Whilst not condoning the actions,
I know what it's like to work with livestock,
It isn't always possible to carry out the work with an animal weighing in excess if half tonne, in a safe way by the book, I challenge those wgi are horrified to try it,
The kicking if calves to me looks Like it was just and light kick to get the calf to get to it's feet, action I've seen all vets do , it didn't appear to be full force, brutal kicking.
