Winter—can sheep and goats be affected by worms in winter?

A common misconception based on having fewer worm issues in winter is that frosts kill worm larvae on the paddock. This is a myth. >> Read More.

Can the Barbervax vaccine be used in goats?

from the WormBoss web site

The Barbervax vaccine is not registered for use in goats because preliminary trials aiming for registration in goats gave mixed results. However, your veterinarian can prescribe its use in goats with an “off-label” prescription. But thought must be given to a monitoring program to assess whether it is achieving the desired results. >> Read more

Fast Fact: Flywaves don't really sweep across the country

When the soil temperature is low, blowfly larvae burrowing into the soil do not develop past the pre-pupal stage. During winter, waterlogging, cold, trampling by stock, predation by ants and parasitism by minute wasps reduce the number of larvae that survive. However, as the soil warms in spring, larval development resumes.

Development is slow at first, but as the soil temperature rises the overwintering population emerges en masse in mid to late spring. If these flies encounter susceptible sheep, the next generation of flies is much more numerous. If conditions remain suitable for flystrike, these flies produce a third-generation flywave.

It is often said that flywaves move across the country. In reality, overwintering populations emerge at different times in different places depending on climatic differences, starting in the warmer areas. Although flywaves appear to move, blowflies themselves do not travel far. Flies rarely travel more than a few kilometres, so to a large extent farms breed their own flies.
