For those in the drought-affected regions, don't guess or self-assess, seek advice from your local district vets. Swarms of small black house flies are increasing the risk of marking infections and pink eye.
And despite the really dry conditions, barber’s pole has caused the deaths of sheep in a region that has had only small showers of rain.

Lower worm egg counts so far this spring cements the need to monitor, and not blanket drench sheep according to the calendar.

If you have had enough rain to change the colour of the dry paddocks, do worm egg counts four weeks after the rain. Also consider that when restocking, at least 25% of available mobs will most likely be lice affected.

The focus of worm control this month is ensuring that lamb growth is not held back by worms, and planning end-of-year worm strategies.

For Merino producers yet to mark, a worm egg count of greater than 500 eggs per gram, plus scouring plus tight tucker, should not be cause for too much alarm unless paddocks are to be grazed by weaned lambs.

With the continuing dry conditions, worm egg counts are understandably modest with only the occasional weaner mob, or late lambing ewe mob with significant worm burdens.
