What is the ruling on running over bread with a car to break it up and feed it to sheep?

Bread should be respected and not treated with disdain, as it was narrated from Aisha (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) said: "Honor bread." Scholars have stipulated that it is disliked to step on bread with one's feet. However, if stepping on it with a car is not for the purpose of disdain, but rather to break up a large quantity of bread to use as fodder for animals, and there is no better way to break it up, then there is no harm in that.
