Abstract:Vrednotenje oskrbljenosti prežvekovalcev z beljakovinami je pomembno predvsem iz ekonomskih, proizvodnih in tudi zdravstvenih razlogov. V magistrskem delu smo na podlagi ekonomsko izračunanega obroka med seboj primerjali slovenski sistem prebavljivih beljakovin, slovenski sistem presnovljivih beljakovin in nemški sistem uporabnih surovih beljakovin. Preračun smo naredili po sistemu presnovljivih beljakovin in uporabnih surovih beljakovin. Podatke o vsebnosti hranljivih snovi smo za domačo krmo pridobili iz analiz krme, za dokupljeno pa smo jih povzeli iz preglednic LfL. Osnova je bila dnevni obrok za 20 litrov mleka. Po sistemu presnovljivih beljakovin in izračunu smo ugotovili, da imamo v obroku primanjkljaj presnovljivih beljakovin glede na razpoložljiv dušik, ki znaša 216,45 g, ter presežek presnovljivih beljakovin glede na razpoložljivo energijo, ki znaša 529,23 g. Izračun smo nato naredili še po nemškem sistemu uporabnih surovih beljakovin. Ugotovljen je bil minimalen primanjkljaj 10,3 g nXP. Po tem sistemu smo naredili tudi izračun za dnevno mlečnost 25 litrov, ki ustreza potrebam. V nalogi smo izračunali tudi DCAB razmerje, ki nam pove razmerje med pozitivnimi kationi natrija in kalija v razmerju z negativnimi anioni klora in žvepla. Podatke o vsebnosti mineralnih snovi v domači krmi smo pridobili iz analiz krme, za dokupljeno pa smo jih povzeli iz preglednic. Za krave molznice je priporočeno razmerje višje od 150 meq/kg SS. Obstoječi obrok ima razmerje 368,06 meq/kg SS, obrok z dnevno mlečnostjo 25 litrov dnevno pa 308,43 meq/kg SS.

Title:Calculation of utilizable proteins and the dietary cation-anion difference in dairy cow feed
Abstract:Supply evaluation for ruminants is important mostly from economic, production and health reasons. This thesis is based on an economically calculated ration for dairy cows. The Slovene system of digestible proteins, the Slovene system of metabolic protein and the German system of utilizable crude proteins were compared. The new calcualation was made via the system of metabolic proteins and utilizable crude proteins. Data about content of nutrition staff was collected from the analysis for home produced feed. For bought feed, data from tables LfL were used. The base was the feed ration for 20 liters of milk. The results of the calculation with the system of metabolic protein indicated a shortage of 216,45 g nitrogen metabolic proteins and sureplus of 529,23 g energy metabolic proteins. The same calculation with the German system of utilizable crude proteins was undertaken. In this calculation a shortage of 10,3 g uCP was found. With this sistem, new calculations for a feed ration for 25 liters of milk per day was undertaken. Daietary Anion-Cation Balance (DCAB) was also included in the research. This is basicly a ratio between positive cations of sodium and pottasium in relation to negative anions of chlorine and sulfur. The data for feed mineral content was obtained by analysing home produced feed and from tables for bought feed. It is reccomended for dairy cows that DCAB should be higher than 150 meq/kg DM. The present day feed ratios have a DCAB of 368,06 meq/kg DM, and the feed ratios for 25 liters are 308,43 meq/kg DM.
