Infrared thermography as a non-invasive method to quantify the heat stress response in weaned piglets after road transport in a semi-arid region.

Heat stress (HS) is one of the main factors associated with welfare concerns during animal transport. The use of infrared thermography (IRT) for digitally monitoring HS in weaned piglets during transportation in a semi-arid region was investigated in the present study. A total of 60 focal piglets (25 ± 2.
