Milk Production and Feed Base on Family Farms within the Agricultural Cooperative Šentjur

Namen diplomskega dela je bil primerjati različna odkupna območja mleka po kvalitativnih lastnostih. Tako smo med seboj primerjali mleko odkupljeno na območju Kmetijske zadruge Šentjur, odkupnem območju Mlekarne Celeia in odkupljeno mleko celotnega območja Slovenije. Prireja mleka je v veliki meri odvisna tudi od prehrane krav, zato nas je zanimalo, kako imajo boljše družinske kmetije na območju Kmetijske zadruge Šentjur izravnane krmne obroke za krave molznice. Zbrali smo 36 mesečnih obračunov. Proučevali smo odkupljene količine mleka, vsebnost mikroorganizmov, skupno število somatskih celic ter vsebnost maščob in beljakovin za obdobje 2006 - 2008. Na obravnavanih kmetijah smo ugotovili dejansko sestavo krmnih obrokov. Krmne obroke smo ovrednotili na podlagi tabelarnih vrednosti. Živalim je bil skozi vso leto na voljo zimski krmni obrok na osnovi koruzne in travne silaže, sena ter dodatka koncentrirane krme. Molznice so bile ustrezno oskrbljene z energijo medtem, ko je bil pri beljakovinah ugotovljen primanjkljaj (6 % prebavljivih surovih beljakovin). Odkupljeno mleko iz obravnavanih območij se ni razlikovalo po bistvenih mikrobioloških kakovostnih postavkah.The purpose of the thesis was to compare different areas of milk collection considering qualitative characteristics. Milk collected within the agricultural cooperative Šentjur, the diary Mlekarna Celeia and milk collected in whole Slovenia was compared. Milk production depends on cow nutrition in majoritytherefore the main interest was to investigate how well situated family farms feed diary cows in the area of agricultural cooperative Šentjur. Thirty-six monthly settlements were collected. The amount of collected milk, the content of microorganisms, the number of somatic cells, fat and protein content were examined for the period 2006 to 2008. On farms involved in the research, the typical feed content was determined. Feed was assessed on the basis of tabular data. Animals got winter-feed based on maize and grass silage, hay and the additive of concentrated feed during the whole year. Diary cows were suitable supplied with energy, however, there was a lack of protein established (6 % of digestible raw proteins). Considering the main microbiological quality items, milk collected from the areas in question was not different
