- Abstract
The aim of this experiment was to investigate whether brown Tsaiya duck's organs may contain genetically modified fragments or not when ducks were given feed made with genetically modified corn and soybean. Totally 78 brown Tsaiya ducks were randomly allocated into 2 treatments. There were three phases of feed including brooding period, growing period and laying period in the experiment, and the difference was the source of corn and soybean is genetically modified or not. Three randomly chosen ducks were sacrificed at 24 weeks of age, and DNA of leg meat, liver, gizzard, ovary and ileum was extracted for genetically modified fragments identification. The results showed GMO corn and soybean were screened out common CaMV35S-p, FMV-p, Nos-t, tE9, CP4-EPSPS, PAT genetically modified elements and MIR162, T25, NK603, and GTS 4-30-2, MON87701, MON89788 from corn and soybean respectively. No genetically modified elements were detected from non-genetically modified corn and soybean. The results of the DNA extracted from the two treatments of ducks at 24 weeks of age didn't screen out any transgenic fragments. The experiment results showed that there were no genetically modified genes will remain in the ducks fed diets made with genetically modified corn and soybeans.
