What do sexual maturity and physical maturity in pigs mean?

Sexual maturity in pigs is the period when the reproductive organs of the pig are fully developed and it has the ability to reproduce. Sows reach sexual maturity at 4 to 5 months of age, and boars reach sexual maturity at 5 to 6 months of age.

Physical maturity in pigs means that when the pig reaches sexual maturity, its body is still developing. After a period of time, the body organs have basically developed to maturity, and at this point mating can begin. This time is called physical maturity.
