Here's why:
* They are polygamous: Pigs are considered polygamous, meaning both males and females can have multiple partners.
* Social structure: While pigs live in social groups, these groups are typically not based on long-term pair bonds.
* Breeding season: Pigs have a specific breeding season, and during this time, males compete for access to females.
While pigs may show some affection and bond with specific individuals, their mating habits are primarily driven by biological and social factors that don't involve lifelong monogamy.
