz smo primerjali z različnimi vrednostmi iz literature na podlagi kater smo tudi določili kakovostni razred krme. Ugotovili smo, da se je kakovost med posameznimi vrstami krme razlikovala. Glede na rezultate analiz smo sestavili obrok za krave molznice in preverili ali obrok ustreza njihovim potrebam. Količina zaužite suhe snovi, NEL in prebavljivih surovih beljakovin ter razmerje med kalijem in natrijem so bili ustrezni medtem, ko je bilo razmerje med kalcijem in fosforjem nekoliko porušeno. Za ustrezno razmerje bi bilo potrebno še dodatno prilagoditi osnovni obrok in vključiti več krme, ki vsebuje manj kalcija. Prehod na seneno prirejo mleka bi bil na kmetiji mogoč. Potrebne bi bile določene prilagoditve pri sestavi krmnega obroka in skladiščenju krme. High-quality home-produced forage is essential for formulating an adequate basal ration and ensuring an appropriate supply of nutrients for dairy cows. The aim of B.Sc. Thesis was to analyse home-produced forage and determine whether a transition to hay milk production would be feasible on the farm. In addition, we aimed to assess whether the quality of the forage was suitable for formulating a high-quality basal ration. The quality of different types of forage was determined based on laboratory analyses of dry matter, crude fibre, crude protein, crude fat, crude ash and mineral contents. The net energy for lactation (NEL) was also calculated using DLG tables and digestibility coefficients. The results of the analyses were compared with reference values from the literature, based on which the quality class of the forage was determined. The results showed that forage quality varied among the different types of forage. Based on the analytical results, a ration for dairy cows was formulated and its adequacy in relation to the cows' nutritional requirements was assessed. The amounts of dry matter intake, NEL and digestible crude protein, as well as the potassium-to-sodium ratio, were adequate, whereas the calcium to-phosphorus ratio was slightly imbalanced. To achieve an appropriate ratio, further adjustments to the basal ration would be necessary, including the incorporation of a greater proportion of forage with a lower calcium content. A transition to hay milk production would be feasible on the farm. However, certain adjustments to the composition of the feed ration and to feed storage practices would be necessary. govedo krave molznice prehrana živali krma kakovost seneno mleko prireja Slovenija diplomska dela cattle dairy cows animal nutrition feed quality hay milk production Slovenia true false false V.
