=== 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).
