Integration of non-chemical control of parasitic nematodes in organic small ruminants was developed. These included use of sericea lespedeza (SL), copper oxide wire particles (COWP), FAMACHA and selective deworming, and forage systems. SL supplementation or grazing both led to reduced parasite infection and need for deworming; coupled with COWP, no chemical deworming was necessary. Annual forages may not fit in well with organic principles if a prepared seed bed is necessary; however, increasing the protein in the pasture through the use of legumes reduced the need for deworming. Rotational compared with continuous grazing also reduced the need for deworming.
Project objectives:div style="margin-left:1em;">
- 1. Examine the use of sericea lespedeza and other condensed tannin-containing plants, as fresh or dried forage (hay, pellets), for gastrointestinal nematode control in sheep and goats.
2. Examine alternative forage systems for organic and grass-fed small ruminants to decrease gastrointestinal nematode infection and increase weight gains.
3. Test integrated, forage-based gastrointestinal nematode control systems for organic and grass-fed small ruminant production on-farm.
4. Complete impact assessment of non-chemical gastrointestinal nematode control techniques on small ruminant producers.
