Spring is a good time for producers and their veterinarians to consider how to make parasite control programs not only effective, but also to design them to minimize resistance.
"A good plan will help keep therapy effective, while at the same time reducing the risk of development of resistant parasite strains," says Dave Wolfgang, senior research associate with Penn State Extension.
In the April 2013 issue of Penn State's Dairy Digest, Wolfgang encourages dairy producers to design a parasite control program with their veterinarian. He also provides some elements to consider when crafting an effective parasite program.
