I'm going to answer in English, because unfortunately my French is not up to standard.
A lot of the show and companion horses that are being transported are handled and have been trained and halter broken for these purposes.
When we have, for example, yearlings, which are horses less than 720 days old, their training and their handling are minimal. In those cases, it's easier to fly them in a group and load them in a group into an air stall so they feel comfortable and safe. It's also a lot better for them, in terms of bringing stress and anxiety down. That's why we ship really, really young horses.
Slaughter horses or horses for fattening are, in our opinion, a different breed. They are a different kind of animal. Their training is also minimal, zero. It's very hard for them to be halter broken because of their posture and their structure. Maybe it would be easier to talk to the people who have the feedlots, but in our opinion it's very, very hard to start training these horses and to start getting them handled and handling them the way we do with companion and sport horses.
That's the difference. I hope that answers your question.
