转Bt基因水稻秸秆对小鼠血相、血生化、血液粘度的影响

Effects of Bt Transgenic Rice Straw on Hemogram,Blood Biochemistry and Blood Viscosity of Rats

将转Bt基因水稻秸秆粉与小鼠普通饲料成分按质量比1∶3混合喂养小鼠90 d,探讨转Bt基因水稻秸秆对小鼠血相、血生化、血液粘度的影响。结果表明:试验组和对照组小鼠的血相、血生化和血液流变学等相关指标均差异不显著。由此证明转Bt基因水稻秸秆对小鼠无毒副作用,该秸秆可安全地作为牛等家畜动物的越冬饲料。

The rats were fed with mixed feeds composed of straw powder of Bt transgenic rice and ordinary forage with the mass ratio of 1 ∶ 3 to study the effects of Bt transgenic rice straw on hemogram,blood biochemistry and blood viscosity. The results indicated that there was no significant difference on several parameters including hemogram,blood biochemistry and hemorheology between treatment group and control. In conclusion,the Bt transgenic rice straw had no negative effects on rats and could be used as overwintering feeds for livestock like cow.
