【 摘 要 】

The aim of this study was to evaluate the cumulative effects of using genetically modified and organic soybean in two generations of rats. Two consecutive generations of 64 Wistar rats denominated F0 and F1 were used. The animals from each generation were divided into three groups (n=8) and fed chow made of organic soybean, genetically modified soybean and casein. The PER, NPR and CAE were determined. ANOVA was applied to the results. In both the generations, a statistically significant (p<0.05) difference was found between the experimental groups and the control group. The organic soybean supplement with L-cystine provided a better use of this protein in comparison to the genetically modified soybean protein, which demonstrated that the soybean maintained its protein use, although always inferior to casein. Thus, soybean should be used with caution during the growth stages because even with supplements, it remained inferior in relation to the casein group.
