Abstract:V magistrskem delu je bil razvit linearni model za sestavo krmnih obrokov za vse kategorije govedi na kmetiji. Najprej so bili za potrebe optimizacije razviti kalkulacijski sistemi v obliki simulacijskih modelov za vso domačo krmo. Rezultati so pokazali, da kmetija posluje ekonomsko upravičeno, saj je skupni finančni rezultat vseh proizvodenj na kmetiji pozitiven in znaša kar 38.939,38 €. Iz kalkulacij domače krme so bile pridobljene lastne cene vse uporabljene krme, ki so nato služile za realno oceno krmnih obrokov. Končno so bili razviti posamezni krmni obroki z najnižjimi možnimi stroški ob sočasnem zagotavljanju vseh hranilnih potreb živali. Primerjava trenutnih krmnih obrokov in izračunanih z ´Reševalcem` je pokazala, da so slednji v večini primerov stroškovno nižji od trenutnih. Izjema je le poletni krmni obrok za teleta v začetku pitanja, kjer je strošek trenutnega krmnega obroka enak strošku izračunanega krmnega obroka. Skupni stroški zimskih krmnih obrokov za celotno čredo so bili iz 47,47 €/dan znižani na 32,89 €/dan, kar znaša 14,58 €/dan manj. Prav tako so bili znižani skupni stroški poletnih krmnih obrokov za celotno čredo in sicer iz 36,39 €/dan na 24,83 €/dan, kar pomeni 11,56 €/dan manj. Razvit linearni model za sestavo krmnih obrokov bo predstavljal podporno metodološko orodje za nadaljnje gospodarno vodenje prehrane govedi na kmetiji.

Title:The use of economical optimization in cattle breeding: linear model development for the feed rations composition
Abstract:In this Masters thesis a linear model was developed for feed rations composition in all cattle categories on the farm. First the calculation system had to be developed for optimization needs in the form of simulation models for all domestic feed. Results showed the farm operates economically justified, because the financial result of all productions on the farm is positive and amounts to 38.939,38 €. From calculating domestic feed a private price was obtained for all used feed, which was then used for the real price in feed rations. Finally individual feed rations were developed with the lowest possible expense which at the same time insured all animal feeding needs. Comparison of current feed rations and calculated with the ´Rescuer` shoved that the latter are in most cases less expensive than the current. Summers feed ration for calf in the beginning of feeding is the only exception, because expense of current feed ration is the same as the calculated expense of feed ration. Common expense of winter feed rations for the whole flock were lowered from 47,47 €/day to 32,89 €/day, which is 14,58 €/day. Also the common expense of the summer feed rations for the whole flock were lowered from 36,39 €/day to 24,83 €/day which is 11,56 €/day less. The developed linear model for feed rations composition will represent the support methodological tool support for further economic management of feedstuffs on the farm.
