Abstract:V diplomskem delu smo razvili linearni model za sestavo letnega in zimskega krmnega obroka. Krmni obrok je bil sestavljen za krave molznice na primeru lastne konvencionalne kmetije. Ker vemo, da cene pri prodaji mleka zelo nihajo, je potrebna prilagoditev na optimiranje stroškov. Različni avtorji poudarjajo, da lahko stroški krmnega obroka dosežejo tudi do 65 % vseh skupnih stroškov prireje. Iz tega vidika je torej optimiran krmni obrok izjemnega pomena. Minimizirali smo stroške krmnega obroka in ga naredili ustreznejšega z vidika hranilnih vrednosti. V Microsoft Office Excelu smo razvili program in s pomočjo Reševalnika, ki je eno izmed osnovnih Excelovih orodij, dobili najustreznejše obroke, ki so pokrili vse potrebe po hranilnih snoveh. Za krmo, ki jo pridelamo doma: travno silažo, seno in pašo, smo izračunali lastno ceno, za vso ostalo krmo in dodatke pa smo uporabili nabavno ceno. Primerjali smo krmni obrok, ki je trenutno pokladan na kmetiji in krmni obrok, ki smo ga s pomočjo linearnega programa sestavili.

Title:Development of a linear calculation model for dairy cow feed rations
Abstract:In this reserach, we developed a linear model fort he design fort he annual and winter feed meals. A forage meal was designed on the basis of dairy cows of own conventional farm. While prices in milk sales are fluctuating, adjustment to cost optimization is needed. Diffrent authors are pointing out that feeding costs can reach up to 65 % of total production costs, and that's why an optimized feed meal is very important. We minimized the cost of feeding meal and made it more appropriate to nutrution value. We developed a program Microsoft Office Excel and with the help of one of the basic Excel tools, we got the cheapest meals that covered all the needs for nutrients in the meals. For feed produced at home, grass silage, hay and pasture, we calculated our own price and for all other feed and the additions, the purchase pride was usef. At the end, we compared the feed meal, wich is currently harvested on the farm and the feed meal, wich was designed with the help of our linear model that we have designed.
