Signs Of Maturity In Pigs — When To Breed?

April 6, 2026

Quick Answer

Signs of maturity in pigs include the presence of visible testicles in males (typically at 6-8 months) and visible teats, a more defined body shape, and a larger size (around 100-120 pounds) in females (typically at 7-9 months). These milestones indicate readiness for breeding.

Identifying Maturity in Males

To determine the readiness of male pigs for breeding, inspect their genital area for visible testicles. This process is called “scrotal descent” and typically occurs between 6-8 months of age, depending on breed and genetics. If the testicles have descended, the male pig is likely mature enough for breeding.

Evaluating Maturity in Females

Female pigs are ready for breeding when they display visible teats, a more defined body shape, and a larger size. Typically, this occurs between 7-9 months of age, with weights ranging from 100-120 pounds. Look for these physical indicators to determine if the sow is mature enough for breeding.

Breeding Considerations

When breeding, consider factors such as the pig’s breed, genetics, and temperament to ensure a successful mating. It’s also essential to ensure that the breeding stock is healthy and free from diseases. A veterinarian’s advice can be invaluable in this process.
