...today’s research to satisfy the markets of tomorrow. The New Zealand Society of Animal Production has been the major NZ forum for the presentation of research results on farmed animals including: sheep, cattle, dairy, deer and goats for over 50 years. Over 500 farmers, farm advisors, veterinarians, scientists and university students are members of the Society.
