Why does warthog mothers kill their own piglets or other piglets?

Warthog mothers may kill their own piglets or the piglets of others primarily due to resource constraints, such as limited food or habitat. By eliminating some offspring, they can increase the chances of survival for the remaining young, ensuring that those that survive have better access to maternal care and resources. Additionally, this behavior can be influenced by stress or competition in the environment, leading mothers to prioritize the survival of the strongest piglets.
