Energetska i proteinska vrednost kukuruza i sirka kao združenih useva sa sojom u postrnoj setvi

In this study, the energy and protein value of corn and sorghum were examined, as intercrops with soybeans in second croping. Both mixtures formed higher net energy value in milk and meat productionin the year when earlier sowing of crops was conducted. The greatest production of meat and milk on the basis of net energy in milk production and DCP provided the mixture of corn and soybeans. In the mixtures, increased production of meat and milk is possible based on the DCP, compared to the basis of net energy, which indicates a possibility of increasing of the corn or sorghum in the mixture. The mixtures showed that in double cropping, in conditions of irrigation, it ispossible to produce a significant amount of high-quality fodder.U ovim istraživanjima ispitivana je energetska i proteinska vrednost kukuruza i sirka kao združenih useva sa sojom u postrnoj setvi. Obe smeše su formirale veću neto energetsku vrednost u proizvodnji mesa i mleka u godini kada je obavljena ranija setva useva. Najveću produkciju mleka i mesa na bazi neto energije u proizvodnji mleka i mesa pruža smeša kukuruza i soje. U smešama veća proizvodnja mleka i mesa je moguća na bazi SSP nego na bazi neto energije, što ukazuje na mogućnost povećanja udela kukuruza ili sirka u smeši. Smeše su pokazale da je u postrnoj setvi u uslovima navodnjavanja moguće proizvesti značajnu količinu kvalitetne kabaste hrane
