PCR Analysis on Metabolic Remains of Transgenic Component Derived from Feed in Poultry Bogy

Abstract

Abstract: The present study aimed to probe into the metabolic remains of transgenic components derived from feed in the 8 inner organs including intestines, pancreas, esophagus, liver, preventriculus, kidney, heart, gizzard as well as muscle, blood, egg, dejecta, intestinal bacteria of laying hens and muscovy ducks fed with feed containing 20% genetically modified soybean cake. The laying hens and muscovy ducks fed by feed containing 20% genetically modified soybean cake were used as test materials. The transgenic components including CaMV35S, NOS, CP4-EPSPS derived from feed were analyzed by the qualitification PCR. These transgenic components were found only in feed containing 20% genetically modified soybean cake, but were not found in the 8 inner organs, muscle, blood, egg, dejecta, intestinal bacteria of laying hens and muscovy ducks tested. The results indicated that the metabolic remains of transgenic components from genetically modified soybean cake in feed were not found because of being digested fully. These transgenic components also don’t spread to environment through dejecta excretion. It means that the genetically modified soybean cake is safe to poultry products, human and environment.

Key words: genetically modified feed, transgenic component, poultry, metabolic remains
