Abstract:
The aim of the study was to evaluate the physiometabolic responses to stress in hybrid suckling piglets that were weaned and transported at different ages on a paved road under two vehicle conditions: with and without a layer of straw bedding. The piglets were weaned and transported at the following ages: 8, 15 and 22 days. The duration of each trip was 1 h. The piglets in each group were further divided into two sub‐groups for two distinct experimental transport conditions: (1) over the road with straw bedding; and (2) over the same road but without straw bedding. A total of three repetitions were performed for each experimental condition. In order to assess their responses to weaning‐ and transport‐induced stress, the study evaluated a thorough physiometabolic blood profile. The 8‐ and 15‐day‐old piglets transported without straw bedding showed increases in their pCO2, blood glucose, blood lactate levels and the percentage of hematocrit, but a decrease of pO2 upon arrival (P < 0.05). In contrast, the 22‐day‐old piglets transported on the same road with straw bedding were able to re‐establish their blood concentrations of lactate, pCO2, pO2, Na+, K+, Ca2+ and pH during the trip (P < 0.05).
