Pig Reproductive Technologies and Welfare

Artificial insemination, embryo transfer and sexed semen are used widely in pig production with welfare implications for boars, sows and procedural stress.

Key Facts

Artificial insemination is used for virtually all commercial pig matings in developed countries
Boar semen collection involves stimulus training but is generally low-stress in well-managed facilities
Intrauterine deep insemination requires catheterisation and causes greater discomfort than conventional AI
Embryo transfer is rarely used commercially but is established in genetics programmes
Genetic improvement through AI can select for welfare-relevant traits including litter size and foot health

Welfare Considerations

Reproductive technologies are integral to modern pig genetics but involve welfare considerations for animals used in procedures. Welfare-conscious use selects for traits that benefit offspring welfare.

What You Can Do

Support genetics companies selecting for welfare traits alongside production performance
Advocate for welfare standards governing boar semen collection and AI procedures
Ask producers whether their genetics programme includes welfare trait selection
