| − | === Epidemiology ===
| + | <br> |
| − | *Goats mount a weaker immune response to gastrointestinal worms, c.f. sheep, although at the same time appear more tolerant of similar sized worm burdens
| + | <br> |
| − | *More species contribute to the periparturient rise in worm egg output (Mainly ''Ostertagia'' in sheep; ''Ostertagia'' and ''Trichostrongylus'' in goats)
| + | </b></big> |
| − | *Susceptible to ''Nematodirus battus'' (often accompanied by coccidia) and ''Haemonchus''

| − | === Drug Susceptibility ===
| |
| − | *Anthelmintics are, in general, metabolised more quickly by goats therefore a higher dose is required
| |
| − | **Levamisole needs 1.5x sheep dose rate
| |
| − | **Benzimidazoles needs 1.3x sheep dose rate
| |
| − | *Anthelmintic resistance occurs much more quickly in goats than sheep. As many nematode species are common to both hosts, sheep should not be grazed on pastures previously used by goats
| |
| − | | |
| − | | |
| − | === Approaches to Control ===
| |
| − | *Use sheep PGE control measures, especially pasture management. Use of silage aftermath to minimise anthelmintic usage and the risk of anthelmintic resistance developing
| |
| − | *Unfortunately, many goat rearers use anthelmintics excessively for example every 4-6 weeks; one treatment per grazing coupled with pasture management should be adequate
| |
| − | *Zero grazing recommended (minimise risk of resistance developing).
