Nematodirus battus

What are the effects of Nematodirus battus?

  • Causes diarrhoea, weight loss, dehydration and death
  • Usually in lambs eating grass at 6-12 weeks of age
  • High-risk lambs are ones challenged concurrently by coccidiosis, newly weaned, triplets or had low colostrum intake
  • On pasture grazed by lambs last spring
  • Lamb-lamb spread, adults are immune
  • A sudden cold snap followed by a warm period causes the eggs to all hatch together after over-wintering on the pasture
  • The faecal egg count doesn't rise in a flock sometimes until days-weeks after exposure as it is larval stages causing disease, so a FEC in early spring can be a false negative if clinical signs are being seen
  • Acts rapidly and can cause high incidence of lamb mortality
