Abstract
Uspjeh proizvodnje u sektoru mliječnog govedarstva uvelike ovisi od biološki adekvatne i ekonomski opravdane hranidbe. Pri formulaciji obroka iz raspoloživih krmiva potrebno je uvažavati hranidbene potrebe životinja, fizička i kemijska svojstva krmiva, ograničenja u konzumaciji pojedinih krmiva te njihovu trenutnu cijenu. Uvažavajući istovremeno kompleksne hranidbene potrebe mliječnih krava i veliki broj ograničenja po pitanju konzumacije pojedinih krmiva, formulacija obroka predstavlja izazov čak i uz korištenje računala i specijaliziranih programskih rješenja. Cilj ovog rada je bio temeljem detaljno razrađenih primjera prikazati način i doprinos sastavljanja obroka s minimalnom cijenom koštanja korištenjem linearnog programiranja u R programskom okruženju. Primjenom ovog programa moguće je sastaviti obrok uvažavajući sve potrebe i ograničenja uz minimalnu cijenu koštanja. Praktična primjena ovakvih programskih rješenja još uvijek nedovoljno je zastupljena u praksi, a rezultati ovog rada trebali bi ukazati na doprinos njihove primjene, osobito kod malih i srednjih uzgajivača i u uvjetima velike varijabilnosti cijena krmiva na tržištu.
Abstract (english)
The success of production in the cow dairy sector largely depends on biologically adequate and cost effective nutrition. When formulating rations from available feedstuffs, it is necessary to take into account the nutritional needs of animals, physical and chemical properties of feedstuffs, restrictions on the consumption of certain feedstuffs and their current price. Taking into account at the same time the complex nutritional needs of dairy cows and a large number of restrictions on the consumption of certain feeds, ration formulation is a challenging task, even with the use of computers and specialized software solutions. The aim of this study was to examine the contribution of the least cost ration formulation using linear programming in the R programming environment. With this program, it is possible to formulate a ration, while satisfying all needs and restrictions at a minimum cost. The practical application of such software solutions is still insufficiently used in practice. The results of this study should point out the contribution of least cost ration formulation, especially in small to medium production systems and conditions of high variability of feedstuffs prices on the market.
