EAAP 65th Annual Meeting ‐ Copenhagen 2014
Gastrointestinal nematodes (GIN) of cattle
• Several species: Ostertagia ostertagi Cooperia oncophora
• Pasture‐borne infections
• No multiplication in the host = infection level depends on number of ingested infective larvae (L3)
• Significant impact on animal health, welfare and productivity
EAAP 65th Annual Meeting ‐ Copenhagen 2014
Extensive use of anthelmintics to control GIN
Need for integrated parasite control methods:
Anthelmintic resistance in GIN of cattle
Wish to reduce reliance on anthelmintics e.g. Organic farming, low‐
input systems
• Grazing management
• Vaccines
• Breeding programs (selection of resistant animals)
