1. In temperate winter rainfall areas, when is a first summer drench typically given?
2. What are important steps to take when considering ceasing mulesing?
3. Can new lice infestations in sheep come from goats or birds?
4. What are the key benefits from treating goats with combination drenches?
The first summer drench is generally given to all sheep and goat mobs once the pastures are haying off, usually in November or early December. Weaning of spring-born lambs and kids usually coincides with the first summer drench and all lambs and kids should be drenched at this time.
10 steps to a ceased-mulesing flock
Sheep lice do not breed on animals other than sheep (with the possible exception of goats, in very rare instances). Birds do not carry sheep lice and they do not remain in wool rubbed onto fences, trees or other structures, so these are not sources of infestation.
Combining actives can substantially slow the development of drench resistance to those actives on your farm, allowing you more drench choices for more years.
On many farms a combination is likely to be more effective than using the individual actives (unless the individual active is fully effective). This will give a better kill of the worms in your animals.
