AB  - In order to keep milk production economically effective in contemporary business environment, it is necessary to use appropriate types and combinations of animal feed. This means that the bulky part of the meal for the cows has to be based on the use of corn silage, with the addition of small amounts of alfalfa hay. This combination of forage allows for high milk production per cow, while keeping production costs low. However, this concept of nutrition is related to high investments in appropriate facilities for the storage of animal feed. To evaluate the economic effectiveness of investments in modern feed storages, a method of present value of investment is used. Determined present value of investment is compared with the corresponding construction costs of the objects at different prices of animal feed and various assumed losses due to its inadequate storage.
AB  - Da bi u savremenim uslovima poslovanja proizvodnja mleka bila ekonomski opravdana, neophodno je koristiti odgovarajuće vrste i kombinacije stočnih hraniva. To znači da se kabasti deo obroka za krave mora zasnivati na korišćenju kukuruzne silaže, uz dodatak manje količine sena lucerke. Ovakva kombinacija kabastih hraniva omogućava visoku proizvodnju mleka po kravi, uz održavanje troškova proizvodnje na niskom nivou. Međutim, navedeni koncept ishrane vezan je za visoka investiciona ulaganja u odgovarajuće objekte za smeštaj stočne hrane. Da bi se utvrdila ekonomska efektivnost investicionih ulaganja u moderne objekte za čuvanje stočne hrane, korišćena je metoda prinosne vrednosti investicije. Utvrđena prinosna vrednost poređena je sa odgovarajućim troškovima izgradnje navedenih objekata, pri različitim cenama stočne hrane i različitim pretpostavljenim gubicima usled njenog neadekvatnog skladištenja.

AB  - Creation of machinery rings in the Republic of Serbia is a topic that attracts scientists of different profiles. This form of interest association is particularly important for small farmers. Appropriate direct and indirect incentives encourage the creation of stakeholder associations of small farmers. In the most part, after the 2000th year, these incentives are implemented through projects in agriculture financed from international sources. The aim of this paper is to analyze the experiences, challenges and opportunities for further development of machinery rings. Interesting association of small agricultural producers have effects on increasing competitiveness at the micro level which is essential for the growth of export performance of agricultural and food products. The analysis results show that in the Republic of Serbia in the period 2000th-2009th there are some positive experience, but there are significant opportunities for further development of machinery rings.
AB  - Stvaranje mašinskih prstenova u Republici Srbiji je tema koja zaokuplja naučnike različitih profila. Ovakav oblik interesnog udruživanja je posebno važan za male poljoprivredne proizvođače. Odgovarajućim direktnim i indirektnim podsticajima podstiče se stvaranje interesnih udruženja malih farmera. U najvećoj meri, nakon 2000. godine, ovi podsticaji su realizovani kroz projekte u poljoprivredi finansiranih iz međunarodnih izvora. Cilj ovog rada je da se analiziraju iskustva, izazovi i mogućnosti za dalji razvoj mašinskih prstenova. Interesno udruživanje malih proizvođača ima efekte na povećanje konkurentnosti na mikro nivou što je ključno za rast izvoznih performansi poljoprivredno-prehrambenih proizvoda. Rezultati analize pokazuju da su u Republici Srbiji u periodu 2000.-2009. godine stečena određena iskustva, ali da postoje značajne mogućnosti za dalji razvoj mašinskih prstenova.

AB  - Bearers of cattle production in Serbia are small family farms. Such farms should change significantly their business operations in order to be competitive and to enable existence in future. That implies cattle breading in modern barns, use of modern equipment and nutrition improvement. However, to achieve such goal significant investments are needed. The most common production type at Serbian family farms is combination of milk, heifers and steers production. Comparing to other cattle production types, this production type requires very high investments. At the same time, such investments are connected to significant risks. The risks are caused by fluctuations of milk price, steer price, fodder costs etc. To evaluate economic effectiveness of investments in above mentioned farm type, on appropriate model were applied dynamical methods for investment evaluation. In addition, financial feasibility of investment was examined, assuming the most unfavorable financing conditions. To evaluate economic effectiveness of investment in risky circumstances, certainty equivalent method has been used. This method is not prominent and adequately used in our scientific and professional practice.
AB  - Nosioci govedarske proizvodnje u Srbiji su sitna porodična gazdinstva. Da bi ova gazdinstva u budućnosti opstala i bila konkurentna, ona moraju uvesti značajne izmene u svoje poslovanje. To podrazumeva držanje goveda u modernim objektima, korišćenje savremene opreme i poboljšanje načina ishrane. Međutim, da bi se to ostvarilo neophodna su značajna investiciona ulaganja. U Srbiji je na porodičnim gazdinstvima najviše zastupljen tip proizvodnje koji podrazumeva kombinaciju proizvodnje mlijeka, junica i tovne junadi. U poređenju sa ostalim tipovima govedarske proizvodnje, ovaj tip proizvodnje zahteva veoma visoka investiciona ulaganja. Istovremeno, ovakva su ulaganja vezana sa značajnim rizicima, koji su izazvani variranjem cene mleka, cena tovne junadi, troškova stočne hrane i sl. Da bi se ispitala ekonomska efektivnost ulaganja u navedeni tip farmi, na odgovarajućem modelu su primenjene dinamičke metode za ocenu investicija. Pored toga ispitana je i finansijska prihvatljivost investicije, pod pretpostavkom najnepovoljnijih uslova finansiranja.

AB  - The research was conducted on commercial family farms in the region of Western Serbia. The objective of this study was to evaluate the performance characteristics and operating reliability of the used/old self-propelled John Deere 5820 harvester owned by the Mitrovic Brothers family farm. The harvester was used for preparing ZP-735 hybrid maize silage, with the average maize yield and forage moisture being 24.35 t/ha and 60%, respectively. Under operating conditions, at the lowest operating speed of 2.99 km/ha, the harvester had a harvesting capacity of 28.55 t/ha. With an increase in operating speed to 4.5 km/ha, the harvesting performance was raised to 37.40 t/h. During the season, the harvester ensiled 125 ha at an average daily efficiency of 7.25 ha. The harvester operated in a high-quality and reliable manner without any major breakdown, which suggested that used harvesters, if properly maintained, can exhibit good operational efficiency. Ensiling costs at the test field on the commercial farm were 1.54 diners per kilogram.
AB  - Istraživanja su obavljena na porodičnim komercijalnim farmama užeg područja Zapadne Srbije. Sa ciljem da se utvrde eksploatacione karakteristike i pouzdanost u radu polovnog samohodnog kombajna John Deere 5820 u vlasništvu porodične farme 'Braća Mitrović'. Kombajn je korišćen u procesu siliranja hibridnog kukuruza ZP-735, čiji je prosečan prinos iznosio 24,35 t/ha, a vlažnost mase je bila 60%. Kombajn je u proizvodnim uslovima rada pri najmanjoj brzini od 2,99 km/h ostvario propusnu moć od 28,55 t/h. Sa povećanjem brzine rada na 4,5 km/h ostvarena je veća produktivnost, koja je iznosila 37,40 t/h. U toku sezone kombajn je silirao 125 ha sa prosečnim dnevnim učinkom od 7,25 ha. Kombajn je kvalitetno i pouzdano radio bez većih kvarova, što ukazuje na to da i polovni kombajni ukoliko se pravilno održavaju mogu da ostvare dobar radni efekat. Troškovi siliranja na komercijalnoj farmi, na ispitivanim parcelama iznosili su 1,54 dinara po kilogramu.

AB  - Dairy production in Republic of Serbia is conducted primarily at family farms. However, these farms mostly posses small number of cows, so that they are not capable to apply modern technical and technological solutions concerning housing and feeding of cows. Small family farms can not purchase contemporary milking equipment; thus, they have no possibility to produce high quality milk. Therefore it is necessary to direct towards formation of large family dairy farms. Consequently, it is needed to provide sources of financing for very high investments, which are indispensable. To determine whether investments in dairy production at large family farms are economically efficient and financially feasible, appropriate model of family farm has been formed. This model was used to apply dynamical methods of investment evaluation, such as Net Present Value, Internal Rate of Return and Payoff method. It is determined that investing in large family dairy farms is economically efficient, as well as financially feasible.
AB  - Proizvodnja mleka u Srbiji odvija se prvenstveno na porodičnim poljoprivrednim gazdinstvima. Međutim, ova gazdinstva većinom poseduju mali broj krava, pa nisu u mogućnosti da primenjuju moderna tehnička i tehnološka rešenja u smeštaju i ishrani krava. Mala porodična gazdinstva ne mogu nabaviti savremene muzne uređaje, pa su zato onemogućena da proizvode mleko visokog kvaliteta. Zbog toga treba ići prema formiranju krupnih porodičnih gazdinstava za proizvodnju mleka. U tom cilju potrebno je obezbediti izvore finansiranja za veoma visoka investiciona ulaganja, koja su neophodna. Da bi se utvrdilo da li su ulaganja u proizvodnju mleka na krupnim porodičnim gazdinstvima ekonomski opravdana i finansijski prihvatljiva, formiran je odgovarajući model porodičnog gazdinstva. Na njemu su primenjene metode dinamičke ocene investicija, kao što su neto sadašnja vrednost, interna kamatna stopa i rok povraćaja. Utvrđeno je da je investiranje u krupna porodična gazdinstva za proizvodnju mleka ekonomski opravdano, kao i finansijski prihvatljivo.

Therefore it is necessary to direct towards formation of large family dairy farms. Consequently, it is needed to provide sources of financing for very high investments, which are indispensable. To determine whether investments in dairy production at large family farms are economically efficient and financially feasible, appropriate model of family farm has been formed. This model was used to apply dynamical methods of investment evaluation, such as Net Present Value, Internal Rate of Return and Payoff method. It is determined that investing in large family dairy farms is economically efficient, as well as financially feasible., Proizvodnja mleka u Srbiji odvija se prvenstveno na porodičnim poljoprivrednim gazdinstvima. Međutim, ova gazdinstva većinom poseduju mali broj krava, pa nisu u mogućnosti da primenjuju moderna tehnička i tehnološka rešenja u smeštaju i ishrani krava. Mala porodična gazdinstva ne mogu nabaviti savremene muzne uređaje, pa su zato onemogućena da proizvode mleko visokog kvaliteta. Zbog toga treba ići prema formiranju krupnih porodičnih gazdinstava za proizvodnju mleka. U tom cilju potrebno je obezbediti izvore finansiranja za veoma visoka investiciona ulaganja, koja su neophodna. Da bi se utvrdilo da li su ulaganja u proizvodnju mleka na krupnim porodičnim gazdinstvima ekonomski opravdana i finansijski prihvatljiva, formiran je odgovarajući model porodičnog gazdinstva. Na njemu su primenjene metode dinamičke ocene investicija, kao što su neto sadašnja vrednost, interna kamatna stopa i rok povraćaja. Utvrđeno je da je investiranje u krupna porodična gazdinstva za proizvodnju mleka ekonomski opravdano, kao i finansijski prihvatljivo.",

AB  - Using the models of family farms implementing cattle production, it has been analyzed how economic efficiency and financial feasibility of the cattle production investments is influenced by the size of family farms; the type of production; the way of securing of the land for the forage production, both under the safe and risky circumstances. During the analysis of economic efficiency the dynamical methods of investment evaluation have been used, as well as the appropriate method for risk estimation of investments. Besides, in the study has been analyzed an earlier development of the cattle production in the Republic of Serbia, its present conditions, as well as the prospective developments of the bovine production. Judging by the acquired data, it has been established that the family farms investments with a larger number of cows are more economically efficient and more financially feasible, as well as that these investments have a lower level of risk taking in the uncertain conditions of business undertakings.

AB  - Results of quantitative and qualitative maize plants analysis were presented in the paper. Analyzed maize plants were cut and chopped by hand, into pieces of app. 5 mm. In every separate sample plant part content of dry matter was measured. By qualitative analysis was determined the content of crude proteins, crude fats, crude cellulose and crude ash, and the values of BEM and metabolic net energy were calculated. Besides, additionally were conducted measurements of: plant height, stalk thickness, cob height, plants number, yield per hectare, moving speed, cut height, time duration of trailer loading, trailer weight and harvester efficiency. Apart of those, losses of chopped material during the trailer loading were measured. Examined maize hybrids contained, in the stalk up to the height of 20 cm, 83,34% moisture and less metabolic energy, only 1,47 MJ/kg, compared to the rest of the plant with 3,53 MJ/kg. High correlation dependency between moving speed and cutting height was found. It was concluded that, during the harvesting, is not necessary to limit the working speed because of losses caused by increased cutting height. Increased cutting height from 12 to 20 cm would cause increment of the working speed, mass flow and harvester efficiency. Transport trailers must have large volume of transport space because of lower transport and loading losses. The chopping length that harvester achieved has fulfilled the technological requirements.
AB  - U radu su prikazani rezultati kvantitativne i kvalitativne analize biljaka zastupljenih hibrida kukuruza. Biljke kukuruza za kvantitativnu i kvalitativnu analizu su ručno odsecane i usitnjavane na oko 5 mm. U svakom od navedenih delova uzorka određen je sadržaj suvih materija. Kvalitativnom analizom određivan je sadržaj sirovih proteina, sirovih masti, sirove celuloze i sirovog pepela, a računskim putem određene su vrednosti za BEM i metabolička neto energija. Pored toga izvršena su još i merenja: visine biljaka, debljine stabla, visina klipa, broj biljaka, prinos po hektaru, brzina kretanja, visina reza, vreme utovara prikolice, težina prikolice, propusna moć i učinak kombajna. Posebno su mereni gubici iseckane mase pri utovaru u transportno sredstvo. Ispitivani hibridi kukuruza u stablu do visine od 20 cm sadrže 83,34% vlage i najmanje neto metaboličke energije, svega 1,47 MJ/kg u odnosu na ostali deo biljke sa 3,53 MJ/kg. Postoji visoka korelaciona zavisnost između brzine kretanja i visine reza. Zaključeno je da kombajniranjem ne treba ograničavati radnu brzinu zbog gubitaka na povećanu visinu reza. Povećanje visine reza sa 12-20 cm povećala bi se radna brzina, protok mase i učinak kombajna. Transportna sredstva moraju imati veliku zapreminu utovarnog prostora jer su manji gubici pri utovaru i transportu. Ostvarenom dužinom seckanja kombajn je zadovoljio tehnološke zahteve.

It was concluded that, during the harvesting, is not necessary to limit the working speed because of losses caused by increased cutting height. Increased cutting height from 12 to 20 cm would cause increment of the working speed, mass flow and harvester efficiency. Transport trailers must have large volume of transport space because of lower transport and loading losses. The chopping length that harvester achieved has fulfilled the technological requirements., U radu su prikazani rezultati kvantitativne i kvalitativne analize biljaka zastupljenih hibrida kukuruza. Biljke kukuruza za kvantitativnu i kvalitativnu analizu su ručno odsecane i usitnjavane na oko 5 mm. U svakom od navedenih delova uzorka određen je sadržaj suvih materija. Kvalitativnom analizom određivan je sadržaj sirovih proteina, sirovih masti, sirove celuloze i sirovog pepela, a računskim putem određene su vrednosti za BEM i metabolička neto energija. Pored toga izvršena su još i merenja: visine biljaka, debljine stabla, visina klipa, broj biljaka, prinos po hektaru, brzina kretanja, visina reza, vreme utovara prikolice, težina prikolice, propusna moć i učinak kombajna. Posebno su mereni gubici iseckane mase pri utovaru u transportno sredstvo. Ispitivani hibridi kukuruza u stablu do visine od 20 cm sadrže 83,34% vlage i najmanje neto metaboličke energije, svega 1,47 MJ/kg u odnosu na ostali deo biljke sa 3,53 MJ/kg. Postoji visoka korelaciona zavisnost između brzine kretanja i visine reza. Zaključeno je da kombajniranjem ne treba ograničavati radnu brzinu zbog gubitaka na povećanu visinu reza. Povećanje visine reza sa 12-20 cm povećala bi se radna brzina, protok mase i učinak kombajna. Transportna sredstva moraju imati veliku zapreminu utovarnog prostora jer su manji gubici pri utovaru i transportu. Ostvarenom dužinom seckanja kombajn je zadovoljio tehnološke zahteve.",
