Abstract:

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.
