Milk production represents the possibility of earning monthly income and assures social security to many farms in Slovenia. In Slovenia the European rules and regulations on the quality of the delivered milk have been introduced, relating to the hygienic quality of milk and the count of somatic cells. The purchase price of the milk depends also on the protein and fat content. The aim of the research was to establish, whether the quality of the delivered milk complies with the prescriptions regulated by the Slovene legislation. The quality of the delivered milk in the area of the Šentjur agricultural cooperative (ACŠ) and in the entire area of Slovenia (SLO) has been studied. The bacteriological data in the individual quality classes, the data on the total count of somatic cels and the data on the fat and protein contents have been analyzed. 36 monthly accounts have been included in statistical processing. It has been established that the delivered milk of the areas in question does not differ in the relevant quality values. Proizvodnja mlijeka predstavlja mogućnost stjecanja mjesečnog dohotka i time osigurava socijalnu sigurnost mnogim seoskim gospodarstvima. U Sloveniji su na snazi europski propisi o kakvoći otkupljenog mlijeka i odnose se na higijensku kakvoću mlijeka te broj somatskih stanica. Otkupna cijena mlijeka ovisi i o postotku proteina i masnoće. Cilj rada bio je ustanoviti odgovara li kakvoća otkupljenog mlijeka aktualnim propisima u Sloveniji (SLO). Istraživana je kvaliteta otkupljenog mlijeka na području Kmetijske zadruge Šentjur (KZŠ) i cjelokupnom području Slovenije (SLO). Analizirani su bakteriološki podaci u pojedinim razredima kakvoće, podaci o ukupnom broju somatskih stanica te podaci o udjelu masti i proteina. U statističku obradu podataka uključeno je 36 mjesečnih obračuna. Utvrđeno je, da se otkupljeno mlijeko istraživanih područja ne razlikuje u bitnim elementima kakvoće.

A total of 1 070 Simmental and Black-White first calving cows and the same number of mother cows were investigated. The first calving cows originally arrived from Slovenia, the Netherlands, Germany and Denmark. No statistically significant differences were established in the milk production and quality of milk between the first calving cows from abroad compared to the first calving Slovenian cows. Statistically significant higher milk production (8 004 ± 981 kg P ≤0.001) had mother cows of the imported Black-White compared to the Slovene (6 514 ± 1 142 kg) ones. There were no statistically significant differences, in the milk production and quality of milk, between the imported mothers of first calving cows of Simmental breed comparing with Slovenian mothers of first calving cows of the same breed. The milk production between the mothers and their Simmental daughters had a statistically significant correlation (rp = 0.125 P ≤ 0.01). The higher correlation coefficient for this characteristic was established between the Black-White mothers and their daughters (rp = 0.302 P ≤ 0.001). Among the milk production of first calving cows and protein content in milk a statistically negative significant correlation (rp = -0.198 P ≤ 0.001) was established. This result confirmed that the purchase of more expensive animals with better genetic potential is economically unjustified for the breeder who does not reach intensive technology of basic quality voluminous fodder. Cilj istraživanja bio je utvrditi, da li su krave u prvoj laktaciji stranog podrijetla usporedive s kravama prve laktacije iz slovenskog uzgoja. Analizirano je 1 070 krava simentalske i holstein pasmine u prvoj laktaciji i jednaki broj njihovih majki. Po podrijetlu krave su bile iz Slovenije, Nizozemske, Njemačke i Danske. Nismo utvrdili statistički signifikantne razlike u proizvodnji i sastavu mlijeka između stranih i domaćih krava u prvoj laktaciji. Statističko signifikantno (P ≤ 0,001) višu mliječnost imale su majke holstein pasmine iz uvoza (8 004 ± 981 kg P ≤ 0,001) u usporedbi sa slovenskim (6 514 ± 1 142 kg). Kod simentalske pasmine stranih i slovenskih majki nije bilo statistički signifikantnih razlika u proizvodnji i sastavu mlijeka. Utvrđena je signifikantna korelacija (rp = 0,302 P ≤ 0,001) između mliječnosti majki i njezinih kćeri kod simentalske pasmine. Viši korelacijski koeficient za to svojstvo utvrđen je između majki i kćeri holstein pasmine (rp = 0,302 P ≤ 0,001). Utvrđena je negativna statistički signifikantna korelacija (rp = -0,198 P ≤ 0,001) između proizvodnje mlijeka krava u prvoj laktaciji i sadržaja bjelančevina. Ovi rezultati pokazuju, da je nabava skupih životinja s boljim genetskim proizvodnim potencijalom ekonomski neopravdana za proizvođače, koji ne mogu savladati tehnologiju intenzivne proizvodnje voluminozne krme visoke kakvoće.

Diplomsko delo obravnava nadomestno gradnjo hleva – študija primera. V prvem delu smo predstavili postopke za pridobitev gradbenega dovoljenja, različne sisteme reje krav ter pogoje za izgradnjo hleva. V okviru rezultatov smo predstavili stari hlev s sistemom na privez in novi hlev za rejo prostih goved na kmetiji Berdnik. Analizirali smo nadomestno gradnjo hleva s sistemom reje prostih goved in poskušali ugotoviti, ali je izgradnja le-tega zadostila vsem zahtevam, zakonodaji in željam lastnikov. Izvedli smo tudi analizo materiala, ki je bil uporabljen pri gradnji, ter ugotovili, da se živali v betonsko-leseni konstrukciji hleva dobro počutijo, so zdrave in vitalne. Prav tako smo podali ocenjeno vrednost investicije. Thesis deals with the construction of a replacement barn - a case study. In the first part, we present the procedures for obtaining building permits, various systems of rearing cows and conditions for the construction of the barn. In terms of the results we have presented an old barn with a system to berth and a new barn for free rearing cattle on the farm Berdnik. We have analyzed the alternative construction of the barn with a system of free cattle rearing and try to determine whether the construction thereof meet all the requirements, legislation and the wishes of the owners. We made an analysis of the material, which was used in the construction, and noted that the animals into the concrete-wooden structure barn feel good they are healthy and vital. We have also made the estimated value of the investment.

Cilj raziskave je bil spremljanje podatkov na klavni liniji za naključne skupine bikov po pasmah. Primerjali smo klavne lastnosti bikov iz progenega testa z naključno izbranimi biki na klavnih polovicah bikov različnih pasem v starostni kategoriji A. Poskus je bil opravljen v klavnici Celjskih mesnin in v Košakih. Po zakolu in tehtanju toplih polovic je bil trup razvrščen v klavni razred (mesnatost in zamaščenost). V hladilni komori smo opravili meritev dolžine trupa in prsne globine. Zaklanih je bilo največ bikov lisaste pasme (153), ostale pasme pa so zastopane 1 do 3 %. Največjo dolžino trupa in maso polovic so imeli biki pasme šarole (CHA),pri meritvi prsne globine ni bilo ugotovljenih večjih odstopanj med pasmami. Najmlajši v zakol oddani so bili pitanci lisaste pasme (LS-1 iz progenega testa). Biki mesnih pasem niso dosegali klavne pasemske zrelosti (datum zakola tik pred prekategorizacijo trupa v B razred). The aim of this research was to monitor data on slaughter carcass line in slaughterhouse for random groups of bulls breeds. We are compare slaughterous quality from progeny test with coincidental selected bulls on halfs of bulls body variety breeds. Experiment were done in slaughterhouse Celjske mesnine and Košaki. After slaughter and weighing warm carcass body is achived a ranging carcass body in slaughterous class (fleshiness and fatness) In cooling room we are execute to measure lenght carcass and breast depth. In slaughter was been most simental bulls (153), another breeds are deputizing 1 to 3 %. The biggest lenght carcass and body mass have got bulls charolais breeds, at measure breast depth is not bigger deviation of breeds. The youngest bulls in slaughterhouse are been simental bulls (LS-1 from progeny test). Bulls of meat breeds did not reached slaughterous species ripeness (slaughter day is close by over categorize carcass in class B).

V raziskavi smo analizirali podatke o rastnosti in klavnih kakovostih mladih bikov, starih do 24 mesecev. Podatki so vključevali starost ob zakolu, živo in toplo maso trupa, oceno konformacije in zamaščenosti po EUROP klasifikaciji, neto dnevni prirast (tople mase trupa) in dnevni prirast v obdobju pitanja. Z narejeno raziskavo med 2069 pitanci lisaste pasme, ki smo jih uvozili iz petih različnih držav (Madžarske, Romunije, Slovaške, Češke, Poljske), smo ugotovili, da je povprečna masa toplih polovic 373,5 kg, da maso tople polovice 320—420 kg dosega 73 % vseh pitancev. Več kot 85 % pitancev je razvrščenih v tretji (3) razred zamaščenosti. Po sistemu EUROP je 53 % pitancev v razredu R ter 38,7 % v razredu U. Povprečna intenzivnost pitanja je znašala 640 g/dan prirasta klavne mase. Najboljši neto prirast je bil 663 g/dan v letu 2004, pri starosti 567 dni in masi toplih polovic 373 kg. Sledilo je leto 2006, 648 g/dan prirasta tople mase pri starosti 580 dni, dosežena masa tople polovice je bila 372 kg. Leta 2005 je bilo 620 g/dan prirasta tople mase in kateri so pri starosti 609 dni dosegli maso toplih polovic 376 kg. Najboljši neto dnevni prirast 681 g/dan prirasta tople mase so dosegli biki iz Češke leta 2004. Najslabši prirast 571 g/dan prirasta tople mase je bil leta 2005, dosežen z biki iz Romunije. The aim of the study was to analyze the data on growth rate and carcass quality of young bulls under 24 months. The data comprised age at slaughter, live and warm carcass weight, conformation and fatness class according to EUROP classification system, net daily gain (of warm carcass weight) and daily gain in the fattening period. The study was carried out on 2069 Simmental bulls imported from five European countries (Hungary, Romania, Slovakia, Czech Republic, Poland). Average warm carcass weight was 373.5 kg and over 73 % of bulls reached 320-420 kg. Regarding fatness, more than 85% of bulls were classified in the third fatness class. According to EUROP classification 53% of bulls were classified in the class R and 38.7% in the class U. Average net daily gain (growth intensity) was 640 g/day. The best net daily gain was 663 g/day in 2004 at the average age of 567 days and average warm carcass weight of 373 kg. In 2006 net daily gain was 648 g/day at the age of 580 days and warm carcass weight of 372 kg. In 2005 net daily gain was 620 g/day at the age of 609 days and warm carcass weight of 376 kg. The best net daily gain (681 g/day) achieved bulls from Czech Republic in 2004 and the worst net daily gain (571 g/day) bulls from Romania in 2005.
