Identification of species-specific DNA in feedstuffs.


Due to the menace of transmission of spongiform encephalopathies, feed components intended for ruminant nutrition must be checked for the presence of ruminant-derived materials. A sensitive method for the identification of bovine- and ovine- and also swine- and chicken-specific mitochondrial DNA sequences based on Polymerase Chain Reaction (PCR) has been developed. The specificity of the primers for PCR has been tested using samples of DNA of other vertebrate species, which may also be present in rendering plant products intended for feed manufacture. The method allows the detection in concentrate mixtures of 0.01% of the target species derived material. The identity of a sample containing 0.1% of bovine, ovine, swine, and chicken meat-and-bone meal has further been confirmed by sequencing.
