A multiplex Polymerase Chain Reaction (PCR) assay was applied to feedstuff analysis for the identification of the most used species in rendering plants (ruminant, poultry, fish and pork materials). Primers were designed in different regions of mitochondrial DNA (12S rRNA, tRNA Val and 16S rRNA) after alignment of the available sequences in the GenBank database. The primers generated specific fragments of 104-106, 183, 220-230 and 290 bp length for ruminants, poultry, fish and pork, respectively. The detection limit was 0.004% for fish primers and 0.002% for ruminants, poultry and pork primers. The multiplex PCR proposed in this study can be considered a valid alternative to the microscopic method for the detection of animal derived materials banned by a European Union Regulation as a preventive measure against the spread of Bovine Spongiform Encephalopathy.

D004272 DNA, Mitochondrial Double-stranded DNA of MITOCHONDRIA. In eukaryotes, the mitochondrial GENOME is circular and codes for ribosomal RNAs, transfer RNAs, and about 10 proteins. Mitochondrial DNA,mtDNA
D005399 Fishes A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D000821 Animal Feed Foodstuff used especially for domestic and laboratory animals, or livestock. Fodder,Animal Feeds,Feed, Animal,Feeds, Animal,Fodders
D012335 RNA, Ribosomal The most abundant form of RNA. Together with proteins, it forms the ribosomes, playing a structural role and also a role in ribosomal binding of mRNA and tRNAs. Individual chains are conventionally designated by their sedimentation coefficients. In eukaryotes, four large chains exist, synthesized in the nucleolus and constituting about 50% of the ribosome. (Dorland, 28th ed) Ribosomal RNA,15S RNA,RNA, 15S
D012336 RNA, Ribosomal, 16S Constituent of 30S subunit prokaryotic ribosomes containing 1600 nucleotides and 21 proteins. 16S rRNA is involved in initiation of polypeptide synthesis. 16S Ribosomal RNA,16S rRNA,RNA, 16S Ribosomal,Ribosomal RNA, 16S,rRNA, 16S
D012366 RNA, Transfer, Val A transfer RNA which is specific for carrying valine to sites on the ribosomes in preparation for protein synthesis. Transfer RNA, Val,Valine-Specific tRNA,tRNAVal,tRNA(Val),RNA, Val Transfer,Val Transfer RNA,Valine Specific tRNA,tRNA, Valine-Specific
D012418 Ruminants A suborder of the order ARTIODACTYLA whose members have the distinguishing feature of a four-chambered stomach, including the capacious RUMEN. Horns or antlers are usually present, at least in males. Goats, Mountain,Ruminantia,Oreamnos americanus,Goat, Mountain,Mountain Goat,Mountain Goats,Ruminant
D013552 Swine Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
