All pigs must at least be able to lie down and stand up in their natural position.
In order to comply with these minimum requirements, the loading density for pigs of around 100 kg should not exceed 235 kg/m2.
The breed, size and physical condition of the pigs may mean that the minimum required surface area given above has to be increased; a maximum increase of 20 % may also be required depending on the meteorological conditions and the journey time.
The loading density should be relatively high to preclude injury on takeoff or landing or in the event of turbulence, although all animals must still be able to lie down. The climate, total journey time and hour of arrival should be taken into account in deciding on the loading density.
