Abstract
Caecal fermentation in rats fed diets containing transgenic potato tubers
Highlights
The first Polish transgenic clones resistant to a necrotic strain of potato virusY (PVYN) were obtained in the last decade (Chachulska et al, 1997)
Four transgenic clones: R1F and R2P, NTR1.16 and NTR2.27 were compared with the conventional cultivar Irga and a non-transgenic somaclone (Irga w.t.)
The lowest hydration of caecal digesta was found in groups R2P and NTR1.16, while the highest was in group R I F The highest amount of dry matter in the caecum was found in group NTR2.27
Summary
The first Polish transgenic clones resistant to a necrotic strain of potato virusY (PVYN) were obtained in the last decade (Chachulska et al, 1997). The first Polish transgenic clones resistant to a necrotic strain of potato virus. The results of our earlier studies indicate that genetically modified potato did not differentiate animal growth and feed utilization (Zduńczyk et al, 2004a) as well as serum enzymes and indices of non-specific defence of rats (Zduńczyk et al, 2004b), compared with non-transgenic tubers. The purpose of this study was to evaluate the potential influence of the transgenic potato on the fermentation processes in the caecum of rats. The transgenic lines of potato that were transformed with viral genome sequences in order to improve their resistance to a necrotic strain of potato virus Y (PVYN) were prepared at the Institute of Biochemistry and Biophysics of the Polish Academy of Sciences (Chachulska et al, 1997). The results were statistically evaluated using one-way ANOYA and Duncan's multiple rangę test
