South Island Dairying Development Centre's (SIDDC) focus is the acceleration of South Island dairying development, particularly for South Island dairy farmers.

SIDDC seeks to achieve this through the provision of a cluster of expertise, resources, and services delivering innovative, practical research, technical, education, extension and training support to dairy farmers.

The South Island Dairying Development Centre (SIDDC) is a partnership of seven key New Zealand organisations involved in South Island dairying.

Established in September 2001, the venture is a partnership between Lincoln University, DairyNZ, South Island Dairy Farmers (represented by the South Island Dairy Event (SIDE) network), Ravensdown Fertiliser Cooperative Limited, Plant & Food Research, Livestock Improvement Corporation (LIC), and recently AgResearch.
