That's a heartwarming rescue, but they could have gone about it somewhat better.
Putting the rope around the cow's neck strangles it and could have potentially even decapitated it due to its weight, even an "internal" one where the vertebrae separate. Also, for an animal of that size and weight, that's a relatively thin rope which would put a lot of pressure in a small area that could injure it.
I hope they covered that hole afterwards.
