What is the ruling on tying up oxen for fattening for 5 or 6 months or more in a confined space (90 cm or less), which prevents them from moving and warding off insects, and sometimes leads to swelling of their limbs, knowing that not tying them prevents their fattening?

It is forbidden to torture or harm animals, such as by imprisoning and starving them, beating them unnecessarily, or branding them on the face; due to the prohibitions reported concerning such acts. It is permissible to tie an animal provided it is supplied with food and drink. Tying is not considered harm if the rope is not excessively tightened on the animal to the point of causing it pain.
