Objective: This study was conducted to compare growth performance, nutrient digestibility and meat quality of broilers fed a genetically modified organism (GMO) diet or a non-GMO diet. Methods: A total of 840 broilers with an initial body weight of 43.03 g per chick were randomly allocated into 1 of the following 2 dietary treatments lasted for 32 days (15 broilers per pen with 28 replicates per treatment): i) Trt 1, GMO maize-soybean meal based diet; ii) Trt 2, non-GMO maize soybean meal based diet. Both diets were maize-soybean meal diets. The GMO qualitative analysis, proximate analysis and amino acid analysis of the feed ingredient samples were carried out. Diets were formulated based on a nutrient matrix derived from analysis results. Growth performance was measured on day 0, 7, 17, and 32. And all other response criteria were measured on day 32. Results: The analysis results showed that the total Lys, Met, Thr of non-GMO grains were lower than that of GMO grains, the protein content of GMO soybean meal was higher than that of non-GMO soybean meal. Feed intake and feed conversion rate (FCR) were greater (p<0.05) in broilers provided with non-GMO diet than that of the GMO group from d 17 to 32. A decrease in FCR was observed in birds fed the GMO diet through the entire experiment (p<0.05). No significant impacts on blood profile, meat quality and nutrient digestibility were found in response to dietary treatments throughout the experimental period (p>0.05). Conclusion: These results indicated that non-GMO diet showed a negative effect on growth performance but nutrient digestibility, blood profile, carcass weight and meat quality were not affected by non-GMO diets.

2004년 9월부터 12월까지 경인지역으로 수입되는 원료농산물 및 가공식품에 대하여 유전자재조합성분 함유여부 및 유전자재조합식품 표시제 이행실태를 확인하기 위하여 모니터링을 실시하였다. 분석방법은 유전자재조합식품 검사지침에 따랐으며, 콩류가공품(원료콩 포함) 64건, 옥수수 가공품(원료 옥수수 포함) 52건, 콩 및 옥수수 함유식품 4건 등 총 120 건을 분석대상으로 하였다. 분석결과 콩을 원료로 하는 콩류가공품 1건, 콩 및 옥수수 혼합 가공식품 1건 등 총 2건에서 유전자재조합 콩인 round-ready soybean 성분을 확인 할 수 있었다. 그러나 유전자재조합 옥수수 (Bt11, GA21, T25, E176, Mon810)를 포함하는 가공식품은 확인되지 않았다. 그리고 콩 가공품 3건, 옥수수가공품 8건, 콩 및 옥수수가공품 1건 등 총 12건에서는 내재성유전자를 확인할 수 없어 검사불능으로 판정되었다. 유전자재조합성분이 확인된 시료 2건은 구분유통증명서를 구비하고 있었으며, 검사불능 시료의 경우 대부분 옥수수전분을 포함하는 제품으로 확인되었고, 추출된 유전자를 양상을 분석한 결과 크기가 300 bp 이하로 절단되어 PCR법을 이용한 분석 시 주형유전자로 사용하기에는 충분 하지 않은 것으로 판단된다.

This study was done to compare the effects of the dietary supplementation of non-genetically modified organism (non-GMO) beet pulp and canola meal on reproduction performance in gestation-lactation sows. A total of 16 lactating sows (Landrace × Yorkshire) were randomly allotted to 1 of 2 dietary treatments with 8 replicates per treatment. Treatments consisted of genetically modified organism (GMO) basal diet (CON) and GMO basal diet supplemented with Non-GMO beet pulp and canola meal (NO). The experiment lasted from 4 weeks prior to farrowing, to day 21 of lactation. The ambient environments in the dry sow accommodation and the farrowing house were kept at a fairly constant temperature of 19 - 21℃, and 60% relative humidity. In the current study, inclusion of non-GMO feed ingredients diets showed comparable effects on the reproductive performance of the sows as that of the basal diet. There was no difference in reproduction performance in sows fed the non-GMO diets compared with CON diets when the feed ingredients were replaced with the feed by-product sugar-beet pulp (SBP) and canola meal (CM). In addition, there was also no significant difference in the growth performance of the piglets fed Non-GMO diets compared with the CON diet (p > 0.05). In conclusion, the results of the current study indicate a comparable effect of non-GMO sugar-beet pulp, and canola meal diet with basal diet on reproduction performance in gestation-lactation sows.

유전자변형(GM)작물의 안전에 대한 논란은 우리나라를 포함한 많은 나라들이 GM 식품의 강제적 표시제를 도입하게 하였다. 본 연구의 목적은 어떤 수준의 열, 압력, 및 산 처리가 정성 PCR과 LEST 방법의 검출 한계 아래까지 GM 콩 혼합물의 DNA나 단백질을 파괴할 수 있는지를 조사하는 것이었다. 결과는 열처리나 고압열처리는 처리 시간에 따라서 도입유전자의 검출이 되지 않을 정도로 DNA와 단백질을 작은 절편들로 파괴함을 보여주었다. 흥미 있는 점은, 가공식품을 위한 LFST의 검출력은 약하게 가공처리된 콩에서 증가하였다. DNA 및 단백질 검출법 모두 $121^{\circ}C$, 1.5기압에서 20분 동안 처리한 후 GM 혼입물의 검출력을 거의 상실하였다. 본 연구의 결과는 시중에 유통되는 어떤 종류의 가공식품이 GM 작물 식품으로 표시되어야 할지를 결정하는데 유용할 것이다.
