Expanding chilled lamb markets are increasingly looking to NZ as an all year round supplier of product. To achieve this in increasing quantities, changes to traditional lamb production patterns are required. It is up to the meat exporting companies to provide the monetary incentives to farmers for change. While on-farm changes may result in less total physical product, they will achieve for some farmers in climatically suited areas a higher net return; ie less production but a higher price for the type and timing of the product to satisfy market requirements.
