The research was conducted to estimate the cffect of feeding pigs with genetically modified soybean meal and maize on fattening results and fate of transgenic DNA in pig tissues. Forty-eight fatteners weighing about 30-110 kg were used. All fatteners received isonitrogenous and isoenergetic feed mixtures containing, or not the genetically modified (GM) soybean meal and maize. The animals were divided into four groups: I - control (soybean meal traditional and maize traditional), II - soybean meal GM and maize traditional, III - soybean meal traditional and maize GM, IV - soybean meal GM and maize GM. The experimental diets met the nutritional requirements of growing and finishing pigs. The results showed the similar nutritive value of both feeds: GM and conventional, as well as no effect of GM components on body weight gain, feed conversion efficiency, and carcass and meat quality. The transgenic DNA was detectable in the content of the stomach and duodenum but not in the intestinal digesta, blood and other examined organs. Histopathological analysis of internal organs and muscles did not show any differences between experimental groups.
