Abstract

The aim of the study was to investigate effect of transport times of up to 12 h on pigs’ welfare. An observation box was
located on the 3rd floor of the vehicle. Device to measure temperature, humidity and video camera to monitor pigs’ behaviors were fitted in the box. Eighteen measurements were performed during two seasons for 4, 8, and 12 h of transport time with three replications. Meat samples were taken from longissimus dorsi (LD) and the carcases were chilled for 24 h at +4 °C for pH determination. To determine cortisol, glucose, lactate, and creatine kinase concentration levels, blood samples were collected before
and after transport from 90 pigs and from 20 controls that were not transported for control purposes. To evaluate behavioural alterations, frequency of events and durations were considered. Highest pH24 of 5.99 +/- 0.29 occurred during summer at 12 h transport time. Cortisol concentrations elevated during short and decreased with an increase of transport time (P < 0.001). Highest and lowest
glucose concentrations for winter and summer were at 8 and 12 h transport time, respectively (P < 0.01). Concentrations of lactate and creatine kinase positively correlated with transport time (P < 0.002). Lying, sitting, rooting and vocalization behaviours correlated with transport time (P < 0.009). Certain THI values during summer surpassed normal (equal with or >74) level during loading. The pH24 value correlated with transport time during summer. Lactate and creatine kinase concentrations increased with an increase in transport time but for Glucose, highest value was at 8 h transport time.
