转Cry1Ac/sck基因糙米作为肉仔鸡日粮原料对肠道菌群的影响研究

Effects of Rice Genetically Modified With Cry1Ac/sck on Intestinal Microflor of Broiler Chicken

为评价转Cry1Ac/sck基因糙米作为肉仔鸡日粮原料对肠道微生态的影响。将360只1日龄肉仔鸡随机分成3组,第一组饲喂含转基因糙米日粮;第二组饲喂含非转基因糙米日粮;第三组饲喂非转基因玉米日粮,试验期42天。在21、42天时测定肉仔鸡肠道菌群情况。结果表明:在实验期内,转基因糙米对肉仔鸡肠道菌群未产生明显影响。转Cry1Ac/sck基因糙米作为肉仔鸡日粮原料对肉仔鸡肠道微生态是安全的。

To assess whether the transgenic brown rice used in broiler＇s diet had any deleterious effects on intestinal micoflor of broiler chicken,a 42-day feeding trial was employed.Three hunder sixty one-day old broilers were divided into three groups.One group was fed a diet containing transgenic brown rice and the other group was fed a diet containing corresponding nontransgenic brown rice.Three groups were fed a diet containing corn.Entericmicroorganisms at the 21 and 42 day of age were determined.No histopathological damages were detected.From this study,it was concluded that there were no adverse effects of the transgenic brown rice on the broiler chicken＇s entericmicroorganisms.The transgenic brown rice used in broiler＇s diet was safe on entericmicroorganisms of brolier chicken.
