Answers

1. What is the Barbervax vaccine used for?

Barbervax® is a vaccine registered for use in sheep against barber’s pole worm (Haemonchus contortus); it has no effect against any other worm species.

2. What are covert strikes?

Small strikes that cannot be detected easily on general inspection, called ‘covert’ strikes, are quite common and can persist for some weeks before either advancing to an ‘overt’ strike—one that can be detected by a close-paddock inspection—or resolving without the need for treatment. These covert or hidden strikes are an important ongoing source of maggots that build up the fly numbers through a season.

3. When buying rams, what is recommended to avoid introduction of lice?

All newly purchased sheep, agisted sheep or sheep returning from other properties should be inspected before release onto the property. New rams can pose a significant risk, but are generally introduced only in small numbers; therefore, an automatic policy of shearing and off–shears treatment of rams for lice on arrival (use a product that will kill lice before the rams are joined) is recommended.

4. Which drenches are registered for use in milking goats?

Caprimec and Panacur 25 are the only products with a milk withdrawal time registered and can be used in dairy goats. The others have this or a similar statement: "Do not use in female sheep or goats which are producing or may in the future produce milk for human consumption".
