• Inhibited larval stages and benzimidazole resistant strains of Haemonchus contortus and Teladorsagia (Ostertagia) circumcincta are also controlled.

• Liver fluke (mature, immature and early immature stages down to less than 1 week of age): Fasciola hepatica • Lungworms (adult and immature): Dictyocaulus filaria

• Nasal bots (all stages): Oestrus ovis

• Ivermectin treats inhibited/arrested larvae (winter scour syndrome).

• Ivermectin is usually effective against white drench-resistant worm populations.

• Workable 27-day meat withdrawal.


Liver Fluke 

• Flat worm whose intermediate mud snail host likes warm moist conditions (e.g. wet spring/early summer).

• Larvae are typically released onto pasture in mid-late summer. Numbers can be significant. After ingestion, parasite finds its way to liver in late-summer autumn.

• Three-stage lifecycle in the liver, initial weeks most dangerous from mortality point of view. • Condition loss, reduced performance, condemned livers in abattoir, secondary infection (e.g. clostridial disease), reduced intake, poor fleece quality,

• Adult parasites reproduce which can/will cause next year’s problem – can do so in huge numbers.

Gastrointestinal Worms

• Four main worms affect sheep digestive systems – Barbers Pole Worm, Black Scour Worm, Brown Stomach Worm and Nematodirus Battus (generally spring/early summer in lambs only).

• Broadly, they disrupt digestion causing scouring, reduced intake, reduced feed efficiency, reduced thrive and mortality.

• Pre-patent period (except Nematodirus) is 3-4 weeks.

• Faecal egg (strongyle) count is useful when deciding to intervene (exept Nematodirus).
