What’s the story with genetics for worm management? Aren’t worm-resistant sheep poor performers? What’s the difference between resistance and resilience? Who’s CarLA (hint: It’s not your sister’s mate from Temuka). Resistant sheep have high immunity to worms and pass less worm eggs in their faeces. Resilient sheep continue to grow and perform despite worm challenge. Both traits are being measured and selected by NZ sheep breeders – you can buy rams that will improve these traits in your flock. …

In a global context the New Zealand beef and lamb sector is unique, we have an export profile like no other (more than 90 per cent of our sheepmeat and beef goes overseas), we are niche producers (we can only feed 30 million people) and our production is based on natural farming systems. … We know that competition in the meat market is strong and new competitors are emerging. This means that as a sector we need to work harder than anyone else in the world markets – we need to know our consumers …

Internal parasites and drench resistance are serious threats to livestock production. To help farmers, B+LNZ Research has launched livestock parasite management groups across the country to promote best practices and improve control strategies.  … Background Internal parasitic diseases limit livestock production and affect animal health and welfare. Drenches are failing on an increased number of farms with farmers needing support to increase their knowledge and confidence in parasite management …

Disease prevention and control require regular attention to stock health, knowledge, planning, good record keeping and compliance with domestic regulations. Explore recommended practices and specific diseases and issues below. … Recommended practices Prevention Prevention is hugely important: develop a farm animal health plan or calendar with your veterinarian. This will include vaccination and drench programmes appropriate to the needs of your farm business. Consider buying stock on the basis …

The aim of this study was to provide an understanding of introducing refugia into a lamb finishing operation that had a triple drench resistance issue. Refugia, introduced through lambs with susceptible parasites, was compared to the more conventional practice of quarantine drenching. … Background Resistance of parasites, or worms, to all classes of drench is a major concern in New Zealand farming systems. Intensive finishing and hogget grazing systems are at high risk of developing triple …

Crop types and worms … Does method of crop establishment matter? … Do crops have less worm larvae on them? What’s the best crop for low worm challenge? What if there’s lots of grass through my crop? Learn about worm challenge on different forage types, and approaches to managing worms and drench inputs while animals are grazing crops.  … Why crops?  Crops not only provide a less favourable habitat for worm larvae, but can also provide better nutrition, to grow young stock more quickly through …
