Inbreeding
Inbreeding is the result of mating closely related individuals. In the case of swine, there can be many situations in which a higher or a lower inbreeding can appear: crossing a parent with its offspring, crossing the offspring between them, or crossing pigs from different litters but with the same sire or grandsire... Nevertheless, the more closely related animals are, the higher inbreeding will be. Inbreeding reduces reproductive and growth performance of the animals.
