Abstract
Variations in the skin temperature are often used as indicators of stress in animals. With advances in technology, it is now feasible to record high frequency livestock temperatures continuously for extended periods. In this study the objective was to analyse the response of pigs to different environmental conditions. The ear skin temperature of two batches of animals in intercontinental transport and housing was registered and characterized by the use of phase space diagram methodology. Eleven pigs were monitored during transport from a farm located in Reston (Canada), until their arrival at a farm in Montiel (Spain) during May 2016. After the itinerary by airplane and trucks separated with rest housing, pigs arrived to the farm after 94 hours. Fourteen finishers were monitored in one pen on a breeding farm in Villatobas (Spain) during one week in June 2017. To measure ear skin pig temperature, one logger with temperature sensor was glued to the RFID tag of each pig and placed on the inside half of the left ear. The areas and centroids of the phase space diagrams of ear skin temperaturas were used to quantify the variability of the time temperature series. It was considered analysis of full times series and time series by periods (transport modality, transport transfers and day and night). The time series pattern for each individual was analysed independently in order to identify differences between animals of the same batch. The thermal variability between animals of the same batch was higher during transport than those identified in housed animals. The maximum and minimum areas for an animal during transport were 60-77% higher than the áreas for housed animals, indicating more exposure to thermal stress during transport management.
