Answers

1. Docking the tail to the correct length is crucial in minimising stain around the breech and reducing flystrike risk throughout the sheep’s life. What is the recommended tail length?

The recommendation is to dock the tail at the third palpable joint or to the tip of the vulva in ewes.

2. Why should winter-spring drop lambs/kids always be drenched at weaning in the moderate to high rainfall areas?

Lambs and kids should be given a weaning drench because they have little natural immunity and are stressed by the process of weaning, so that they are highly susceptible to worms. This can be compounded if their nutritional needs are not met.

3. Will Long wool treatments eradicate lice?

Long wool treatments will not eradicate lice, sheep will need to be treated again after their next shearing. The Long Wool Tool in LiceBoss can help you to decide whether it makes better economic sense to muster the sheep and apply a long wool treatment, or to wait and treat the sheep after they are next shorn.

4. In multi-active drenches, what is the difference between a combination and a mixture?

A combination contains two or more active ingredients that each target the same worms. The chance of a worm being resistant to all active ingredients in the combination is much lower than for each individual active on its own.

A mixture contains two or more active ingredients, but the actives target different worms. These give the convenience of a single drench when quite different worms are targeted; however, they should be considered 'single-active' against each worm.
