摘要

在过去的几年里,动物营养已经面临着转基因生物(GMO),它们的重要性将在未来增加。本研究对转基因苏云金芽孢杆菌Bt玉米与相应的非转基因杂交玉米Cesar的实质等效性以及对家禽、猪和反刍动物的消化率和能量含量等营养生理参数进行了研究。分析的玉米样品和青贮样品的结果表明,所有被调查的成分,如粗营养素、氨基酸、脂肪酸、矿物质和非淀粉多糖,都是相当的。对家禽、猪、奶牛和育肥牛的试验结果不受玉米转基因的影响。家禽、猪和天气的消化率和能量含量测定值不受玉米品种的影响。公牛增肥实验的检验参数和屠宰结果都没有显示饲喂由非转基因玉米和转基因玉米制成的青贮饲料的公牛之间有任何显著差异。

Genetically modified feeds in animal nutrition 1st communication: Bacillus thuringiensis (Bt) corn in poultry, pig and ruminant nutrition
During the last few years, animal nutrition has been confronted with genetically modified organisms (GMO), and their significance will increase in the future. The study presents investigations on the substantial equivalence of the transgenic Bt (Bacillus thuringiensis) corn and the corresponding nontransgenic hybrid Cesar and parameters of nutrition physiology such as digestibility and energy content for poultry, pigs and ruminants. The results of the analysed corn samples as well as of the silage samples illustrated substantial equivalence in all investigated ingredients, such as crude nutrients, amino acids, fatty acids, minerals and non‐starch polysaccharides. The results of the experiments using poultry, pigs, wethers and fattening bulls were not influenced by the genetic modification of corn. The determined values for the digestibilities and the energy contents for poultry, pigs and wethers were not affected by the used corn variety. Neither the examined parameters of the fattening experiments with bulls nor the slaughter results showed any significant differences between the bulls fed on silages made from the nontransgenic or transgenic corn.
