Digestibility (%)1 st WorkshopXIII International Feed Technology SymposiumResults gained for the in vitro digestibility of the dry matter of studied grained ofobserved hybrids are presented in Figure 3 [7].8887868584838281807978ZP hybridFigure 3. Digestibility of ZP maize hybrid grainThe variation of the digestibility of the grain dry matter from 81.7 to 87.8% for observedhybrids ZP Rumenka and ZP 808, respectively, indicates that these values significantlydiffer among observed hybrids. These differences are caused by the different geneticbackground, i.e. hybrid.CONCLUSIONZP 341 ZP 434 ZP 578 ZP 704wx ZP 808 ZP RumenkaResults described and discussed in the present study show not only the existence of thedifferences related to the maize grain starch grain, its structure and functional properties,components mostly affecting maize yield as a basic component in the animal feedproduction, but also the existence of differences in the digestibility of different maizestarches and the digestibility of maize grain that depends on the genetic background, i.e.hybrid. These results are comparable with results obtained in leading research centres allover the world.Considering the role and the application of starch in animal feed, its chemical structure,functional properties and the digestibility represent unavoidable and very fundamentalparameters. The most important chemical characteristic and the reason for maizeadvantage over other cereals in animal nutrition is certainly its high starch content, i.e.the high energy content. These studies are a contribution and the starting point forfurther studies of the fundamental and practical importance within the field of theutilisation of maize, the most important natural renewable raw material for our countryin the sustainable animal feed production.28
