转Bt玉米对肥育五指山猪血清生化指标及酶含量的影响

Influences of Genetically Modified Bt Maize on Serum Biochemical Parameters and Enzyme Activities in Fattening Wuzhishan Pigs

为研究转Bt玉米对肥育五指山猪血清生化指标及相关酶含量的影响,选取6月龄遗传背景相近、初始体重(29.83±1.67)kg、健康断奶五指山猪32头,随机分配到2个处理组中,每个处理组设4个重复,每个重复4头。分别饲喂转Bt玉米(转Bt玉米组)和非转基因玉米(对照组)的饲粮。试验持续60 d,于第60天采取血样。结果表明:1)转Bt玉米组血清总蛋白、白蛋白、球蛋白、葡萄糖、尿素氮、甘油三酯和总胆固醇含量与对照组间均未达到显著差异的水平(P>0.05);2)两组血清碱性磷酸酶、谷草转氨酶及谷丙转氨酶活性间也差异不显著(P>0.05)。综合认为,转Bt玉米对肥育五指山猪血清生化指标及相关酶活性都未产生不利影响。

In order to study the effects of genetically modified Bt maize biochemical parameters and enzyme activities of fattening Wuzhishan pigs, thirty-two 6-month-old healthy fattening pigs with the similar genetic backgrounds and average initial weight of（29.83±1.67） kg were randomly divided into two treatments, 4 replicates of 4 pigs each. Pigs were fed on diets containing genetically modified Bt maize（Experimental group） or non-genetically modified maize（Control one） during the period of 60 days, respectively. Blood was collected on 60 d for sampling. The results showed that：1） Serum total protein, albumin, globin, glucose, urea nitrogen, glycerin trimyristate and total cholesterol concentrations of experimental group were not significantly different from those of control one（P〉 0.05）. 2）There were no significant differences in serum alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase activities between two groups（P〉0.05）. In conclusion, there were no adverse effects of genetically modified Bt maize on biochemical parameters and enzyme activities of fattening Wuzhishan pigs.
