DEVELOPMENT MODEL FOR OPTMINIZATION FEED RATION TO DAIRY COWS

Pri prireji mleka se srečujemo z neprestanimi nihanji cen produktov v našem primeru mleka in nihanjem cen krmnih surovin, hkrati pa se soočamo z vedno ostrejšimi predpisi in zahtevami. V okolju zaostrene konkurence se morajo tudi kmetijski obrati povsem prilagoditi tržnim razmeram in konkurenci, da pa smo lahko konkurenčni, moramo proizvajati kvalitetne izdelke za najnižjo ceno. Namen diplomskega delaje predstaviti enega izmed načinov kako pripraviti najugodnejši krmni obrok za krave molznice z pokritimi potrebami. Praktično bomo prikazali dva primera obrokov in sicer enega z ročnim vnašanjem surovin in drugega z uporabo razvitega modela za optiminizacijo krmnih obrokov pri kravah molznicah. Za vrednotenje beljakovin uporabljamo presnovljive beljakovine in za vrednotenje energije pa NEL – e . Model je razvit v Excel - ovem okolju za reševanje pa uporabljamo dodatek (WB!9). There is constantly product price fluctuation - in our case milk price fluctuation - and fodder price fluctuation in milk production. At the same time we are facing with stricter regulations and demands. In intensified competition environment the agricultural plant has to adjust completely to the market conditions and to the competition. To be competitive, we have to produce quality products for lower price. The intention of the degree paper is to present one of the manners how to prepared cheapest fodder meal for dairy cows with covered needs. We will practically show two examples of meals for dairy cows. One of the examples is entering raw material by hand and the second one with using developed model for optimisation fodder meals for dairy cows. For the evaluation of proteins are used metabolic proteins and for the evaluation of energy is used NEL – e. The model is developed in Excel, for solving is used file (WB!9).
