The use of hormone-based products in animals has become increasingly controversial over time. Oestradiol-based hormones were banned altogether in NZ in 2007 and a voluntary ban was put in place in the Australian dairy industry soon after.

This article looks at implications for the Australian beef industry should oestradiol-based hormones be banned.
