* Cows: The average lifespan of a cow is about 15-20 years. Some cows can live even longer, up to 25 years or more.
* Pigs: The average lifespan of a pig is about 10-15 years. However, pigs raised for meat are typically slaughtered much younger, usually at around 6 months old.
So, while both cows and pigs have a similar range in their potential lifespans, cows generally live longer in a natural setting.
