Traceability Of Swine Meat: An Experience By EID+DNA In "Suino Tipico"

20 suckling piglets, "Suino Tipico Sardo" branded, at 1-7 days old and at an average weight of 2514±895 g, have been electronically identified (EID) by means of intraperitoneal transponders (HDX 32.5×3.8 mm, 134.2 kHz) and from each of them an auricle sample has been kept for DNA analysis. The readability of the transponder of each piglet has been detected by static and dynamic readings, in vivo and post mortem and was 100%. In the slaughtering chain, from each piglet, slaughtered at 29-35 days of age and at an average weight of 8902±1944 g, a second auricle sample has been kept for DNA analysis. The matching between the two samples of each piglet has been investigated by a genetic test, deploying n. 6 microsatellites ascribed in the FAO -ISAG panel for swine species. The DNA analysis of each electronically identified piglet confirmed the correspondence between the in vivo and post mortem samples. The pairing of EID+DNA can improve the traceability in the commercial net of the "Suino Tipico Sardo"
