herbicide-tolerant crops and crops protected against common pests however, in some experiments, GM crops with enhanced nutritional properties were assessed. Most of these studies were carried out with GM plants with improved agronomic traits, i.e. The number of peer-reviewed papers on studies evaluating the influence of feeding food-producing animals with genetically modified materials is high. This paper reviews and discusses the results of recent experiments on the effects of feeds derived from genetically modified plants (GM feeds) on the physiological and metabolic indices of livestock, poultry and fish. Despite the facts that GM plants have been used as feed for years and a number of feeding studies have proved their safety for animals, they still give rise to emotional public discussion. The majority of GM plants are used as feed material for food-producing farm animals. The land area devoted to the cultivation of genetically modified (GM) plants has increased in recent years: in 2012 such plants were grown on over 170 million hectares globally, in 28 different countries, and are at present used by 17.3 million farmers worldwide.
