"After 3 December, all people responsible for the welfare of pigs must ensure that mated sows and gilts (young female pigs expecting their first litter) are not confined in stalls during pregnancy. The use of mating stalls for service is permitted, for no longer than 1 week," says Dean Baigent, Director of Compliance at the Ministry for Primary Industries.
The Code of Welfare for pigs was developed by NAWAC under the Animal Welfare Act 1999, and issued in 2010 by the Minister for Primary Industries.
The 2010 Code contains a minimum standard outlining this new requirement from 3 December 2015.
