State Outlooks - July 2017
There are frosts on the ground, yet sheep in some areas are wormy, having picked up ‘autumn-born' larvae off the pastures in recent months, or carried over existing burdens from late summer. As pastures shorten in length due to dry conditions stock grazing closer to the ground are at greater risk of becoming infected in the weeks ahead.
If you wonder about the value of WormTests, read the case study by Kate Sawford in this month's NSW reports.
