A significant amount of work is under way this year to update animal welfare codes and provide updated advice to farmers for issues such as heat stress, says the Ministry for Primary Industries (MPI).

MPI veterinarian and director for animal health and welfare, Dr Chris Rodwell, said early next month MPI, in collaboration with industry partners through the Farm to Processor Animal Welfare Forum, will review its work programme after recently completed shade and shelter research.

Dr Rodwell says that while mitigating heat stress in livestock is complex, MPI is confident that this pan-sector discussion will ensure a joined-up approach is taken.

"The industry has already been proactive on this issue and we are looking forward to keeping that momentum going in order to deliver the best welfare outcomes for outdoor livestock."

Dr Rodwell says it's important that all options for shade and shelter are on the table, not just man-made infrastructure solutions, such as barns.

"Ultimately New Zealand's outdoor farming system is a good thing for our animals. It allows them to behave naturally – including lying down in paddocks – and it reduces the possibility of disease spread.

"We want to ensure that during adverse weather animals have access to protection from the elements – hot, cold, or wet weather. That may be by using natural features such as trees or scrub, or artificial structures.

"As well as permanent shelter, farmers can use short-term solutions to protect animals from heat stress, altering farm management practices such as mustering and milking times, for example."

Improving regulatory standards to manage heat stress in livestock is amongst several pieces of work currently being undertaken by the National Animal Welfare Advisory Committee (NAWAC). NAWAC is an independent committee formed to give advice on animal welfare to the Minister of Agriculture and the Associate Minister of Agriculture (Animal Welfare).

Working groups are currently reviewing existing codes for dairy cattle and pigs, and a further group is about to commence work on the sheep and beef code. Amongst other things, NAWAC will be looking to strengthen the standards to ensure protection from thermal stress. These drafts will be available for public consultation later in 2021. At that time the public will be asked to provide their thoughts and feedback on the draft documents.

In other work, NAWAC is developing a code of welfare for breeding birds in the poultry industry, and for farmed fish. Further information on NAWAC's work programme can be found on their web page
