摘要

本试验旨在研究连续饲喂转Cry1Ab/1Ac基因糙米对2个世代鹌鹑生长发育的影响。选取健康的1日龄日本鹌鹑(Coturnix japonica)402羽随机分成2组,每组3个重复,每个重复67羽,雌雄混养。2组分别为转基因组和非转基因组,分别饲喂含转Cry1Ab/1Ac基因或非转基因糙米的饲粮,35日龄时从各组中分别挑选健康的体重相近的鹌鹑72羽,平均分成6个重复,每个重复3羽雄性9羽雌性,分别继续饲喂2种饲粮,饲养至91日龄。2个组85~91日龄所产的蛋分别孵化,孵化出的子代鹌鹑分别继续饲喂2种饲粮,分组及饲养管理与亲代相同。结果表明:转基因糙米中的粗蛋白质、粗脂肪、粗纤维等营养成分的含量与非转基因糙米没有显著差异(P>0.05);与非转基因组相比,转基因组亲代和子代鹌鹑的平均日采食量、平均日增重和料重比均无显著差异(P>0.05);2代鹌鹑的肝脏、心脏、睾丸和卵巢等器官指数也与非转基因组无显著差异(P>0.05)。结果表明,连续2个世代采食含转Cry1Ab/1Ac基因糙米的饲粮对日本鹌鹑的生长发育没有显著影响。

Abstract

A two-generation feeding trial was conducted to study the effects of transgenic rice containing Cry1Ab/1Ac gene on growth and development in Japanese quails (Coturnix japonica). Four hundred and two 1-day-old Japanese quails were randomly divided into 2 groups with 3 replicates per group and 67 quails per replicate. The 2 groups were genetically modified and non-genetically modified (non-GM) groups, and quails in these 2 groups were fed diets with genetically modified rice containing Cry1Ab/1Ac gene and non-genetically modified (non-GM) rice, respectively. At age of 35 d, seventy-two healthy quails with similar body weight from each group were selected and randomly divided into 2 groups with 6 replicates per group, each replicate contained 9 female quails and 3 male quails, and quails in different groups were continued to feed with the 2 diets. The duration of each generation was 91 d and the eggs of first generation in the period at 85 to 91 d of age were hatched for the next generation. The experimental design and management of the second generation was the same as the first generation. The results showed that there was no significant difference in nutrient component contents in the genetically modified rice compared with the non-GM rice (P>0.05). The results of average daily gain (ADG), average daily feed intake (ADFI) and the ratio of feed to gain (F/G) of quails in each generation showed no significant difference in each generation between different groups (P>0.05). Comparing with the non-GM group, the indexes of liver, heart, testis and ovary of quails in each generation between the 2 groups were not significantly different. The results suggest that consuming genetically modified rice containing Cry1Ab/1Ac gene for consecutive two generations has no significant effect on growth and development in quails.
