- Animals: sheep
- Animal Production: parasite control
- Production Systems: holistic management
New organic standards require that natural materials be used to treat parasites in sheep and lambs, but there is a shortage of information about natural wormer performance. The farmer is also interested in looking at natural resistance to parasites. She will test three natural wormers against a control group and gather weight gain and animal health data for each group. Results will be disseminated through the media, workshops, fairs, and field days.
