Looks like it got hit by the truck.
It is a typical farmers' lorry shipping the babi to be slaughtered.
These lorries have only grills on the sides, but not the top, and metal grills are only high enough if the fucking babi don't jump on top of one another.
If a babi jumped on top of the backs of it's friends, it will manage to jump over the grill and off the lorry, and the driver may not know or may discover only when it is too fucking late.
In my opinion, they should compulsory require the cattle shipping trucks to have grill or at least nylon nets over the top to prevent MSK Toilet Break.
