[Nutrition assessment of transgenic rice]

To observe the nutrition effects between transgenic rice and non-transgenic rice.

Wistar rats were divided into three groups according to their sex respectively: transgenic rice group, non-transgenic rice group and AIN93G normal control group. They were fed with corresponding food for 28 days. Indicator as follows: food intake, protein effective ratio, body weight, body length, blood routine test, blood biochemistry test, organ index and bone density.

In male groups, expect that liver/body ratio was higher in transgenic rice group than that in non-transgenic rice group, all other indicators had no significant difference each other. In female groups, liver/body weight ratio, blood calcium and bone density were higher in transgenic group than those in non-transgenic group. All other indicators had no significant difference between transgenic rice group and non-transgenic rice group. Body weight, bone density and blood calcium were higher and liver/body weight ratio had no significant difference in transgenic rice group than those in AIN93G group.

Transgenic rice had good nutrition effects on rat development and no toxicity and adverse effects were found in transgenic rice group.
