Prireja kopunjega mesa z različnimi genotipi piščancev = Increase of capone meat with different genotypes of chickensVolk, Marko ...V zadnjem času se daje poseben poudarek živilom, ki veljajo za zdravo in visoko kvalitetno hrano, primerno na naravni način živalim priolagojene reje. Uporabniki pripisujejo perutninskim proizvodom ... iz sonaravnih rej na splošno boljšo kakovost, zato so tudi v perutninarstvu potrebne nove usmeritve v tehnologije rej in večja pestrost ponudbe kvalitetnih perutninskih proizvodov. Meso kopunov bi zato lahko nedvmno predstavljalo enega od novih izdelkov v perutninski ponudbi. Petelinčke dveh genotipov (Prelux-G in Sulmtaler) smo kastrirali pri starosti 47 dni in jih pri starosti 84 dni preselili v hlev z izpustom kjer so imeli krmo in vodo po volji. Ob preselitvi je pasma Prelux-G imela maso 1,701 kg in Sulmtaler 1,454 kg ter konverzijo 2,57 in 3,11 kg/kg. Kopune smo redili v hlevu z izpusti in jih zaklali pri dveh starostih (163 in 198 dni). Masa živali ob drugem zakolu je bila za Prelux-G 2,906 kg in za Sulmtaler 3,100 kg pri konverziji 6,238 in 6,322 kg/kg za posamezno pasmo. Pogin pri pasmi Prelux-G je bil 4,31% in pri Sulmtaler 19,05%. V analizo pitovnih lastnosti so bili vključeni prirasti oz. telesna masa pri 156. in 199. dnevu starosti, izkoriščanje krme in vitalnost živali. Izračunali smo evropski faktor učinkovitosti - EEF, ki je pri pasmi Prelux-G znašal 136,82 in 106,14 pri pasmi Sulmtaler 104,79 in 94,58. Z rezultati tega poskusa smo potrdili hipotezo, da med genotipi obstajajo razlike v optimalni starosti kopunov za klanje in, da med genotipi obstajajo razlike tudi v pitovnih in klavnih lastnostih.Type of material - conference contributionPublish date - 2009Language - slovenianCOBISS.SI-ID - 2527368
