Pigs (England): Code of Recommendations for the Welfare of Livestock: Pigs (PB7950)

Section 1 - Management

Artificial Insemination, Vasectomy and Electro-ejaculation

The Welfare of Farmed Animals (England) (Amendment) Regulations 2003 (S.I. 2003 No. 299), Schedule 6, Part II, paragraph 7 (3) lists certain exemptions from the requirement that a pig shall be free to turn round without difficulty at all times, including:

- for the purpose of service, artificial insemination or collection of semen;

provided that the period during which it is so kept is not longer than necessary for that purpose.

90. You should keep the sows in their groups until insemination, at which time they can be moved to an appropriate stall or pen and inseminated. Sows should be allowed time to settle down in the stall or pen, and then exposed to a boar in order to encourage the standing reflex before artificial insemination takes place.
91. Sows should be left undisturbed, to allow uterine contractions, for up to thirty minutes after artificial insemination (and natural service), but they should then rejoin their group in order to minimise bullying within the group hierarchy. When double insemination is used, sows may be penned separately until 30 minutes after the second insemination, but pens must allow the animal to turn round easily.
The Veterinary Surgeons Act 1966, as amended by the Veterinary Surgeons Act 1966 (Schedule 3 Amendment) Order 1988 (S.I. 1988 No. 526) prohibits the performance of a vasectomy or the carrying out of electro-ejaculation by anyone other than a veterinary surgeon.
92. Semen collection and artificial insemination should only be carried out by a trained, competent and experienced operator. Vasectomy or electro-ejaculation may only be carried out by a veterinary surgeon.
