In the experiment we judged the influence of genetically modified plants on the fattening-, carcass-, and pig quality parameters. We have recorded better fattening parameters in the group fed with the GM crops. We recorded statistically provable differences in the number of the test fattening days (30 – 100 kg), in the lifelong average daily gains, in the test fodder consumption (30 – 100 kg). We have recorded better carcass indicators in the group fed without the GM plants, which was statistically confirmed in the valuable meaty parts as well as thigh portions. There were no statistically provable differences found out in the meat quality indicators between the groups.
