In the last decades the increase of the swine production, because of the increasing in food consumption, has been characterized by an increase of animal concentration in great production units, making difficult to record individual data. The automatic electronic identification systems can help in illness detection and in the evaluation of physiological data, food ingestion, physical activity and impact in the environment by the production system. Electronic injectable transponders, earing tags and the image analysis are been used for electronic identification purposes. The objective of the present work was to evaluate the best body site to inject passive transponders in piglets and possible resulting infections and/or rejections and its validation by using image analysis.
