Abstract
Transgenic soybean is one of the most planted crops for human food and animal feed. The channel catfish (Ictalurus punctatus) is an important aquatic organism cultured worldwide. In this study, the effect of six different soybean diets containing: two transgenic soybeans expressing different types of cp4-epsps, Vip3Aa and pat genes (DBN9004 and DBN8002), their non-transgenic parent JACK, and three conventional soybean varieties (Dongsheng3, Dongsheng7, and Dongsheng9) was investigated in juvenile channel catfish for eight weeks, and a safety assessment was performed. During the experiment, no difference in survival rate was observed in six groups. The hepatosomatic index (HSI) and condition factor (CF) showed no significant difference. Moreover, comparable feed conversion (FC), feeding rate (FR), and feed conversion ratio (FCR) were found between transgenic soybean and JACK groups. Assessment of growth performance showed that the weight gain rate (WGR) and specific growth rate (SGR) of channel catfish were consistent. In addition, there were no changes in enzyme activity indexes (lactate dehydrogenase (LDH), total antioxidant capacity (T-AOC), aspartate aminotransferase (AST) and alanine aminotransferase (ALT)) in channel catfish among treatments. The research provided an experimental basis for the aquaculture feed industry to employ transgenic soybean DBN9004 and DBN8002 for commercial purposes.

Effects of Transgenic Bt Rice Containing the Cry1Ab Protein on the Gastrointestinal Health of Highly Inbred Wuzhishan Pigs after Two Generations of Feeding.

Abstract
To assess the safety of transgenic Bt rice, we evaluated the chronic effects of Bt rice carrying the Cry1Ab protein (1.64 mg/kg) on the gut microbiota and histopathology in highly inbred Wuzhishan pigs (WZSP) in a two-generation feeding study. The WZSP of the f0 ( n = 26) and f1 ( n = 27) generations were divided into GM and Non-GM groups and fed for 360 and 420 days with Bt and isogenic parent-line rice, respectively. The high-throughput 16S rRNA gene sequencing results revealed that the relative abundance of the family Enterobacteriaceae and genus Escherichia were significantly different between f1F and f1Z. The level of the genera CF231 and SMB53 in the f0Z group was higher than that in the f0F group. In addition, no abnormal histopathology changes in the main gastrointestinal tissues were found after feeding with Bt rice. In conclusion, Bt rice consumption has no adverse effects on the gut microbiota or organ function of WZSP.
