Principles for effective internal parasite management
For at least two decades, farmers have identified the sustainable management of worms (internal parasites) as one of the biggest challenges they face. They have asked for consistent messages on testing, drench selection, farm policies, grazing management and genetic solutions to worm problems.
In May 2005, Beef + Lamb New Zealand (formerly Meat and Wool New Zealand) and MPI (formerly MAF) Sustainable Farming Fund initiated the development of a national worm management strategy, named Wormwise, involving all stakeholders. The strategy was completed in December 2005. Wormwise Workshops and Factsheets were early outputs from the programme.
Beef + Lamb New Zealand Ltd is currently the sole funder of Wormwise. For more information see www.wormwise.co.nz.
