The meat, dairy, egg, etc. industry has no shortage of creative ways to be horrible in search of slight gains. For instance
Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period

Or one particularly bizarre one from the shrimp farming industry
Eyestalk ablation is the removal of one (unilateral) or both (bilateral) eyestalks from a crustacean. It is routinely practiced on female shrimps (or female prawns) in almost every marine shrimp maturation or reproduction facility in the world, both research and commercial. The aim of ablation under these circumstances is to stimulate the female shrimp to develop mature ovaries and spawn.[1] The practice has drawn criticism from animal welfare advocates due to concerns about pain, distress, and long-term impacts on shrimp health and behaviour.[2][3]
