Abstract:A visual and rapid method was applied to detect Duck ingredient in meat and meat products.Build the Visual nucleic acid test strips through the design of specific primers and detect the specificity，sensitivity，the products in the market.The detection sensitivity was 0.1%.The target fragment with length as 291 bp was amplified from duck sample.There was no target fragment in other species such as chicken，quail，pig，horse，cattle，sheep，donkey，deer，camel，carrot，and cabbage et al，indicating that the primers had good specificity.Visual nucleic acid test strips method had strong specificity，high sensitivity，simple，and rapid，which is an effective molecular biological detection technique for identification of Duck ingredient.
