Is it forbidden to compress expired bread with one's feet to feed it to livestock when space in the car is limited?

Originally, it is disliked to place one's foot on bread due to the disrespect it implies towards its sacredness. However, this disliking is removed in case of necessity.

This is supported by the permissibility of using animals to thresh crops to extract the grain, such as cows trampling plants to release the grains from the ear. This practice was not condemned by jurists; rather, they affirmed its permissibility and discussed the rulings stemming from it, such as renting cows and sheep for this purpose.

Likewise, Al-Shawkani issued a fatwa regarding the purity of crops when threshed by animals whose meat is not edible, as the crop originates from two pure elements: earth and water.
