How many years can pig produce piglets?

Sows (female pigs) can start producing piglets as early as 6 months of age and typically continue to be productive for about 4 to 6 years. However, their peak fertility usually occurs between 2 to 4 years of age. After this period, their reproductive performance may decline, but some may still produce piglets beyond 6 years with decreasing efficiency. Regular management and breeding practices can influence their longevity in production.
