Results of the study indicate that feeding
genetically modified RR soybean meal and Bt maize to
pregnant and lactating sows did not significantly affect
their condition during reproductive cycle and the
quality of their litters. Piglets rearing indices also
remained unchanged. The studies conducted by Walsh
et al. (27) on sows receiving mixtures with GM or not-
GM maize showed a similar body weight at the
beginning and at the end of pregnancy, as well as a
similar backfat thickness for both treatments.
Moreover, the average daily body weight gains of their
nursing progeny were not affected by maternal feeding.
Similar results were observed by Buzoianu et al. (3),
