Effect of Intraperitoneal Transponder on the Productive Performances of Suckling Piglets

32 piglets, 1 - 4 days old and weighting between 1,400 kg and 3,950 kg, have been separated into 2 groups: 16 piglets (group T) have been electronically identified by intraperitoneal injection of a bio-glass encapsulated transponder (HDX technology, TIRIS™); 16 piglets (group C) were the control. The time requested to apply a single transponder and record the data was of 2’ 30”, on average. The health and the welfare status of the animals have been evaluated during all the experiment. The readability of transponders in group T was evaluated both in live animals at the moment of injection using a portable reader supplied by a stick antenna and at slaughterhouse, by static reading in “ante mortem” visit and by dynamic reading in “post mortem” visit. The weight of animals at the moment of injection was 2651±786 kg vs 2705±581 kg and, at slaughterhouse, 9467±1762 kg vs 9645±1804 kg respectively for T and C group. No statistic difference on productive performances of the two groups rose. The transponder showed 100% readability and recovery. The intraperitoneal electronic identification provided a foolproof method to check animal identity in productive chain, both in farm and at slaughterhouse
