Abstract
GM maize with acquired resistance to the European corn borer and other Lepidopteran pests - MON 810; GM maize with resistance to Lepidopteran and corn rootworm larvae and with tolerance to glyphosate - MON 88017 x MON 89034; GM maize with resistance to Lepidoptera and tolerance to glyphosate - MON 89034 x NK 603 were compared with their isogenic lines. All tested samples of maize were grown in equal climatic and soil aggregate conditions. Nutritional value of GM maize was tested on model animals - rabbits, which were fed 12% share of corn in feed mixture during full terms of fattening. No influence of GM maize on growth, feed conversion, parameters of fermentation process in the cecum of rabbits and on animal health was determined. In meat of rabbits that are handed feed mixtures with contents of GM maize, determined are equivalent values of pH, contents of protein, fat, energetic values, essential amino acid and the fatty acid profile as in meat rabbits, that were served feed mixture with izogenic maize lines. Maize grain is used in nutrition of ruminants for the high content of starch, but also for important contents of crude protein. For GM maize MON 89034 x NK 603, izogenic maize and 3 references hybrids, effective degradability dry matter, crude protein, organic matter and NDF were determined. Obtained results indicate there are no differences between GM and izogenic maize.
