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.
